It was in the green-house of Mr. Whitley, Nurseryman at Old Brampton, that we first saw this plant in flower, on the 25th of March 1799; previous to this period it had flowered in the Royal Garden at Kew, and specimens of it had been deposited in the Herbarium of Sir Joseph Banks, under the name of Diosma serratifolia.
It forms a neat pretty shrub, which is rendered more desirable by its early flowering; its blossoms are pure white, set off by Antheræ of a lively purple colour; the whole plant has a strong scent very like that of Pennyroyal, but more powerful.
This shrub is one of the many which have been raised within these few years from Botany-Bay seeds, is a greenhouse plant, of easy culture, blows freely, and is readily increased by cuttings.
Descr. Twigs somewhat angular, reddish purple; Leaves opposite, narrow, on very short footstalks, spreading, slightly truncated at the extremity, finely toothed, a transparent gland in the angle of each tooth, beset on both sides with numerous glands, which project and give to the upper surface a manifest roughness; Flowers from the alæ of the leaves, opposite, on peduncles about one-third of an inch long, usually supporting one, sometimes two flowers; Calyx composed of five leaves which are tinged with red and permanent; Corolla five petals, white, ovato-lanceolate; Stamina filaments five, white, hairy, at first upright, afterwards bending back betwixt the petals; Antheræ before they open purple; Pollen yellow; Nectaries of two kinds, five white, springing up between each filament, and which may perhaps be considered as so many imperfect stamina, they are broader, much smoother, and about one-third of the length of the filaments, terminating in a transparent gland instead of an anthera; five green, forming a kind of calyx to the germen, from the top of which they spring, they consist of five roundish, fleshy, spreading, green leaves, edged with hairs; besides these, there is a glandular ring at the base of the germen; Style white, tapering, very hairy; Stigma simple; Flowers usually dropping off without ripening the seeds.
