Lockhartia
(named in honour of David Lockhart, a traveller, who introduced L. elegans). SYN. Fernandezia. ORD. Orchideae. A genus comprising about half-a-score species of stove epiphytal orchids, inhabiting tropical America, from Brazil to the West Indies and Mexico. Flowers small and mediocre, rather long-stalked; sepals and petals sub-equal, free, spreading or laterally reflexed; lip free at base of column; column very short; peduncles in the upper axils, sometimes one or two-flowered, sometimes loosely but slenderly paniculate-branched. Stems fasciculate, erect, simple. Pseudo-bulbs none. The species are more interesting than ornamental. They should be grown on blocks, in a hot, damp stove.
L. acuta (acute). fl. yellow, red; lip linear, three-lobed, the lateral lobes parallel with the middle one; corymbs loosely many-flowered. June. l. acuminate, carinate. h. 6in. Trinidad, 1834. (B. R. 1806, under name of Fernandezia acuta.) L. elegans (elegant). fl. pedunculate, solitary, form the axil of one of the upper leaves; petals pale yellow, oblong-ovate; lip erect, yellow, spotted with red, thick and fleshy; peduncle slender, drooping. l. close-placed, distichous, equitant, ovate-oblong, very obtuse. Stems 3in. to 5in. high. Trinidad, 1827. (B. M. 2715.) L. verrucosa (warted). fl. bright yellow, barred and spotted with red on the lower part of the lip; sepals oblong; lip longer and larger than the ovate petals. l. 1 1/2in. long, keeled, sharp at the extremities. Stems upright, closely imbricated, about 1ft. high. Guatemala, 1841. (B. M. 5592, under name of Fernandezia robusta.)
