0. rilbescens, Lindley. — One of the many small-flowered cool 

 Orchids for which we are indebted to the late Mr. Skinner. The 

 present species is a dwarf-growing kind, with oblong com- 

 pressed monophyllous pseudobulbs an inch long, and two to 

 six-flowered racemes as long as the leaves, the flowers having 

 linear-lanceolate straight and very acute sepals, blush white 

 richly spotted with crimson ; the petals are twice as broad, 

 oblong and wavy, spotted only near the base ; and the lip is 

 cordate obtuse, wavy, spotless white, and very pretty. — 

 Nicaragua. 



0. Ruckerianum, Rchb.f.—A rare and handsome Orchid, 

 dedicated to the late Sigismund Rucker, Esq., in whose collec- 

 tion it first flowered. It was one of the first to appear of 

 those mysterious plants which are now generally looked upon 

 as natural hybrids, and is quite a gem, probably having 

 0. oispiwi for one of its parents. The habit and general 

 character agrees with 0. crispum, but the flowers dilfer 

 much in colour. The lanceolate cuspidate sepals and petals 

 are creamy white with a border of deep violet, and a few oblong 

 spots of brown on the inner surface ; the oblong ligulate 

 acuminate lip, which is angulate on both sides at the base, is 

 yellow in that part, and has two or three chestnut brown 

 blotches in the centre. The petals have the chestnut brown 

 basilar lines seen in 0. Ancle rsnnianum. The column is pluri- 

 cirrhose. This is a very distinct and desirable plant. — New 

 Grenada.

0. Euckerianmn splendens, Rchb. /.—A. very superior 



form of the type, in which the flowers are much larger, the 

 sepals and petals broader, the blotches larger, and the mauve 

 colouring of the margin of the sepals and petals considerably 

 deeper. It flowers in June. — New Greyiada. 



0. Sanderianilin, Rchb. f. — A curious and distinct plant 

 which bears stellate flowers from two to three inches in 

 diameter, and in shape and general appearance resembling those 

 of 0. constrictum, only that they are altogether larger and finer. 

 The plant was at first described as being similar to 0. 

 nevadensc, indeed it was supposed to be a natural hybrid 

 between 0. nevadense and 0. nccvium, but we fail to see any 

 resemblance. The sepals and petals are lanceolate acuminate, 

 yellow spotted with reddish brown ; the lip pandurate apicu-
