Description. Leaves ovate in general outline with a rounded ultimately 

 cuneate base, constricted abruptly on each side the apical portion nar- 

 rowed and straight-sided with an emarginate apex. Length ranging 

 from 4 cm. to 9 cm. Maximum width, in the basal part, ranging from 

 2 cm. to 4 cm. Secondary and tertiary venation indistinguishable from 

 that of Liriodendropsis simplex or angustifolia of one or the other of 

 which it is probably a variant and not a distinct species. 



Forms answering to the foregoing diagnosis are recorded from Marthas 

 Vineyard, Massachusetts, and Glen Cove, Long Island, where they are 

 associated Avith large numbers of leaflets of Liriodendropsis simplex and 

 angustifolia. A single leaflet is likewise associated with these two species 

 in Alabama which fact lends emphasis to its doubtful specific rank. The 

 Maryland material is rare and not positively determined.

Description. Leaves small, ovate in general outline, inequilateral, with 

 rounded margins and apical auricles separated by a deep and rounded
