THREE, ONCIDIUMS. 



ONCIDIUM PULVINATUM was first 

 cultivated by Mr. Richd. Harrison, of 

 Aigburth, Liverpool, who received it 

 from his brother William at Rio de Janeiro in 

 1838, and he probably obtained it at Novo 

 Friburgo, its known habitat. It closely 

 resembles divaricatuni in liabit and aspect, 

 but is distinguished from tliat species by its 

 differently shaped labellum, the crest of which 

 is entire (not lobed). Flower sjiike slender, 

 flexuose, 5-7 or more feet long, loosel)" 

 paniculate. Flowers ver\- numerous, sepals 

 and petals having the basal half red-brown, 

 the apical half )'ellow ; li]) light yellow 

 spotted with red ; crest whitish si)otted with 

 red. 



Oncidium nanum is a curious little plant 

 deserving of notice on account of its richly 

 coloured flowers. It was first discovered by 

 Schomburgk growing on the trunks of trees 

 on the banks of the Pomeroon River m 

 British Guiana, and sent by him to Messrs. 

 Loddiges in 1842. Accorfling to Lindley it 

 was also detected b\- .Spruce near the junction 

 of the Rio Negro with the Amazon. There 

 are no j^seudo-bulbs, the leaves being 

 produced from a creeping rhi/.ome. Scajies 

 decumbent, jianicled, the branches short and 

 few flowered ; sepals and petals yellow 

 spotted with brown ; lip bright yellow. 



Oncidium pumilum is an interesting species 

 which appears to have been first cultivated 

 by Dean Herbert, at Spofforth, Yorkshire, in 

 1825, whither it had been sent from Rio de 

 Janeiro by one of his correspondents who had 

 found it growing on the trunk of a tree near 

 Botofogo. It has since been gathered in 



several localities in the neighbourhood of Rio, 

 where it forms large tufts on the trunks of 

 several kinds of trees. There are no pseudo- 

 bulbs, the leaves being produced from a 

 creeping rhizome. Scapes about 4 inches 

 long, paniculate, the branches short, the 

 flowers small and crowded ; sepals and 

 petals yellow spotted with red-brown ; the 

 three-lobed lip yellow. 



Trichopilia fragrans. 



TRICHOPILIA FRAGRANS. 



THIS pretty species was originally 

 discovered by Hartweg about the 

 year 1841, near Popayan in southern 

 Colombia, and a brief description of the 

 flower from his herbarium specimen was 

 published by Lindley in the Botanical 

 R("^}s-frr of 1844. In the meantime a 

 'i'richoi)ilia had been detected on the Sierra 

 Nevada of Merida m western Venezuela by 

 r.inden, who named it T. Candida, a name 

 which Lindley adopted in Ins enumeration of 

 the Orchids discovered by Linden, but 

 Lmd en s i)lant was afterwards referred to 

 T. fragrans by Reichenbach and later by 

 Andre to the T. nobilis of that author, which 

 he riglitl)- reduced to a variety of T. fragrans 

 on the occasion of its being figured in 

 the Illnslraiion Jiorticolc. But so many
