Found m sandy soil at Ravenswood, near Pinjarra, 

 Western Australia, Jean S. Rogers, 1/10/19. It was then just 

 beginning to flower. 



This Drakaea should be placed in the section where the 

 labellum is articulated at the end of a basal projection of the 

 column and where the flower is solitary. The following 

 differential table will show its relation to the two other 

 members of this section : — 

 X»amina of labellum divided into two unequal 



lobes by a constriction near insertion 



of the claw. 

 Longer lobe markedly glandular and hairy 



in basal half or third, elsewhere smooth, 



upturned at its free extremity ; shorter 



lobe hairy and very glandular. Anther 



blunt but rostellum much prolonged so 



as to simulate an anther-point D. elastica 



Longer lobe very hairy except at its ex- 



treme^ tip which is smooth but not 



upturned, non-glandular ; shorter lobe 



.very glandular but not hairy. Anther 



blunt, rostellum not prolonged D. glyptodon 



Longer lobe quite smooth except for a few 



hairs at exti^me base near insertion of 



claw, non-glandular, not upturned at 



tip; shorter lobe very glandular and 



hairy. Anther blunt, rostellum not 



prolonged D. Jeanensis 



The prolongation of the rostellar point is a very 

 characteristic feature of D. elastica, Lindl. This, together 

 with the "cocking-up" of the free extremity of the longer 

 lobe of the lamina and the free distribution of glands and 

 hairs over a considerable area of that lobe, readily serve to 

 distinguish it from the new species. The latter approaches 

 more nearly to D. glyptodon, Fitz., but here again the large 

 area of the longer lobe of the lamina covered by hair and the 

 absence of hair on the shorter lobe in Fitzgerald's species, 

 afford a ready distinction between the two plants. Further, 

 the shape of the shorter lobe of the lamina is quite different. 

 While too much reliance cannot be attached to colouring, 

 nevertheless the emerald-green leaf and the bright reddish- 

 brown tints of the flower in the orchid under review 

 immediately attract attention and differentiate it from both 

 the older species, in which the flowers appear to be con- 

 sistently dark purple. 



Prasophyllum lanceolatum, n. sp. 

 Plant rather slender, 40-77 cm. high (in my specimens) 

 Avith two long imbricated tubular sheaths at base of stem. 

 X.eaf-lamina 12-15 cm. long, not reaching as high as spike.
