RICHARDIA. The old method of growing Richardia 
africana—namely, of drying them off in summer and 
starting them again in autumn—is gradually falling into 
desuetude. In fact, it has been abundantly demonstrated 
that this species may be made to furnish its spathes 
continnously. By this system, when making new growth, 
the plants are kept in the beds or borders; or again, they 
may be potted up and left outside until they have recovered 
from the slight check received and become established. 
In the dull months of the year and in spring they shonld 
be kept fairly cool, well watered, and from time to time 
given a suitable stimulant. R. Hlliottiana and R. angus- 
tiloba (Pentlandii) should be grown in the warm pit daring 
winter, and in the cool one during summer. 
To the species described on p. 307, Vol. III., the following 
should be added : 
A synonym of 
A hybrid between R. divari- 
Fia. 651. 
RICHARDIA ELLIOTTIANA. 
R. africana. A curious form of this species with a branched 
spadix is figured in G. C. 1895, xvii., p. 135, f. 19, 20. nana 
compacta is a compact form, less than half the height of the 
type, but with flowers almost as large. 
R. albo-maculata sulphurea (sulphur-coloured).* A variety 
having a soft-yellow spathe with black centre, and elegantly 
spotted foliage. 
R. angustiloba (narrow-lobed).* ., spathe 4in. to 44in. long, 
the limb clear deep gamboge-yellow, with a dark purple-brown 
blotch at the base inside, paler outside, oblique, nearly 
horizontal; spadix scarcely half as long. 2 74in. to 17in. long, 
4in. to llin. broad, elongate-deltoid or -oblong, acute or 
acuminate, hastate, with short or long and spreading basal 
lobes and a very open sinus. 1892. Syn. R. Pentlandii 
Richardia—continued. 
(B. M. 7397), under which name it is generally catalogued by 
the trade and it is grown at Kew. 
R. aurata (golden). A synonym of R. hastata. 
R. Elliottiana (Capt. Elliott’s).* ., spathe bright golden- 
yellow, 6in. long, the tube between funnel-shaped and cam- 
panulate, the limb 3in. long and broad, with a caudate tip; 
spadix orange-yellow, about 3in. long; peduncle nearly Sit. 
high. August. U2. nearly lft. long, 7in. broad, orbicular- 
ovate, deeply cordate, apiculate, with transparent blotches (see 
Fig. 651); petioles as long as the leaves. 1896, (B. M. 7577.) 
R. Lehmanni. A misprint for R. Rehmanni. 
R. Lutwychei (Lutwyche’s). Pride of the Congo. 
of R. hastata. 
R. Pentlandii (Pentland’s). A synonym of R. angustiloba. 
R. Rehmanni (Rehmann’s). /., spathe 3in. to 44in. long, the 
limb bright rosy-purple, darker at the base within but not 
blotched, or white or greenish-white to the base within, with 
rosy-tinted margins ; spadix not half as long. J. 7jin. to 15in. 
long, lin. to 2in. broad, lanceolate, subulate at apex, green or 
white-spotted. 1893. (B. M. 7436; G. C. 1893, xiv., p. 564, f. 94, 
as R. Lehmanni [by error].) 
R. Rhodesia (Rhodesian). /. having a very large spathe of a 
rich, dark golden hue. 1898. 
R. suffusa (suffused).* This appears to be merely a robust form 
of R. melanoleuca. 1899. 
RICHARDSONIA PILOSA. This is the correct 
name of the plant referred to in Vol. III. as R. scabra. 
RICINELLA. A synonym of Adelia (which see). 
RICINUS. To the species described on p. 308, 
Vol. III., the following varieties should be added. Fatsia 
japonica (Aralia Sieboldii) is, in London, often sold as the 
Castor Oil Plant (R. communis) to the uninitiated. The 
fruits of these are curious in autumn. 
R. cambodgensis (Cambodia).* This is a handsome form of 
R. communis, with large purple leaves and blackish stems and 
branches. 
R. communis borbonensis arboreus (Tree-like).* The 
foliage is bronzy-green, and the plant grows to a height of 5ft. 
A capital subject for lawns. 
R. c. cinerascens (zreyish). 
purple, becoming deeper. 
R. c. enormis (enormous). /. large, brownish-purple, changing 
to dark green or red when older. 
R. c. Gibsonii atrosanguineus (dark-red). 
crimson-red leaves, and growing some 4ft. or Sft. 
R. c. maculatus (spotted). A variety with coppery-bronze 
foliage and red veinings thereto. 
R. c. zanzibarensis (Zanzibar).* /. bright green, with whitish 
veins, handsome, 2ft. across. jr. having the seeds much larger 
than, and different in shape from, those of the typical 
R. communis. _h. 6ft. to 8ft. Eastern tropical Africa, 1894. 
(R. G. 1894, p. 75, £. 20.) 
RIDAN. A synonym of Actinomeris (which see). 
RIDDLING. This consists in Riddling soil through 
a fine sieve for sowing yery fine seeds on, putting in 
cuttings, &e. -It is also employed for the removal of 
objectionable substances—such as_ broken pieces of pots, 
&c.—from soils which it is intended to usefully employ. 
RIGIDELLA. According to J. G. Baker, R. orthantha 
(F. d. S. 46) is apparently a mere form of R. flammea 
with shorter, stouter, erect pedicels. 
RIPENING WOOD. A very important detail in 
the production of fine frnit and flowers is the proper 
Ripening of Wood. This may be effected by the removal 
of all useless wood in August, thus exposing what is left 
to the full action of sun and air. Again, in trained 
plants and trees the wood must not be congested, or it 
will not properly mature, and the results the following 
year will be unsatisfactory.

RITCHIEA. To the species described on p. 309, 
Vol. III., the following, which is now regarded as a 
distinct species, should be added:

across, three to five in terminal, erect corymbs; petals about 
fourteen, very narrow.
