Lin. syst. Polydndria, Trigynia. Calyx rotate, 5-toothed, 
replete with an annular gland or rather disk. Petals wanting. 
Berry many-seeded. A small shrub, with numerous twiggy, 
straight, smooth branches. Leaves linear bluntish, furnished 
on each side with a glandular tubercle. Flowers in spikes, yel- 
low. Peduncles at length becoming spinescent. 
1 O. sacca‘tus (Delile. 1. c.) kh. F. Native of Upper 
Egypt.

tion of this plant. 
Orver XVII. DATI’SCEZ (this order only contains the 
genus Dalisca.) R. Br. in Clapp. and Denh. trav. appendix. 
Flowers dioecious from abortion. Male flowers with the 
calyx of 5 linear equal acute sepals. Corolla wanting. Sta- 
mens about 15, inserted in the receptacle, very short; anthers 
oblong, obtuse, much longer than the calyx, 2-celled, bursting 
inwards. Female flowers, with a superior, erect, bidentate, 
minute, permanent calyx. Corolla none. Ovary oblong, in- 
ferior. Styles 3, short, cloven ; stigmas simple, oblong, shaggy. 
Capsule prismatic, crowned by the permanent styles, with 3- 
valves and 1-cell, with a hole at the top as in Reséda. Seeds 
small, numerous, ranged along 3-4 or 5 placentarious nerves in 
the capsule. Albumen pale, fleshy. Embryo straight, terete, 
with very short cotyledons, and a long thick centrifugal radicle. 
This order comes very near to Resedacee, but differs in the 
seeds being furnished with albumen, in the flowers being apeta- 
lous, in the calyx being adherent, and in the fruit being inferior. 
Large coarse perennial herbs, having the appearance of hemp, 
with pinnate leaves and long spiked racemes of insignificant 
flowers, resembling those of some species of Reséda ; they ap- 
pear to be yellowish-green from the colour of the anthers. Ripe 
seeds of these plants are easily introduced in a living state from 
their native countries on account of the copious albumen. The 
genus Tetrdmelis of R. Br. belongs to this order, and is remark- 
able in the quaternary division of every part of the dioecious 
flower. The plant is a native of Java.

Sepals 4-5-7. (f. 55. b.), definite in number, connected a little 
together at the base. Petals equal in number with the sepals 
and alternating with them, very rarely absent (f. 55. a.). Sta- 
mens inserted into the thalamus or receptacle, equal in number 
with the petals, but sometimes double or multiple that number 
(f. 55. 56. a.) and sometimes these are changed into necta- 
riferous scales. Ovary ovate-globose, free, sessile (f. 55. c. 
f. 56. d.) or on a very short stipe. Style absent, or when pre- 
sent filiform (f. 56. f.). Stigmas equal in number with the 
valves of the ovary, more or less distinct (f. 56. e.) from each 
other. Fruit l-celled (f. 56. g.) sometimes indehiscent and 
fleshy, sometimes capsular, 4-5-valved, filled with a fine pulp 
inside. Seeds few, thick, usually inwrapped in a dry thin pulpy 
pellicle ; these seeds are fixed to the valves of the capsule, not to 
the margin as in Capparidee, nor to a longitudinal line as in 
Violariée and Passifloree, but with the placentas branched in the 
disk of the valves, and the seeds adhering somewhat irregularly, 
and as if it were areolately, to these branched placentas. Albu- 
men fleshy, rather oily. Embryo straight, slender, with the 
radicle turned towards the hilum. Cotyledons flat, oval, leafy. 
This order contains small tropical trees or shrubs without sti- 
pulas. The leaves are alternate, simple, feather-nerved, usually 
entire and coriaceous, on very short footstalks. Peduncles ax- 
illary and many-flowered. Flowers small, insignificant, often of 
distinct sexes, they are yellow, white, or greenish. Fruit when 
fleshy eatable. This order is allied to Capparidee and Rese- 
dacee, but it differs from these as well as from all dicotyledonous 
plants in the seeds being fixed to branched parietal placentas. 
Nothing is known of the properties of the plants contained in 
The seeds are difficult to introduce in a living state 
from their native countries.
