( Two-coloured Siphocamphylus.) 

 LINNEAN SYSTEM. NATURAL ORDER. 



PENTANDRIA MONOGYNIA. LOBELIACE^.' (Lindl.) 



GENERIC CHARACTER. 



Siphocampylus (Pohl). Calyx hemisphericus, 10-costatus, 5-dentatus. Corolla tubulosa, 

 bilabiata, apice reflexa ; labio superiore bipartite ; inferiore tripartite Filamenta monadelpha. 

 Anther ce coalitae, apice penicillatse. Stylus apice curvatus. Stigma bilobuni, papillosum. 

 Ovarium calyci adhaerens. Capsula bilocularis, apice dehiscens. Semina innumera. 



Calyx bemispberical, 10-ribbed, 5-toothed. Corolla tubular, two-lipped, reflexed at the top ; 

 upper lip 2-parted ; lower lip 3-parted. Filaments combined. Anthers joined, brush-like at the 

 apex. Style curved at the top. Stigma 2-lobed, papillose. Ovarium adhering to the calyx. 

 Capsule 2-celled, bursting at the apex. Seeds numerous. 



SPECIFIC CHARACTER. 



S. bicolor ; suffruticosus, glaber ; foliis ovato-lanceolatis, acutis, irregulariter serratis ; floribus 

 axillaribus, solitariis ; pedunculis hirsutis, bibracteolatis corollis longioribus. 



SufFruticose, smooth ; leaves ovate-lanceolate, acute, irregularly serrated ; flowers axillary, 

 solitary, peduncles hairy, with two bracts longer than the corolla. 



Siphocampylus bicolor. — Sweet's Flor. Garden, t. 389. 



Descb. — Stem round, smooth, six feet or more high, branched, having an unpleasant smell. 

 Leaves alternate, petiolate, ovate-lanceolate, acuminate, smooth, irregularly toothed, and giving 

 forth a milky juice when plucked from the stem. Flowers solitary, axillary, longly pedunculate. 

 Peduncles slender, covered with close adpressed hairs, having two small bracts near the centre. 

 Calyx covered with short hairs, 10-ribbed, and divided into five subulate teeth, which are ciliate. 

 Corolla tubular, pubescent, about an inch long, 2-lipped ; lips reflexed, the upper Up divided into 

 two portions, the lower lip into three portions; the tube is entire before the flower fully 

 expands, and afterwards is divided along the upper part, through which the organs protrude. 

 Its colour is an orange red, tipped with yellow. Filaments combined. Anthers combined of a 

 brownish yellow colour, crowned at the apex with tufts of white hairs. Style bent at the upper 

 part, and hairy immediately below the stigma. Stigma 2-lobed, papillose. Capsule 2-celled. 

 Seeds numerous. 



This genus was made as distinct from Lobelia by Pohl, in Sc. Plan. Brazil. ; 

 whether it will remain so we have much doubt. We see very little to cause the 

 separation, upon comparing the structure of each.
