PHALACRjEA CCELESTlNA, Regel: Ageratum conyzoides. 



PHAL^NOPSIS (Greek, moth-like; suggested by 

 the large white flowers of some species). Orchidacex. 

 This genus, called by Lindley "the grandest of all 

 orchids," contains some of the most useful species to 

 be found in the orchid family; warmhouse. 



Of monopodial growth, having short sts. which 

 increase slowly in length: Ivs. few, thick, leathery, often 

 mottled: infl. a raceme or panicle, large, or not longer 

 than the Ivs. ; sepals spreading, the lateral ones more or 

 less united with the base of the column; petals about as 

 large as the sepals or very much broader; labellum vari- 

 ously shaped but united with the base of the column. 

 About 50 species natives of the hot regions of India 

 and the Malay Archipelago, growing on trunks of trees 

 and sides of rocks under conditions of high temperature 

 and great moisture. The fls. are remarkably beautiful 

 in form and color. Those of the larger species are borne 

 in graceful drooping panicles on which they usually all 

 face in one direction. 



As all phalaenopsis are natives of the most tropical 

 regions of the globe, it is essential that they be well 

 supplied with heat and moisture, particularly during 

 the growing season, from March to October. Care 

 should be taken to avoid direct draught on the plants, 

 but air should be admitted on all possible occasions. 

 This is absolutely necessary to keep the plants in perfect 

 condition. During bright sunshine the plants should 

 be shaded, but given all the light possible to insure 

 good tough ripe foliage by autumn, and large branch- 

 ing flower-spikes may be expected in the flowering sea- 

 son. A close moist atmosphere will grow large soft foli- 

 age, but small flower-spikes usually result. Plants may 

 be grown suspended from the roof, not too near the 

 glass, or on benches, in pots, in baskets, in pans, or on
