Erigeron bonplandii, Buch. 



A SMALL shrubby very viscid plant, 10-12 inches high. Leaves 

 numerous, linear obovate, obtuse, obscurely serrate, 2-4 inches 

 long, f -inch at the broadest part, bright-green on the upper 

 surface, and covered with close, white, shining tomentum 

 beneath. Scapes 4, in the axils of the upper leaves. Stem 

 bracts numerous, diminishing in size upwards. Heads nearly 

 2 inches in diameter, involucral scales in few series, long, linear, 

 upright. Kays long, linear; anthers tailless. Pappus of few 

 short hairs ; achene with short rigid hairs on margins. 



This very showy Erigeron was collected by Mr. Martin, on 

 Mount Bonplaud; there is a fine robust specimen growing in his 

 nursery at Green Island. The large flower-heads of this species 

 make it very attractive, and it is worthy of cultivation. This 

 species is allied to Erigeron novce-zealandia, figured in vol. xvii. 

 " Trans. N.Z. Institute," but differs much from that species in 

 its large leaves and numerous scapes. 



Celmuia martini, Buch. 



Ehizome stout. Leaf sheaths ^ inch in diameter. Leaves 

 12 inches long, ^ inch broad, obscurely serrate, linear-oblong, 

 and tapering to an acute point at top, narrowing near the 

 bottom to 1 inch, then spreading downwards into a broad 

 villous sheathing petiole ; under-surface covered with closely 

 appressed white or very pale-buff tomentum ; central vein dark- 

 purple, dividing near the bottom into nine dark-purple veins ; 

 back of leaf covered, when young, with a white silvery pellicle, 

 which afterwards breaks away, exposing the dark-green leaf. 

 Scape stout, scarcely longer than the leaves. Bracts few, 

 narrow, linear, 4 inches long, diminishing in size upwards. 

 Head nearly 2 inches in diameter. Florets numerous, long, 

 narrow, linear.
