EPIDENDRUM 



perature may range from 50 to 55 Fahr. at night, and 

 a few degrees higher during the day. They are increased 

 by division. This should take place as the plants start 

 growth action in early spring, allowing at least three 

 pseudobulbs to each piece. 



Section II. Encyclium, of which E. atropurpureum , 

 E. nemorale and E. prismatocarpum are good examples, 

 may be grown either in pots or baskets in equal parts 

 clean peat fiber and live chopped sphagnum, with a 

 liberal amount of drainage, and excepting E. vitellinum, 

 which must be grown cool, they require a moist, sunny 

 location with a winter temperature of 58 to 65 Fahr. 

 by night and several degrees advance during the day. 

 In February and March, many species will start root or 

 growth action; such as need it should then be repotted 

 or top-dressed, as occasion requires. The temperature 

 should be increased several degrees, and a greater 

 amount of water be allowed with frequent overhead 

 syringing on bright days. Ventilation should be given 

 whenever the weather will permit, to keep the young 

 growths from damping-off and the atmosphere active; 

 at this time the plants will need light shading to pre- 

 vent sun-burning. The stock is increased by cutting 

 nearly through the rhizome 3 or 4 bulbs behind the lead, 

 when starting action ; this will generally cause the 

 latent eyes to grow, but the pieces should not be re- 

 moved until the new growth is well advanced. 



Section ///. Aulizeum includes such species as E. 

 ciliare, JE. cochleatum, etc., the several requirements 

 being identical with the preceding. 



Section IV. Euepidendrum. These are mostly tall 

 growing reed-like species, of which E, evectum and 

 JE. radicans afford good illustrations. They are best 

 adapted for pot culture. The pots should be two-thirds 

 filled with drainage and the compost consisting of 

 about equal parts peat fiber and live sphagnum, well 

 mixed pressed in firmly about the roots, leaving the 

 surface raised a little above the rim in the center when 

 finished, to shed off surplus water. While the plants are 

 growing they require a shaded, moist location, a day 

 temperature of about 75 Fahr., with 5 or 10 degrees 

 less at night. They should not be kept too wet at the 

 roots, but overhead syringing in bright weather is very 

 beneficial. While at rest, in winter the temperature 

 should be modified 10 degrees and a more sunny loca- 

 tion be given, with less frequent syringing, enough only 

 to keep the canes or pseudobulbs in sound condition. 

 Young plants often form in the axils of the upper leaves, 

 and on the old flower stems it is best to let these young 

 plants remain until they start their second growth, as 

 they can be more safely removed at that time. 



Section F. Psilanthemum contains but one species, 

 E. Stamfordianum, which requires the same general 

 treatment as those in Section II. ROBERT M. GREY.
