Many are valuable on account of their fruits, e.g. Cucurbita, 
Sechium, Luffa, Lagenaria, &c. 
Classification and chief genera (after Pax) : 
A. Pollen-sacs not fused into a ring. 
a. Sta. free or only united at base. 
I. Fevilleeae (sta. 5, rarely 4) : Fevillea, Zanonia, Thladiantha. 
II. Melothrieae (sta. 3, rarely 2 or 4; pollen-sacs straight or 
slightly curved): Melothria, Telfairia. 
III. Cucurbiteae (do., but pollen-sacs S or U shaped): Acan- 
thosicyos, Momordica, Luffa, Bryonia, Ecballium, Cucumis, 
Lagenaria, Trichosanthes, Cucurbita. 
b. Sta. united into a column. 
IV. Sicyoideae: Echinocystis, Sechium, Sicyos. 
B. Pollen-sacs fused into a ring. 
V. Cyclanthereae: Cyclanthera (only genus). 
Culcitium Humb. et Bonpl. Compositae (vm). 14 sp. Andes. Like 
Espeletia (q. v.). 
Cullenia Wight. Bombacaceae. 1 sp. India, Ceylon. 
Cuminum (Toum.) Linn. Umbelliferae (7). 1 sp., C. Cyminuin L., 
Medit. The fruits are known as Cumin seeds, and are sometimes 
used like Caraway seeds. 
Cunninghamia R. Br. Coniferae (Arauc. 1 c; see C. for genus charac- 
ters). C. sinensis R. Br. the only sp., in S. China and Cochin-China. 
Cunonia Linn. Cunoniaceae. 5 sp. New Caled., and C. capensis L. 
S. Afr. It shows good bud-protection by stipules (p. 155). 
Cunoniaceae. Dicotyledons (Archichl. Rosales). 21 gen. with 120 sp., 
chiefly found between 13 0 and 35°S. Shrubs and trees with opp. or 
whorled leathery leaves, stipulate (the stipules often united in pairs as 
in Rubiaceae). Fir. small, usually $ . Receptacle usually flat. K 
4 — 5; C 4 — 5, usually smaller than calyx, often absent; A 8 — 10 or 
00 or 4 — 5; G usually (2), rarely 2. Ovary usually 2-loc., generally 
with 00 — 2 ovules in 2 rows in each loc. Fruit usually a capsule, 
rarely drupe or nut. Endosperm. Chief genera: Cunonia, Wein- 
mannia. United to Saxifragaceae by Benth.-Hooker; placed in 
Saxifraginae by Warming. 
Cupania Linn. Sapindaceae (1). 32 sp. trop. and subtrop. Am. The 
wood of some sp. is useful. For C. sapida Voigt (= C. editlis Schum. 
et Thonn.) see Blighia. 
Cuphea P. Br. Lythraceae. 160 sp. Am. The leaves are decussate 
and in most sp. there is one flr. at each node, standing between the 
two leaves. This is really the axillary flr. of the leaf below, and its 
peduncle is ‘adnate’ to the main stem. Many sp. are covered with 
exceedingly sticky glandular hairs. 
Cupressaceae (Warming) =Araucariaceae § Cupressineae. 
Cupressus Tourn. ex Linn. [Synonymy: C.fastigiaiaY>C. — C. semper- 
virens L. ; C. pendula Staunt.= C. funebris Endl. ; C. nootkatensis
