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. he. 

 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; lloribus geminis aut temis, 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 pointed 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 Isete viridibus, subtus in rachin pilosis, geminis, aitero multo 

 minore; floribus plurimis, fasciculatis, congestis, extra-axilla- 

 ribus, petiolum subsequantibus ; coroUse tubo calyce duplo lon- 

 giore, infundibuliformi, limbo 5-partito; bacca sphserica. — 

 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, 2i to 3^ inches broad, upon petioles 5 to 8 lines' 

 long, caniculate and hispid ; the smaller leaves in each pair are 

 only 1| 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 harharum. The calyx is urceolate, obsoletely 

 5-tgothed, 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.
