_ Leguminose. A handsome genus of hardy deciduous shrubs 
with very graceful impari-pinnate leaves, and many pairs of 
leaflets, which are full of pellucid dots. Racemes spicate, 
elongated, usually in fascicles at the tops of the branches; 
corolla without wings and keel; vexillum or standard 
ovate, concave. They are well adapted for small shrub- 
. beries, requiring a sheltered situation, and thrive well 
in common garden soil. Increased by layers, or cuttings, 
taken off at a joint, and planted in a sheltered situa- 
tion early in autumn; these should be allowed to remain 
undisturbed till the following autumn. Amorphas produce 
an abundance of suckers, from which they may be readily 
propagated. :

AMORPHOPHALLUS (from amorphos, deformed, 
and phallos, a mace; alluding to the inflorescence). ORD. 
Aroidew. A very remarkable genus, closely allied to Arum, , 
but distinguished therefrom by “their spreading not con- 
volute spathes; by their anthers opening by pores, not by 
longitudinal slits; by the numerous cells to the ovary, and 
by the solitary erect ovules, those of Arum being horizontal.” 
A soil consisting of two-thirds good rich loam, with the 
additional third of sweet manure, thoroughly rotted, suits 
them well. Other essentials are plenty of pot room, a genial 
atmosphere, and a temperature eet EN 55deg. to 
65deg., or even 70deg. They require to be ept dry, and 
warm in winter, as nothing is more fatal to them than cold 
or damp. Beneath a shelf or stage in the stove is an 
excellent spot for them, or they may be stored in sand, 
and kept free from frost. They are difficult to increase ; 
the corms of most of them are of great size, and rarely make 
offsets. 
plants to seed whenever practicable, otherwise the rate of 
increase will be slow. All the species are strikingly effec- 
tive in sub-tropical bedding. For fertilising and growth 
of seedlings, see Arum.

deciduous shrubs, of very -easy culture in common garden 
soil. Cuttings, having a good eye, may be taken in Sep- 
tember, and pricked either under handlights in sandy soil 
on the open border, or in pots stood on the stage or shelf in 
a greenhouse; they root readily, and will be fit for trans-
