1900 SUPPLEMENT—RECENT INTRODUCTIONS, &C. 649 
Roydsia—continued. 
pedicels bibracteate at base. Fruit red, olive-shaped. 
Leaves ample, shortly petiolate, simple, oblong, exsti- 
pulate. R. swaveolens, the only species introduced, is a 
rather coarse, rambling bush, well worth cultivating for 
its delicions fragrance by those who can give it space 
enough: it is not suited for small houses. The plant 
thrives in good, rich, loamy soil, and may be readily 
increased by cuttings of the young wood. 
R. suaveolens (sweet-scented). . numerous, jin. in diameter, 
fragrant; stamens about 100, spreading; racemes axillary, or 
rather above the axils, 3in. to 7in. long, solitary or in terminal 
anicles. January to May. jr. lin. to lsin long. J. alternate, 
in. to 12in. long, oblong or oblong-lanceolate, rarely oblanceo- 
late, acute or acuminate, entire, shining, pale beneath; petioles 
sin. to sin. long. East Indies. (B. M. bl.) 
RUBENTIA. Included under Eleodendron (which 
see). 
Fic. 660, RUBUS PHGNICOLASIUS. 
_RUBUS. To the species, &c., described on pp. 331-2, 
Vol. III., the following should be added : 
R. americanus (American). A garden synonym of R. villosus. 
R. coronarius (crowned). A variety of R. rosefolius. 
R. deliciosus. The flowers of this species are snow-white, 
not red. 
R. fruticosus. Of this species there are several beautiful 
double-flowered varieties, both white and pink. 
R. f. czsius turkestanicus (Turkestan). 7. 
and very narrow petals. fr. elongated, of 
Turkestan, 1892. (R. G. 1892, p. 106, f. 25.) 
R. japonicus tricolor (Japanese, three-coloured). /. Simple, 
three-lobed, toothed; young ones pink; older ones variegated 
with white; petioles (and stems) rose-coloured. Japan, 1894. 
(G. C. 1894, xvi., p. 96, f. 15.) 
R. lasiostylus (woolly-styled). j., petals blood-red, orbicular- 
spathulate, about half as long as the recurved sepals ; pedicels 
red; corymbs few-flowered, sub-terminal; style woolly. June. 
i. pinnate, 3in. to Sin. long; leaflets three to five, doubly 
serrated, white-tomentose beneath, the young ones suffused 
with red. Shoots 4ft. high, erect, sin. thick; prickles slightly 
curved. China, 1889. (B. M. 7426.) a hi 
R. leucodermis (white-skinned).* . white; peduncles axillary 
and terminal, few-flowered. /r. pale pink, large, with a whitish 
bloom. J. trifoliolate or sometimes pedately five-foliolate ; 
leaflets broadly ovate, incised-serrated, acute, canescently 
tomentose beneath. Stems glaucous, armed with strong, 
recurved prickles. Oregon and California. A pretty species. 
R. melanolasius (dark-woolly). This is described as a species 
eiolar to the Raspberry (2. Ideus). North-west America, 
R. Millspaughi (Millspaugh’s). ‘A spineless Bramble, with 
edible fruits.” North America, 1892. 
R. moluccanus (Moluccan). The correct name of R. re/lexus. 
R. paucifiorus (few-flowered). A form of R. lasiocarpus. 
R. phoenicolasius. Japanese Wineberry. The scarlet fruits 
of this variety are not only ornamental but very useful for 
culinary purposes. They are not sweet enough for dessert, 
but make excellent jam, and they come in just after Raspberries 
are over. The plamt does best in a dry, sunny position. See 
Fig. 660.

RUDBECKIA. Echinacea (which see) and 
Lepachys were formerly included under this genus, but

R. pallida is synonymous with Echinacea angustifolia. 
R. pinnata. The correct name is Lepachys pinnatijida. 
R. purpurea. The correct name is Echinacea purpurea. 
R. subtomentosa (slightly tomentose). jl.-heads showing 
hardly any raised disk; ray florets golden, numerous, lin. to 
ljin. long; disk black. Early and late summer. J/. nearly all 
petiolate, ovate, acutely serrated, or the terminal lobe ovate 
and the lateral ones oblong or lanceolate. h. 2ft. to Oft. 
Plant cinereous with soft pubescence. 
Varieties. There are two especially good varieties in 
Autumn Glory, with golden-yellow flower-heads and bronzy 
disk ; and Golden Glow, a beautiful double-flowered variety 
of R. laciniata. 
RUDGEA. To the species described 
Vol. III., the following should be added : 
R. nivosa (snowy). jl. snow-white, few, imperfectly cymose ;
