Ordinary Meeting, December i6th, 1901. 



Charles Bailey, F.L.S., President of the Section, in the Chair. 



Mr. H. Hyde exhibited specimens of Salvinia na/ans and 

 Azollafiliaila, growing, the former showing fructification. 



The President noted the discovery at Hatchmere, Delamere 

 Forest, of the rare sedge Cladium Jamaicense, Crantz, perhaps 

 better known as C. Mariscus, R. Br. 



Mr. J. C. Melvill, M.A., read a paper on the genus 

 Chrysanthemum, L., with special reference to the origins of the 

 cultivated species C. indicum, L., and C. sinense, Sabine, wild 

 examples of which, from his herbarium, were exhibited. These 

 were collected mostly by Mr. Hastings C. Dent, F.L.S., in 1886, 

 from the vicinity of the Ming Tombs, Pekin, China, the ray 

 florets being pink, with yellow disk. The C. indiciim, not found 

 wild anywhere in India, is native in China and Japan, and is 

 the origin of the short-petalled varieties and pom-poms.
