develop blue-black marks. In Australia it is found over such a wide range of clim- 
atic conditions that it would appear to grow anywhere. It does quite well planted 
in an ordinary garden border. If potted it requires much less leaf-mould and dung 
than the exotic species—in fact, too rich a compost encourages vigorous growth 
at the expense of flowers. Ordinary bushhouse treatment is all that it needs and 
it does not require a great deal of water at any time, though, like most other 
orchids, it needs more in the Summer than in Winter. 
CALANTHE VESTITA. A Native of Moulmein. 
Probably the finest species generally grown. The pseudobulbs are large and silvery, 
and apple-shaped. The leaves are large, lanceolate, bright green and much plaited. 
The flowers are creamy white, generally with a yellow blotch in the throat. 
They are much larger than veratrifolia. The varieties Fournierii (shades of pink 
and rose), luteo-oculata (yellow blotch on lip), rubro-oculata (crimson blotch 
in throat), Regnier? (with rosy blush all over) are all fine variations from the 
type. 
They require exactly the same treatment as prescribed for Calanthe rosea (above). 
CATASETUM 
This genus of epiphytes has a very large number of species, but very few of them 
are considered worthy of cultivation. 
Natives of Central and South America, they grow in the forests on the lower 
branches of trees, generally where they can get plenty of light. They need 
ample heat and water during the growing period. In the resting season a lower 
temperature and practically no water should be provided. They can be grown on 
blocks, but it is preferable to pot them in baskets or pots in a compost consist- 
ing of three parts crocks and charcoal and one part fibrous peat or todea or 
osmunda or well teazed cocoanut fibre. The following are the most popular 
species: — 
CATASETUM MACROCARPUM. Native of Colombia, Ecuador and Brazil. 
Similar in growth to pileatum. Flowers yellow-green spotted with brownish 
purple, lip rich orange. About 4 inches across. Cultural requirements as for 
pileatum. 
CATASETUM PILEATUM (syn: Catastetum Bungerothii). Native of Ecuador. 
One of the most notable species. Pseudobulbs stout and fusiform and about 9 
inches long. Leaves broad at base, fining to a point at the apex, prominently 
veined and deep green in colour. Usually three to four leaves remain on the stem 
at one time. Flower scapes grow from the base of stems, each stem producing 
50 .
