The genus Crotonophyllum was proposed liy 

 Vclenovsky for leases from the Cenomanian 

 of Bohemia constituting the single species 

 Crotiinophyllnm critdcdim.- Recently I have 

 addi'd a second Upper Cretaceous species, 

 Cnitdnophi/lJuiii pdrul nr;rforwift from tlie Mid- 

 dendorf arkose memljcr of the Black Creek 

 formation of South Carolina.

Description. — Leaves medium sized or small, 

 oblong-ovate in general outline, consisting of 

 a somewhat inequilateral, oblong-elliptical basal 

 portion, and a small ovate-lanceolate terminal 

 portion separated from the basal portion by a 

 narrow sinus on each side which extends to the 

 nxidrib. Length of the lower segment about 

 41 centimeters. Maximum width, in the mid- 

 dle part, about 2 centimeters. Length of the 

 somewhat falcate upper segment about L5 

 centimeters. Maximum width about 4 milli- 

 meters. Margins entire, somewliat undulate. 

 Texture coriaceous. Petiole missing. Mich'ib 

 stout. Secondaries thin, subpanillel, more or 

 less immersed in tiu^ leaf substance, campto- 

 drome.

Plate I. VII, li-ruie 1. 



Description. — Leaves of small size, long- 

 petiolate, narrowly cuneatc in general outline, 

 tlie tip acimiinate and a shallow eniarginatiou 

 at the base. Length ranges from 2 to 3 centi- 

 meters. Maximum width, at or below the 

 middle, 1 ..'> to 2 centimeters. Margins entire, 

 regularly curvetl. Texture not coriaceous. 

 Petiole stout, slightly curved,, about 8 milli- 

 meters in length. Midrib stout. Secondaries 

 wt^U marked; four or five equally spaced sub- 

 opposite pairs diverge from the midrib at angles 

 ranging from 30° in the uppermost pair to 60° 

 in the lowest pair. Tertiaries thin but well 

 marked, closely spaced, and irregularly per- 

 current. Areolation o])solete. 



This rare smaU-leafed species is referred to 

 the form genus Euphorl)iophyllum since it 

 appears to belong to the Euphorbiaceae and is 

 not certainly referable to any one genus. It 

 greatly resembles the leaves of several Central 

 American species of Omalanthus, of" South 

 American species of Stillingia, and, except for 

 its somewhat smaller size, more narrowed apex, 

 and strictly entire margms, it might represent 

 a leaf of the monotypic genus. Hippomane

 knolls from the southern Florida Keys througli 

 the West Indies and the Antilles to the north- 

 ern coast of South America and both coasts of 

 Central America. Tlrough I have not ven- 

 tured to identify the fossil form as a species of 

 llil)|)omane, it may be exactly inatched by the 

 small, more acuminate terminal leaves of 

 nippomane mancinella Linne . E t tingshausen '
