I. CoNYZA gtimmifera. R. 



Arboreous. Leaves sparse, approximate, subsessile but not decur- 

 rent, froai lanceolar to cuneate-oblong, subserrate, soft, rugose and more 

 or less woolly underneath. Peduncles axillary, solitary, drooping, one- 

 flowered : flowers globular. 



Gum-wood-tree of the islanders : it grows on the more elevated land 

 over the interior parts, to be a tree of considerable size, with short crooked 

 trunk and still more crooked spreading branches and ditrichotomous 

 branchlets. Bark of the trunk and large branches a deeper or lighter 

 brown, and smooth except for the numerous scars of the fallen leaves. 

 Leaves crowded about the ends of the branchlets, often broad-lanceolar 

 particularly in old trees ; while young, gummy and more hoary : length, 

 2-4 inches, by i of an inch to one and a half broad. 



I. CoNYZA robusta. R. 



Leaves subsessile (not decurrent,) lanceolar, crenate-dentate, rugose. 

 Peduncles axillary, solitary, length of the leaves, one-flowered. 



Bastard-gum tree the vernacular name on St. Helena, where it grows to 

 be a tree very similar to the last, and possessed of nearly the same qualities. 

 The dwarfish, very crooked antique habit of those trees, makes them very 

 conspicvuous. The bark on the old parts is very thick and deeply cracked ; 

 the branchJets generally dichotomous, and marked wilh the scars of the 

 fallen leaves. The leaves while young hoary with soft pubescence ; the 

 Aouers few but large and white.
