flowers, both from Mr. Sherratt, gardener to J. Bateman, Esq. ; 

 to Struthiopteris orientalis, a fine Indian and Japanese species, 

 remarkable for its ovate sterile fronds and for the entire not mo- 

 niliform indusia of the fertile ones, from Messrs. Standish and Co. ; 

 to DieffenbacMa nebulosa, a pretty hybrid form of dwarf habit, 

 having the leaves clouded with yellow-green in the centre, darker 

 green at the edge, and marked with white spots, from the Society's 

 collection ; to Geonoma zamorensis, a fine pinnated Palm from 

 Mr. Bull ; to Azalea (indica) Madame Van der Cruyssen, a beauti- 

 ful bright rose-coloured sort, of good properties, from Mr. Turner ; 

 to Clematis Albert Victor and Clematis Miss Bateman, two varieties 

 bred from C. Standishii, the former a shaded lavender-purple, the 

 latter a pure white, both from Mr. Noble ; and to Pink alba mul- 

 tijlora, a remarkably pure white early forcing variety, from Mr. 

 Wadson, florist, Hammersmith. A Second-class Certificate was 

 given to Podocarpus Maki variegata, a shrubby Japanese plant 

 with linear white-margined leaves, from Mr. Bull. 



SCIENTIFIC COMMITTEE. 

 May 4, 1869. 

 T. Thomson, Esq., F.B.S., in the Chair. 



The Minutes of the last Meeting were read and approved. The 

 Secretary suggested that the plant known under the name of 

 Pinus Clanbrasiliana was probably raised from a cutting taken from 

 a Burr. The Douglas Pine forms similar Burrs. 



Mr. Berkeley reported on the diseased Sugar-canes from the 

 Malay archipelago sent to the last Meeting. He found the ducts 

 from the base upwards gorged with red matter, which was quite 

 sufficient to prevent healthy development. The heart of all the 

 young shoots w T as more or less decayed. The colour was so like 

 that of nitrogenous matter when tested with sugar and sulphuric 

 acid that he thought it might be worth enquiring whether an 

 unusual amount of sulphur existed in the soil. The upper leaves 

 were infested with a fungus ; but it is very doubtful whether this 

 has anything to do with the disease, though plants of Achillea 

 Ptarmica attacked by a very similar fungus produce a fresh crop 

 every year from the mycelium which seems to pervade every part 

 of the plant. 



Some Peach and Nectarine shoots were sent by Dr. Masters,
