TRICHOCENTRUM ALBOPURPUREUM. 
[PLaTE 204. | 
Native of North Brazil. 
Epiphytal. Pseudobulbs minute ovoid tufted, monophyllous, producing — flat 
ereeping roots, which cling firmly to the surface of the block. ves sessile, 
lanceolate-oblong acute, four to six inches long, pale glossy green, fleshy, keeled 
beneath. | Peduncles one-flowered, springing from the base of the diminutive 
pseudobulbs. Flowers showy, about two and a half inches across in each direction, 
the parts spreading; sepals cuneate-ligulate acute, over an inch long, the dorsal 
one slightly incurved, the lateral ones somewhat deflexed, bright cinnamon on the 
inner face, and tawny yellow on the outer; petals similar, but less narrowed 
towards the base; lip adnate to the base of the column, projected forwards, 
panduriform or subquadrate, bilobed at the apex, an inch and a_ half long, and 
rather less in breadth, the posterior half, which is narrowed at the base into a 
short dilated claw, bearing on each side a large blotch of rich magenta-purple, the 
broader anterior part white, with a flabellate arrangement of ros purple veins, 
narrowed backwards in the centre, and becoming yellow where it joins the crést of 
four linear rosy purple keels. Spur stout, curved half as long as the ovary. 
Column white, short, with the wings produced above into a pair of curved conical 
horns.

Trichocentrum is a small genus of very pretty Orchids, the species we here 
figure being one of the best of them. It is a very free-blooming plant, as may 
be seen from our illustration, the sketch for which was taken from a neatly grown 
plant in the well-known collection of Mr. J. E. Bonny, Downs Park Road, Hackney. 
Trichocentrum albopurpureum is a dwarf evergreen plant, with foliage about 
six inches in length, of a light green colour; the flowers proceed from the base of 
the minute pseudobulbs on peduncles about two inches in length, and have a 
pretty drooping position; the sepals and petals are reddish brown inside, dull yellow 
outside, and the lip is white, having two large violet-purple patches, one on either 
side of the crest, and a few pale radiating veins of the same colour on its anterior 
part. It blooms during the summer months and lasts some time in beauty. 
These plants are pretty dwarf-growing epiphytes, and should be in every 
collection, as they occupy so little room. They do well on blocks, or rafts, or in 
small baskets suspended from the roof, so that they receive all the light possible, 
but they must be shaded during the hot part of the day, since small plants like
