Character of the Genus, Russelia. Calyx five-partedj 
segments acuminately subulate, nearly equal. Corolla hypogynous, 
tubular, ventricosely-wldening towards the summit, throat bearded, 
limb two-lipped, upper lip emarginately two-lobed, lower lip three- 
parted, segments nearly equal. Stamens four, inserted into the tube 
of the corolla, didynamous, included, dedexed; anthers two-celled, 
cells diverging. Ovary two-celled, the placentas inserted on each 
side of the dissepiment, bearing numerous ovules. Style simple ; 
stigma obtuse. Capsule subglobose, attenuately beaked, two-celled, 
splitting by a septicidal dehiscence into two valves ; valves bifid, the 
placentae at first cohering, ultimately free. Seeds numerous, very 
small, wfinged. 
Description of the Species, Russelia juncea. Stem about 
three feet high, angular, green, dividing into numerous very slender 
tetragonal branches of a pale green colour, the young ones nearly de¬ 
void of leaves, nodding. Leaves always small, often very minute, 
larger how^ever than the very slender branches, petiolate, ovate, acute, 
most delicately serrate or ciliate at the margin, sometimes furnished 
with one or two teeth. Inflorescence apparently panicled, but in
