leaves sharp-pointed and carinate, without any intermediate tooth between 
the lobes of the lip. The fourth is a very remarkable species, with which 
I am acquainted through an extensive unpublished collection of excellent 
water-colour drawings, by Mons. Descourtilz, of Brazilian Orchideous 
plants, obligingly lent me by Baron Delessert. This species has purple 
panicled scapes a foot and half long, bending gracefully beneath the 
weight of the delicate snow-white flowers. It was found in the ancient 
forests of Brazil, in the province of St. Paul. M. Descourtilz mentions a 
variety of it with flowers of a delicate and pure rose colour. ‘Son inflores- 
cence,” he says, “a lieu dans les mois de Septembre et d’ Octobre, et se 
prolonge jusqu'en Mars sans que les fleurs se fanent ; elles sont inodores.” 
The systematic characters of these species are given below. For the 
following note, and the drawing of the accompanying plate, I have to 
thank Mr. Booth, the very intelligent gardener of Sir Charles Lemon, 
Bart. 
_“ This elegant little plant flowered in May last, in Sir Charles Lemon's 
collection at Carclew, to which it was presented by Captain Sutton, of 
Flushing, near Falmouth, who brought it from Havannah in March, 1835.” 
“ Pseudo-bulbs, very small and nearly hidden by the leaves, oval, deep 
green. Leaves oblong-lanceolate, of a brownish green colour, striated, 
sheathing at the base, thick and fleshy, from 2 to 4 inches long, and about 
half an inch broad, slightly carinate, and tapering to a narrow point. 
Scape produced from the bottom of the small pseudo-bulb, and rising from 
8 to 10 inches high; jointed, round and slender, nearly erect, of a pale 
brownish green, bearing a number of delicately marked flowers arranged 
alternately in a loose sort of panicle. Sepals very small and thin, closely 
laid over the petals which they resemble in colour, but are rather shorter 
and more acuminate. Petals oblong, rounded at the edge, concealing the 
column. Labellum large, and spreading, two-lobed, almost obcordate, 
with a spur at the base, of a pale pinkish colour, beautifully marked with 
bright violet-coloured veins, darkest towards the claw, which has two, 
raised, fleshy, yellow appendages, parallel to, and about twice the length 
of, the column: the latter is pale green and roundish oblong.”
