was too warm for the successful cultivation of Odontoglossums, the plants under 
the care of Mr. Vincent prove such not to be the case, as at Gouville these 
plants are in the finest possible condition. 
Odontoglossum cuspidatum xanthoglossum is a splendid compact-growing evergreen 
plant, having pseudobulbs and leaves of a rich dark green hue; its spikes are thrown 
up after growth is completed, the raceme being many flowered, and drooping from the 
weight of its flowers, which are very brilliantly coloured. The blooms are large, 
and the sepals and petals are rich golden yellow, blotched and barred with chestnut- 
brown; the lip is somewhat pandurate, cuspidate, the edges waved and _ toothed, 
yellow, blotched with a large spot of reddish brown at the base. It is a very 
brilliant and showy variety, especially when mixed with the white flowers of such 
kinds as O. Alexandre, O. Pescatorei and others, and when so grouped it is very 
effective. It blooms during the months of March and April, and lasts fully six 
weeks in perfection. 
The requirements of this Odontoglossum are identical with others from the cool 
regions of U.S. of Colombia, and of which we have so frequently given details in these 
pages. One great feature to be observed in the cultivation of these plants is to 
keep them free from all insects, which, if not well searched for, will infest cool 
growing Orchids; however, they having a lower temperature and moister atmosphere than 
the warm house species, are not so liable to become infested with insects, but there 
is a small-shelled snail (Helix alliaria) which is introduced with the sphagnum moss, 
and ‘small slugs which have the same origin, that acquire a rabid taste for the 
young spikes of bloom as they appear, and unless they are rigidly kept down will 
be a source of great annoyance by so destroying the blossoms. Full instructions 
for the destruction of insects and all pests which infest the Orchid plants may be 
found in the sixth edition of Williams’ Orchid-Growers’ Manual, p- 79, and if the details 
there recounted are carefully studied, and the requisite remedies adopted, there will 
be little fear of these insects becoming troublesome; but if the work is done in a 
careless and negligent manner they will soon. Se eie a source of regret and 
lamentation.
