and furrowed, a foot or more in length—topped by a single, leathery, dark green 
leaf—rather glossy. Scapes carry from two to five flowers which range from 6 
inches to 84 inches in width. Colour varies considerably, but usually sepals and 
petals range from light pink to deep rose. Labellum beautifully fringed and 
crinkled at the edge, large and spreading, the basic colour being the same as the 
petals, but suffused with rich violet, with purple veins, bordered with lilac and 
with a rich orange stain at the base. 
Bushhouse treatment will suit this species, particularly in the warmer parts of 
Brisbane and the North. A well defined resting period is necessary for the pro- 
duction of flowers and light airy conditions are desirable. 
CATTLEYA PERCIVALIANA. Native of Venezuela. 
This very beautiful species is found near Merida on the slopes of the Merida range 
at an altitude of from 4000 to 6000 feet (and occasionally higher up the range). 
It is usually found on the taller forest trees and occasionally on exposed rocks and 
cliffs. The stems are from 7 to 15 inches in length, prominently furrowed, 
and usually slightly thicker in the middle than at either end. Flowers smaller 
than those of Mossiae which they resemble in shape, but are richer in colour tones 
—the lip being particularly striking, with a well fringed margin of rose pink in 
contrast with the rich magenta-crimson of the front lobe. The throat is a beauti- 
ful, rich yellow lined with maroon and purple. It flowers in midwinter, which 
adds to its value in a collection. In its natural place of growth it has a temperature 
range from 49° mean minimum in midwinter to a maximum of 88° in mid- 
summer. It is therefore particularly suited for bushhouse treatment in Brisbane 
(so far as temperature is concerned) and in North Queensland. It likes plenty of 
light and good air circulation, but requires less water throughout the year than 
almost any other species of Cattleya. The rainfall data as recorded for Merida is:—

The plant flowers during December and January (in Venezuela) and then rests 
until the beginning of April when the commencement of the seasonal rains 
starts it into growth again. The rainfall averages from Brisbane are considerably 
higher than is the case at Merida. Thus, if the Winter is wet it will be desirable 
to move the plant under shelter so that its period of rest may be uninterrupted. 
Hybrids carrying a large amount of Percivaliana strain will probably benefit by 
similar treatment. 
CATTLEYA SKINNERI. Native of Guatemala. 
Found in the dense, tropical rain forests high up in the trees. This species requires 
rather warmer and moister atmospheric conditions than most of the Cattleya
