place for insects, and when they are ripe the style is bent down. 
Afterwards the sta. roll up and the style takes their place. C.fisiu- 
losum Becc. has hollow internodes inhabited by ants (see Cecropia 
and Myrmecodia). 
Clethra Gronov. Clethraceae. 25 sp. Canaries, N. Am., E. As. 
Clethraceae. Dicotyledons (Sympet. Ericales). An order composed 
of the single genus Clethra, often considered, e.g. by Benth. -Hooker, 
as an anomalous member of Ericaceae. Shrubs and trees with alter- 
nate leaves; firs, in racemes or panicles, without bracteoles, $ > regular. 
K 5, C 5 , polypetalous-, A 5 + 5, hypogynous; no disc . Anthers bent 
outwards in bud: pollen in single grains. Ovary 3-loc.; style with 3 
stigmas . Capsular fruit. Seed with endosperm. The characters 
given in italics are those in which C. differ from Ericaceae, and taken 
together fairly justify the separation. 
Clianthus Banks et Soland. {Donia Don.) Leguminosae (in. 6). 2 
sp. Austr., N. Z. Favourite greenhouse plants. 
Clidemia D. Don. Melastomaceae (1). 100 sp. trop. Am. 
Cliffortia Linn. Rosaceae (ill. 9). 40 sp. S. Afr. 
Clinopodium Linn. =Calamintha Tourn. 
Clintonia Dougl. = Downingia Torr. 
Clitoria Linn. Leguminosae (ill. 10). 30 sp. trop. and sub-trop. The 
firs, are inverted and the essential organs therefore touch the insect’s 
back, if it alight on the standard. 
Olivia Lindl. Amaryllidaceae (1). 3 sp. Cape Col. 
Clusia Linn. Guttiferae (iv). 80 sp. trop. and sub-trop. Am. They 
are mostly climbing epiphytes, clasping the host by anastomosing 
aerial roots, and frequently strangling it altogether (cf. Ficus Ben - 
jamina , &c.). The fleshy fruit is probably carried from tree to tree by 
birds. 
Clusiaceae (Warming) r= Guttiferae. 
Cluytia Linn. Euphorbiaceae (A. 11. 5). 28 sp. Afr. 
Clypeola Linn. Cruciferae (iv. 17). 12 sp. Medit. 
Cneoraceae. Dicotyledons (Archichl. Geraniales). Only genus Cneo- 
rum. Placed in Simarubaceae by Benth. -Hooker. Nearly allied to 
Zygophyllaceae, but separated because they have only one whorl of 
sta. with no ligules, and have no stipules, but possess oil-glands in 
the leaves. 
Cneorum Linn. Cneoraceae. 12 sp. Medit., Canaries. 
Cnestis Juss. Connaraceae. 9 sp. trop. Afr., As. 
Cnicus Linn, [inch Cirsium (Tourn.) Adans.]. Compositae (xi). 120 
sp. N. Hemisph. Several in Brit, (thistles). The genus is much con- 
fused with Carduus. 
Cobaea Cav. Polemoniaceae. 6 sp. trop. Am. C. scandens Cav. is a 
favourite greenhouse climber of very rapid growth. It climbs by aid 
of tendrils (leaf-structures) which are much branched, the branches 
ending in sharp hooks. The tendril nutates with great rapidity and
