APOCYNUM. 



nivent, oblong arrow-shaped anthers, cohering with the stigma about 

 their middle, and often holding fast such insects as may thrust their 

 proboscis between them. The nectary consists of 5 oblong glandular 

 bodies, alternating with the stamens. Ovaries 2, ovate, concealed by 

 the anthers. Stigma thick, roundish, agglutinated to the anthers. 

 The fruit is a pair of slender linear-lanceolate follicles, containing 

 numerous imbricated seeds, each crowned with a long pappus or down, 

 and attached to a slender central receptacle. Every part lactescent. 

 Root with an unpleasant intensely bitter taste ; acts as an emetic when 

 recent. In small doses is a useful tonic.

 diuretic and diaphoretic.

 flowered. Corolla hypocrateriform, white, very sweet-scented, with a 

 slender tube J of an inch long; limb spreading, flat, about the same

 The bark is called Ccnessi in commerce, and has been introduced into 

 European practice on account of its astringent febrifugal qualities.

 the throat without appendages. Stamens enclosed ; anthers 

 sagittate, with the posterior lobes empty of pollen. Scales 5, 

 hypogynous, filiform. Ovaries 2 ; style 1, filiform ; stigma ovate,

Stems woody, smooth. Leaves short-stalked, oblong, acute, broad, 

 smooth, veiny, dark green above, paler beneath. Peduncles axillary, 

 long; pedicels shorter, fasciculate. Flowers small, tubular, 5-cleft, 

 purple. Calyxes 5-cleft, oblong. Sometimes used in India as a sub- 

 stitute for Sarsaparilla, according; to Professor Royle. It appears from 

 a quotation in R. and S. that it is also mentioned as a medicinal plant 

 by Afzelius, in his Remedia guineensia, a work to which I have not 

 access.
