their bases. Very fragrant. Blooms in late Summer or Autumn, and lasts for 
some weeks. 
(Syn. Warrea Wailesiana and Zygopetalum Wailesianum.) 
WARSCEWICZELLA WENDLANDII. Native of Costa Rica. 
One of the best species, with tufted, oblong, strap-shaped leaves. Flower spikes 
carry a single flower between 4 and 5 inches across, in good specimens. Sepals and 
petals lanceolate, twisted and white. Lip rather heart-shaped with a recurved 
apex, white with a violet-purple blotch marked with numerous dark purple lines 
lengthwise. Flowers in early Autumn and lasts two weeks or more. 
Var. discolor—Very fragrant. Sepals and petals yellowish-green. Lip much 
crisped at the margins, white with a violet blotch in the centre. 
ZYGOPETALUM and ALLIED GENERA 
An epiphytical genus of orchids of a score or more species whose flowers are 
extremely attractive but which has been somewhat neglected by Australian 
growers. However, quite a number of growers have plants of various species, 
generally Zyg. Mackayi and its varieties, or Zyg. intermedium, and it is probable 
that from time to time opportunity will be afforded of increasing their holdings. 
I have noticed in regard to this genus that the plants take some time before they 
become acclimatised. They usually go back very considerably for the first year 
or two after their acquisition, but when they have become established they make 
rapid growth. They are all natives of tropical Central and South America, but 
grow at considerable altitude, so that they do not flourish easily in a hot, humid 
atmosphere, preferring the warm but rather rarefied air of tropical highlands. 
The temperature range in Brisbane quite closely approximates that of their natural 
habitats, but our air is rather “heavy” for them. Nevertheless under bushhouse 
treatment in Brisbane and northwards they will eventually grow. In Sydney a 
cool glasshouse is most suitable for them. Worried by their failure to commence 
growth quickly, I tried many varieties of compost for them, but have come to 
the conclusion that the potting material is of secondary importance. I find that 
a mixture of half and half osmunda and polypodium fibres is as satisfactory 
as can be had; but staghorn peat or todea can be substituted for the polypodium 
without detriment. Copious water is essential during the growing period, but 
care must be taken to prevent any moisture lying in the young growths, as they 
are particularly susceptible to ““damping off.” In the resting period a minimum of 
applied water is necessary, but the plants should not be allowed to “dry out,” 
sufficient liquid being given them to keep the compost about the roots slightly 
damp. The Zygopetalums like a reasonable amount of light, but should be kept
