SCIENTIFIC COMMITTEE, FEBRUARY 9.

Scilla, dc. — Mr. Woraley showed an inflorescence of Scilla haemor- 

 rhoidalis, a plant with rather inconspicuous flowers followed by larger, 

 fleshy fruits. He also remarked upon the inconstancy of the arrangement 

 of the spines in certain "of the Cacti in various stages and at different ages, 

 and stated that, in his opinion, the arrangement of the spines constituted 

 an insecure basis for the classification of this family. 



Fasciation. — From Sir Trevor Lawrence, Bart., came a fasciated 

 specimen of Anthurium bearing two spathes and spadices. Mr. E. H. 

 Jenkins sent a fasciated specimen of Daphne japonica. 



Cattleya Trianaei malformed. — A flower of Cattleya Trianaei having 

 three stamens and a much reduced perianth was received from Mr. Gurney 

 ^Yi]son, and referred to Mr. Saunders for further examination. 



Varieties of foliage of Cyclamen. — Mr. Bowles showed a large number 

 of leaves of Cyclamen hederaefolium from his garden, exhibiting great and 

 wide variation in the arrangement of the markings upon the foliage, 

 especially in the extent of the whitish margin and median blotch which 

 is usually present. He found the variations to be characteristic of, and 

 retained by, the individual plants. 



Scientific Committee, February, 9, 1909. 



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

 present, and Mr. Gurney "Wilson visitor. 



Malformed Orchids. — Mr. Saunders, F.L.S., reported that the flower 

 of Cattleya Trianaei referred to him from the last meeting showed three 

 perfect stamens surrounding the pistil, three very short and regular petals, 

 and three sepals shorter still. Mr. Saunders showed drawings illustrating 

 these points. 



Albinism in Orchids. — Mr. Gurney Wilson exhibited specimens in 

 illustration of the inheritance of albinism in Dendrobiums. He found 

 that Dendrobium Murliinianum crossed with D. Ballianum, the former 

 not a pure albino, though pale, the latter nearly white, gave seedlings 

 almost exactly like typical D. nobile. D. nob He album (virginals) which, 

 when selfed, gives quite white seedlings, when crossed with D. Findlay- 

 anum gives D. " Cybele," all the seedlings being alike, and no light forms 

 among them. Similarly, Dendrobium Wardianum album crossed with 

 D. nobile album gives all coloured flowers. These " reversions" to 

 coloured forms confirm the results that have been obtained in crossing 

 Sweet Peas and Stocks. 



Floral proliferation in Cyclamen. — Mr. L. Lawrence (gr. to E. 

 Gregory, Esq., of Shoreham) exhibited a plant of Cyclamen showing floral 

 proliferation. The seed was from Lowe's Cyclamen " Salmon Queen," 

 and this was the only plant which had produced such flowers. All the 

 flowers on the plant were alike, and every one had five perfect flowers 

 arising from within the calyx, probably axillary to the sepals, though 

 apparently alternating with them, and surrounding the central corolla, &c. 



Hippeastrum pardinum. — Mr. Worsley exhibited flowers of a form 

 which he regarded as belonging to this species. He considered the species
