Mal. 9. p. 135. t. 69._ [Illustration: _N^o. 325_] This species of Justicia, long since figured in the _Hortus Malabaricus_, and described in the _Species Plantarum_ of LINNÆUS, has been introduced to the Royal Garden at Kew, since the publication of the _Hortus Kewensis_, by Mr. AITON: it is a stove plant, producing, almost the year through, abundance of flowers, distinguished not less for their singularity than their snowy whiteness; the following description, taken from the living plant, is fuller than that of LINNÆUS in the _Sp. Pl._ DESCR. Stalk shrubby, somewhat angular, three feet or more in height, green, very much branched, slightly pubescent; Leaves opposite, standing on short footstalks, ovato-lanceolate, running out to a short blunt point, entire, veiny, a little downy; Peduncles from the alæ of the leaves, alternate, dichotomous, two small bracteæ are placed at each bifurcation; Flowers pure white, inodorous; Calyx composed of five lanceolate, entire leaves, continuing; these, as well as the whole of the plant, are beset with minute transparent globules, visible with a magnifier. Corolla deciduous, tube linear, grooved, pale green, slightly villous, bending a little upward; upper lip very narrow, bent back, bifid at the extremity, the edges toward the base rolled back, so as to make it appear in that part almost tubular; lower lip depending, trifid, segments equal, obtuse at the base, round the mouth of the tube marked with fine purple dots; Filaments two, short, projecting from the mouth of the tube, finally bending back; Antheræ at first yellow, afterwards livid; Germen oblong, smooth; Style capillary, slightly hairy; Stigma bifid. The plant is increased by cuttings; in the _Hort. Malab._ the bruised leaves are described as in use for the cure of cutaneous eruptions. [326] MESEMBRYANTHEMUM VIRIDIFLORUM.

Kew. v. 2. p. 196. Haworth Mesemb. p. 199. Syst. Nat. ed. Gmel. p. 848._ [Illustration: _N^o. 326_] Of the seventy species of Mesembryanthemum described in the _Hortus Kewensis_, this is the only one with green flowers. Mr. MASSON introduced it from the Cape in 1774.
