A beautiful plant. The lowen leaves are obviously 3-nerved beneath. I have not seen Canter- 

 bury specimens, and doubt the occurrence both of this and G. trinerve in alpine localities, as stated 

 by J. B. Armstrong. 



2. G. trinerve, G. Forst., Prod. n. 289. Stems lft.-2ft. long, suffru- 

 tescent, branched, prostrate or suberect, glabrate or more or less cottony. 

 Leaves distant, flat, obovate or spathulate-lanceolate, rounded at the apex, 

 acute or apiculate, glabrous and obscurely 3-nerved above^ white beneath. 

 Heads 5—10 on terminal or axillary bracteate tomentose peduncles ; involucral 

 bracts numerous, radiating, shortly clawed, the outer densely clothed at the 

 base with woolly tomentum. Achenes small, glabrous. Pappus-hairs few. — ■
