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 sp. 'early' - Scented 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 Hooded Leek Orchid is very similar to the Humped Leek Orchid, making them very difficult to tell apart. Several features listed as identifying features in various orchid publications can sometimes be common to both species.
In short, to separate these two species requires the combination of several features. The Hooded Leek Orchid is nearly always found on granites, flowers earlier (September-October), nearly always has frilly labellum edges and usually has short stems (less than 15cm) with the flowers bunched toward the top of the stem. The Humped Leek Orchid is always found in swamps, nearly always has straight edges to the labellum, usually has taller plants (up to 35cm) and a later flowering period (October-December). Note the use of the phrase, 'nearly always.' This means that you can often find Hooded Leek Orchids displaying features specific to the Humped Leek Orchid and vice versa. Clear as mud?
