TKICHOCENTRUM. 587 



T. nivalis, Hort. — This plant, which resembles T. alba, has 

 erect terete stems, seldom exceeding eighteen inches in 

 height, and are furnished with glaucous distichous leaves, 

 about six inches in length, which fall off during the resting 

 season. The flowers are produced on a short raceme from 

 the apex of the stem, each cluster containing some five or six 

 pure white blossoms. — Sylhet. 



T. VeitcMaiia, Rchh. f. — This plant, which has for some 

 time been known to us under the name of T. Wrigleyana, was, 

 we believe, first raised and flowered by the late Mr. Geo. 

 Toll, of Manchester, who named it after E. Gr. Wrigley, Esq., 

 and subsequently sold us the stock. Since then it has been 

 exhibited by Messrs. Veitch and Sons under the name of 

 T. Veitchiana, at the same time as exhibited by us under the 

 name of T. Wrigleyana, at the Royal Botanic Society's Show, 

 in May, 1885. It is a hybrid between T. BensonicB and 

 T. MarshalUana ; the sepals and petals are white, just tinged 

 with mauve at their tips, the keels of the disk are of a peculiar 

 orange-purple, the anterior part of the lip is fine mauve-purple, 

 and the superior portion of the lip white, with some mauve - 

 purple veins. — Garden hybrid. 



Syn. — T. Wrigleyana. 



TriCHOCENTRUM, PiJppig and Endlicher. 

 {Tribe Vandese, subtribe Oncidiese.) 



This is a small genus of dwarf epiphytes, with small 

 monophyllous pseudobulbs, and radical scapes, bearing one 

 or two flowers of medium size. Many of the species are 

 interesting only from a botanical point of view ; there are, 

 however, some few exceptions to this rule, of which the species 

 here quoted are examples. They have free spreading sepals 

 and petals, and a lip which is connate with the base of the 

 column into a pitcher, and is produced into a longish spur, 

 the middle lobe being flattened out, broadly two-lobed, and 

 much longer than the sepals. Eight species are recorded 

 from Brazil and Central America.
