leaves sharp-pointed and earinate, 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 I am acquainted through an extensive unpublished collection of excellent 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. Tliis 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 lesjleurs sefanent ; 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-bulhs, 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 earinate, 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. Sejmls 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."
