362 THE ORCHID REVIEW. 
Orchids of Australia, which are well worth growing, the remarkable Disas 
and other genera of South Africa, many of which have never been seen in 
cultivation, and the many beautiful Indian kinds. “A Century of Indian 
Orchids,” by Sir Joseph Hooker, and “ The Orchids of the Sikkim Hima- 
laya,” by Sir George King and Mr. Robert Pantling, are perfect mines of 
wealth for the seeker after curious, beautiful, and little, known Orchids. 
As an example of the work that might be done by residents in foreign 
countries, the author mentions Mr. Lehmann, who during a quarter of a 
century of travels in the Andes of Colombia and Ecuador, has sent home 
many rare ‘and inconspicuous . Orchids, including Sievkingia and Trevoria, 
the pretty Polycycnis Lehmanni, and many others. 
Few groups of plants produce such remarkable and interesting flowers 
as the quaint Catasetums, Mormodes, Cycnoches, and Coryanthes. Of the 
curious distinctiveness of their flowers, the wonderful apparatus for securing 
fertilization by insect agency, &c., a great deal might be written. 
Masdevallias are now out of fashion, but, for beauty of colour, grace of 
form, and striking development, yield to few other genera, and some of the 
dwarf species when well cultivated are lovely little subjects. M. muscosais 
remarkable for its mossy peduncles and the extraordinary sensitiveness of 
its labellum, which closes on the slightest touch of a small tubercle near 
its base, and then opens again after the lapse of about half an hour—an 
arrangement evidently connected with the fertilization of the flower, as the 
effect would be to imprison an insect that had crawled over the tubercle. 
As an example ef vegetable mechanism, interesting to everybody, nothing 
could be more interesting than this. M. deorsa has the unusual habit of 
growing head downwards, hence the name. 
Of the allied genus, Pleurothallis, nearly 400 species are known to science, 
and of those in cultivation P. Roezlii has very richly coloured flowers when 
held up to the light, while P. Grobyi and P. ornata are examples of many 
which are of singular form and gem-like beauty. The Restrepias are most 
attractive floral objects, and there are numerous other genera, containing 
many interesting species, which the short time at his disposal only allowed 
him to mention by name. 
As regards cultivation, some of the Orchids referred to were at present 
difficult subjects, but that was all the more reason for persevering with their 
cultivation. It was years before the cultivation of many Orchids which 
now grow to perfection in our houses was understood. But the smaller and 
less showy kinds present no greater difficulties than their larger and more 
pretentious brethren, and he hoped to see them more generally cultivated, 
The illustrations comprise the following species :—Angrecum Sanderi- 
anum, Bulbophyllum barbigerum, B. Dayanum, B. patens, B. tremulum, 
Cirrhopetalum fimbriatum, C. Roxburghii, Masdevallia Estrade, M.-
