were well developed. The plants came from Mount Taygetas, and had 

 commenced to flower at Waltham Cross early in September. The form 

 differs from G. octobrensis in having a rather longer flower and commenc- 

 ing to flower at an earlier period. They are probably both forms of 

 G. nivalis. 



Vegetative growths on inflorescence. — Mr, Bowles also showed a well- 

 developed vegetative growth from an inflorescence of Kniphofia Northiae 

 seedling. There were three such growths upon the inflorescence, and 

 while all the rest of the inflorescence appeared dead, there was a green 

 strip of living tissue up the stem leading to the vegetative growths. 



Fasciation in Oxalis crenata. — From Messrs. Barr came a remarkable 

 example of fasciation in Oxalis crenata, the stem measuring over 4 inches 

 across. This is the first time a fasciated specimen of any species of 

 Oxalis has come before the Committee. 



Multigeneric hybrids. — Mr. Bowles gave notice that at the next 

 meeting the question of the nomenclature of multigeneric hybrids was to 

 be raised. 



Scientific Committee, October 13, 1908. 



Mr. E. A. Bowles, M.A., F.L.S., in the Chair, and fifteen members 



present. 



The late Mr. G. Nicholson. — A letter was read by the Chairman from 

 Lieut. Nicholson, thanking the Committee for the vote of condolence 

 passed at the last meeting. 



Snails and Water-Lilies. — Mr. Saunders, F.L.S., showed leaves of 

 Nymphasas eaten by water snails. Mr. Hudson, V.M.H., said that he 

 had found that an insecticide forced into the water so that it would rise 

 just underneath the leaves had proved an effective remedy against the 

 attacks of these pests, 



Galls. — Mr. Odell showed plants of the common Nettle galled by the 

 dipterous gall-fly, Cecidomyia urticae, from Stanmore Common, where 

 the galls had been abundant this season. From Mr. Arnold came 

 specimens of Beech leaves with the " nail galls " formed by the gall-fly 

 Hormomyia fagi. 



Curious growth of Potato. — Mr. Veitch, V.M.H., showed on behalf of 

 Mr. Rumsey, of Leyton, a curious Potato which had been growing in the 

 light but out of the soil for 18 months. It had, as usual under such 

 conditions, produced a number of short, thick, purplish shoots, reaching 

 in all to a length of about 2 inches to 2\ inches, and from these were 

 developed a large number of closely appressed greenish roots. 



Alien Weed. — Mr. Bowles showed specimens of Galinsoga parviflora, 

 a weed which has been known for some time in gardens in Surrey and 

 W. Middlesex, from a field near Enfield in Middlesex. 



Precocious flowering. — Mr. Bunyard, V.M.H., sent a specimen of 

 white Lilac just coming into flower, and Dr. Rendle mentioned that a 

 Horse Chestnut tree was now in flower on Putney Heath. 



Nomenclature of Orchid hybrids. — The following resolution was 

 received from the Orchid Committee : " That the Scientific Committee be
