valleys where the climatic conditions are hot and moist for the greater part of the 
year. It does not require the same heat as does Amesianum or Medusae, and can 
readily be grown in a fairly warm bushhouse both in Brisbane and the North. In 
Sydney it will probably be desirable to grow it in a glasshouse, particularly in the 
Winter months. The general cultural treatment is as already prescribed for other 
members of the genus. 
CIRRHOPETALUM ROBUSTUM. Native of New Guinea. 
A large growing species found in the valleys of Central Papua and New Guinea. 
Pseudobulbs large and rectangular—leaves thick and leathery, about a foot long 
and 34 to § inches wide. Flower scape thick, bearing a head or umbel of 7 to 13 
flowers. Sepals and petals—yellowish, tinged with purple—lip deep reddish purple. 
This plant needs warm, moist conditions and will require glasshouse treatment in 
Sydney and Brisbane (with heat desirable in the Winter), but in North Queens- 
land should do well enough in the warmest and moistest part of the bushhouse. 
Copious watering is necessary in the Summer, and even in Winter it should not be 
permitted to dry right out. 
There are a number of other species, but the only ones worth cultivating are rare 
and unlikely to be met with, so I have not included them in this table. 
COCHLIODA 
A genus of interesting and beautiful epiphytical orchids allied to the Odontoglos- 
sums and to the Oncidiums. They are not frequently grown in Australia, but a 
number of growers have one or two of the bi-generic hybrids between Cochlioda 
and Odontoglossum known as Odontiodas. 
The Cochliodas are natives of the Andes of Peru at an elevation of about 8000 
feet, and they therefore require cool treatment at all times. This feature militates 
against their being easily imported, except in the form of well established plants 
properly dried off for shipment. It is desirable also that shipment be made at such 
times as will allow their travelling to be done during the coolest months of the year. 
They can be set in pots, but are better suited by hanging teak baskets. A compost 
of polypodium fibre or todea with a little sphagnum moss is suitable, but a good 
alternative compost is one composed of two parts chopped osmunda fibre, one part 
chopped sphagnum and one part good leaf-mould—not fine powder, but rather 
coarse—with a little sharp sand—the compound to be well mixed and pressed 
firmly about the plant. 
Cochliodas should be grown in the coolest part of the bushhouse. They like plenty 
of light, but our Queensland sun’s rays are rather too fierce to allow them to come 
into direct contact with the plant. They therefore require shaded conditions. 
The climatic conditions of Peru are rather varied. The low lying lands between 
the Andes and the coast (Pacific) are arid. The eastern slopes of the Andes have
