GERANIUM. To the species and varieties described

GERRARDANTHUS (called after W. T. Gerrard, 
a collector at Natal). Orv. Cucurbitacee. A small 
genus (three species) of stove or greenhouse, tall, gla- 
brous climbers, natives of Western and Eastern tropical 
Africa. Flowers greenish or fuscons, dicecious ; ealyx five- 
lobed; corolla rotate or campanulate, deeply five-parted; 
males racemose, with four stamens and an imperfect fifth ; 
Gerrardanthus—continued. 
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 jin. 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 yin. thick. . . . The natives do not appear to 
put the plant to any use”’ (‘‘ Botanical Magazine,” 6694). 
The plant may be increased by seeds. 
G. tomentosus (downy). i. yellow, din. in diameter, the males 
in short racemes, the females one or two together. //. 3in. long, 
obovoid, ten-ribbed, dry, opening by three lobes. J. large, cordate- 
reniform, five-lobed. (B. M. 6694.)

pinnate; side pinne with coarse, deep serrations; terminal 
leaflet large, heart-shaped, lobed. Stems numerous, 6in. to 8in.

interesting natural hybrid between G. montanwim and (G. reptans, 
discovered on the south side of Monte Rosa, 1886. (R. G. 1229.) 
Syn. Sleversia rhetica.
