146 RUTACE.E. Rura. 
I. PEGANUM. Linn.; Gertn. fr. t. 95; Lam. ill. t. 401. 
Calyx 5-parted, segments foliaceous, oblong-linear, entire or pinnatifid, 
persistent. Petals 5, nearly equal, entire, 3-nerved. Stamens 15 (some of 
them abortive), shorter than the petals: filaments dilated and membranace- 
ous at the base: anthers linear-oblong. Torus short, beneath expanded into 
a short thick cup-shaped disk, bearing the petals and stamens on the outer 
margin. Ovary seated on the torus or gynophore,iglobose, 3-lobed, 3-celled: 
ovules numerous in each cell, suspended. Style simple, erect, clavate and 
3-angled at the apex, at length spirally twisted. Fruit slightly stalked, cap- 
sular, globose, 3-furrowed, 3-valved, loculicidal. Seeds fewer than the 
ovules, scrobiculate. Albumen closely adhering to the integument of the 
seed.—Perennial, branched, herbaceous plants. Leaves alternate, simple or 
multifid, with linear segments, not dotted, with two short bristle-shaped 
teeth (stipules) at the base. Flowers white.

IL. RUTA. Linn. ; Gertn. fr. t. 111; Lam. ill. t. 345. 
Calyx 4-partite, at length deciduous. Petals 4, longer than the calyx, 
unguiculate: the limb vaulted, usually waved or jagged. Stamens 8, longer 
than the petals: filaments subulate-filiform, glabrous: anthers ovate, obtuse. 
Torus or gynophore usually broader than the ovary, marked round about with 
8 nectariferous pores, bearing the petals and stamens at the base. Carpels 4, 
partly combined by means of the central axis into one 4-lobed ovary : ovules 
. 6-12 (or rarely 2 collateral), in each cell. Styles 4, distinct at the base 
where they spring from the inner angle of the carpels above the common a315, — 
united upwards into a single pistillum, which is attenuated towards the apex. — 
Stigma 4-furrowed, not thicker than the style. Capsules 4, partly united, 
dehiscing internally at the apex. Seeds dotted.—Perennial or suffrutescent 
herbaceous plants. Leaves alternate, exstipulate, pinnated, or decompound, 
with pellucid dots. Flowers yellow or rarely white, disposed in terminal eo- 
rymbs or racemes: the number of parts occasionally augmented by a fourth.

III. CYMINOSMA. Gertn. fr. 1. p. 58. 
Calyx short, deeply 4-lobed. Petals 4, much longer than the calyx, PAP 
row, revolute at the apex. Stamens 8, longer than the petals: filaments flat, 
subulate, with woolly margins near the base: anthers ovate. Torus forming 
a gynophore slightly broader than the ovary, and nearly continuous with it, 
tomentose. Ovary seated on the torus, fleshy, tomentose, 4-celled: 0 ! 
2 in each cell, superposed. Style terminal, short, glabrous, ending ina 
suleated stigma. Fruit drupaceous : sareocarp, thick, fleshy, closely attach” — 
to the nut ; nut thick, hard, bony, 4-celled. Seeds solitary in each cell.—Trees 
or shrubs. Leaves opposite, between lanceolate and elliptical, simple, entre;
