frequently more ; the seed is sown in light fibrous peat, and the 
pot plunged about half its depth into the water. Three weeks 
is the usual period required for the appearance of the plants 
above the surface of the soil, when they are immediately re¬ 
moved to other pots, and placed in a genial hotbed; and after 
another three weeks of attention in this place are gradually 
hardened, when they are capable of enduring almost any treat¬ 
ment ; for, however difficult in the first instance to raise, there 
is scarce another plant so manageable in after-growth (except 
as regards dwarfing), and certainly none which repay the 
culturist with more specious or sweetly-scented flowers, than 
does the Martynia fragrans. Why do not gardeners turn their 
attention to the hybridizing of this genus ?

LIST OF ORCHIDE7E. 
( Concluded from p. 81.) 
306. Oncidium raniferum. Plant pseudo-bulbous; bulbs one inch long, 
tapering a little towards the apex ; leaves in pairs, three inches long and 
narrow ; the flowers are produced on a spike, six inches long, branched, they 
are yellow; the sepals and petals being spotted with brown ; the labellum is 
also marked with brown; the tubercules or crest have the appearance of a 
frog crouching, hence the specific name. A very singular little species, 
requiring to be grown upon a small billet of wood, with a little moss 
fastened about it; it may also be grown in small pots, with a compost of 
turfy peat, a little sphagnum, and very small potsherds ; a very little water 
will be required during its growth, and scarcely any when resting, tem¬ 
perature 65° to 70°. — Native of Brazil . 
307. Oncidium Russellianum. Plant pseudo-bulbous; leaves in pairs; 
flowers produced on a long spike; sepals and petals brown, intermixed with 
purple; labellum purple. This rare and lovely species is decidedly distinct 
from any other of the tribe ; the flowers are very large; it requires pot culti¬ 
vation, in a compost of turfy peat and small potsherds, with a liberal supply 
of water if a free drainage is underneath (which I particularly advise), and 
a temperature from 65° to 70°. — Native of Brazil. 
308. Phalccnopsis amabilis. Plant destitute of pseudo-bulbs, but composed 
of a number of leaves 5 inches long, and about 3 inches broad, oblong ; 
flower-spike 2 feet long; flowers paniculate, and of a beautiful dazzling 
white ; sepals a little more than 1 inch long, and half an inch broad, oblong, 
obtuse; petals nearly 2 inches long, and the same in breadth, suborbiculate, 
unguiculate ; labellum three-lobed, the outer lobes ovate, obtuse, incurved ; 
base lutescent; the middle lobe has a pair of horns resembling the antennas of
