leaf-opposed peduncles. Leaves alternate, petiolate. 
CG. intermedium (Syn. Ampherephis intermedia, 8. B. F. G. 
225) and C. punctatum (Syn. Ampherephis aristata) have 
been introduced, but are probably lost to cultivation. 
CENTRIFUGAL. A term applied to an inflorescence 
of which the terminal flower blossoms earliest. Opposed 
to a Centripetal one, in which the lower or outer flowers are 
the first to expand. 
CENTROCARPHA. Included under Rudbeckia 
(which see). 
CENTROCLINIUM. Included under Onoseris 
(which see). 
CENTROLEPIDEZ. A natural order embracing 
about thirty species of very small herbs, nearly all 
Australian, and allied to the Restiacex ; they are of botanical 
interest only. 
CENTRONIA. Syn. Calyptraria.” Flowers purple, 
large, disposed in large, terminal panicles ; calyx furfuraceous 
or hairy ; petals five to seven; stamens ten. Leaves ample, 
petiolate, entire or toothed.

Orchidex. A small genus (five or six species) of dwarf, 
creeping, cool-house Orchids, natives of the Colombian 
Andes. Flowers mediocre, solitary in the upper axils; 
sepals sub-equal, spreading, free, or the lateral ones more

towards the base with the column, at length erect, the 
lateral lobes scarcely prominent or broader and embracing 
the column, the lamina spreading, ovate or broadly 
rounded, undivided. Leaves distichous, short. C. punc- 
tatum (described on p. 421, Vol. II., as Nasonia punctata) 
is the best-known species. 
CENTROPOGON. This genus embraces upwards of 
eighty -species of shrubs or under-shrubs, natives of the 
warmer parts of America and the West Indies. Flowers 
solitary, axillary, pedunculate, rarely disposed in a ter- 
minal, elongated raceme; calyx lobes leaf-like or reduced 
to mere teeth; corolla curved, the tube entire or with a 
short dorsal cut, the limb incurved, with nearly equal 
lobes. Leaves alternate, toothed or rarely dissected. To 
the «pecies described on p. 293, Vol. I., the following

style, disposed in a terminalraceme. Winter. 7. ovate-lanceolate.

standard; the standard has a short spur behind). Orp. 
Leguminose. A genus embracing about twenty-six species 
of twining or prostrate, stove or greenhouse herbs or 
under-shrubs, mostly natives of Central or South America, 
and closely allied to Clitoria. Flowers white, violet, rose- 
coloured, or bluish, showy; standard broadly orbicular, 
with a short spur behind; wings falcate; keel broad, in- 
eurved, scarcely shorter than the wings; peduncles 
axillary, solitary or twin. Leaves pinnately three- to 
seven-foliolate, rarely one-foliolate or sub-digitately three- 
to five-foliolate. For culture of the few species introduced, 
see Clitoria.

CEPHAELIS. Syns. Callicocca, Carapichea, Cepha- 
leis, Eurhotia, Evea, Tapogomea. As many as seventy 
species are included hereunder. C. Bearii, introduced in 
1888, is a stove shrub, of no great beauty, with incon- 
spicuous umbels of flowers. 
CEPHALANDRA (from kephale, a head, and aner,

head). Syn. Coccinia. Orv. Cucurbitacee. A genus 
embracing twelve or fourteen species of stove or greenhouse,

usually dicecious ; males solitary or sub-cymose at the apex 
of a slender peduncle ; females solitary. Fruits cylindric or 
oblong, rather small, very fleshy. Leaves angled or lobed, 
sometimes glandular. Tendrils undivided. Two of the 
species have been introduced, but probably C. quinqueloba
