ODOXTOGLOSSUM. 547 



O. CITROSMUM ROSEUM. — A very fine variety of 0. citrosmum, having the 

 same habit and manner of growth as the type, and producing its beautiful 

 flowers on long drooping racemes. The sepals and petals are white, and the lip 

 a bright rose colour. There are many varieties of this, some of them having 

 more colour than others ; the best form we have seen is that figured by 

 Mr. Warner, as quoted below. When the plant is in bloom the pot should be 

 suspended from the roof, so that the pendent racemes may hang down naturally, 

 in which position it produces a charming effect. — Mexico.

O. CLOWESII.— See Miltonia Clowjjsii. 



O. CONSTRICTUIVI, Lindl. — -Although not a large-flowered species, this is a 

 very pretty plant, producing a large branching panicle of gaily-coloured blossoms. 

 The pseudobulbs are rather large, ovoid, compressed, ribbed, supporting a 

 pair of linear-lanceolate leaves 1 foot long, of the same dark green colour, 

 and a slender scape, Ij feet long, supporting a loosely branched panicle of 

 equal length. The flowers are 1| inch across (in wild specimens 3 inches) ; 

 the oblong lanceolate sepals and petals are bright yellow blotched with orange 

 or reddish-brown, the colours often disposed in longitudinal bars, the lip 

 distinctly fiddle-shaped, with an apiculus, white with a pair of oblong rose- 

 cdloured blotches in the middle contracted portion, and a pair of small toothed 

 crests on the disk. — La Guayra ; Caracas.

O. COOKIANUM, Bolfe. — ^When this natural hybrid was first exhibited 

 before the Royal Horticultural Society, by Malcolm S. Cooke, Esq., of 

 Kingston Hill, on November 14th, 1891, without a name, it received an award 

 of merit. It was stated to have been received as 0. hlandum, but it is quite 

 different, and Mr. Rolfe believes it to be a natural hybrid between 0. triumjjhans 

 and 0. Sanderianum, though he adds 0. hlandum may have been one of the 

 parents instead of the latter. It is described as follows : — " Flowers stellate, 

 sepals lanceolate, acuminate, 1\ inch long by 5 lines broad, deep yellow, with 

 numerous smallish blotches of deep chestnut, which pass into lines at the 

 extreme base ; petals similar, but a little shorter ; lip much hke 0. Sanderianum 

 in shape, stalk 4 lines long, yellow, with a few light chestnut spots, blade sub- 

 pandurate, abruptly and shortly acuminate, 1 inch long by 6 to 7 lines broad, 

 white, with large bright chestnut blotch in front of the crest, and a few small 

 spots near the margin" (R. A. Rolfe, in Gardeners' Chronicle, 3rd ser., 1891 

 X. p. 696). — Sew Grenada. 



O. CORADINEI, Bchh. f. — A distinct showy Odontoglot supposed to be a 

 natural hybrid between 0. triumphans and some species of the 0. odoratum 

 group. The pseudobulbs are elongate ovate compressed, with ligulate oblong
