MAXILLARIA 



rim of the pot when finisheil. Maxillarias delight in a 

 cool, moist, shaded location at all seasons where the 

 winter temperature will not exceed 58° F. by night and 

 not over 60° or 05° by day. During summer they must 

 be grown as cool as possible with ventilation at all sea- 

 sons when admissible, especially in wet, heavy weather. 

 Water should be given in abundance while the plants 

 are growing and not too sparingly when at rest, as the 

 plants are subject to spot if kept too dry. Weak liquid 

 cow manure is beneficial occasionally during root action. 

 Maxillaria has two recognized horticultural groups or 

 sections; viz., caulescent and stemless. The caulescent 

 section embraces J/. /eji«i7o?iVi,il/'.!'ffria6i7is and kindred 

 species, having scandent rhizomes and often obscure 

 liowers. These should all be grown under pot culture 

 and afforded supports to climb on, such as small cylin- 

 ders or rafts of open woodwork with a little compost 

 worked in the openings, or Osmunda rhizomes supported 

 obliquely in the pots to which the plants can attach 

 themselves as they grow upward, and thus be supplied 

 with moisture for the young roots. To the stemless 

 .section belong those with clustered pseudobulbs, as 

 M. fiiscata, M. (iraiidiflora, M. liitto-albri, 31. pictii, M. 

 Snmleriiina and M. renusla. Some of these have very 

 showy flowers. Nearly all do best under pot-culture. 

 M. Sftnderiana and others are exceptions, however, 

 and grow best under basket culture, not too much com- 

 post and an airy position. Demand for Maxillarias not 

 being great, the market usually relies on new importa- 

 tions, but stock may also be increased by division be- 

 tween the pseudobulbs as the plants start new action.
