.SOME RESULTS OP THE HYBRIDISATION OF ORCHIDS. 147 



Very beautiful aud distinct hybrids were subsequently obtained in 

 PhalaBnopsis aud named respectively Rcthschildiana, Harriettce, F. L. 

 Ames, John Seden and Vesta ; and in other genera Ci/mhidium x 

 e'lurneo-Loivianum and Phaius x amab'hs. 



One of the most interesting and, in a horticultural sense, one of 

 the most useful of our latest acquisitions is Disa x Veitchii 

 raised from D. grandijiora fertilised with the pollen of D. racemosa. 

 In this hybrid we have the handsomest garden plant yet raised 

 artificially in the Tribe Ophryde^e which we have not brought within 

 the scope of this work. The genus Disa has been further enriched 

 by two hybrids which have been raised in the Hoyal Gardens at 

 Kew, one from D. tripetaloides ^ and D. grandifiora $ called D. x 

 keivensis ; the other from D. x Veitchii J and V. tripetahides $ 

 called D. x Premier. 



We will now proceed to enumerate the most noteworthy 

 results obtained by other operators, but our review of them 

 must necessarily be a restricted one, especially of those that 

 have flowered since the issue of the various parts of this work in 

 which a description of them would otherwise have been inserted. 

 Of a very large proportion of these we know nothing beyond the 

 notices of them that have appeared from time to time in the 

 periodical press, aud of such we can only mention those that have 

 been distinguished by some award or by a consensus of opinion 

 respecting their merit. Another large contingent consists of pro- 

 genies that have been derived from the same or reverse crosses as 

 others that preceded them, and they must therefore, in the case of 

 true hybrids, bear so near a resemblance to the older forms as to be 

 synonymous with, or simply varieties of them. All such are purposely 

 omitted where observed ; and also all secondary hybrids in which 

 the variability of the progenies is much greater. And lastly, there 

 is another category of hybrids and metis whose origin is unknown 

 or doubtful, and for which it is not easy to find a place in a 

 systematic treatise on orchids. 



Before Dominy had terminated his labours as an hybridist, and 

 even before the first efforts of Seden had borne fruit, two handsome 

 Cypripedes had been raised by Cross, Gardener to Lady Ashburton 

 at Melchet Court in Hampshire : Cypripediiim x Ashhurtoiiitt from 

 G. harhafum x C. insigne flowered in 1871 j G. x Crossii from G.
