O. leve, Lindl. in Bot. Reg. 1844, t. 39; Fol. Orchid. Odontogl. p. 18; Walp, 
Ann. v. vi. p. 842. ‘ 
One of the earliest introduced species of the genus, having 
been sent to England from Guatemala by both Mr. Skinner 
and Hartweg, and having flowered in the Horticultural 
Society’s Gardens early in 1842. It is fairly well figured in 
the ‘ Botanical Register,’ but evidently from a plant not so 
well grown as ours, its pseudobulb being grooved, as if 
they had shrunk, the leaves being smaller and the flowers 
duller coloured. It has two described closely allied congeners 
published since as Odontaglossa, viz., 0. Karwinskei, Rehb. f. 
(Oncidium. Lindl. Sert. sub. tab, 20; Cytrochilium, Lindi. in 
Bot. Reg. sub. tab. 1992; Miltonia, Lindl. in Journ. Hort. Soc. 
vol. iv. p. 83, eum tc.); and O. Reichencheimu, Lindl. and 
Rehb. f. lc.) which are probably both forms of the same plant. 
O. leve has flowered at Kew repeatedly ; for the first time 
in June, 1864, from plants imported from Guatemala ; it is 
very fragrant. :
