LINNEAir SOCIETY OF LONDON. XXXIX 



June 18, 1874. 



Gr. J. xIllman, M.D., President, in the Chair. 



E. Birchall, Esq., James Leathern, M.D., and J. Harbord Lewis, 

 Esq., were elected Fellows. 



Mr. D. Hanbury, Treas. L.S., exhibited branches of Olivp 

 grown in the open air at Clapham, some bearing flowers, others 

 nearly ripe fruit ; also a specimen of Rlieum officinale, Baill., now 

 grown in this country for the first time, the source of the true 

 medicinal Turkey Eliubarb, aud pointed out the characters in which 

 it differs from other species of the genus. 



Dr. Hooker made a communication on the subject of some Indian 

 Garcinias to the effect : — (1) That the G. indica, Chois. {pur- 

 purea, Eoxb.), had been placed in a wrong section in Anderson's 

 review of the genus in the ' Flora of British India.' (2) That the 

 plant referred to under G. GrffitMi as the true Gamboge-plant 

 of Siam is identical with G. Morella, var. pedicellafa, of Han- 

 hvLTj (Linn. Trans, yol. xxiv. p. 489, t. 50), whicli Dr. Hooker 

 regards as a distinct species, and proposes that the name of G. 

 Hanburyi sliould be given to it. (3) That the G. hrevirostris of 

 Scheffer is identical with G. eugenicefolia of Wallich. (4) That the 

 name of G. ovalifoJia, Hook, f., must give place to the previously 

 published G. ovalifolia of Oliver's ' Flora of Tropical Africa ;' and 

 the Indian plant must take the name of spicata, it being a form 

 of XantJiocJiymus spicatus, W. & A. 



Professor Thiselton Dyer exhibited a young oak-plant with 

 three cotyledons, which had been sent to him by Mr. Cross, of 

 Chester ; also a pitcher-like development of a leaf of the common 

 cabbage, from Harting, Sussex, sent by Mr. H. C. AVatson to the 

 Kew Museum. 



IVIr. A.W. Bennett,F.L.S., exhibited drawings of the style, stigma, 

 and pollen-grain of Pringlea antiscorhutica. Hook, f., describing the 

 remarkable manner in which the poUen of Pringlea differs from 

 that of other nearly allied Crucifers, being much smaller and per- 

 fectly spherical, instead of elliptical with three furrows. This he 

 considered a striking confirmation of Dr. Hooker's suggestion
