A native of southern Mexico, first detected by Count Karwinsky 



about the year 1832, and introduced shortly afterwards through him 



by Messrs. Loddiges. Some years later it was received by Mr. 



Bateman from the Botanic Garden at Munich, under the name of 



Oncidium pelicanum, and is figured as such in the Botanical Register 



for 1847. It was afterwards imported by Messrs. Low and Co., and 



distributed by them under the name of On. cruentum.* On. reflexum 



is a bright coloured species frequently met with in orchid collections. 



On. Retemeyerianum. t 



" Pseudo-bulbs nearly obsolete. Leaves cuneate, oblong-acute, more 



or less keeled on the inferior side, very thick with a purplish hue. 



Peduncles stout with a few distant acute sheaths, purplish dotted with 



green, racemed, many flowered ; bracts acutely triangular, one-third to 



one-half as long as the stalked ovary. Flowers fleshy, about 2 inches 



in diameter ; sepals and petals oblong, apiculate, pale yellow with light 



chocolate-brown spots, the petals a little broader than the sepals ; lip 



constricto-pandurate, deep purplish violet, yellow around the crest which 



consists of two pairs of blunt tubercles and an 'interjected' central one. 



Colunm wings rounded, bent downwards, yellow." — Saunders' Refugium

Described as a very curious species, distinct in the colour and 



substance of its flowers, that first appeared in the garden of Herr 



Retemeyer at Bremen, in 1856, and in the following year in the 



nursery of M. Chantin at Paris. Ten years later it was sent to 



the late Mr. Wilson Saunders from Mexico, and thence its native 



country became known; it has subsequently been sent from that 



country to several horticultural establishments, both in England and 



on the Continent. It belongs to the Sarcoptera group of Oncids, 



and has therefore for its allies the better known Oncidium Lanceanum 



and On. Cavendishianum, but anomalous in some of its characters. 



* Fide the late Mr. John Day in Scrap Book No. 10. It is highly probable that Oncidium 

 funereum of the Mexican botanists La Llave and Lexarza is the same species as On. rejlexum 

 described above, but their description is too vague to render the identity certain.
