T. TIGRINUM, Linden et Rchh. f. — ^A remarkably handsome and desirable 

 species, which produces its blossoms while in a very small state. Its oblong 

 foliage reminds one of a miniature Oncidium Lanceanum, being more or less 

 dotted with deep red. The peduncles are produced from the base of the leaves, 

 and bear one or two sweet scented flowers, of which the ligulate-lanceolate 

 sepals and petals are greenish-yellow, transversely barred and distinctly spotted 

 with purplish-brown; and the lip, which is very large in comparison to the size 

 of the flower— 1| inch long, and nearly 2 inches across the dilated apex— is 

 broadly cuneiform, deeply bilobed, pure white, with a yellow crest on the disk, 

 and on each side at the base a wedge-shaped blotch of purple. A variety named 

 SPLENDENS has larger and more intensely coloured flowers. — Ecuador.

 or blotched with orange. — Feru.
