Prasophyllum - Leek Orchids

There are around 25 species of Leek Orchids in the south west of Western Australia. Most of these require a hot summer burn, after which they flower in profusion. There is great variety within the genus, with species ranging from the tiny Laughing Leek Orchid (P. gracile) to the King Leek Orchid (P. regium), which can reach over 1.5 metres in height with over 80 flowers.


Prasophyllum fimbria - Fringed Leek Orchid

The Fringed Leek Orchid is identified by the colourful, prominently fringed labellum. The stems are quite variable in colour from green black. The orchid will flower in unburnt bushland, but flowers in much greater profusion after a burn. It flowers from August to October.

Prasophyllum parvifolium - Autumn Leek Orchid
Prasophyllum sp. 'early' - Scented Leek Orchid
Prasophyllum sp. 'Brookton Highway' - Rare Leek Orchid

One of the first Leek Orchids to flower, starting in July, the Autumn Leek Orchid does not require a burn and reaches up to 25cm tall. Somewhat wrongly named as the orchid flowers in winter, not autumn. The Scented Autumn Leek Orchid actually does flower in autumn (April-May) and is distinguished from the Autumn Leek Orchid by its paler, scented flowers and earlier flowering time. The Rare Leek Orchid is distinguished by its later flowering period (late August-October), the pinkish colouring of the flowers and its self pollinating habit, which results in flowers seldom having more than 1-3 flowers open at a time.

Prasophyllum giganteum - Bronze Leek Orchid

The Bronze Leek Orchid (P. giganteum) and the Tall Leek Orchid (P. elatum) are very similar, distinguished mainly by the labellum. In the Bronze Leek Orchid, the inner part of the labellum is flattened and pointed, in P. elatum, it is more cupped and rounded on its top edge (see diagram).

Prasophyllum elatum - Tall Leek Orchid

The Tall Leek Orchid is distinguished from the very similar Bronze Leek Orchid by the labellum, which has a more rounded tip both of the labellum itself and the labellum inner plate (see diagram). Despite its name, the Tall Leek Orchid is not the tallest of the leek orchids, being eclipsed by the King Leek Orchid, P. regium.

Prasophyllum macrotys - Inland Leek Orchid

The Inland Leek Orchid is much the same as the Tall Leek (P. elatum) and differs by having slightly smaller, darker flowers with a pinched tip to the labellum. As its name suggests, this orchid is found inland from the Tall Leek, mainly in the central wheatbelt. It is also similar to the Bronze Leek Orchid, differing in that the inner labellum plate does not have quite so pointed a tip.

Prasophyllum gracile - Little Laughing Leek Orchid
Prasophyllum macrostachyum - Laughing Leek Orchid

The smallest Leek Orchids, the Little Laughing Leek Orchid does not require a burn and is widely distributed over south west Western Australia. In drier areas it is is confined to areas receiving extra water such as granite outcrops. The Laughing Leek Orchid is similar but has slightly larger and darker flowers. It favours swampy or winter wet habitats.

Prasophyllum gibbosum - Humped Leek Orchid

The Humped Leek Orchid is very similar to the Stout Leek Orchid and the Hooded Leek Orchid. It is identified by the frilly labellum edges, the late flowering period (Nov-Dec) and its preference for swampy habitat.

Prasophyllum sp. 'south coast' - Stout Leek Orchid

The Stout Leek Orchid has recently been recognised as distinct from the Humped Leek Orchid, P. gibbosum. It is distinguished by the straight labellum edges and earlier flowering period (Sep-Oct).

This orchid is very similar in appearance to the Humped Leek Orchid, P. gibbosum. It is distinguished mainly by its earlier flowering period (Sep-Oct) and its preference for soils on and around granite outcrops. It will flower in unburnt bushland, but flowers in greater profusion following summer fire.
