186 BOTANY. 
ovules one to three, pendulous from a central placenta; style filiform; 
stigma simple. Fruit fleshy, indehiscent, often surrounded by the enlarged 
calyx, unilocular, monospermal. Seed anatropal, pendulous; albumen. 
copious, fleshy; embryo small, at the base of the albumen. Trees or 
shrubs, with simple, alternate, exstipulate leaves, which are, however, 
sometimes abortive. They are chiefly tropical or sub-tropical. Little is 
known in regard to their properties. There are twenty-four genera and 
fifty-three species enumerated. Examples: Olax, Opilia. 
~Orver 190. Ternstramiacem, the Tea Family. Sepals five or seven, 
concave, coriaceous, deciduous, the innermost: often the largest ; sestivation 
imbricated. Petals five, six, or nine, often combined at the base. Stamens 
indefinite, hypogynous ; filaments free, or united at the base in one or more 
parcels; anthers versatile or ‘adnate, dehiscing longitudinally. Ovary 
multilocular ; styles two to seven. Fruit either a capsule, two- to seven- 
celled, opening by valves, or coriaceous and indehiscent. Seeds attached 
to the axis, few and large; albumen 0, or in very small quantity ; embryo 
straight, or bent, or folded back; radicle next the hilum ; cotyledons very 
large, often containing oil. ‘Trees or shrubs, with alternate, coriaceous, 
exstipulate leaves, which are sometimes dotted. They abound in South 
America, and many occur in India, while others inhabit China and North 
America. There are 33 genera and 130 species enumerated. Examples: 
Ternstrceemia, *Gordonia, Camellia, Thea, *Stuartia. 
Species of Thea (T. viridis and bohea) furnish most of the Chinese teas. 
It is a matter of some uncertainty whether black and green teas are derived 
from different species or not. Green teas contain more essential oil and 
tannin than black. The principal varieties of the former are Twankay, 
Young Hyson, Hyson, Gunpowder, and Imperial; the latter include Bohea, 
Congou, Souchong, Oolong, and Pekoe. Perfume is communicated to teas 
by the flowers of Olea fragrans, Cloranthus inconspicuus, and Aglaia 
odorata. The highly ornamental Camellia japonica is a member of the 
order. 
Thea chinensis, Tea plant (pl. 67, fig. 6); a, 6, ¢, three varieties; d, 
pistil and one stamen; ¢, 7, g, ovary. 
Camellia japonica (Japan) (pl. 68, jig. 14); a, branch with a flower; 3, 
two stamens ; ¢, pistil; d, cross-section of capsule; ¢, section of seed. 
Orper 191. Cut#zyacez. Involucre one- to two-flowered, persistent. 
Sepals three, small. Petals five to six, hypogynous, sometimes combined at 
the base, where they are broader. Stamens ten, or indefinite ; filaments 
cohering at the base, and united to the base of the petals; anthers roundish, 
free or united, bilocular. Ovary single, trilocular; style one, filiform ; 
stigma trifid. Capsule three-celled, or by abortion one-celled. Seeds 
solitary or numerous, suspended, attached to a central placenta ; embryo in 
the axis of fleshy or horny albumen; cotyledons leafy, undulated. Trees 
or shrubs, with alternate stipulate leaves, found in Madagascar. ‘Their 
properties are unknown. There are four genera enumerated, including 
probably about eight or ten species. Examples: Sarcoleena, Leptolena.
