Blue Mountains Wildflowers
Pea Flowers, Orchids, Lilies & Irises

Spotted Sun Orchid
With over 1,100 species, the
Pea Flower family (Fabaceae) is one of the largest in Australia.
There are about 1,000 species of Orchids (family Orchidaceae) in Australia and as many as 35,000 species worldwide - making it the world's largest flower family.
Most of the Australian Lily species (family Liliaceae) have recently been reclassified into a dozen or so other botanical families.
The Iris family (Iridaceae) is represented throughout the world by freesias, gladiolis and irises - and in Australia by the Genus Patersonia.

Pea Flowers - family Fabaceae
Pea flowers have five petals -
- the standard or banner
- two wings
- two petals that are usually fused together and referred to as the keel.
Bossiaea genus
Sword Bossiaea
Bossiaea ensata
This low sprawling plant has no leaves. Its green keel, and the red at the back of the standard, is a good way to identify it - see large image. Its flat
stems are 4-5mm wide; the flowers 10mm across.

Variable Bossiaea
Bossiaea heterophylla
Flowering in Autumn, this, plus its variable leaves and largish crimson keel identify it. The leaves vary on the plant and may be ovate or thin, and also
vary in size.
Daviesia genus
Gorse Bitter Pea
Daviesia ulicifolia
This common pea flower is characterised by its sharp but flat leaves and sharp branches (spines). It flowers in spring.
Clustered Bitter-pea
Daviesia corymbosa
A stunning display of dark yellow and crimson pea flowers clustered together.
Winged Bitter Pea
Daviesia alata
Its orange pea flowers and strap like leaves identify it. The flowers are 6mm wide.
Dillwynia genus
Dillwynia brunioides
Sadly, this beautiful plant has no common name. The flowers are about 13mm wide and the warty leaves 7-8mm long.
Here's another
image that shows the more usual spreading leaves.

Dillwynia elegans
The broad standard identifies it as a
Dillwynia species.
Dillwynia elegans is identified by its terete (cylindrical), glabrous
(non-hairy) and warty
leaves that have a point that is occasionally bent, and its glabrous
calyx.
It was formerly called
Dillwynia floribunda var. teretifolia.
Heathy Parrot Pea
Dillwynia retorta
Probably the most common
Dillwynia, it is recognised by its twisted
leaves
Here's another
image showing it being eaten by what looks like a weevil.
[There's an
estimated 80,000 beetle species in Australia.]
Gompholobium genus - Golden Glory Peas
There's 11 species of Gompholobium in NSW - 10 of which can be found in the Blue Mountains.
Broad-leaf Wedge Pea
Gompholobium latifolium
Identified by its broad leaves - well, broader than the Large Wedge Pea - and its
ciliate (hairy) keel.
Growing up to 3 metres in height, it is the largest of the Wedge Peas.
Dwarf Wedge Pea
Gompholobium minus
The apex (ends) of its
leaves are strongly recurved (bent) and they have a point.
Its flowers are 7mm wide.
Red Wedge Pea
Gompholobium uncinatum
Its red-orange flowers and 3-foliolate recurved
leaves help identify this small plant.
Here's another
image.
Hovea genus
There's 20 species of Hovea in NSW - 8 of which can be found in the Blue Mountains.
Common Hovea
Hovea linearis
Flowering in late winter, this beautiful pea flower is also known as the Erect Hovea or Blue Bonnet. The latter being a delightful name.
Rusty Pods
Hovea longifolia
Identified by its very hairy sepals. Its narrow leaves are up to 8cm in length.
This
image shows the distinctive underside of its leaves.
Here's another
image of Rusty Pods.
Mirbelia genus
Heathy Mirbelia
Mirbelia rubiifolia
The pink pea flowers and heavily "veined"
leaves identify this delightful small plant.
The 10-20mm
leaves are in threes along the stem.
Here's a white
variant.
Large-flowered Mirbelia
Mirbelia platylobioides
Historically called
Mirbelia grandiflora it also exhibits the heavily veined leaves of its sibling to the immediate left.
The flower is 10-12mm wide.
Here's another
image.
[Note: The name "Large-flowered Mirbelia" is not commonly accepted.]
Mirbelia baueri
The flowers are 10mm long & wide. The plant shown here had upturned wings and was prostrate; its 8-10mm leaves were smooth with a ridge on the top.
Here's another
image.
Pultenaea genus - Bush Peas
Rough Bush-pea
Pultenaea scabra
Identified by its squared-off
leaves that have weak mucro, and the tell-tale stipules that characterises the Pultenaea genus.
[Stipules are the small leafy growth at the base of leaves.]
