190 TRANSACTIONS AND PROCEEDINGS OF THE [Sess. lv. 



L. niticla, Cav.,* is found along with L. mineifolia. It 

 is distinguished from all the others in having leaves with 

 5 to 7 pinnae. Hairs are numerous along the margins of the 

 pinna3, and few on the two surfaces. Almost all the 

 epidermal cells, including those encircling the stomata, have 

 brown contents. The stipules bear a considerable number 

 of hairs on the outer surface, and stomata, probably soon 

 functionless, are present, mostly near the apex. 



Volkens t studied this species under cultivation. He lays 

 great stress on the excretory power of the stipules, and 

 questions whether . the leaves excrete at all. It is evident, 

 however, from the specimens examined for this communica- 

 tion that the leaves themselves, especially in the young 

 state, take an active part in covering their surfaces with the 

 excretion found on them. 



In transverse section the inner (upper) epidermis was 

 seen to have deeper cells than the outer surface, but the 

 difference in depth is by no means so great as in the other 

 three species. 



Volkens ;j; has found a distinct cuticle on the outer surface, 

 and none on the inner, a condition asfreeine; with that seen 

 in all the stipules of the other species.
