this plant, though its flowers are perhaps a little larger, its 

 panicle more compact, and its crest very rugose. It should be 

 potted in good fibrous peat, and placed in the cool house. —

0. excavatum Dawsoni, Williams. — Though bearing some 

 resemblance to 0. excavatum, this variety is very much 

 stronger and more robust in all its parts. The branching 

 scapes are five feet long, and upon these its large lovely 

 bright yellow and rich brown flowers are borne in great pro- 

 fusion. When well managed the scapes will often produce 

 upwards of a hundred flowers, and when seen in this state it 

 is truly a noble object. — Peru. 



0. flexuosum, Sims. — A pretty free-blooming and well- 

 known old species, producing its showy yellow spotted flowers 

 in abundance on large branching panicles. It has oval com- 

 pressed two-leaved pseudobulbs, and oblong-lanceolate striated 

 leaves. The flowers have the very 

 small sepals and petals yellow barred 

 with chestnut brown, and the large 

 flat lip transversely roundish oblong 

 and bilobed, yellow speckled over 

 with minute chestnut red dots. The 

 crest is pulvinate with three ridges 

 in front. It blooms at difi'erent 

 times of the year, and continues for 

 several weeks in flower. This plant 

 is invaluable for cutting purposes, 

 the small bright yellow flowers pro- 

 ducing a charming effect when mixed oncidium flexuosum, 

 with other flowers and foliage. There 



are two varieties of this plant ; the one called majxis, which 

 has much larger flowers than the other, though of the same 

 colour, is scarce, and is best grown in a pot with moss. — 

 Brazil.

0. Forhesii, Hooker. — A truly handsome dwarf species, 

 closely related to 0. crispum. It has rather small pseudo- 

 bulbs, which are oblong blunt compressed and furrowed, 

 and terminated by a solitary lanceolate acute leathery dark 

 green leaf. The scape, which is radical, often springing from
