Oncipium Jonxstanum, Reichenbach fil., in Gardeners’ Chronicle, N.8., Xx., 781. 
The Oncidiums are among the most popular of Orchids, and form a most 
useful group, there being so much variety of colour among them, they are, moreover, 
valued on account of their lasting qualities and the graceful character of their 
inflorescence. The subject of the present illustration is very distinct as regards the 
character of its foliage, as well as in the colouration and spotting of its Howers. 
We have, indeed, other Oncids with the peculiar quill-like foliage, but they are different 
—m the colouring of their flowers from Oncidiuwm Jonesianun, which is new and 
beautiful, and has only been introduced a short time since from Paraguay by Mr. 
Horsman. It was flowered in the well-known collection of W. Lee, Esq., Downside, 
Leatherhead, and from this source our artist made his very satisfactory sketch. : 
Oncidium Jonesianum is an evergreen plant, with subulate tapering foliage, ‘ 
tepresented in our figure ; it : produces a drooping raceme of flowers, in oe ~ 
Sepals and petals are of a pale yellowish green colour, spotted with brown, — ei 
ip is large and white, with crests of a reddish brown colour. It blooms during 
September and October, and lasts for some time in beauty. ; 
is is one of the species which takes but little room, and will succee =
