Jusstma. ONAGRARI 2. 335 
ORDER LXV.—ONAGRARL:XE. Juss. 
Calyx tubular, with the limb usually quadripartite, sometimes sex- 
partite, very rarely 3-2-partite, the lobes sometimes cohering in va- 
rious degrees: swstivation valvular. Petals usually equal in number to 
the lobes of the calyx, regular (or rarely irregular), inserted at the top 
of the tube: zstivation twisted. Stamens definite: filaments distinct : 
anthers oblong or ovate: pollen triangular. Ovarium plurilocular, co- 
hering with the tube of the calyx: ovules indefinite, rarely definite : 
style filiform: stigma capitate or lobed. Fruit baccate or capsular, de- 
hiscent or indehiscent, 1-2—4-celled. Seeds indefinite, rarely definite, 
or solitary in each cell. Albumen none. Embryo straight: radicle 
long and slender, pointing to the hilum, cotyledons short, equal, or 
rarely unequal.— Leaves alternate or opposite, not dotted. 
This order is sometimes divided into three :—1. Onagrarie, properly so called, 
which have numerous ovules in each cell of the ovary ; 2. Cirezacee, with a so 
erect ovule ; and, 3. Hydrocaryes, with a solitary penguins ovule in each cell. As 
a combined order they are distinguished une y from Haloragee by the presence 
ofa style, and much more developed limb to the calyx.

Calyx-tube prism-shaped or cylindrical, cohering with the ovary its whole 
length and not produced beyond it: limb divided down to the ovary into 
4-6 persistent acute segments. Petals as many as the calycine lobes, spread- 
ing. Stamens twice as many as the petals, and deciduous with them. Ovary 
either flattish at the apex, or elevated into a furrowed cone. Style filiform, 
short. Stigma capitate, 4-6-furrowed. Capsule 4-6-celled, oblong, often 
ribbed, opening between the ribs, crowned by the lobes of the calyx. Seeds 
very numerous in each cell, naked.—Herbaceous or rarely slightly shrubby 
plants, growing in marshy situations. Leaves alternate, usually quite entire. 
Flowers axillary, solitary, sessile or shortly pedicellate, with often 2 bracteoles 
at the base, yellow or rarely white.

The above character and synonyms relate solely to the East Indian form 
of the plant; but we have specimens from various parts of America and the 
West ndies, proving that sometimes this species is quite glabrous on the 
tube of the calyx, and sometimes pubescent all over: see Hook. and Arn. in 
Hook. Bot. misc. 3. p. 312. |
