indebted to the Rev. John Clowes of Broughton, a most 
zealous and successful Horticulturist, who received it from 
the Organ mountains of Brazil a few years since. Its flower- 
stem is about a foot high, and is terminated by four or five 
large starry flowers, yellow mottled with brown, while the 
lip is white with a rich violet base. A drawing of it, by 
Miss Mearns, will appear shortly in this work. 
154. CATASETUM longifolium ; foliis longissimis gramineis, racemo cylin- 
draceo pendulo multifloro, sepalis ovatis subrotundis petalorum conformium 
dorso applicitis, labello urceolari a tergo incurvo limbo truncato apiculato 
intus cereaceo glabro margine fimbriato. 
This plant is in several collections where Demerara Or- 
chidacex are grown, and is known as the long-leaved Cate- 
setum which never flowers. It has however at last yielded 
to the good management of Valentine Morris, Esq. of the 
Retreat, Battersea, where it has produced its blossoms abun- 
dantly. It is too large a plant to suit the pages of the 
Botanical Register, and will therefore appea? in the 7th fasci- 
culus of the Sertum Orchidaceum, now in preparation. The 
flowers are bright orange, a little bordered with violet, and 
appear in a drooping raceme, over which they are closely 
packed for the length of a foot or more; they are extremely 
beautiful, and the species is beyond all comparison the hand- 
somest of its genus.

caule longiore, vàginà pilosá caulis medium subequante, flore solitario 
pubescente, ovario tomentoso, sepalis quam petala triplo-longioribus acutis

A curious little plant, transmitted to me by Mr. Booth 
with the following note. 
“ For specimens of this singular plant I am indebted to 
Michael Williams, Esq. of Trevince, who informed me that 
he received it in 1837, with some other Brazilian plants, 
from Lieut. Downey of H. M. Packét establishment at 
Falmouth, and that it has been successfully cultivated in a 
shaded part of the stove, attached to a small bit of wood, and 
kept very moist. 
“The whole plant does not exceed five inches in height. 
The stem, which is one-leaved, is about two inches long, hard 
and round, with a groove on one side, and having for half 
its length a thin, pubescent, brownish covering, thickly
