100 TENTANDKIA— MONOGYNIA. [Lobelia. 



sepiments ; again each valve is deeply cleft ; so that on looking at the 

 upper lialf of an open capsule we find 4 or 6 valves or segments, each 

 having one of its sides introflexed, to form (wilh the introflexed side of 

 the neiglibouring segment) a dissepiment of a doable plate. Seeds fixed 

 to 2 or 3 lobes of a central, at length (when the valves open) free column 

 or receptacle, oval, pale brown, dotted. 



27. ViNCA. Lin?i. Periwinkle. 



1. V. minor, L. (lesser Periwinkle) ; stem procumbent, leaves 

 oLlongo-lanceolate their margins as well as the small lanceolate 

 teeth of the calyx glabrous. E. Bot. t. 917. 



Hedges and banks in woods ; decidedly wild in Devon, with blue and 

 white fl. Fl. May, June. 1^. — Wood of the shoots very tough ; not so 

 in the following species. 



2. Y.* major, L. (greater Peritvinhlc) ; stem suberect, leaves 

 ovato- cordate their margins as well as those of the elongated 

 subulate segments of the calyx ciliated. E. Bot. <. 514. 



Woods and thickets. Fl. May. I4 • — Twice the size of tlie former 

 in all its parts. Corolla mostly purple in both, but varying in intensity. 

 The anthers, stigma, -and fruit(x follicle) are highly curious in this genus. 



28. Samolus. Linfi. Brook-weed.

 obtuse, racemes many-flowered, pedicels with a small bractea. 

 E. Bot. I. 703. 



Marshy and watery places, especially in a gravelly soil. Fl. July. 

 11 — This plant is very generally dispersed throughout the world. Ste?tt 

 8 — 10 inches high, rounded, glabrous, as well as the ovate, subpetiolate, 

 entire, fleshy leaves. Flowers small, white. Cal. small, 5-cleft, per- 

 sistent ; the segments|crowning the rounded capsule. 



29. Jasione. Linn. Sheep's-bit.

Dry heathv pastures, in a light gravelly or heathy soil. Fl. June, 

 July. 0. — Stem Q — 10 inches high, branched. Flowers bright blue, 

 in terminal, dense, hemisphoerical heads, surrounded by a many-leaved 

 involucre. Cal. small, superior, 5-toothed. Cor. in 5 deep and narrow 

 segments. Anthers united at I he base. The whole inflorescence has, 

 indeed, a very near affinity with that of the Class Sjngenesia, where 

 Linnaeus placed it.
