This handsome species is characterized by its describer as being 
palmately 3- to 5-lobed, but it certainly significant that all of 
the forms from the Raritan formation are invariably 3-lobed and 
thatthe 5-lobed forms from the Dakota sandstone which Lesquereux 
referred to this species are indistinguishable from his species 
Aralia Saportana, which occurs at the same horizon and, in part 
at least, at the same locality. 
This is the most abundant form collected at Arthurs Bluff, 
there being fifteen specimens in the one small collection, several 
nearly complete leaves being present. These are all trilobate 
with toothed margins and agree exactly with the Raritan leaves 
of this species and with the trilobate leaves from the Dakota sand- 
stone like the one figured by Lesquereux on I. 21. fig. I. 
In the light of our present knowledge Aralia Wellingtoniana 
may be recharacterized in the following terms: 
Leaves variable in size, 10-20 cm. in length by 8 to 15 cm. in 
maximum width from tip to tip of the lateral lobes, average size 
about 15 cm. in length by 11 cm. in width; coriaceous, palmately 
deeply trilobate, with a rapidly narrowed and more or less extended 
decurrent base; lobes long, lanceolate, widest in the middle and 
natrowing below, somewhat abruptly acuminate, the median 
slightly the longest, diverging at an angle of about 30°, separated 
Y sinuses extending more than halfway to the base, narrowly 
Foun ed; margins entire below and for varying distances upward, 
passing gradually into dentate-serrate teeth, one to each secondary 
°F sometimes less in number, prominent in some specimens where 
they are more or less extended and directed upward, separated 
by wide Shallow sinuses. Primaries stout, suprabasilar, the 
median slightly larger than the laterals. Secondaries numerous, 
thin, regular, subparallel, ascending, since the angle of their 
aaa from the primaries averages about 33°, but slightly 
ai in their course, ultimately craspedodrome in distal parts 
‘tr where the margin is toothed, and. camptodrome in the 
ae half of the leaf, where the margin is entire. Areolation 
'stinct, reticulate, of quadragonal or polygonal meshes. The 
tenia — are relatively shorter and broader, with less ex- 
bes and more open and less deep sinuses. 
The present species may be distinguished from Aralia cotton-
