The treasury of botany: a popular dictionary of the vegetable kingdom; with which is incorporated a glossary of botanical terms . vmscipula. DION] l&fyz Ercatfurp of 23dtang. 410 DI01SLEA. A singular plant referred toin most works on structural and physio-logical botany, as affording a striking in-stance of vegetable irritability, B. musci-pula, Venuss Flytrap, the only species,belongs to the order Droseracece, and is anhumble marsh plant bearing from the root,on a smooth leafless stalk a few inches high,a corymb of white flowers. The root iscomposed of scales almost like a bulbwith a few fibres. From this proceed in aradiating manner a number of leaves onlougish stalks, which are winged like thoseof the orange-tree. The lamina of the leafitself is divided by the midrib into twonearly semicircular halves, each of whichis fringed with stiff hairs, and furnishednear the middle with three minute bristlesarranged in a triangle, which bristles areextremely irritable, and when touched bya fly or other insect cause the two sides ofthe leaf to collapse with a sudden spring,imprisoning the intruder until it is either.

Biomsa isderived from Dione, one of the C4reeknames of Venus : muscipula is in Latin afly-trap. As might be expected, the sameresult is produced by touching the irri-table bristles with any fine-pointed sub-stance, as a pin or bit of straw.

A genus of Prhnulacece,closely allied to Gregoria, and includingall the Oriental species previously de-scribed under the latter name, but dis-tinguished by Boissier from the EuropeanG. vitaliana on account of some slightdifferences in the seeds and in the shapeof the corolla. They are all small Alpinetufted plants, with flowers intermediatebetween
