A distinct but somewhat variable species that lias probably not 



been seen in British collections for some years past, although from 



the many localities in which it has been gathered it cannot be 



assumed to be a rare species^ and may therefore be expected to 



appear at any time among importations of Central American Oncids. 



It was originally sent by Mr. G. Ure Skinner from Guatemala to 



Mr. Bateman, and subsequently to the Horticultural Society of London 



by Hartweg, who found it on the mountains of Oaxaca, at 8,000 — 



9,000 feet elevation; it was afterwards gathered by Galeotti at 



San Pedro, Nolasco, Talea, and other places in southern Mexico. 



On. haematochilum. 



Pseudo-bulbs none. Leaves oblong, acute, 9 — 12 inches long, very 



leathery, dull green spotted with reddish brown. Scapes dull purplish 



red, 15 — 24 inches long, panicled above, many flowered. Flowers 



2 inches in diameter ; sepals and petals clawed, yellow-green heavily 



blotched with chestnut-brown ; the dorsal sepal sub-orbicular, the lateral 



two free, oblong ; petals obovate-oblong, undulate : lip broadly clawed with 



two oblong auricles at the base, the blade transversely oblong, emarginate ; 



the claw, auricles and crest dark rose-purple, the blade sanguineous red 



with a yellow margin spotted with red ; crest five-partite, of which the

First imported in 1847 by Messrs. Loddiges from New Granada, 



it is said, and since that date it has appeared at intervals in 



various orchid collections in Great Britain ; its habitat is, however, 



virtually unknown to science. Its nearest affinity is Oncidium 



Lanceanum, from which the differently shaped crest of the labellum 



chiefly distinguishes it. The specific name is derived from «t/ia, 



"blood," and x^'''^"^. "^ lip-" 



On. Harrisonianum. 



Pseudo-bulbs orbicular, generally compressed and disk-like, about an 

 inch in diameter, monophyllous. Leaves linear-oblong, 3 — 6 inches long, 

 recurved, fleshy, glaucous green densely spotted with grey. Scapes slender,
