CYCNOCHES CHLOROCHILON. Native of British Guiana. 
This orchid is sometimes referred to as ‘“The Swan Orchid,” from the fancied re- 
semblance to a swan’s neck and head in the long slender column—in fact, the 
genus gets its name from this fact. The pseudobulbs are long (about 12 inches) 
and fleshy, and carry some four broad and prominently ribbed leaves about 10 to 
12 inches in length. The flowers are produced on rather short curving scapes, and 
are about five inches across. There is considerable variation in the colour of these, 
but a shade of yellowish-green is usual, and the lip ivory white with a dark olive 
green shiny blotch in the centre. The column is long and curved and swollen into 
a prominent round knob at the apex. The number of flowers varies from three to 
about ten on each scape. They last for some three weeks in midsummer. 
Cycnockes chlorockilon is found in the thick jungles on the slopes of the Roraima 
Mountain, near the borders of British Guiana, Brazil and Venezuela. This species 
requires warmer treatment than does aureum, and also rather more water in the 
growing period. A warm bushhouse will serve in the warmer parts of Brisbane, but, 
in the cooler parts and southwards, glasshouse treatment will be desirable, particu- 
larly in the Winter months when the plant must be kept as dry as possible, with- 
out allowing the pseudobulbs to shrivel. Given suitable conditions this is the eas- 
iest species to grow and it is a very free bloomer. 
CYCNOCHES LODDIGESII. Native of Dutch Guiana. 
Pseudobulbs short and spindle-shaped, sheathed by the bases of the leaves which 
appear in two parallel rows and are broad and pointed. The racemes come from 
the top of the stem and usually carry from six to eight large, fragrant flowers about 
4 inches in width. The flower has sepals and petals of a deep brownish green, the 
sepals with chocolate spots. The lip is trowel-shaped, and is white (sometimes with 
a pale pink flush) spotted with blood-red dots. This species occasionally produces 
two very distinct racemes of flowers from the one pseudobulb at the same time. 
The flowers appear in early Autumn—lIast for about three weeks if kept cool and 
dry. 
Treatment as for C. chlorochilon. 
CYCNOCHES VENTRICOSUM. Native of Guatemala. 
An interesting species which occasionally astounds its growers by producing two 
totally different types of flowers—so diverse that one can hardly believe they are 
produced by the same plant. Pseudobulbs tall and fleshy, and sheathed with the 
bases of the membraneous, broad pointed leaves. Usually two racemes are pro- 
duced at a time, these proceeding from the axils of the top leaves on the latest 
matured stems. As a rule, each spike carries five flowers, having broad pointed 
sepals of pale green, the petals being the same colour but about twice as broad 
with a downward curve. The lip is white and has a black callosity on the claw 
that connects it with the column. It blooms in midsummer and early Autumn, 
and the flowers last about three weeks. Occasionally instead of, and sometimes 
concurrent with, the usual flowers, it sends forth a long drooping raceme carrying
