Pterostylis. 

 p. nana, Br. 



This species, though apparently less prolific in the 

 western State than in South Australia, was observed growing 

 vigorously in colonies near Albany on the erect trunks of a 

 large banksia, in one case 8 feet 6 inches above the ground. 

 The surrounding debris seemed to indicate that the tubers 

 had been lodged in this curious position by the action of 

 flood- waters during a previous season.

 Tree' School, near Jarnadup, Miss I. Knox-Peden, 31/8/20. 



This species sometimes attains a considerable size. 

 Specimens from Jarnadup District were nearly a foot (30 cm.) 

 in height, fairly stout, with no sign of rosulate leaves, but 

 numerous stem-leaves, and flowers about twice the size of 

 P. n'anu. The writer is of opinion that this species is quite 

 distinct from P. nana, Br.
