AN ENCYCLOPADIA 
OF HORTICULTURE. 
DILLWYNIA (named in honour of Lewis Weston 
Dillwyn, a botanist whose labours were more especially 
directed to the British Conferve ; born 1778, died 1855). 
Orv. Leguminose. A genus of elegant greenhouse ever- 
green Heath-like shrubs. Flowers yellow or orange-red), 
few together, in axillary or terminal racemes or corymbs, 
rarely solitary; petals clawed. Leaves alternate or scat- 
- tered, simple, narrow-linear, or terete, channelled above; 
_ stipules wanting. There are about half-a-score species, 
al natives of Australia. For culture, see Chorizema. 
- D. ericifolia (Heath-leaved).* fl. yellow, in very short racemes . 
— er clusters, sometimes several together, almost sessile, in a 
terminal leafy corymb ; petals deciduous; calyx glabrous. May. 
l. numerous, rather slender, usually jin. to зіп. long, but sometimes | 
twisted when dry, obtuse, with a short, recurved or straight, 
but scarcely pungent, point. 1794. There are various forms of 
this plant, which bave been generally recognised as species; the 
· following are the most prominent: glaberrima (B. M. 944), parvi- 
Jolia (B. M. 1527), peduncularis, phylicoides, and tenuifolia. 
D. floribunda (bundle-üowered) Л. yellow, crowded, axillary, 
twin. April. l. crowded, subulate, mucronulate, scabrous from 
tubercles. A. 2ft. to 6ft. 1794. SYN. D. rudis. (B. M. 1545, 
under the name of D. ericifolia.) . 
glycinifolia (Glycine-leaved). А synonym of Chorizema 
_ angustifolium. \ 
D. hispida (hairy).* Л. disposed in terminal heads upon numerous

DIMIDIATE. Divided into two unequal parts. 
DIMORPHANTHUS (from dimorphos, two-formed ; 
allusion to there being two kinds of flowers, perfect and 
Пе). ORD. Araliaceew. This genus is now included 
der Aralia, and the species described below is in reality 
ely a variety of A. chinensis. A very handsome hardy 
rub, of erect habit, with very large, much-divided, spiny 
wes. This remarkably fine foliage plant requires a 
eltered, but sunny, spot, where it will fully develop its 
y. For sub-tropical gardening it is very useful, It 
os similar cultivation to Aralia (which see). 
DIMORPHANTHUS MANDSCHURICUS, showing Flowering 
detached portion of Inflorescence, and ms. Leaflet, 
. A state in which two forms of 
flower or leaf are produced by the same species. 
FIG. 669. DIONJEA MUSCIPULA (see page 478). —— 
DIMORPHOTHECA (from dimorphos, two-iorm: 
and theca, a receptacle; disk-florets of two forms). ORD. 
Composite. A genus of about twenty species of smo 
hairy, or glandular annual herbs or shrabby pere 
natives of South Africa. Flower-heads long-statke 
orange-yellow or purplish; ray the same colo" 
Leaves radical or alternate, entire, 1, í 
narrow. These half-hardy plants grow 
drained loam; they are suitable for opem 
during summer, and for cool greenhous in 
annual sorts should be sown 
spring, and planted out at the end of May. - 
nials are readily grown from cuttings. — —
