CHENOPODTA CEAE 
regular, small and inconspicuous, ? or unisexual ; their mode of ferti- 
lisation is not quite clearly understood. Perianth simple, rarely 
absent, persistent after flowering, of 5, 3, 2 (rarely 1 or 4) leaves, more 
or less united, imbricate, sepaloid. Sta. as many as or fewer than 
the perianth segments, opp. to them, hypogynous or on a disc ; 
anthers bent inwards in bud. Ovary superior (semi-inferior in Beta), 
i-loc. with 2 (rarely more) stigmas. Ovule 1, basal, campylotropous. 
Fruit usually a small round nut or achene. Embryo usually sur- 
rounding the endosperm, either simply bent or spirally twisted. Few 
of the order are useful plants ; see Beta, Spinacia, Chenopodium, &c. 
Classificatio?t and chief genera (after Volkens). The grouping 
depends on numerous characters and would occupy too much space ; 
the names of the tribes only are therefore given. 
A. C YCLOLOBEAE. Embryo ring-shaped, horseshoe-like, con- 
duplicate or semi-circular, wholly or partially enclosing the endosperm. 
1. Polycnemeae. Polycnemum. 
2. Bcteae : Beta. 
3. Chenopodieae : Chenopodium. 
4. Atriplicieae . Spinacia, Atriplex. 
5. Carnphorosmeae . Camphorosma, ICochia. 
6. Corispermeae: Corispermum. 
7. Salicornieae : Salicornia. 
B. SPIROLOBEAE. Embryo spirally twisted: endosperm 
wanting or divided into two masses by the embryo. 
8. Sarcobatideae : Sarcobatus. 
9. Suaedeae: Suaeda. 
10. Salsoleae : Salsola, Haloxylon, Halimocnemis. 
Benth. -Hooker and Warming include Basellaceae in C., and place 
the order in Curvembryae. 
Chenopodium (Tourn.) Linn. Chenopodiaceae (3). 60 sp. temp. 9 in 
Brit, (goosefoot, lamb’s-quarters, Good King Henry, &c.). The fruit 
in many sp. is dimorphic ; some have horizontal seeds, some vertical 
(esp. on the terminal twigs of the cymes). C. anthelminticum ( am - 
brosioides ) L. is the worm-seed or Mexican tea, whose essential oil is 
used as a vermifuge in the U. S. C. Quinoa Willd. is an important 
food plant in S. Am.; its seeds are boiled like rice. It is also recom- 
mended as a substitute for spinach. 
Cherleria Hall. = Arenaria Linn. 
Chickrassia A. Juss. Meliaceae. r sp. India, Ceylon, C. tabularis 
A. fuss., which yields a good and durable timber, known as Indian 
red wood, Chittagong wood, or white cedar. 
Chilocarpus Blume. Apocynaceae (1. 1). 10 sp. Indo-mal. 
Chimaphila Pursh. Pyrolaceae. 4 sp. N. temp. 
Chimonanthus Lindl. Calycanthaceae. 2 sp., China, C. fragrans 
Lindl., often cultivated, being a shrub with very fragrant firs, which 
come out early in the year before the leaves and show marked
