TIVBIUDISTNG ORCHIDS.

Passy (France), and Mr. Pilcher, gardener to S. Rucker, Esq., 

 of Wandsworth. Perhaps the most brilliant success has 

 attended the patience and perseverance of Mr. Dominy, of the 

 Royal Exotic Nursery, Chelsea, who has succeeded in crossing 

 several reputed genera, amongst which may be mentioned 

 Phajus with Calanthe, and Calanthe with Limatodes. 



I have here compiled a list of hybrid Orchids, with their 

 parents, where known. More might be added, but this is 



A. 



1. Column of an Orchid. A, anther; B, stigmatic cavity. 2. Pollinia of 

 Vandse (Burlingtonia) . 3 and 4. Pollinia of Epidendrese (Lselia and 

 Cattleya). 5. Pollinia of Malaxideae (Dendrobium) . 6. Pollinia of Ophrydese 

 (Disa). 7. Pollen grains separated by maceration, and seen under a 

 microscope. 



sufficient to show that much has already been done ; and we 

 may fairly ask, have these results done nothing for botanical 

 science ? By hybridisation and grafting we may prove the 

 natural affinity of plants far better than by poring over her- 

 barium specimens if not so quickly, with far greater cer- 

 tainty. Unfortunately for horticultural science, neither Mr. 

 Dominy nor Mr. Pilcher have as yet given us the details of 

 their successful experiments.
