THE BOOK OF GARDENING. 



Trichopilia is an interesting genus of plants. The T. suavis 

 section, which are the most popular, are best suited when g«own 

 in pans suspended from the roof of the cool intermediate 

 house ; they require the usual compost of peat and moss as 

 potting material, with a liberal supply of moisture throughout 

 the year. 



Zygopetalum. — A lovely genus of Orchids. One of the species 

 is usually found in places growing admirably with other plants 

 where there is no pretension to cultivate Orchids, and this is 

 often a source of envy to the Orchid specialist. Zygopetalums,

with but few exceptions, thrive under cool intermediate treat- 

 ment. The potting material should consist of fibrous peat, 

 a little loam, and chopped sphagnum. The pots used should 

 be drained to two-thirds their depth, as the plants require 

 a liberal supply of moisture during the greater part of the 

 year. Z. Sedeni (Fig. 392) is a very rare and desirable 

 hybrid, derived from the intercrossing of Z. Mackaai and 

 Z. maxillare. 



There are many other species and varieties that might 

 have been included amongst the intermediate Orchids, but 

 as space is a consideration I have noted only those which 

 I consider most suitable for the amateur and for a general 

 collection. Others will be found in the "Appendix."
