Oc^onio^lossum iliustris^iinium. 



To overcome this difficulty, the International 

 Congress of Botany held at Brussels, 1 910, 

 formulated a rule that multigeneric hybrids 

 should receive a conventional generic name, 

 preferably that of a man connected with 

 Orchidology, to which is added the termina- 

 tion ara. This explains the origin of the 

 name Wilsonara insignis applied to the 

 trigeneric hybrid between Oncidioda Charles- 

 worthii and Odontoglossum illustrissimum 

 which has been raised by Messrs. Charles- 

 worth and Co., and exhibited by them at the 

 Royal Horticultural Society, June 6th, igi6, 

 when the plant obtained an Award of Merit 

 from the Orchid Committee and the raisers 

 were awarded a Certificate of Appreciation 

 by the Scientific Committee. The specific 

 name insignis signifies the noteworthy 

 character of this interesting hybrid. 



W. insignis resembles the Oncidioda parent, 

 although the flowers are much larger, being 

 2 J inches in width. The spike carried 10 

 pretty flowers with purplish-claret-red sepals 



Wilsonara insignis.— For kind permis- 

 sion to use the adjoining block of Wilsonara 

 insignis we are indebted to the Editors of the 

 Gardeners Chronicle.
