the edge of any part is lobed. ; : 
SIPHOCAMPYLOS (from siphon, a tube, and 
kampylos, curved; alluding to the form of the corolla). 
Syn. Lobelia (of Presl). ORD. Campanulacee. A large 
genus (nearly 100 species) of very beautiful, glabrous, 
hairy, or stellate-tomentose, stove or greenhouse herbs, 
sub-shrubs, or shrubs, sometimes climbing, natives of | 
tropical America. Flowers red, orange, or purplish, 
rarely greenish, usually large; calyx tube adnate, the 
limb of five leafy lobes; corolla straight or incurved, 
the lobes often incurved, equal or unequal, sometimes 
bilabiate, the lateral ones sometimes connate with the 
upper ones; staminal tube adnate to the base of the 
corolla; peduncles one-flowered, ebracteate or minutely 
bibracteolate, axillary or forming clustered corymbs or 
loose racemes at the tips of the branches. Leaves alter- 
nate, rarely whorled, entire or denticulate, rarely incised- 
toothed or pinnately lobed or dissected. The introduced 
species are described below. They succeed in a light, 
turfy loam, and peat, and are propagated by cuttings. | 
Except where otherwise indicated, they are herbaceous 
perennials.
