have its anthers cut out as soon as possible after the opening of 
the flower, and after standing until the stigma is ripe, (to de¬ 
termine which is the only difficult part of the operation,) the 
pollen of the flower it is desired to cross with is then applied by 
means of a fine camel-hair brush, observing to lay it evenly over 
the whole surface of the stigma. To prevent accidental impreg¬ 
nation, which is very likely to occur, from wind, insects, &c., it 
is always necessary to protect the flower that is to bear the 
seed with a covering of thin gauze, or some such material, 
unless it is standing under glass, and in a situation not subject 
to roving visits from bees, butterflies, &c. 
Our present illustration, G. rosea alba , is an hybrid obtained 
by Mr. Rendle, Nurseryman, of Plymouth, from seed of Candida 
impregnated with the pollen of rubra; its beautiful intermediate 
colour at once proclaims its origin, and we have no doubt it 
will speedily become a favourite. This is one of the very 
few instances of any other than speciosa being thought of as a 
parent for the future progeny; and the success attending its 
adoption must have great weight in determining future attempts 
of the same kind. 
[For a detailed account of the culture of this handsome and 
interesting genus we must refer our readers to page 245 of Vol.

170. Grammatopliyllum floribundum. Plant pseudo-bulbous, bulbs seven 
inches long, and better than three inches broad, rather flat, and of a shining 
green colour ; leaves mostly in fives, about eighteen inches long and two inches 
broad, a little waved; the raceme half-pendent, two feet long, and produced 
from the base of the bulb ; flowers verticillate along the raceme, the colour 
greenish yellow, veined, and blotched with brown. This species is worth 
cultivation : it requires a strong heat and plenty of water during its growth ; 
it may be grown in a pot, in a mixture of sphagnum, turfy peat, rotten wood, 
and a little charcoal, with a temperature of 70°. — d Native of Pulo 
Dinding. 
171. Grammatopliyllum speci'osum. This plant is much similar in growth 
to the above, but its flowers are more showy, from which circumstance its 
specific name is derived : it may be treated in the same manner. These are 
the only two species that this genus is composed of; but a variety has lately 
come out, called G. multiflorum tigrinum, the colour of which is nearly as 
rich as that of Oncidium papilio : it requires the same treatment as the others. 
This genus should have a particularly good drainage, as the roots are liable
