EPIDENDRUM 



EPIDENDRUM 



vent sun-burning. The stock is increased by cutting 

 nearly through the rhizome three or four bulbs behind 

 the lead, when starting action ; this will generally cause 

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

 removed until the new growth is well advanced. 



Section III. AULIZEUM includes such species as E. 

 ciliare, E. cochleatum, and the like, the several require- 

 ments being identical with the preceding. 



Section IV. EUEPIDENDRUM. These are mostly tall- 

 growing species, some reed-like as in E. evectum, and 

 others rambling in an irregular way, producing aerial 

 roots along the stems as they grow; a good example of 

 this is seen in E. radicans. All are best grown in pots 

 and placed near a partition or end of a greenhouse 

 where support may be given as the growth advances. 

 There is, in fact, no better example of an epiphyte than 

 E. radicans, the roots often attaining several feet in 

 length, and appearing from nearly every node. A 

 structure in which 50 F. is maintained in winter will be 

 ample, and full exposure to sun should be permitted at 

 all times. This prevents immature growth, and flowers 

 are produced very freely. After flowering time, young 

 shoots appear, often from the old stems, and when a 

 few roots are formed and before they become too long 

 to go into a small pot without injury, remove them and 

 pot with care, place the young plants in a shady place 

 for a few weeks; in this way propagation is easily 

 accomplished. This section of epidendrums produce 

 seeds the largest known among orchids. They are 

 green in color, and under favorable conditions germi- 

 nate very readily. It is, in fact, much easier to get the 

 seeds to grow than to get the species to produce good 

 seeds, for when flowering plants are produced from seed, 

 there is an infinite variation that has not yet been 

 understood. 



Section V. PSILANTHEMUM contains but one species, 

 E. Stamfordianum, which requires the same general 

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