Erigeron novce-zealandice, Buch. PI. xv. 



A small semi-shrubby plant 7-8 inches high, whole plant viscid. Leaves 



very narrow imbricating linear- spathulate obscurely and distantly serrate, 



1^— 2-| inches long, i- \ inch broad, obtuse or acuminate, green on the upper 



surface, 3-nerved beneath and covered with closely appressed tomentum. 



Scapes 2-3, very narrow, proceeding from the axils of the upper leaves. 



Bracts 5-7 narrow-linear, diminishing in size upwards. Heads 1 inch 



diameter, involucral scales in few series, linear, very narrow, sometimes 



recurved. Bays long, narrow, recurved in full flower. Anthers tailless. 



Pappus i inch long. Achene with short rigid hairs. 



The semi-shrubby habit of the present plant, as also of some others 

 described as belonging to G'elmisia — namely, 0. discolor, Hook, fil., and 

 C. walkeri, Kirk, indicate — especially when this habit is associated with tail- 

 less anthers, as with the plants above named — the necessity of removing 

 them to the genus Erigeron, where they will find a more natural alliance,
