RALEIGHIA.- A Brazilian shrub, re- 

 sembling in habit some species of Wein- 

 mannia, having opposite undivided stipu- 

 late leaves, and small flowers in dense ter- 

 minal racemes. It forms a genus of Cimu- 

 niacece, nearly allied to Belangera, but dif- 

 fering chiefly in the one-celled ovary with 

 parietal placentas. 



RAMAL. Of or belonging to a branch. 



RAMALIXA. A small genus of lichens 

 with flat fronds like stag's horns, or nearly 

 cylindrical like Clavaria. The frond is alike 

 all round, without any distinct under-side, 

 in which the genus differs from Evernia. 

 R.fraxvaea grows everywhere on the trunks 

 of ash-trees, and R. farinacea, with its nar- 

 row mealy spotted fronds, is almost equally 

 common. Others are marine in their habits 

 like Roccellce. R. polymorpha and scopulo- 

 rum are good dye- weeds. [M. J. B.] 



EAMASTRA. The secondary petioles or 

 petiolules of compound leaves.

RAMEXTA. Thin membranous expan- 

 sions found upon the surface of plants, 

 and resembling hairs in composition, ex- 

 cept that they are not composed of a single 

 longitudinal series of cells, but of many 

 series of cells arranged on the same plane. 



EAMEXTACEOUS. Covered with ra- 

 menta, as the stems of many ferns. 



RAM-GOAT. Fagara microphijlla. 

 JRAMIPAROUS. Producing branches. 

 RAMONDIA. A genus of monopetalous 

 plants of doubtful aflBnity, and provision- 

 ally classed with Cyriandracece, from the 

 greater number of which it differs in hav- 

 ing five fertile stamens. It is a stemless 

 perennial herb, occupying rocks in the 

 Pyrenees, and also in the Piedmontese Alps. 

 ' The leaves are radical, ovate, and forming 

 rosettes, and the scape bears from one to 

 i six flowers of a purplish colour. The calyx 

 : is five-cleft ; the corolla rotate, and nearly 

 regular; the stamens are Ave, their fila- 

 ' ments short and glabrous ; whilst the style 

 I is simple; and the capsule oblong, one- 

 celled, enclosing numerous seeds. [B. S.] 



RAMOON-TREE. Trophis.

 stem. 



RAMUSCULI. The mycelium of certain 

 fungals. 



RANALES. An alliance proposed by 

 Lindley for the hypogynous polypetalous 

 families which have indefinite stamens 

 and a minute embryo enclosed in a large 

 quantity of fleshy or horny albumen. It 

 includes Magnoliacece, Anonacece, Dillenia- 

 cece, RanunculacecB, Sarraceniacece, and 

 Papaveracece. 



RANDIA. A genus of Cinclwnacece 

 I named in honour of Isaac Rand, formerly 

 ; Praefectus of the Botanic Garden of the 

 . Society of Apothecaries at Chelsea. The 

 I species are small trees or shrubs, natives 

 I of the tropical regions of both hemi- 

 j spheres. They have axillary spines, and, 

 so far as the construction of their flowers 

 ! goes.they are very nearly allied toGardenia. 

 The main differences are to be sought in 

 | the ovary, which is two-celled, and sur- 

 I mounted by a disk. The fruit has a dry 

 I rind, is surmounted by the limb of the ca- 

 lyx, and is internally divided into two 

 compartments, containing numerous seeds 

 imbedded in pulp. Moreover, the tube of 

 the corolla is usually shorter in this ge- 

 nus than in Gardenia. R. dumetorum is 

 used as a hedge-plant in India. Its fruit 

 is emetic, and is used to stupefy fish, so as 

 to allow of their ready capture ; the rind 

 of the root is also used medicinally. The 

 seeds of R. scandens furnish in China a 

 scarlet dye. The fruit of R. aculeata is 

 employed in the West Indies as a blue dye ; 

 its wood is used for cask-staves, ladders, 

 and other purposes. Some of the species 

 are in cultivation in this country as stove 

 shrubs; the flowers are whitish or yel- 

 lowish in colour. [M. T.M.J 



RANKNESS. A condition often as- 

 sumed by fruit-trees in gardens and or- 

 chards, in consequence of which great 

 shoots, or feeders as they are called, are 

 given out with little or no bearing wood.
