THE DICTIONARY OF GARDENING, 



RAVENIA (no explanation given by author). Includ- 

 ing Lemonia. OED. Rutacece. A genus comprising only 

 a couple of species of highly glabrous, stove or warm 

 greenhouse shrubs, with terete branchlets ; one is a 

 native of Cuba, and the other Brazilian. Flowers white 

 or scarlet, few, on axillary, elongated peduncles; sepals 

 unequal, imbricated, the two outer ones larger; corolla 

 tube straight; limb sub-oblique, of five oblong lobes; 

 etamens five, adnate to the throat of the corolla. Leaves 

 opposite, one to three-leafleted ; leaflets sub-coriaceous, 

 lanceolate, entire, slightly dotted. The species are 

 beautiful shrubs, thriving in sandy peat and fibry loam. 

 Propagated by cuttings of half-ripened shoots, inserted 

 in sand, under a bell glass, in bottom heat. 

 R. rosea (rose-coloured). /. rose-red, axillary, 2Jin. to Sin. in 



diameter. Summer. 1. trifoliolate ; leaflets elliptic-obovate, 



entire, shining, h. 2ft. Brazil, 1880. 

 R. spectabilis (showy), fl. deep reddish-scarlet, showy; 



corolla fleshy, rugulose, hypocrateriform, the segments obtuse ; 



racemes axillary, few-flowered, nearly equalling the leaves. July 



and August. L trifoliolate ; leaflets longer than the pubescent 



petiole, obovate, obtuse, glabrous. Branchlets pubescent, h, 2ft. 



Cuba, 1839. (B. K. xxvi. 59, under name of Lemonia spectabilis.)

REAUMURIA (named in honour of Bend A. Fer- 

 chault de Beaumur, 1683-1757, a famous French ento- 

 mologist). OED. Tamariscineae. A genus comprising 

 about half-a-score species of half-hardy, much-branched, 

 procumbent or divaricate sub-shrubs or small shrubs, 

 natives of the Mediterranean region (mostly Eastern) and 

 central Asia. Flowers terminal, solitary, larger than in 

 Tamarix ; sepals five, sub-connate or nearly free at base, 

 surrounded by few or many imbricated, sepaloid bracts ; 

 claws of the petals broad; stamens many. Leaves small 

 or fleshy, sub-terete, often clustered. R. hypericoides, the 

 species best known to gardeners, is a beautiful shrub, 

 of easy culture; a compost of sandy loam and peat is 

 most suitable. It may be readily increased by means of 

 cuttings taken from the young wood, 

 and inserted in similar soil, under a 

 bell glass. 



R. hypericoides (St. John's Wort-like).* 

 JL purple; petals irregular, ovate or 

 ovate-oblong, very obtuse, the appendices 

 short and slightly fimbriated at apex ; 

 bracts lanceolate-subulate, a little longer 

 than the calyx. August. I. coriaceous ; 

 cauline ones linear, linear-lanceolate, 

 lanceolate-oblong, or lanceolate, h. 2ft. 

 Syria, 1800. (B. M. 2057 ; B. R. 845.)

RECEPTACLE. "A portion of 

 axis forming a common support or 

 bed on which a cluster of organs is 

 borne. The Eeceptacle of the flower, 

 or the torus, is the axile portion of 

 a blossom, that which bears sepals, 

 petals, stamens, and pistils. The Re- 

 ceptacle of an inflorescence is the 

 axis or rachis of the head, spike, 

 or other dense cluster" (Asa Gray).
