which the species was establislicd. They are at least tweuty centimeters 

 long, eight centimeters broad at the middle, oblong-oval, and apparently 

 rounded to an acumen ; the point is broken. The essential character recog- 

 nized in the fragments found at the Raton Mountains and at Golden is the 

 direction of the secondary nerves, which, close, parallel, simple, pass straight 

 upward at an angle of divergence of 5U° to G0° from the midrib, and curve 

 near the borders, where they become effaced. This type of nervation is the 

 same in M. incequalis, Sap. (Sdz. FL, p. 107, pi. xi, figs. 4-7).

Leaf oblanceolate, gradually narrowed from the middle to the base ; lateral veins open, distant, 

 camptodrome. 



The relation of this leaf is not positively ascertained, for I have been 

 unable, as Weber also, to find any fragment of its top. The leaf is not coria- 

 ceous, but rigid, with borders very entire ; the preserved lower part is ten 

 centimeters long, its width where it is broken four and a half centimeters, 

 whence it is gradually narrowed downward to the petiole. The midrib is 

 not thick, but straight ; the secondary nerves, on an open angle of diverg- 

 ence of 50°, curving in passing toward the borders, arc distant, alternate, 

 mostly simple, but marked by the base of thick nervilles about in right angle, 

 and separated by a few short tertiary veins. In comparing this fragment 

 with Weber's description and figure (lor. ciL), I can see no difference, except 

 in the somewhat more open angle of divergence of the secondary nerves 

 in the European leaf

 Like the former genus, this one is in the present flora limited to the 

 North American continent, and represented by few species. One, A. triloba, 

 Dunal, the Papaw, is very common on the bottom-rands of the Middle and 

 Southern States as far south as Florida; three other species are limited in 

 Iheir range to the Southern States; a fifth inhabits Mexico.
