THE ORCHID REVIEW. 269 



Odontoglossum crispum gives us the most varieties for the commercial 

 market, and is, therefore, the best. I am sorry to say that this noble species 

 has often been found difficult to handle. It grows well on a very high 

 elevation of the Andes, where the atmosphere is cool and damp, and seldom 

 rises above 6o° Fahr. Thus its natural climate is hard to imitate, and the 

 plants, therefore, suffer from our hot summers. It is clear that a special 

 house should be provided for this species. Face the house north, shade it 

 from the sun, keep it moist, with a low temperature, and your plants will 

 succeed admirably. O. grande is another good kind, with very large yellow 

 and brown flowers. The market for this Odontoglot is, as yet, limited 

 to a certain extent, but it is worthy of culture for variety. Miltonia Roezlii 

 is a very desirable sort, for which good prices are obtained. It wants lots 

 of moisture about the roots, and a warmer temperature than the majority 

 of its relations. The flowers are very large and effective, almost pure white, 

 with purple and yellow towards the bottom. 



Oncidium varicosum and its varieties are all good fall flowering kinds. 

 The flowers are produced on long, overhanging branching shoots, not 

 unlike a gigantic Adiantum frond. O. splendidum and O. tigrinum are 

 valuable for the late winter months, with their large yellow and brown 

 flowers. They will, like O. varicosum, do well with the Cattleyas during 

 their growing period, but want a long rest in a cool house when their 

 flowering period is over. 



Cypripediums are easier to propagate by division and seeds than mos 

 other Orchids. We have at the present time only a few varieties of 

 commercial value. C. insigne (one of the best), C. barbatum, C. callosum, 

 C. Boxallii, C. villosum, and C. Lawrenceanum are among the best. 

 Here is a great field open for the thoughtful and skilful hybridiser, who 

 may be sure of success. The belief is based on results obtained in hybrids 

 like C. X Harrisianum, C. X Leeanum superbum, C. X Morgani<e, C. X 

 Clinkaberryanum, and lots of others. Some of these hybrids are costly in 

 themselves, but nevertheless can always be had at a moderate price, and 

 after a few years hundreds of growths may be obtained at little trouble and 

 small outlay. 



A noted Orchid expert once exclaimed: "Just fancy a house full of 

 Cypripedium X Morgani« " — which is a cross between C. superbiens and 

 C. Stonei. Just think of it, with its long, robust stems, each one crowned 

 with three or four indescribably beautiful flowers, and that will give us 

 some idea of what might be accomplished with this more than interesting 

 genus. 



Although most of our Orchids, with a very few exceptions, may be 

 grown in almost any greenhouse, it is claimed by Orchid experts that a 

 full span house, from the north to the south, is best. It should be
