A proposal of E>abeQliorst, also to include certain Cryptogams in 

 the observations, was considered premature, and therefore negatived. 



In the plants under examination the following phases should be ob- 

 served : 



1. The first appearance of the surface of the leaf. 



2. The first fully-expanded blossom, the pollen appearing prominent. 



3. The first ripe, normal fruit, without worm-hole, at the beginning 

 of the harvest of each sort of grain. 



4. General decoloration of the leaves. 



Eeraarlcs on the duration of vegetation with reference to the weather, 

 namely, the first and last frosts, and the duration of the snow-

Note on Dicuilanthe Zeylanica; by G. H. K. Thwaites, Esq. 



Owing to my overlooking a mistake made by the native draftsman, 

 this species is represented, in PL VIII. A. fi^, 1, of the present volume, 

 as being furnished with interpetiolarj' stipules ; such is not the case. 

 The description of the plant (at p. 270), explains the true structure.
