produced in flexuose panicles in great profusion ; the sepals 

 and petals are obovate obtuse, yellow, blotched with red 

 above, and the lip has the transverse middle lobe narrowly 

 clawed, two-lobed, yellow, stained with red at the base. 

 From its distinct habit it makes a good addition to a 

 collection. — Brazil. 



0. Stelligerum, Echb. f. — This is an interesting and free- 

 flowering species, allied to but little resembling 0. hastatum. 

 The stellate flowers are produced in panicles, the oblong ligu- 

 late sepals and petals yellowish, with many brown spots, the 

 lip yellowish white, with a darker yellow callus, the lateral 

 lobes short obtuse-angled, the isthmus narrow, and the mid- 

 lobe roundish cordate, shortly and abruptly cuspidate. — 

 Mexico. 



0. SUperbiens, Bchh. f. — This handsome species belongs to 

 the same section as 0. macranthum and 0. serratuin. The 

 pseudobulbs are elongate ovate compressed, about four inches 

 long ; the leaves are about a foot long, linear-oblong acute, 

 leathery, keeled ; and the scape is two to three feet long, in- 

 cluding a lax flexuous panicle of twenty to thirty flowers, 

 which are two and a half inches in diameter. The sepals are 

 long-clawed, the upper trulliform much crisped, the apex 

 reflexed, the lateral more ovate and less crisped, all chocolate 

 brown, tipped with yellow ; the petals are smaller, cordate 

 oblong, recurved, with a shorter broader claw, yellow in the 

 apical half, barred with chocolate in the basal portion ; the 

 lip is much smaller, revolute, trulliform, of a blackish purple, 

 with the crest yellow. — New Grenada; Venezuela.

0. tigrinum, LI are and Lex. — One of the most beautiful 

 and free-blooming of the large-flowered yellow Oncids. The 

 pseudobulbs are ovate compressed, blunt-edged, three inches 

 long, bearing two or three lanceolate oblong leathery leaves, 

 and from the base a panicle of numerous large showy flowers, 

 which have the odour of violets. The sepals are linear-oblong, 

 acute, wavy, revolute at the margins, the lateral ones curving 

 upwards so that all three stand above the base of the lip ; the 

 petals are similar in form, and also curve upwards ; both 

 sepals and petals are yellowish green, heavily marked with 

 transverse bands of dark chestnut brown ; the lip is three- 

 lobed, with the central part transversely oblong reniform, one
