xlv 



shown by Messrs. Barr, under the name of C. biflorus var. pnsillus, 

 which was very floriferous. 



Bifurcated Oak leaf. — He also showed a leaf of Oak with the lamina 

 bifurcated a quarter of the way above the petiole. 



Scientific Committee, March 30, 1915. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, with eleven 

 members present, and Mr. T. H. Chapman visitor. 



Galls of Chermes abietis. — Mr. W. C Worsdell showed an extra- 

 ordinarily large growth upon Abies Nordmanniana, due to the attack 

 of Chermes abietis. The growth on the twig shown was over inch 

 in diameter. 



Azaleas, Early -flowering. — Sir John Llewelyn showed fruits of 

 Azalea just ripe, and remarked on the fact that the fruit apparently 

 dehisces naturally in February. He had found titmice eating the 

 seeds in January before they were naturally shed. He is endeavouring 

 to get an early-flowering white Azalea somewhat like Azalea cccidentalis. 



Orange with longitudinal yellow Stripes. — Mr. E. M. Holmes ex- 

 hibited a fruit which he had purchased under the name of Madagascar 

 Bronze Orange, which was a deep bronzy-green except for a stripe 

 of ordinary orange colour about | inch in diameter in its widest part ; 

 one fruit had two such stripes. He had been told that the fruit came 

 from Spain, where the variety had been grafted upon the common 

 Orange, but could not vouch for the accuracy of the statement. 



Natural hybrid Orchids. — Mr. R. A. Rolfe, A.L.S., showed flowers 

 of two crosses he had made in order to satisfy himself of the alleged 

 parentage of two natural hybrid Orchids, viz., Odontoglossum gloriosum 

 X 0. Lindleyanum, which gave Odontoglossum X praevisum, the 

 natural hybrid ; and 0. Lindleyanum x 0. crispum (white), which 

 reproduced 0. x Coradenei. 



Hybrid Narcissus. — Mr. Chapman, Rye, showed Narcissus x cycla- 

 thinus, the result of a cross between C. cyclamineus $ and C. calathinus 

 ? . It is a flat-leaved form with flowers like those of C. cyclamineus 

 in shape and with reflexed segments, but with a pale colour, the corona 

 being lighter in tint than the perianth — an unusual character in 

 Narcissus. 



Bulbophyllum dichromum Rolfe. — Mr. J. O'Brien, V.M.H., exhibited 

 a spike of this uncommon Orchid sent him by Sir F. W. Moore, of the 

 Royal Botanic Gardens, Glasnevin. The flowers were, unfortunately, 

 very faded, as they had been cut a fortnight. The species was intro- 

 duced by Messrs. Sander & Sons, St. Albans, from Annam, through 

 their collector, Micholitz, and first flowered at Glasnevin in February 

 1907. It appears to be nearest to B. fuscopurpureum, native in the 

 Neilgherries, India (see Wight, Ic. PI. Ind. Or. v. p. 6, t. 165 1). It is 

 figured in the Botanical Magazine, t. 8160.