Halo Bush-pea
Pultenaea linophylla
A small scraggy plant whose spring flowers are about 6mm across and have a red keel.
Its leaves are 10mm long, have a down-turned tip and are hairy underneath.
It is also known as the Small-leaved Bush-pea.
Pultenaea canescens
Only found in the upper Blue Mountains, it is identified by its hairy concave leaves and yellow keel. Its
bracteole is reddish brown which helps distinguish it from
P. tuberculata (which has a red keel).
Phyllota genus
There's 4 species of Phyllota in NSW - 3 of which can be found in the Blue Mountains.
Dense Phyllota
Phyllota squarrosa
Yet another stunning pea-flower. It is separated from its siblings by its
yellow mucro (leaf tip).
Its elongated standard is 8mm high, and its leaf margins revolute (rolled-back).
other peaflower genera
Purple Coral Pea
Hardenbergia violacea
Easy to identify as it is most probably the only purple peaflower climber.
Its flowers are 8mm across. Commercially it is known as the Happy Wanderer.
Here's an image of its
leaves.
Leafless Globe-pea
Sphaerolobium minus
Differentiated from S. vimineum by its shorter wings that expose its keel, and having only a hint of red on some flowers, and none on most.
The flowers are barely 5mm wide and long.
Native Holly
Podolobium ilicifolium
Easily identified by its holly like leaves, it is also known as the Prickly Shaggy Pea. Shaggy Pea being the common name of the Podolobium genus.
Handsome Flat Pea
Platylobium formosum
subsp. parviflorum
Recognised by the prominent veins on its leaves. The back of the standard is red.
Subsp. parviflorum has long leaves; whereas subsp. formosum's leaves are roundish.
Australian Indigo
Indigofera australis
Found throughout Australia, its pink flowers and grey leaves help identify it.
Gorse
Ulex europaeus
Introduced species (weed)
This declared noxious weed is identified by its very hairy keel and spines.
Orchids - family Orchidaceae.
Large Tongue Orchid
Cryptostylis subulata
Also known as the Duck Orchid due to its bill or tongue like labellum - which is around 30mm in length. The sepals and other petals are small and spike like.
Large Duck Orchid
Caleana major
Resembling a duck in flight, with its sepals for wings, its labellum as its head and its column for a body. This small orchid's labellum snaps shut against the column trapping the visiting insect and turning it into a pollinator.
Native Potato
Gastrodia sesamoides
On first appearance it looks like a withered orchid - but its light brown flowers and stems are its natural colours. Also known as Cinnamon Bells.
Pink Fingers
Caladenia carnea
A small orchid that is 20-30mm across whose colour varies from near white to dark pink.
Here is an
image showing its distinguishing characteristics.
NSW Flora Online says that
Caladenia carnea
"hybridizes with
C. catenata and
C. fuscata, so larger populations may incorporate confusing hybrid swarms."
just what the amateur
botanist wants to hear ...
C. catenata isn't found in the Upper Blue Mountains, and as far as I can ascertain -
- C. carnea's labellum lobe doesn't protrude, its labellum tip is
yellow and it tends to be pinker.
- C. fuscata's labellum lobe protrudes and its labellum tip is white,
and it is smaller.
Dusky Fingers
Caladenia fuscata
Flowering in early Spring, Dusky Fingers' sepals and petals are less than 7mm long.
Here is an
image showing its distinguishing characteristics.
Slender Sun Orchid
Thelymitra pauciflora
A small orchid about 12mm wide. Its petal-like labellum is narrower than the other petals & sepals.
Here's a paler
form.
Spotted Sun Orchid
Thelymitra ixioides var. ixioides
Also known as the Blue Sun Orchid, it has dark blue dots on its upper three segments. The flower is 25mm wide, but needs a sunny day to open.
It is best identified by the finger like
papillae as not all Spotted Sun Orchids have spots.
Small Waxlip Orchid
Glossodia minor
A small orchid that is 20mm wide. The flower stem is leafless - the leaf leaving the stem near the ground.
Tall Leek Orchid
Prasophyllum elatum
Also known as the Piano Orchid, this orchid occurs in all other Australian States except the North Territory. Its long leaf stem can be seen in the
background.
Nodding Greenhood Orchid
Pterostylis nutans
One of the more easily recognised Greenhoods due to its nodding stance. It appears from late Autumn through to Spring.
The 3-6 leaves of its
rosette have scalloped edges.
Chocolate-Lip Leafy Greenhood
Bunochilus chocolatinus
Similar to the
Tall Greenhood this Central Tableland's species is distinguished by its milk chocolate coloured labellum.
The Tall Greenhood's labellum is also hairy. There's no rosette.
