SCIENTIFIC COMMITTEE. 



xliii 



Mr. Goodwin referred to the prevalence of the fungus Fmarium 

 biilbigemim this year, and thought the only effective method of dealing 

 with it was to lift all plants showing yellowing of foUage, and to 

 remove the remains of bulbs where blanks occurred. 



Zizania sp. — Sir John Llewelyn referred to the species of Zizania 

 cultivated in England, and said that Zizania aquatica always proved 

 an annual, but the plant grown under the name Z. latifolia was a 

 perennial. It did not flower, and there had therefore been no oppor- 

 tunity of verifying the name. A plant under that name was men- 

 tioned in Gray's " Flora of North America " and was thought to be 

 the same as Z. miliacea. 



Pelargonium Hybrids. — Mr. J. Fraser, F.L.S., continued his remarks 

 upon the scented Pelargoniums, deahng with the forms belonging to 

 Pelargonium capitatum and its hybrids. 



Intermittent Variegation. — Mr. W. Hales, A.L.S., referred to the 

 matter of intermittent variegation which had been brought to the 

 attention of the Committee some time ago, and said that a plant of 

 Seditm Telephium, after showing no signs of variegation for three 

 years, had this year become markedly variegated again. 



Small Narcissus Fly. — Mr. C. E. Shea showed numerous specimens 

 of the larvae of the small Narcissus fly Eumerus lunulattts {E. strigatus) . 

 He said they were proving particularly troublesome in his garden, 

 and that he was Hfting all bulbs which failed or showed signs of weak- 

 ness. A large number of the larvae was often found in one bulb, 

 up to eighty in one case, and thirty-two in another. Plants growing 

 in the sun appeared to be more liable to attack than those in shade, 

 as is usually the case with bulbs attacked by the large Narcissus fly. 

 He thought it probable that the larvae travelled from bulb to bulb 

 in the soil. 



" Reversion " in Odontioda. — Mr. R. A. Rolfe, A.L.S., showed a 

 flower of the cross Odontioda X Bradshawiae ' Cookson's var.' X 

 Odontoglossum spectabile, from the collection of Clive Cookson, Esq., 

 Wylam-on-Tyne. The flower closely resembled the Odontioda in 

 shape, but the scarlet colour was entirely suppressed. The flower 

 was white, with a few light-brown spots round the yellow crest of 

 the lip, and a little brown spotting at the base of the lateral sepals. 



Fasciation in Robinia Pseudacacia.—Mr. Bowles showed a branch of 

 Robinia from a garden at Enfield Lock exhibiting this phenomenon. 



Axile Proliferation in Quince. — Mr. J. Cheal sent a branch bearing 

 a fruit-like swelling from the apex of which a strong, woody shoot 

 had grown, bearing foliage and buds. The succulent flesh of the 

 fruit had shrunken to small proportions by this date, but in October 

 had been of the usual bright colour and consistence. 



Insects attacking Roots. — Mr. W. C. Worsdell, F.L.S., showed soil 

 from a garden in the North containing a great variety of small animals. 

 Among them were numbers of Collembola, which were probably the 

 most troublesome of those present.
