coloured E. X kewense. The latter re-crossed with the original purple 

 species gave purple hybrids with a yellow crest (not a purple crest as 

 in E. evectum), but re-crossed with the yellow species gave flowers of 

 a reddish-salmon colour, one, however, being more orange-coloured. 

 When E. X kewense was self-fertilized the offspring showed a gradation 

 between the deep yellow of E. xanthinum through various shades of 

 salmon to cerise and light rosy purple. The two extremes were 

 primrose yellow (much lighter than E. xanthinum) and clear purple 

 with a white crest touched with yellow in the centre. 



Wasps active in winter. — The Rev. Canon Fowler remarked that 

 near Reading a wasps' nest had been found on December 31, 1912, 

 in a quite active state. 



Scientific Committee, April 29, 1913. 



Mr. A. W. Hill, M.A., in the Chair, and five members present, with 

 Sir Arthur Hort, visitor. 



S cilia campanulata. — Mr. A. Worsley showed flowers of a Scilla 

 approaching S. campanulata in form, to draw attention to the colour 

 of seedlings of the pink form of that species which appeared in his 

 garden after the introduction of some white ones among the blue. 

 About one-third of the seedlings produced white flowers, rather less 

 than one-third pink or purplish-pink, and rather over one-third blue 

 flowers. It was not stated whether the flowers were self-pollinated 

 or whether promiscuous crossing had occurred. 



Effect of frost on Narcissus. — Mr. J. T. Bennett-Poe exhibited 

 a flower of Narcissus 1 Green-Eye,' to show the influence of frost, 

 which had caused the perianth pieces to remain undeveloped, and 

 to wither partially, while the corona remained unaffected. 



Narcissus : Variation in Wild Forms. — Sir Arthur Hort showed 

 a number of forms of Daffodils gathered in the Pyrenees, exhibiting 

 remarkable variation in colour and size. They mostly occurred in 

 rich pastures, and among them were bi-coloured and self-coloured 

 forms, as well as considerable variety in the breadth of the perianth 

 segments, and in the form and shape of the corona. 



Anthurium X conchifiorum. — A hybrid Anthurium, bearing the 

 name of A. x conchifiorum, was shown from the garden of Sir Trevor 

 Lawrence, Bart. It was raised by Mr. Bain by crossing A. Chamber - 

 lainianum with A. Scherzerianum. The leaves were long-stalked, 

 with blade (about 14 inches by 6 inches) cordate at the base and 

 acuminate ; the inflorescence differed markedly from that of A . 

 Scherzerianum in the breadth of the scarlet spat he, which in some 

 instances measured 4J inches in diameter by nearly the same in length, 

 and in the curious hooding at the somewhat cordate base of the 

 spathe. The spathe was glossy outside and dull within. 



Polyanthus and Daisy abnormal.— Mr. T. H. Dipnall sent an 

 inflorescence of a Polyanthus with a second umbel superposed upon 

 the first, and a Daisy without ray florets.
