TERRESTRIAL ORCHIDS - Part two

Lowland species similar to C. alpina, having pinkish coloration and being fairly common in the
south-west.


                 CALADENIA CRACENS
Caladenia cracens

 
Glossodia major GLOSSODIA MAJOR      Orchidaceae
Parson in the Pulpit   

This distinctive and attractive orchid is often the first of the prominent orchids to appear in spring and is common to abundant in dry woodlands and heathlands. The leaves are broad, pale green in colour and usually resting on the ground. There are one or occasionally two flowers on a stem. Flowers vary in colour from pale to deep mauve or rarely white. The petals and sepals are similar and the labellum is smaller but still petal-like.



PTEROSTYLIS PEDUNCULATA            Orchidaceae                                                      Maroonhood
Pterostylis peduncula

A rosette of leaves surrounding a flower stem. The flower is mostly red-brown in the upper part, and has a hood which is upright and then bent sharply forward.

The flowering stems are usually about 15cm tall.  Flowers are  faintly striped with green and white in the basal part. The lateral sepals form a V-shape when the flower is viewed from the front, with long narrow segments extending well above the hood. The labellum is barely visible from the front of the flower. 

Flowering period early Spring.    Common in damp gullies, shady forested slopes and in coastal woodlands.


 
PTEROSTYLIS NUTANS      Orchidaceae
Nodding Greenhood

Widespread and common in woodlands and heathlands, and flowering in late winter to early spring, this orchid has a rosette of leaves surrounding a flower stem. The single flower is nodding with the flower stem bent forwards just below the flower. The flowering stems are usually about 15 cm tall, and the blooms are faintly striped with green and white in the basal part and green or pale brown at the end. The lateral sepals have narrow
segments reaching just beyond the end of the hood. The sickle-shaped labellum is clearly visible unless triggered back into the hood. (Tas; Vic; NSW; Qld; SA and New Zealand)

Pterostylis nutans

Diuris sulphurea

DIURIS SULPHUREA       Orchidaceae
Tiger orchid

A large yellow orchid flower with oval petals and with two dark-brown spots on the dorsal sepal. The brown spots are especially noticeable on top of  buds which are about to open.

It has a few grass-like leaves and a robust stem of up to six flowers. The labellum, in the centre of the flower, is yellow with brown markings, which may look vaguely like stripes. Otherwise the origin of the name tiger orchid is unclear. The lateral sepals are linear and usually hang downwards without crossing. Occasionally a plant with broad brown and yellow lateral sepals is found.

It favours sandy soils and is common in woodlands and heathlands in the east, north and midlands.

Flowering period - mid to late spring.


DIURIS ORIENTIS                       Orchidaceae
Eastern Wallflower Orchid

Commonly called wallflower because its colour is a soft blend of brown, purple and yellow, like the popular garden plant of the same name. This orchid has 2 or 3 narrow grass-like basal leaves to 30 cm long.

Flowers 1-6, rather broad, about 4.5cm diameter, in a terminal raceme on an erect stem to 45cm, with 2 large clawed petals held upright like ears, a broad somewhat hooding dorsal sepal, 2 greenish long strap-shaped  lateral sepals often crossing below the flower, and a 3-lobed labellum.

Flowering October-November.
Grassy and heathy open forest and woodland, teatree scrub, coastal and near-coastal in the
north, north-east and Tasman Peninsula (south-east).
