_Lonchostoma monostylis_ is a graceful plant with long, thin, erect stems, at the apex of which the flowers are borne. DESCRIPTION:--_Stems_ simple or sometimes branched above, 40 to 50 cm. long, almost woolly, at length becoming glabrous. _Leaves_ erect, adpressed to the branches and almost hiding them, 5 to 6 mm. long, 1·5 to 2 mm. broad, elliptic, obtuse, with a small black mucro, concave, pubescent without, glabrous within, long ciliate. _Flower-heads_ terminal, 1·3 cm. in diameter, about 14-flowered. _Bracteoles_ 5 mm. long, 1 mm. broad at the base, ovate-lanceolate, acuminate, with a long black mucro, membranous long pilose and ciliate. _Sepals_ similar to the bracteoles. _Corolla-tube_, 3 mm. long, glabrous; lobes 6 mm. long, 3 to 3·5 mm. broad, obovate, shortly acuminate, obtuse. _Anthers_ subsessile, 1·5 mm. long, linear, sagittate at the base. _Ovary_ 1 mm. long, globose, pilose; style 2 mm. long, terete, glabrous; stigma minutely bifid.

Plant._ vol. iii. p. 535. =Eulophia Zeyheri=, _Hook. f. Bot. Mag._ t. 7330; _Bolus Ic. Orch. Austr.-Afr._ ii. t. 24; _Fl. Cap._ vol. v. sect. iii. p. 43. This pretty little orchid is quite a common plant in the grass veld during the summer months, and has been extensively gathered by botanical collectors, though strangely enough it is not generally met with in gardens. It has been known to botanists for about sixty years, but under the name _E. bicolor_, until Sir Joseph Hooker in 1893 pointed out that this name had already been assigned to another species in the genus, and published the present name _E. Zeyheri_. The tubers resemble a string of large beads, and send out leaves and roots from the constrictions between the swollen portions. The plant has been successfully grown in Gloucestershire, England, by the late Mr. H. J. Elwes, and should certainly receive the attention of South African cultivators. Our illustration was made from specimens collected by Dr. I. B. Pole Evans, C.M.G., at Irene, near Pretoria.
