BUDS AND STIPULES 



I have figured leaves of three members of this 

 family to illustrate this relation between leaf-sheath and 

 stipule. In the Parsley (fig. 314) the sheath is quite 

 entire; in Ostruthium (fig. 315) there is a distinct 

 shoulder on each side ; while in Fool's Parsley (JEthusa 

 Gynapmm) (fig. 316), a common British species, the 

 shoulder has grown out into a small but distinct stipule.

Speaking of Canarium, Bentham and Hooker say 

 (' Genera Plant.,' i. 324) : ' Folia exstipulata, vel pinnulis 

 inferioribus sessilibus stipulseformibus, imparipinnata,' 

 and again, c Foliola infima Canarii interdum stipulas 

 simulant' (p. 321).
