THE DICTIONARY OF GARDENING, 
RAVENTIA (no explanation given by author). Includ- 
ing Lemonia. ORD. Rutacew. 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; 
stamens 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). fl. rose-red, axillary, 24in. to 3in. in 
diameter. Summer. l. trifoliolate; leaflets elliptic-obovate, 
entire, shining. h. 2ft. Brazil, 1880. 
R, ctabilis (showy). fl. deep reddish-scarlet, showy; 
corolla fleshy, rugulose, hypocrateriform, the segments obtuse ; 
racemes axillary, few-flowered, nearly equalling the leaves. July 
and August. J. trifoliolate ; leaflets longer than the pubescent 
— obovate, obtuse, glabrous. Branchlets pubescent. h. 2ft. 
ba, 1839. (B. R. xxvi. 59, under name of Lemonia spectabilis.)

REAUMURIA (named in honour of René A. Fer-

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 
Tamariz; 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).* 
ji. 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. J. coriaceous ; 
eauline ones linear, linear-lanceolate, 
lanceolate-oblong, or lanceolate. h. 2ft.

REAUMURIACEZ. Included 
under Tamariscinee. 
RECEPTACLE. “A portion of 
axis forming a common support or 
bed on which a cluster of organs is 
borne. The Receptacle of the flower, 
or the torus, is the axile portion of 
a blossom, that which bears sepals, 
petals, stamens, and pistils. The Re-

axis or rachis of the head, spike, 
or other dense cluster” (Asa Gray).
