100 BOTANY OF THE VOYAGE OF H.M.S. HERALD. 
A slirub from 4 to G feet high, branches dl- or trichotomous, roundish, smooth, articulated above the 
whoria of the leaves ; articulationa easily separable. Leaves three in a whorl, elongato-obovate, rounded at 
the apex, attenuated at the base ; upper surface light green, under surface somewhat glaucous, smooth on 
both sides, membranaceous, penninerved, 2-2^ inches long, 6-10 lines broad. Fetioles slender, 3-4 lines 
long, somewhat pubescent above, always glabrous beneath. 
The specimen before me is rather imperfect, and although I have no doubt it belongs to a new species, 
yet I am unable to say anything about the real structure of the flower ; I find only one involucrum, in 
which even the female apparatus is wholly wanting. This involucrum is slightly pubescent, of a cup-shaped 
form, divided into five obtuse lobes, on a pedicel 1 line in length, and measures about li line in diameter.

Volcano of Chiriqui, Veraguas. 
An erect, perhaps biennal plant, from 12 to 16 inches high, simple-branched. Brandies straight, 
slender, proceeding from below. Leaves distant, broad-linear, narrowed at both ends, and covered near the 
margin with very short stiff hairs, hirsute on the under surface, li-3 inches long, 1-3 hues broad ; upper 
ones frequently furnished below the middle with one or two large teeth. Petioles 4 lines long, covered 
with long articulated hairs. Inflorescence terminal, capitate. Involiicre campanulate, shortly pedicellated, 
smooth, obscurely four-toothed; teeth beautifuUy fringed. Style tripartite; stigmas shortly bifid. Fruit 
glabrous, consisting of three monospermous cocci. 
On comparing the descriptions by the above-mentioned authors with the figures given by Plukenet and 
Flumier, all referred by Linnaeus to his Euphorhia heterophylla, I find them difi'ering from each other so 
widely in every respect, that 1 am convinced that the descriptions of Brcynius and Morison refer to the 
plant collected by Berthold Seemann, while the figures published by Plukcuet and Plumier belong solely to 
the true EuphorUa Jieterophylla of Linnsus.
