indeed, the frost has already ruptured their tissue; the effects 
of five or six degrees may thus be expeHed ; though a know¬ 
ledge of this must not serve as an excuse for inattention^ nor 
must the cultivator imagine, that because there is a remedy for 
slight cases that the plants may be left to themselves through a 
cold night, for it may likely enough happen that they get an 
over-dose, from which no art can relieve them. 
Another method is sometimes employed, that of dashing 
cold water through a syringe over the parts affected : this, how¬ 
ever, is notan advisable practice, for though it remove the frost, 
the plants frequently suffer from the effects of the moisture; it 
may, however, be adopted where shading in not* possible. It 
must be understood that it is absolutely necessary to the success 
of either that the application be made on the earliest dis¬ 
covery of the accident, for it would be quite useless to attempt 
the recovery of the plants an hour after the sun s rays have 
reached them. ■— Ed.

284. Oncidium lacerum. This species has much the habit of 0. longifo - 
Hum, but the flowers are more dense, as in O. ascendens. It also requires 
the same treatment and temperature.— Native of Demerara. 
285. Oncidium papilio. (Butterfly-like.) Plant pseudo-bulbous ; bulbs 
3 inches long, and the same in breadth, rather flat, angles sharp ; leaves 
single, lanceolate ovate, colour dark purplish green, spotted with pale green; 
flower-spike 3 feet long, and slender, lasting for years ; flowers solitary, 
sepals and petals spotted and barred with orange; the former are like the 
horns or antenna? of the insect, the latter are like wings; the column bears a 
striking resemblance to the head; labellum yellow, spotted and barred with 
purple? This species seems to differ in a great measure from the other 
members of the genus it belongs to, and it remains a doubt whether it may 
not more appropriately form part of the genus Odontoglossum. It requires 
pot cultivation, with a free drainage and a compost of turfy peat, and 
sphagnum, with some small potsherds mixed together, and to be sparingly 
watered at any time. Temperature from 65° to 70°. — Native of Trinidad. 
286. Oncidium ampliatum, var. major. Plant pseudo-bulbous; bulbs 2 
inches long, ovate ; leaves sometimes in pairs, but generally single, 8 inches 
long and 3 inches broad; flower-spike 2 feet long, branched; the sepals and 
petals of the flowers are large and showy, yellow spotted with red; labellum 
yellow without any spots. This species may be either grown on a billet of 
wood covered with sphagnum, or in a pot with plenty of drainage and a mix¬ 
ture of turfy peat, sphagnum, and small potsherds, with a liberal supply of 
water while growing, and a mean temperature of 65°. — Native of Trinidad.
