4. Juvenile Leaves. 



On Plates 266 and 267 are depicted leaves more juvenile than previously figured, 

 though in some cases it is probable, and indeed obvious, that leaves of an earlier stage 

 will be found. (See also Plate 268, 269, Part LVXI.) 



5. Mature Leaves. 



In the Plates depicting each species, a " mature " leaf has been shown wherever 

 possible. That is to say, a leaf as mature as was available at the time. But, as obser- 

 vations become extended, the tendency of leaves approaching maturity in this genus 

 is found to be in the direction of falcateness, and diminishing narrow-lanceolateness, 

 and the drawings now submitted show this. I believe that further observations will 

 additionally prove the truth of the position thus set up.
