DESCRIPTION OF SPECIES. 135 



lobes entire, while in 1*1. xxxix, Fig. 1, the nerves are five and the lobes 

 narrower, the lateral trilobate along the base. This indicates a disposition 

 of the leaves to become casnally lobate. In Heer (loc. cit.), PI. xxxix, 

 V\g. 3 is referred to Platanus recurvatn Lesq. It is a trilobate leaf, five 

 nerved, with the lobes entire, which really ajjpears to lie referable to Aral ia 

 lli-wnhuidica. 



Fig. 3 has some real analogy with my hgnre of A. emnrginata of our 

 PI. XV, Fig. 4, which is referable as a variet}' perliaps of what I have form- 

 erh' considered as Liquidambar integrifolmm. It is, in fact, different, espe- 

 cially in the presence in this variety of two or even three pairs of liasilar 

 nerves jjarallel to each other. But there is, nevertheless, a distinct affinity 

 sluiwing it to be a continuation of the same type under a form somewhat 

 different. 



Habitat : Near Fort Harker, Kansas. Fig. 2, PI. LXVI, is No. 2741 of the 

 U. S. National Museum. 



Aralia berberidifolia, sp. nov. 

 PI. XVI, Fig. 11. 



A small coriaceous leaf or leaflet, ])almatelv five-lobed from the middle; 

 lobes oblong, rounded at apex to an abrupt sharply cuspidate point, sepa- 

 rated l)v obtuse sinuses; primarv nerves three, from above the base, lateral 

 forking. 



No traces of secondaries or areolation are observable upon the surface 

 of this small leaf, which is only 2.5""" long, 2*^™ broad between the apices of 

 the lateral lobes. The middle one is 15™"" long above the sinus, .5""" liroad, 

 the lateral graduallv smaller. 



I do not know of any fossil species to which this one can be compared. 

 Its five-palmate division refers it to the genus Aralia, however, of which 

 many species are described from the Dakota Group. By its hard, coriaceous 

 texture and the form of its sharply cuspidate lobes, it may be compared to 

 species of Berberis, such as B. trifoVtoJata of Texas, whose leaflets, though 

 generall}' trilobed, are sometimes five lobed and cnneate at the base. The 

 genus lierbei-is is represented in the Miocene flora of Europe by five species, 

 two of them of doubtfid affinitv, the others with linear leaflets \\ith()ut 

 relation to this fossil leaf from Kansas.
