Mr. J. Miers on the genus Brachistus. 265 
glabrous, with a rotate 5-fid border, the segments being oblong, 
acute and hairy at the apex; the filaments are subulate, short 
and smooth. 
6. Brachistus dumetorum. Witheringia dumetorum, H. B. K. loc. 
cit. 16.—fruticosus, ramulis subangulatis, junioribus tomen- 
tosis; foliis ovatis, subacuminatis, basi cuneatis, supra hirto- 
pilosis, subtus hirto-tomentosis et canescentibus, superioribus 
geminis, aitero minore; floribus geminis aut ternis, extra- 
axillaribus, pedunculis filiformibus, tomentosis, petiolo multo 
longioribus ; corolla rotata, limbo 5-fido, laciniis brevibus, 
acutis, apice hirtis ; staminibus inclusis, glabris.—Nova Gra- 
nada. 
The leaves have a somewhat obtusely pomted acuminated apex, 
and are gradually contracted at base upon a short and caniculate 
tomentose petiole of 2 lines in length ; they are from 12 to 16 
lines long and 6 to 8 lines broad, somewhat coriaceous, with 
parallel nervures, which with the midrib are prominent beneath. 
The peduncles are 3 to 5 lines long, filiform and tomentose ; the 
flowers are the size of those of the preceding species, the calyx of 
which it also resembles in form ; the corolla is rotate, smooth and 
_ plicated ; the filaments are very short, subulate and smooth. 
7. Brachistus riparius. Witheringia riparia, H. B. K. loc. cit. 
16,—fruticosus, ramulis angulatis, hispido-pilosis ; foliis sub- 
oblique obovato-oblongis, acuminatis, basi acutis, supra glabris 
et leete viridibus, subtus in rachin pilosis, geminis, altero multo 
minore ; floribus plurimis, fasciculatis, congestis, extra-axilla- 
ribus, petiolum subzequantibus ; corolle tubo calyce duplo lon- 
giore, infundibuliformi, limbo 5-partito; bacca sphzrica.— 
Nova Granada (Andibus Quindiuensibus, alt. 6300 ped.). 
This species, from the greater length of its corolla, might be 
referred to Acnistus, did not the habit of the plant show it to 
be congeneric with the above-mentioned species described by 
Prof. Kunth. The larger of the geminate leaves are from 8 to 
10 inches long, 2} to 33 inches broad, upon petioles 5 to 8 lines 
long, caniculate and hispid; the smaller leaves in each pair are 
only 14 to 3 inches long, upon a much shorter petiole, and they 
are elliptic or ovate-elliptic, and acute at both ends. The flowers 
are fasciculated upon distinct peduncles, and are about the size of 
those of Lycium barbarum. ‘The calyx is urceolate, obsoletely 
5-toothed, thin and smooth; the corolla is of a greenish white 
colour, smooth, the border divided into five equal divisions; the 
filaments are pilose at base, the anthers oblong, bursting longi- 
tudinally ; the style is smooth and longer than the stamens.
