whole labellum blotched with blood-coloured spots. Column 

 long and curved, and comparable to the head and neck of a 

 swan. The flowers are more singular than beautiful, but they 

 compensate in fragrance for their want of brilliant colours : the 

 purest odour of vanilla is exhaled by them when they have been 

 open a short time, especially in the morning. Introduced from 

 the woods of Surinam, to the collections of Messrs. Loddiges and 

 the London Horticultural Society, by J. H. Lance, Esq. It has 

 thriven treated as catasetums are, but seems to require the greatest 

 heat that is ever obtained in a damp stove: it is disposed to in- 

 crease itself pretty freely. [Bot. Reg., March.)

Dr. Hooker published, in 1826, this species by the name 

 C. inapertum ; Dr. Nees von Esenbeck had, in 1824, published it 

 by the name C. purum. Dr. Hooker has now refigured, and in 

 part described, the species, and adopted the prior name by Dr. 

 Nees. Plants of it are in the botanic garden at Liverpool, and 

 in the collection of C. Horsfall, Esq., of Liverpool. Upwards of 

 twenty flowers are shown in the spike figured : " they are, per- 

 haps, the smallest of the concave lipped species ; and of a uni- 

 form pale yellow-green colour, the inside of the lip only excepted, 

 which is of a purplish-brown colour." {Bot. Mag., March.)

Has been long introduced, but is rare : there are plants of it 

 in the collections of C. Horsfall, Esq., Liverpool, and Earl Fitz- 

 william, at Wentworth. Scape from the centre of the leaves, 

 terminated by a raceme of ten to twelve handsome but mode- 

 rately sized flowers. Calyx purplish green. Petals white, tinged 

 with pale green, and variously spotted with purple. [Bot. Mag.,

Its leaves have smooth edges, like those of T. media : the 

 margins of those of T. uvaria are serrulate. The tubular pe- 

 rianths of its flowers are red while in the more youthful state, 

 and progress into an orange yellow one : when full-grown, they 

 are l^in. long. The flowers are densely disposed into a raceme 

 4 in. long. It is a beautiful perennial plant, and quite hardy ; 

 and produces offsets in plenty. At Spoffbrth, the residence of 

 the Hon. and Rev. W. Herbert, it always flowers before or soon 

 after midsummer : other tritomas flower late in the year. Mr. 

 Herbert has named it (in Sweet's Hortus Britannicus) after Mr. 

 Burchell, who introduced it from the Cape of Good Hope. [Bot, 

 Beg, March.)
