The Garden and the Botanical Magazine, and were, further, easy to 
propagate, which some forms of this species are not. The whole 
of Mr. Chapman's stock had been derived from one bulb. 
Stipules of Hawthorn. — Mr. W. C. Worsdell, F.L.S., showed speci- 
mens of leaves from Crataegus sinaica, showing intermediate steps from 
leaf segments to so-called stipules and demonstrating that the latter 
belonged to the leaf-blade, not to the leaf-base, as true stipules do. 
Leaves of Hybrid Orchids. — Mr. J. Ramsbottom, M.A., exhibited 
a series of slides showing the characters of leaves of hybrid Orchids. 
The series included sections of the leaves of thirteen primary hybrids 
and their parents : —

They had been prepared by Mr. Charlesworth, who was studying 
the structure of hybrid Orchids, and it was found that where a structure 
existed in both parents, but developed to different degrees in them, 
the hybrid usually showed the same structure developed in an inter- 
mediate fashion ; when a structure was present in only one of the 
parents it might or might not be present in the hybrid, and if present 
was usually less well developed than in the parent possessing the 
character. 
A Large Rhododendron. — Sir Everard im Thurn exhibited photo- 
graphs of a tree of Rhododendron arboreum, growing in the rain 
forest of Ceylon, to call attention to the huge size of its trunks— of 
which there were several— each almost as large as a man's body, and 
showing great burrs and twists freely developed along them (fig. 34).
