106 B. S. Rogers: 



me the opportunity of examining nine specimens from the Hooker 

 Herbarium. The sheet contained ordinary-sized and dwarfed 

 plants collected by R. C. Gunn (Hooker's collector) at Circular 

 Head, Tasmania, in 1836. They are unquestionably identical 

 with the plant known as P. cucullata, Br., in this State and P. Mac- 

 kibbini, F.v.M., in Victoria. Quite recently Dr. Rendle, of the 

 British Museum, supplied me with a photograph (and some notes) 

 of the type specimen in that Herbarium. This confirms the opinion 

 I had previously formed that Brown's species and P. Mackibbini , 

 F.v.M. , are one and the same. The type comes from Port Dalrymple 

 in Northern Tasmania. 



The identity of Brown's species having thus been established, it 

 becomes necessary to give a description and a new name to the 

 plant which has usurped its place in Victoria. With the fate of this 

 plant, is also involved that of another orchid, which has hitherto 

 ranked as one of its varieties, but which, I feel satisfied, is entitled 

 to full specific rank. These will be described as P. faleata and P. 

 alpina respectively. 



It would seem appropriate here to say also a word regarding the 

 plant known as P. furcata, Lindl.. which has been recorded from 

 Victoria, Tasmania, and South Australia. Its rank lias been 

 questioned by F. von Mueller and also by Bentham. Lindley's 

 specimens came from R. C. Gunn's collection (Tasmania); so also did 

 Hooker's (Fl. Tasmania, II., 20). A careful analysis of plants from 

 the same collection has enabled me to supply the accompanying 

 illustration of P. furcata. which, together with the incidental re- 

 marks on the differential diagnosis between this and the two new 

 species, will serve to support Lindley's view that it is entitled to 

 specific rank. 



The illustrations of P. furcata, P. faleata and P. alpina are from 

 herbarium specimens. That of P. cucullata is from the living plant. 



Pterostylis faleata, sp. nov. 



Plant varying in height, usually five to nine inches. Basal leaves 

 present, seldom strictly rosulate ; ovate-lanceolate or oblong- 

 lanceolate; sessile, or almost so; 7-9 nerved; rarely exceeding 



1 A incites. Stem slender, glabrous; bracts 2 to 3, lanceolate, sheath- 

 ing, upper one usually some little distance below the ovary and 

 rarely including it. Flower solitary, glabrous, very large (often 



2 inches from top of ovary to tip of galea), green ; galea erect, very 

 acuminate, sickle-shaped ; conjoined sepals cuneate at the base.
