It will be seen from this list that * hile bybridisers have been very 

 successful in some genera they have not obtained many results in several 

 otber, and in a few they have hitherto failed to secure any hybrids. 

 Thus of Aerides, Anoe^tochilus, Goodyera, Phalsenopsis, and Tnunia'one 

 hybrid each has been raised. Of Chyt-is two, and Phajus three, of Ma&de- 

 vallia and Zyg^petalutn three each, of Lrelia ^even, Dendrobium and 

 Calanthe nine each, Cattleya twenty-four, and Cypripedium fifty-thre^ 

 nparly half the total number having been ob'ained in the lasit-named 

 genus, In the case of the Cattleyas Mr. H. J. Veit<-h has observed that 

 the " members of the labia f a group and also the Brazilian species with 

 two-leaved stems, as C. intermedia, C. Acklandige, &c., cross freely with 

 each other and the Brazilian Laelias ; but neither the Cattleyas nor the 

 Brazilian Lselias will cr ss fre. ly with the Mexican Laelias, such as 

 albida, autumnalis, majali3, and acuminata, except L. anceps." From 

 the same authority we learn that the East Indian Cypripediums, though 

 crossing readily with each other, do not cross so freely with the South 

 American Selenipediums ; and though plants have been raised from 

 crosses between these two sections, they have not flowered yet. No one 

 appears to have succeeded in flowering an artificially raised hybrid 

 Odontoglossum up to the present time, although so many are regarded as 

 probable natural hybrids. Mr. Cookson obtained some seedling Odonto- 

 glossums from a cross between O. gloriosum or 0. Uro-Skinneri and 

 0. crispum, but they subsequently died. The late Mr. Spyer*, when 

 gardener to Sir Trevor Lawrence, obtained seed from crosses between 

 O. vexillarium and other species, but he informed me that he could 

 obtain no seed from crosses between 0. vexillarium and the Miltonias ;
