52 COOL OECHJD GROWING. 



Seedling Deiidrobes and Cypripediums have been raised at 

 the Fairfield Nurseries — 'the latter from imported seed ; and 

 Mr. Mitchell, gardener to Dr. Ainsworth, Lower Broughton, 

 near Manchester, has also some very promising seedling Den- 

 drobes. Our sketch shows seedling plants about three years 

 old, the result of fertilising D. heterocarpum with the pollen 

 of D. nobile. 



Several hybrid Cattleyas, Lselias, and Cypripediums have 

 been raised by Mr. Dominy, whom we have also to thank for 

 Cypripedium Harrisianum and C. vexillarium. Calanthes 

 are very easy to propagate, for if an old bulb has its top broken 

 off it will often produce two or three young plants round the 

 fracture. The delicate little Pleione humilis propagates itself 

 very freely, producing numerous little bulbils on the apex of 

 of its old decaying pseudo bulbs. These fall off and root 

 freely into the living sphagnum on the pot-tops. The pre- 

 ceding methods are those generally adopted in the nursery 

 trade, and are equally applicable to private establishments. 



Our illustration of Phajus grandifolius shows a young plant 

 produced adventitiously on the flower-stem, and also young 

 plants on the flower-stem of Consul Schiller's Phalae- 

 nopsis. This also illustrates a semi-circular raft on which 

 Phalseuopsids, Saccolabiums, &c., are successfully grown by 

 Mr. Turner, Leicester. Grown in this way, with the roots 

 exposed, is far more rational than to bury the aerial roots in 

 a mass of cold, wet, and often rotten sphagnum, as is generally 

 done when these plants are grown in pots.
