Pescott, Notes on (lie Orchids of I'icton'a. [voy.'xxxvil. 



Prasophyllnm odoralum, Rogers, the Sweet Leek Orchid.— Not 

 unhkc the latter superftcially, except that the petals and sepals 

 are longer, and the flowers more distant on the spike. It comes 

 from Ringwood ; but possibly this and the former species arc 

 widespread, and may have been taken for Prasophyllnm patens. 



PrasopJivlliim ciUatiim, Ewart and Rees, the Hairy Leek 

 Orchid.— Collected at Green Valley, near Talbot, by F. M. 

 Reader in 1910. This is a small June-flowering species, with 

 a hairy, fringed labellum. It is only about five or six inches 

 in height, and is rare. 



Plerostylis falcata, Rogers, the Sickle Greenhood. — Has long 

 been wrongly known as P. cncidlata. The latter is a low- 

 growing species, while the Sickle Greenhood is tall, often a 

 foot in height. The flower is very large, with occasionally 

 purplish shadings. It is found from October to December in 

 moist localities in many parts of the State. 



Pterostylis alpina, Rogers, the Alpine Greenhood, was for 

 many years looked upon as a small variety of the previously- 

 mentioned Greenhood. It flowers somewhat earlier, the flowers 

 are smaller, and it is recorded from many locahties. 



Pterostylis revoluta, R. Br., the Autumn Greenhood, was 

 bracketed for many years with P. refiexa. It flowers in 

 autumn. The flower is fairly large and dainty in appearance, 

 green and purplish streaked, with a slender and almost leafless 

 stem. This is one of our daintiest and most striking Greenhoods. 

 It was first recorded from Cravensville by A. B. P>raine, and is 

 generally a mountain plant. 



Pterostylis Toveyana, Ewart. Uu- Mentone Greenhood. — 

 This was collected at Mentone by J. R. Jovey. It is a June 

 orchid, and is possibly a hybrid between P. refiexa and P. 

 concinna. It is quite small, with stem leaves. The labellum 

 is distinctly notched (bifid) on the top, but not quite so deeply 

 as that of P. concinna. 



Pterostylis Mitchelli, Lindl., and Plerostylis piisilla, Rogers. 

 — These two belong to the P. riifa, R. Br., group, all of which 

 are more or less marked with a rusty-red colour. P. ruja has 

 the rosette of leaves withered at flowering time ; the labellum 

 is m(!mbranous. P. Mitchelli has a green rosette of leaves at 

 flowering time and a fleshy labellum. The flowers of lioth 

 species are large. P. piisilla has very diminutive flowers, the 

 leaf rosette being green at flowering time, and the labellum 

 membranoiis. 



DraJicra Hunlianu. V . v. M., the Llhow Orchid. .\ notable 

 find of A. B. Iirain<t at ('ravi'nsvillc. This diininutixe orchid 

 only has another locality — at Mount Tingiriiigi, in New South 

 Wales. It is only two or three inches in height, and the illus- 

 tration herewith depicts its unique form. Sec fig. 4.
