UMBELLALES. 203 



decnrring- to the petiole; lobes long, oblong-lanceolate, abruptly 

 pointed, sharply equally dentate from above the base, the teeth 

 turned outside or slightly upward, separated by shallow sinuses ; 

 primary nerves broad and flat ; secondaries more or less oblique, 

 slightly curving or nearly straight in passing to the borders, 

 entering the teeth, craspedodrome, mostly simple; areolation 

 distinctly reticulate, in irregularly quadrate or polygonal meshes." 



"The leaves, which are 15 cm. to 16 cm. long, excluding the 

 petiole, vary, of course, in width according to the number of 

 lobes and their divergence from the median nerve, which, in 

 most of the specimens that I have seen averages thirty-five 

 degrees. The lobes are a little broader in the middle, slightly 

 narrowing to the sinusus, 7 cm. to 10 cm. long, and from 2 cm. 

 to 3 cm. broad at the middle. The separate lobe has the teeth 

 much larger, more turned upward, appearing also of a thicker 

 texture." 



"The species is so remarkably similar to A. Saportanca Lesq., 

 that at first sight it appears identical. It differs, however, by 

 the coriaceous texture of the leaves, the reticulate areolation, the 

 larger teeth, the more or less upwardly-turned secondaries, which 

 are not curved or camptodrome, but run straight to the teeth 

 and enter them; the base of the leaf is longer, decurrent, and 

 the lobes more abruptly or obtusely pointed." Lesquereux, 1892. 



This species is so well described by Prof. Lesquereux that his 

 description is introduced in to to above. It is an extremely hand- 

 some species and quite different from any other form in the 

 Raritan flora. The Raritan leaves are all trilobate, and it would 

 seem as if the 5-lohed form was only an occasional ^•ariant, 

 as the same species in its occurrence in the Tuscaloosa forma- 

 tion of Alabama is also trilobate. 



There is considerable resemblance to Aralia deciirrens, Vele- 

 novsky,^ of the Bohemian Cenomanian, in which, however, the 

 lobes are relatively narrower and longer, with coarser teeth and 

 deeper sinuses.
