Spiranthera
(from speira, a spiral, and anthera, an anther; alluding to the spiral anthers). SYN. Terpnanthus. ORD. Rutaceae. A monotypic genus. The species is a very handsome, sweet-scented, highly glabrous, stove, evergreen shrub. It thrives in a compost of peat and sandy loam. Propagation may be effected by cuttings of half-ripened wood, inserted thinly in sand, under a glass, which must be occasionally removed in order to prevent them from damping off, which they are otherwise likely to do.
S. odoratissima (very sweet-scented). fl. white, showy, sweet-scented, corymbose, axillary and terminal; calyx five-toothed, cup-shaped; petals five, elongate-linear, pubescent, imbricated; disk thick, erect, columnar; stamens five, inserted at the base of the torus. July. l. alternate, petiolate, trifoliolate; leaflets gland-dotted, acuminate, entire, glaucous beneath. h. 6ft. Brazil, 1823.
