4 deg. to about latitude 8 deg. N. It grows on trees and generally abounds near streams in sunny positions, where 
its stems are stouter and shorter, and bloom more freely than the lanky individuals found in more damp and shaded 
situations. 
The culture of the labiata section of Cattleyas must be placed under two heads, viz., those producing their flowers 
from partly made up or unfinished bulbs, and those that bloom from fully ripened aud finished bulbs. Under the 
first heading come Cattleya labiata Warnerii, Gaskelliana, Dowiana (and its sub-species aurea), speciosissima, and 
Warscewiczii. These should be kept moist and fully growing until their bulbs are made up, that is to say, they 
must be kept watered for several months after flowering, and, as soon as the bulbs are quite ripe, water must be withheld 
for four weeks, or even longer. Into the second section fall Cattleya labiata Trianzei, Mendelii, Mossiae, Lawrenceana, 
Schrédere, and Percivaliana. These should be kept moist and well-watered until the bulbs are fully matured, then 
kept slightly drier until about four weeks before their proper period of flowering arrives, and, during the four weeks 
before their flowers expand, very moist, in order that the plants may develop fine large blooms. After flowering, withhold 
water gradually for four weeks, then altogether for fully a month, when again the resting period should be considered at 
an end and the culture taken fully in hand. Cattleya Warscewiczii requires a rather sunny and very light position. 
During sunheat the temperature may rise to 80 deg. F. The resting period of this species should be kept longer than 
that of any other of the labiata group.

It is interesting to note that in the above group some are extremely variable—C. Mossix, C. Trianzei, C. Gaskelliana, 
C. Mendelii, to wit,—while others, although variable also, are more restricted in form and colour. The question of colour 
is an important one and seems geological or chemical rather than climatic, and yet geologists have failed to tell us why 
Cattleyas are white, yellow, or bright rose-purple on the same geological formation. The chemistry of flower colour and 
odour is an exceedingly subtle thing, and as a subject of research has been too long ignored. Most amateurs are satisfied 
with the actual facts, but it is as well to bear in mind that nothing exists except for a purpose, and that no effects in 
nature are evident without some predisposing cause.