The Leafy Greenhoods have been placed in a new genera -
Bunochilus
Red Beardie
Calochilus paludosus
Also known as the Red Beard Orchid, it is distinguished from its siblings by the lack of glands on its "
collars".
Its long, exposed and bent
labellum is another key.
Here's another
image.
Eastern Tiny Blue
China Orchid
Cyanicula caerulea
This small orchid is barely 20mm wide and was found in the Kedumba Valley. It is also known as the Blue Caladenia as it was until recently in the Caladenia genus.
It is the only Cyanicula species in NSW.
Bird's-mouth Orchid
Orthoceras strictum
Also known as the Horned Orchid, it is the only species in this genus in Australia.
Although the plant is about 50cm tall, its colours camouflage it well.
Here's another
image.
Lilies
Branching Fringe Lily
Thysanotus juncifolius
[Family ANTHERICACEAE]
The fringe on the petals of this small (20mm) flower is stunning.
Distinguished from the Common Fringe Lily (
T. tuberosus) by the absence of basal leaves - as this
image shows.
Common Fringe Lily
Thysanotus tuberosus
subsp. tuberosus
[Family ANTHERICACEAE]
Very similar to the Branching Fringe Lily (
T. juncifolius), but it has very long basal leaves - as this
image shows.
Rush Lily
Sowerbaea juncea
[Family ANTHERICACEAE]
Flowering in spring and liking damp heath, it is also known as the Vanilla Lily due to its scent.
It is the only species of this genus in NSW.
Here's two more images -
one showing the flower open; the
other showing the many flowers in a cluster.
Nodding Chocolate Lily
Dichopogon fimbriatus
[Family ANTHERICACEAE]
This spring and summer flowering lily has a downward facing light blue flower that is 8mm wide.
It is identified by its bent
filaments and the double appendage at the end of its anther.
Apparently it has a chocolate scent - which I will sense next season.
Here's another
image.
[The stamen consists of an anther and a filament (stalk).]
Tufted Blue-lily
Thelionema caespitosum
[Family PHORMIACEAE]
Distinguished from the
Dianella and
Stypandra genera by its upward facing flowers and coiled
anthers.
There are three species in this genus.
T. umbellatum has white flowers;
T. grande isn't found in the Blue Mountains.
The flowers are 25mm across and appear in spring and summer.
Alania endlicheri
[Family BORYACEAE]
This tiny (4 mm wide) summer flowering lily is found on damp cliff faces.
It is the only species in the genus.
Mountain Christmas Bell
Blandfordia cunninghamii
[Family BLANDFORDIACEAE]
This threatened species is distinguished from the other Christmas Bells by its many (more than a dozen in a cluster) 6cm long flowers.
It grows along cliff edges in early summer.
Milkmaids
Burchardia umbellata
[Family COLCHICACEAE]
Its umbel* helps identify it and distinguish it from other family members. This
image shows the umbel. Here's another
image.
Its flowers are 15mm wide.
[umbel* - flowers or flower stalks arise from one point.]
Agapanthus
Agapanthus praecox subsp. orientalis
[Family ALLIACEAE]
Introduced species (weed)
Spectacular large flowers in summer, it is an indestructable weed that is marching from the villages into the national park.
Its tuberous rootstock is hard to completely remove. Here's an
image of its leaves.
Also known as African Lily and Lily of the Nile.
Golden Weather-grass
Hypoxis hygrometrica
[Family HYPOXIDACEAE]
Also known as yellow stars, the flower has a 25mm wing-span.
Irises - family Iridaceae.
In NSW, there are 4 species of the Patersonia genus, all are found in the Blue Mountains.
Dwarf Purple Flag
Patersonia longifolia
It can be distinguished by its leaves - which are bluish-green, very narrow (2mm), sometimes twisted and have hairs crisscrossing them.
The flowers also seem to be a deeper purple.
Silky Purple Flag
Patersonia sericea
Its 50mm flowers appear in spring and early summer. It can be identified by the silky hairs on its spathe (bud), wider leaves (5mm) and its flower stems
coming from its
fan-like base.
Swamp Iris
Patersonia fragilis
Found in damp sheltered areas, it is identified by the lack of hairs on the flower's
spathe and the layout of the
base of the plant.
The light blue tepals are 20mm long.
Pretty Grass-flag
Libertia pulchella
Found in wet sheltered areas.
Distinguished from the Branching Grass-flag (
L. paniculata) as that plant's leaves are longer than its scape* and its pedicels (stalks) are only 1cm long.
This is shown in the full
image of the Pretty Grass-flag, and this
image showing its 3cm long pedicels.
[* scape - the stem-like flowering stalk.]
