convolute around it, the middle lobe crisped and terminated by 
a large mucro, downy within: the colour yellow, with streaks 
of orange-red, and there are three lamella in the centre. Column 
winged above and dentate at the apex. Anther-case hairy, 
bifid. Pollen-masses four, unequal, all of them bifid. W. J. H. 
Cu.t. Before we can cultivate certain plants with success, 
we require some knowledge of the climates in which they 
grow, so as to adapt the means we have in our power as 
far as possible to meet their several peculiarities. This 
plant is said to be a native of the Island of Bourbon, 
situated within the southern tropic, and distinguished by a moist 
climate, caused by the periodical rains, which fall twice a 
year; also by the daily land and sea breezes, the former 
wafting cold vapours from the high mountains of the interior, 
which are said to be covered with snow during several months 
of the year; and the latter bringing fogs from the ocean. 
Now, although we know this to be the general character of the 
climate, we are still unacquainted with the nature of the locality 
of this plant, which may be subjected to many local influences ; 
and our want of this precise knowledge may to a'certain extent be 
the cause of its slow growth with us. It has been kept in the 
warm division of the Orchideous house, potted in turfy peat— 
the usual precautions being taken to prevent the soil from be- 
coming stagnant. J. 8.
