SCIENTIFIC COMMITTEE, MAY 1.

quite green, with the object of ascertaining whether anyone had discovered 

 the significance of this variation. 



Fruit of Lilium candidum. — Dr. Masters showed a ripe capsule of 

 Lilium candidum containing a few apparently well-formed seeds among 

 a large number of imperfectly formed ones. Rev. W. Wilks said that 

 numbers of capsules were produced at Wisley on this lily, but he did not 

 know whether they contained any perfect seed. Mr. Elwes, V.M.H., said 

 that plants had been raised from seed produced after artificial fertilisation. 



Pinus syhestris destroyed by Beetles. — Mr. Saunders took some speci- 

 mens sent from Suffolk, and will report upon them later. See p. Ixxii. 



Convolvulus azureus Leaves inj2ired. — LieaYes of a plant of Convolv^ilus 

 azureus which had been inadvertently left in a cucumber-house were sent 

 by Mr. A. C. Barlett, of Pencarrow Gardens, Cornwall. Many spots were 

 present on the leaves, and from the centre of each a rather large black 

 projection arose. These spots are caused by a checking of transpiration, 

 and the production of warts, or " intumescences," as a consequence, and 

 are quite similar to those shown recently on Pelargonium, Hydrangea, 

 and Fuchsia. A proper balance between heat, moisture, and light must 

 be maintained if such unhealthy growth is to be avoided. 



Vines dying hack. — Some vine shoots, the leaves of w^hich became 

 brown first at the edges, then farther back, were received. Mr. Massee 

 took these for further examination. See p. Ixxii. 



Richardia Elliottiana malformed. — Mr. E. H. Jenkins, F.R.H.S., of 

 Hampton Hill, sent a curious malformation of Bichardia Elliottiana. 

 En the place of leaves were long narrow structures resembling petioles, 

 and in one case a much attenuated growth with wavy margins ; and while 

 the spadix appeared to be properly developed, the spathe was reduced to 

 a thread-like outgrowth about 3| inches in length. The corm and roots 

 were normal. 



Plants dc. exhibited. — Cypella Herberti. Mr. Worsley showed an 

 inflorescence of this curious and beautiful South American irid, 

 Tropceohcm Lobbianum x T. canariense. He also showed flowers of 

 this cross, and remarked that while in summer the flowers produced were 

 of a bright red, in winter the petals were usually margined with yellow. 

 He found that the flowers borne by plants raised from cuttings of this 

 plant varied considerably, and passed specimens round in illustration of 

 his remarks. He also showed a flower of a Trojpcsolum having two 

 spurs. The stem bearing it appeared to be fasciated, and the plant from 

 which it came was raised from a cutting taken from a fasciated stem, 

 Deutzia scahra. Dr. Masters drew attention to the true D. scabra 

 shown by Messrs. Paul & Son, Cheshunt, and pointed out that the plant 

 usually grown under that name was really D. crenata, a species with 

 which it has long been confounded. 



Ceanothus Feyidleri. — He also commented upon this plant, which, 

 unlike other members of the genus, has a grey bark, is spiny, and bears 

 white flowers. It is a mountain plant, and comes from the South-Western 

 States of North America. 



Fritillarias. — Mr. Elwes, V.M.H., showed several " species " of 

 Fritillaria, and said that he thought that in all probability many wwe 

 geographical forms of one species. He thought this to be the case in
