LXII. FICOIDER. 135 
16. LIMEUM, Linn. 
Calyx 5-parted ; sepals connate at base, herbaceous, with 
membranous edges. Petals 3-5 or 0, clawed. Stamens 7 
(rarely 5-8-10), hypogynous. Ovary subglobose, of 2 hemi- 
spherical carpels, united by their flat sides; styles 2, slender. 
Fruit of 2 separable, 1-seeded, indehiscent, hemispherical, 
wingless, dorsally-pitted, or echinate carpels.—#1. Cap. i. p. 
152. 
Small, herbaceous or woody, prostrate or erect perennials or annuals. 
Leaves simple, entire, alternate, slightly fleshy, often glaucous and glabrous, 
sometimes glandularly hairy. Inflorescence cymoid. Flowers small, white 
or greenish-white.—8 species, dispersed. 
17. TRIANTHEMA, Lam. 
Calyx 5-parted; sepals coloured within, mucronate below 
the apex. Petals 0. Stamens 5-10 to 40 or 70, on the tube 
of the calyx. Ovary 2-celled or 1-celled by abortion ; stig- 
mas 2, filiform. Capsule opening by a transverse slit at or 
below the middle (cirewmscissile). Seeds few or many in each 
cell, sometimes solitary.—Diplochonium, Fenzl; Fl. Cap. i. 
p. 473; and Trianthema, Fl. Cap. ii. p. 598. 
Fleshy herbs, with opposite, entire leaves, and axillary, sessile, solitary 
or clustered flowers.—3 Cape species, on the North-Western frontier. 
Orper LXIII. UMBELLIFERA. 
Flowers usually bisexual, small. Calyx adhering to the 
ovary ; limb 5-toothed or obsolete. Petals 5, on the outside 
of a fleshy epigynous disk. Stamens 5, alternate with the petals 
and inserted with them. Ovary inferior, of 2 carpels, 2-celled ; 
ovules solitary, pendulous; styles 2, divergent. Fruit dry, of 
2 easily separable carpels (mericarps), which cohere by their 
inner face (commissure), and are attached to a central slender 
axis (carpophore), but at maturity often separate from it, and 
are for a time pendulous from its summit. Each carpel (meri- 
carp) is indehiscent, having 5 longitudinal (primary) ribs, and 
often also 4 (secondary) intermediate ribs, the ribs being se- 
parated by furrows. In the substance of the pericarp are linear, 
longitudinal oil-vessels (vitt@), which sometimes are opposite 
the furrows, sometimes the ribs. Albumen copious, horny. 
Embryo minute.— Mostly herbs, rarely shrubs. Leaves alter- 
nate, with sheathing petioles, mostly cut or lobed.—(Several 
terms often used in describing plants of this Order are given 
above, within brackets, immediately after the explanation of 
each. The characters which distinguish the genera are mostly
