 thrives in any ordinary soil, but, though hardy, it will 

 succeed best in a cool greenhouse. Propagation may be 

 effected by cuttings.

REINWARSTIA (of Dumortier) (named after 

 K. G. K. Reinwardt, 1773-1822, director of the Botanic 

 Garden at Leyden). Syn. Macrolinum. Ord. Linece. 

 A small genus (three species) of greenhouse or stove 

 shrubs or sub-shrubs, inhabiting the mountains of the 

 East Indies. Flowers yellow or white, rather large, in 

 very short, fascicle-like racemes, solitary in the axils, or 

 densely corymbose at the tips of the branches ; sepals 

 and petals five, the latter fugacious, twisted ; stamens 

 connate at base, hypogynous ; pedicels braeteate. Leaves 

 alternate, membranous, often serrate, penninerved. 

 R. tetragynum and R. frigijnuin, the only species calling 

 for mention here, are old, winter-flowering, warm green- 

 house plants, worthy of a more extensive cultivation 

 than they at present receive. Cuttings should bo taken 

 from the strongest points of old plants, and inserted, in 

 a close propagating frame, some time during April or 

 May. When rooted, they may be grown on singly, in an 

 intermediate temperature, until established, in .5in. or 

 Gin. pots. Pinching should be frequently practised, 

 when the plants are young, to induce a compact habit. 

 A position in frames, where plenty of air and sun can 

 be admitted, is best in autumn, as it is necessary to 

 thoroughly ripen the recently-made shoots for flowering 

 during the winter. A temperature of about 55deg. will 

 he necessary to open the flowers properly, and keep 

 them from damping-off. Old plants may be cut back, 

 and grown a second year under similar treatment ; but 

 they are not generally so strong or satisfactory as now 

 ones annually raised from good cuttings. Red Spider is 

 the most destructive insect to which the plants are 

 subject ; frequent and heavy syringings, applied through- 

 out the summer, will keep it in abeyance, and also 

 prove beneficial to the plants.

REIfHANIA (named in honour of the Rev. Richard 

 Relhan, who published, in 178.5, the "Flora Cantabri- 

 gensis"). Syn. Michau,ria (of Necker). Including 

 Eclopes. Ord. ComjMsitce. A genus comprising about 

 eighteen species of greenhouse shrubs or annual herbs, 

 natives of South Africa. Flower-heads yellow, mediocre 

 or rather large and solitary at the tips of the branches, 

 or smaller and solitary at the sides of the branches, or 

 in terminal corymbs; involucre oblong, ovoid, or rather 

 broadly campanulate, with many-seriate bracts ; recep- 

 tacle flat ; achenes linear, glabrous or ciliated on the 

 margins. Leaves alternate or rarely opposite, rigid, 

 narrow or small, channelled and concave above, keeled 

 or many-nerved at back. Several species have been in- 

 troduced, but are probably not now in cultivation. 

 R. pungens, the only one which calls for description 

 here, requires culture similar to that recommended for 

 Atlianasia (which see). 



R. pungens (prickly). Jl. -heads yellow, terminal, sessile, solitary, 

 uu)re than lin. in diameter ; ray florets numerous, reddish down 

 the middle of the back. September. I. acerose, rigid, sessile, 

 .ascending, scattered, rather wide-set, linear-subulate, about ^in. 

 long, entire, roughened by short, hard, inclined bristles on the 

 outside. Young branches grey-tomentose. 1820. A small, weak, 

 branching shrub. (B. R. 587.)

REMTTSATIA (named in honour of Abel Remusat, 

 1785-1832, a celebrated Orientalist and physician). Ord. 

 Aroidece (Aracew). A genus comprising three or four 

 species of stove, tuberous herbs, natives of the moun- 

 tainous regions of the sub-tropical East Indies and Java. 

 Flowers moncecious, on an inappendiculate spadix, which 

 is shorter than the spathe, sessile, and constricted in 

 the middle ; male and female flowers remote ; male in- 

 florescence cl.avate, stipitate, the female narrower and 

 sub-eylindrical ; spathe with a convolute, persistent, green 

 tube, a constricted throat, and a yellowish, spreading or 

 refracted, at length split and deciduous lamina ; peduncles 

 short. Leaves on long and slender stalks, peltate, ovate- 

 cordate, or lanceolate. Only one species is known to 

 cultivation. It requires culture similar to Caladiam 

 (which see). 



R. vivipara (viviparous). L netioled, peltate, cordate, entire, 

 4iii. to 12in. long, and 3in. to 8in. broad, acute, smooth on both

RENANTHERA (from ren, a kidney, and nnfhera, 

 an anther ; alluding to the reniform shape of the anthers 

 or pollen masses). Syn. Nephranthera. Ord. Orrliidecc. 

 A genus comprising about seven species of stove, epiphytal 

 orchids, natives of tropical Asia and the Malayan Archi- 

 pelago. Flowers showy or rather small ; sepals much 

 spreading, free, petaloid, the lateral ones broader and 

 often longer than the dorsal one, which latter the petals 

 resemble ; lip short, sessile at the base of the column, 

 articulated, saccate or spurred ; column short and thick ; 

 anthers terminal, convex ; pollen masses two, ovoid or 

 oblong ; peduncles lateral, elongated, branched ; racemes 

 loose, ample, panicled. Leaves distichous, spreading, 

 fleshy or rigid, often obliquely bilobed at apex. Stems 

 leafy, branched, not pseudo-bulbous. The best of the 

 species here mentioned are K. cocciiiea, R. Lnwii, and 

 R. Storiei ; the first recjuires warm-house treatment, and 

 should be fastened on a stump of Tree-fern or Ash, 

 against which it will grow to a great length, and flower
