THE DICTIONARY OF GARDENING, 
Zischynomene—continued. : 
ORD. Leguminose. Stove herbs and shrubs, with impari- 
pinnate leaves, having many pairs of leaflets, and axillary 
racemes of usually yellow flowers. They thrive well 
in a good rich loam. Propagated by cuttings, placed in sand 
under a bell glass, in a brisk heat. Seeds of the herbaceous 
‘species require a good heat to start them into growth. The 
annuals are not worth growing. There are about forty other 
species known besides those mentioned, some of which may 
prove worthy of cultivation when introduced into this 
country. 
Æ. (rough-stemmed), fl. yellow; racemes compound ; 
peduncles, bracteas, calyces, and corollas, hispid. June. l. with 
thirty to forty pairs of linear leaflets, which are smooth as well as 
the legumes. Stem herbaceous, perennial, erect. h. 6ft. to 8ft. 
East Indies, 1759. 
Æ. sensitiva (sensitive).* f. white; legumes and racemes 
glabrous; peduncles branched, few-flowered. June. 1, with 
sixteen to twenty p= of linear leaflets. h. 3ft. to 6ft. Stem 
shrubby, smooth. Jamaica, 1733. This species requires a sandy 
soil. Shrub. 
ÆSCULUS (a name given by Pliny to a kind of oak 
having an edible fruit; derived from esca, nourish- 
ment). The Horse Chestnut. ORD. Sapindacee. A genus 
of hardy showy trees, well adapted for lawns or parks, 
having a beautiful appearance when in flower. They will 
do well in any soil, but.the more loamy the better. In- 
creased by layers, put down in the spring, or by grafting or 
budding on the common horse chestnut. Seeds, where pro- 
curable, should be sown singly in rows in spring, where they 
may remain until they are of sufficient size to be perma- 
nently planted out, This genus is distinguished from Pavia, 
in having its capsules echinated, i.e., covered with prickles, 
like a hedgehog; but this character is not always con- 
_ sistent. 
po carnea (fiesh-coloured). Synonymous with Æ. rubicunda.

Æ. Hippdcastanum (Common Horse-Chestnut). fl. white, tinged 
handsome terminal racemes, which are pro- 
only. 
Æ. ohioensis (Ohio). A synonym of A. glabra. 
Æ. pallida (pale-flowered). A synonym of A. glabra. 
Æ. rubicunda (red-flowered).* fl. scarlet, in very fine terminal 
_ Yacemes; petals four, having the claws shorter than the calyx ; 
_ stamens eight. June. lZ. with five to seven obovately-cuneated, 
acute, unequally serrated leaflets. A. 20ft. North America, 
1820. This is a very distinct and beautiful tree when in flower, 
er greeting attain so large a size as Æ. Hippocastanum. SYN. 
| ÆSTIVATION. Ths manner of the folding of the 
calyx and corolla in the flower bud. 
ZETHIONEMA (from aitho, to scorch, and nema, a 
filament; apparently in allusion to some tawny or burnt 
appearance in the stamens). ORD. Crucifere. A genus 
of elegant little plants, distinguished from allied genera in 
having the four larger stamens winged, and with a tooth. 
Herbs or sub-shrubs, perennial or annual, branched from 
the base, diffuse or erect. Flowers in crowded terminal 
racemes. Leaves fleshy, sessile. They are well worth culti- 
vating in sunny situations, where they form a freer flower- 
ing habit than when growing in a wild state. Some of the 
_ more hardy species may be planted on rock work, which, by 
_ their dwarf growth, they are well adapted for. The annual 
and biennial species may either be sown on rockwork or in 
_ the front of the flower-border. A light dry soil suits them 
- best. The shrubby kinds of this genus should be kept in 
pots, which should be well drained with potsherds, and 
: -~ in May; or by cuttings, planted in summer.
