Descnption. — Leaves elongate-1 anceolate, 

 somewhat inequilateral m outline, the apex 

 more or less extended and acunimate and the 

 base narrowly pomted. Length ranges from 

 10 to 16 centimeters. Maximum width, in the 

 middle part of the leaf, ranges from 1.7 to 3.2 

 centuneters. Margms entu-e, faintly undulate 

 and slightly rcvolute. Texture coriaceous. 

 Petiole very stout, at least 2 centuneters in 

 length. Midrib stout, promment on the lower 

 surface of the leaf, curved. Secondaries stout 

 and promment on the lower sm-face of the leaf; 

 10 to 16 irregularly spaced pans, opposite to 

 altenuxte, diverge from the midrib at wide 

 angles, somewhat irregular hi their courses, 

 curve upward, and arch m the margmal region, 

 the distal pans, jiarticularly when the apex is 

 prolonged as an acumen, divergmg at angles 

 approaching 90°, nearly straight in their 

 coiu'sos, their tips joined by flat arches sub- 

 Ijarallel with the margins. Tertiaries distinct, 

 forming rather large quadrangular or polygo- 

 nal meshes. 



These leaves have a characteristic appear- 

 ance, well shown in the accompanying figures, 

 whicli are chosen to represent the extremes of 

 observetl variation — the one relatively shorter 

 and wider, with an obtusely pomted tip, the 

 other similar but witli a produced aciuninate 

 tip. Li sp(H;imens preserved in clay ironstone, 

 like those from Louisiana, Hurleys, and Wolf 

 River, tlie venation as a rule is entirely obsolete. 



This species, thougli it suggests certain pre- 

 viously described Tertiary species of other 

 areas, is clearly distmct from any of them. It 

 is somewhat similar to Oreodaphne mississip- 



piensin Berry, a Wilcox fornr common at several 

 localities, but the specifics difl'enMices ai"e obvi- 

 ous and need not be enumerated. Among 

 recent Lauracere it appears to \w, most like the 

 Brazilian tropical species Mespilodaphne sassa- 

 fras Meissuer.

 the geology of Louisiana, p. 287, pi. 45, fig. 1, 1899. 



Description. — Leaves medium sized, elliptical 

 m general outlme, the apex narrowed and 

 bluntly pomted, and the base equally nar- 

 rowed, but finally much decurrent. Length 

 about 8.5 centimeters. Maximum width, niid- 

 way between the apex and the base, about 

 3.5 centimeters. Margins entire, slightly 

 irregiilarly rounded. Texture subcoriaceous. 

 Petiole long and stout, about 2.5 centimeters 

 in length. Midrib stout, more or less curved. 

 Secondaries rather stout, mostly subopposite; 

 about eight unequally spaced pairs diverge 

 from the midrib at wide angl(^s, especially in 

 the basal jiart of the leaf, where they are also 

 more closely spaced; they curve gently and 

 regularly upward and are sul)parall(d and 

 camptodrome dose to the margins, witli which 

 they eventually become subparaU(>l. Tertiari(>s 

 at right angles to secondaries, tliin, percurrent 

 or forkmg to form large pentagonal meshes.
