ODONTOGLOSSUM. 357

during April and May. We have seen a form of it with 
flowers which measured 5in. across. The species was dis- 
covered in 1847, in the oak forests of New Granada, at 
an elevation of about S8oooft., whence it was introduced 
about 1851. The specific name commemorates a French 
orchidologist, M. Pescatore, whose collection was at one 
time considered the finest in Europe; he died in 1855. 
Syn. O. nobile. 
Bateman’s Monograph, t. 5. 
The varieties of this species are numerous, some being of 
exceptional beauty and value. The best of them are here 
given: 
Var. Veitchtanum.—Flowers larger than in the ordinary 
forms, very symmetrical, and irregularly blotched with 
rich magenta-purple. 
Var. Schrederianum is similar to var. Veitchianum. 
Var. Vervaetianum is another richly-marked kind. 
There is considerable variation in the markings of the 
flowers, some being tinged with rose or purple, others 
streaked, whilst in the number of spots the range is from 
a solitary one on the lip to numerous blotches all over 
the segments. All these should be cultivated in the same 
manner as O. crispum. 
0. polyxanthum.—A robust and handsome kind, similar 
to O. Hallii in pseudo-bulbs and foliage. Flower-spikes 
2ft. long, arching, and branched; flowers 3in. across; 
sepals and petals broad, acute at the points, lemon-yellow, 
with red-brown blotches; lip oblong, with a crisped edge, 
red-brown, bordered with yellow; column white, with 
brown blotches. A native of Ecuador, whence it was in- 
troduced in 1878. It flowers in April and May, and 
requires cool, moist treatment all the year round.
