called the hill fever. I conceive every part of this plant to 

 be possessed of strong, stimulating powers, and have no

BUTTNERA. Sckreb. gen. N. 366. 

 Calyx five-leaved. Corol five-petalled. Nectary stami-

1. B. pilosa. R. 



Shrubby, twining, hairy. Leaves from three to five, acute- 

 angled, dentate. Umbels axillary, proliferous. 



A most extensive, twining shrub; a native of Chittagong. 

 The flowering time in the Botanic garden at Calcutta is Sep-

Stem woody, twining, in five years old plants as thick as a 

 man's wrist, and irregularly obtuse-sulcate. Branches nu- 

 merous, twining up and over large trees, to a very great ex-

 acute angles, dentate, posterior lobes large and rounded ; 

 about seven-nerved, with a large, long gland on the middle 

 one near the base, from four to six inches each way. Peti- 

 oles round, often as long as the leaves, hairy. Stipules subu- 

 late, hairy. Umbels axillary, generally one large, and super- 

 decompound ; and two or more smaller, all are clothed with 

 short, harsh pubescence, and are much shorter than the leaves. 

 Bractes subulate. Flowers numerous, small. Calyx of five, 

 spreading, pale-coloured, lanceolate leaflets. Petals five; 

 the lower third part of their length linear, yellow on the out- 

 side, and red within ; much incurved so as to form a circular 

 dome over the pistil and nectary, open at the five sides, and
