placenta confluent, finally free. Seeds 4-6 in each cell, compressed, 
imbricate, with a broad,- marginal wing ; testa thembranous 3 embryo 
large, flat, lying in thin, fleshy albumen, cotyledons ovate, radiele elon-

A glabrous, South African shrub, usually referred by botanists to Onagrariee, 
but, as I think, taking into account the structure of its ovary, the dehiscence of the 
capsule, the imbricated petals, the slightly albuminous seeds, and the general habit, 
more nearly allied to Escaloniee. The name is in honour of Laurence Montin, an 
obscure Swedish botanist.

An erect, seid, twiggy, glabrous, and somewhat glaucous bush, 1-2 feet high. 
Ramuli erect, compressed or angular, pale. Leaves varying from oblong to lanceo- 
late and linear, entire, margined, one-nerved, veinless. Flowers small, white, the 
males in terminal few-flowered, corymbose cymes, the female generally solitary, one

inch or more long, 4-5 lines wide, at length splitting through the centre into two 
boatshaped pieces.

Flowers polygamous. Calyx-tube obconic, adnate with the ovary, 
limb 5-cleft, persistent. Petals 5, inserted on the margin of the calyx- 
tube, longer than the calyx-lobes, sessile, entire, with valvate estivation, 
persistent. Stamens 5, alternate with the petals and inserted with them ; 
filaments short; anthers ovate, 2-celled, slitting. Ovary 2-celled, multi- 
ovulate, with axile placenta. Styles 2, short, connate at first, then 
widely diverging; stigmata capitate. Capsule half-inferior, its conical, 
acuminate apex encircled by the persistent calyx-limb and petals, 
dehiscing scepticidally through the styles. Seeds oblong, subincurved, 
with prominent raphe and leathery testa; embryo... . . t Harv. in

A leafy shrub, 7-8 feet high or more. Leaves 13-2 inches long, alternate, petio- 
late, ovate or oblong, acute, sharply serrate, each serrature mucronate with a minute 
gland, penni-nerved, the 4 
herves prominent on the paler under-surface. Panicles 
axillary, shorter than the leaves, much-branched. Flowers small and green ; petals 
broadly subulate, pubescent on both sides. Anthers hairy, with a fleshy connective, 
often barren and then much reduced in size. Capsule 2-3 lines long.
