A rugosa (wrinkled). Synonymous with A. genevensis. 
= AKEBIA (its Japanese name). Syn. Rajania. ORD. 
_Lardizabalacee. A pretty twining shrub, succeeding well 
in the south-western counties of England, or in Scotland, 
trained to a trellis, or rambling over other shrubs in the 
open; but, when so grown, it requires the protection of a 
mat in winter. It makes an excellent twiner for the cool 
greenhouse. Sandy loam, leaf soil, and peat are most 
suitable for its culture. Increased by root divisions and” 
cuttings. 
A. quinata (five-leafletted).* fl. purplish brown, small, in axillary 
- racemes, very fragrant. March. J. on very slender petioles, and 
palmately divided into usually five distinct petiolulate oval or 
oblong emarginate leaflets, the bottom pair smallest. h. 10ft,

late; petals linear, spreadingly reflexed. They thrive well 
in a mixture of loam and peat, or any light rich soil. Cut- 
tings root readily if planted in a pot of sand, with a hand 
glass placed over them, in heat. 
A. decapetalum (ten-petaled).* fl. pale purple, with a grate- 
ful scent, solitary, or two to three together in the axils of the 
leaves ; petals ten or twelve. June, l alternate, oblong-lanceo,

ALBUCA (from albicans, or albus, white; the colour of 
the earlier species). ORD. Liliacee. A rather extensive 
genus of Cape of Good Hope bulbs, requiring ordinary 
greenhouse culture. Closely allied to Ornithogalum. 
Perianth six-cleft, three outer segments spreading; three 
inner ones closed over the stamens. They, however, suc- 
ceed admirably when grown in a warm sunny position 
out of doors, if covered with a hand glass, or litter, during 
winter. A light loamy soil, with leaf mould and sand, 
suits them well. Propagated by offsets from the old 
bulb, or seeds. There are but few species worthy of 
cultivation. .
