CX1V PEOCEEDINGS OF THE EOYAL HOETICULTUEAL SOCIETY. 



Hybrid Orchids. — Mr. Kolfe, A.L.S., showed flowers of Epidendrum 

 evectum (purple) and E. xantliinum (yellow), and the hybrid raised by 

 crossing them ( = E. x hewense of a salmon colour). He also showed 

 flowers of E. x hewense crossed with E. evectum, producing a hybrid 

 having purple flowers (but not of the same shade as E. evectum), and of 

 E. x hewense crossed with E. xantliinum, this cross bearing flowers 

 resembling E. x hewense. When E. x hewense was self-pollinated it 

 reproduced flowers of three sorts bearing great resemblance in colour 

 to E. evectum, E. x hewense and E. xantliinum respectively. 



Various plants. — Mr. G. Paul, V.M.H., sent specimens of the two 

 shrubs Plagiospermum sinense, an interesting plant belonging to the 

 Bosaceae, with flowers nearly approaching the Gelastraceae in structure, 



Pig. 83.— Branched Tulips. (Gardeners' Chronicle.) (p. cxiii.) 



and bearing thorns a little distance above each of the leaf axils in addition 

 to the usual axillary bud, and Gleditschia Delavayi, a species from Yunan. 

 Both of these have proved hardy at Cheshunt, but Mr. Hales stated that 

 the latter had been killed by frost at Chiswick. 



Mr. Worsley showed an inflorescence of Oncidium varicosum var. 

 Bogcrsii to illustrate the great amount of variation in the lobing of the 

 labellum seen in this plant. 



Mr. Elwes, V.M.H., exhibited a number of fine flowers of the recently 

 introduced Regelio-Oncocyclus hybrid irises raised by Mr. van Tubergen. 

 He found that if kept dust dry for about five months they could be 

 successfully grown in this country, and did not die out as the Oncocyclus 

 irises usually do.
