Rogers, R. S., Notes on certain species of Pterostylis. (Proc. 

 Roy. Soc. Victoria. XXVIII. 1. p. 105—111. 1915.) 



It was recently found that the plant called Pterostylis Mackibbini, 

 J. v. M. in Victoria was really P. cucullata, Br. The species 

 formerly known in Victoria as P. cucullata, is now named P. fal- 

 cata sp. nov. Anöther orchid previously regarded as one of its 

 varieties is named P. alpina sp. nov. Both these new species are 

 described, and notes are furnished on P. furcata, Lindl. The four 

 species are illustrated, and tables comparing them are supplied.
