1900 SUPPLEMENT—RECENT INTRODUCTIONS, &c. 389 
GERBERA (named in honour of Gerber, a German 
naturalist, who travelled in Russia). ORD. Composite. 
A genus embracing about twenty species of greenhouse 
herbs, with a very short, perennial caudex, all African 
and Asiatic (temperate or mountainons regions). Flower- 
heads yellow, pink, or white, solitary, heterogamous and 
radiate, rarely homogamous and discoid; inyolucre tur- 
binate or broadly campannulate, the bracts in two or more 
series; receptacle flat; pappus copious; scape naked or 
sealy. Leaves radical, entire or sinuate-pinnatifid. The 
three species introduced thrive in a compost of sandy 
loam and peat. Propagation may be effected by seeds or 
by cuttings of the side shoots. In favoured localities and 
in dry, sunny borders, G. Jamesonii may be grown outside ; 
but in all other cases it is best treated as a greenhouse 
subject, still giving it a sunny but airy position. 
G. asplenifolia (Asplenium-leaved).* /jl.-heads Pareles pappus 
reddish ; scape cobwebby or woolly. 7. narrow, 4in. to 6in. long, 
petiolate, pinnatifid or pinnatisect, Fern-like, reddish-tomen- 
se beneath; lobes roundish, glossy above, concave, with 
revolute margins. South Africa. A handsome plant. 
G. crenata (crenate).* A synonym of Mairia crenata. 
G. Jamesoni (Jameson’s).* /l.-heads solitary, sub-erect, 3in. to 
4in. across ; ray florets bright orange or flame-coloured above, 
about thirty, in one series, ligulate ; scapes 10in. to 18in. long. 
Spring. JZ. Sin. to 10in. long, 2in. to 3in. broad, panansealy 
innatifid; petioles 6in. to 8in. long. Transvaal, 1888. See 
at aa M. 7087; G. C. 1889, v., f. 122; Gn. 1889, xxxvi.,

G. viridifolia (green-leaved). /l.-heads, rays white above, yellow 
beneath. J. shortly petiolate, elliptic or oblong, l4in. to 24in.

GERDARIA. A synonym of Sopubia (which see). 
GERM. Broadly, that portion of a plant which is 
capable of development into the likeness of that from 
which it sprang; literally, the embryo in a seed or 
spore. 
GERMAN CATCHFLY. Sce Lychnis Viscaria. 
GERMANEA. A Plectranthus

GERRARDANTHUS (called after W. T. Gerrard, 
a collector at Natal). Opp. Cucurbitacez. A small genus 
(three species) of stove or greenhouse, tall, glabrous 
climbers, natives of Western and Hastern tropical Africa. 
Flowers greenish or fuscous, dicecions; calyx five-lobed ; 
corolla rotate or campanulate, deeply five-parted; males 
racemose, with four stamens and an imperfect fifth ; 
females solitary, with an elevated, trigonal ovary. Fruit 
small, elongated, terete, many-seeded. Leaves mem- 
branous, cordate or hastate-cordate. G. tomentosus, the 
only species known to cultivation, is a stove perennial, 
of botanical interest. Mr. Wood, now Superintendent 
of the Natal Botanical Gardens, is recorded to have 
found, on the top of and between large stones, tubers, one 
of which ‘‘ measured 6ft. in circumference, and was nearly 
2ft. thick; its surface was scarred; and from the centre 
arose a stem not more than #in, in diameter, thickly 
covered with small, round. tubercles, which ascended 
without a leaf to the top of trees 50ft. high. On turning 
over one of the tubers, it was found to have but one fibrous 
root, about 4in. thick. . . . The natives do not appear to 
put the plant to any use”’ (‘‘ Botanical Magazine,”’ 6694). 
The plant may be increased by seeds.

in short racemes, the females one or two together. August. 
fr. 3in. long, oboyoid, ten-ribbed, dry, opening by three lobes.
