thrives in any ordinary soil, but, though hardy, it will 
succeed best in a cool greenhouse. Propagation may be 
effected by cuttings.

REINWARDTIA (of Dumortier) (named after

Garden at Leyden). Syn. Macrolinum. ORD. Linee. 
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 bracteate. Leaves 
alternate, membranous, often serrate, penninerved. 
R. tetragynum and R. trigynum, 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 be 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 
6in. 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 
be 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 new 
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.

RELHANIA (named in honour of the Rev. Richard

Eclopes. ORD. Composite. 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

Aroidew (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 moneecious, on an inappendiculate spadix, which 
is shorter than the spathe, sessile, and constricted in 
the middle; male and female flowers remote; male in- 
florescence clavate, stipitate, the female narrower and 
sub-cylindrical ; 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 Caladium 
(which see). s

RENANTHERA (from ren, a kidney, and anthera, 
an anther; aliuding to the reniform shape of the anthers 
or pollen masses). Syn. Nephranthera. ORD. Orchidee. 
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 psendo-bulbous. The best of the 
species here mentioned are R. coccinea, R. Lowii, and 
R. Storie’; the first requires 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
