Art.19. MIOCENE PLANTS FROM SOUTHERN MEXICO—BERRY. 9 
substance thin, but firm and resistant. Petiole missing. Midrib 
mediumly stout and prominent, somewhat flexuous. Secondaries 
few in number, thin, four pairs diverge from the midrib at angles of 
about 45° and sweep upward in broadly ascending curves, sub- 
parallel with one another and with the lateral margins of the leaf, 
they are subacrodrome in appearance and are eventually lost in the 
gradually diminishing arches along the margins. Tertiaries thin, 
more or less percurrent. Aerolation fine, polygonal. Length about 
6 centimeters. Maximum width about 3 centimeters. 
This perfectly characteristic leaf has some features suggestive of 
the genera Bumelia or Bucida, but after much search amongrecent 
material, it appears to me to be most similar to the genus Moquillea. 
The latter comprises about a score of species of shrubs and trees of 
tropical South America, one of which extends northward an undeter- 
mined distance into Central America. The only other known fossil 
form is Moquillea stiibeli described by Engelhardt ® from the Miocene 
of Santa Ana in the Magdalena Valley, Colombia. The latter 
although similar to the Mexican species is more distinctly elliptical 
in form, but is undoubtedly closely related to it, thus emphasizing 
once more the South American facies of the Miocene Tehuantepec 
flora. 
Occurrence.—64 to 7 km. northwest of Palomares, State of Oaxaca 
Holotype.—Cat. No. 36817, U.S. N. M. 
Family CONNARACEAE. 
Genus CONNARUS Linnaeus. 
CONNARUS CARMENENSIS, new species. 
Plate 3, fig. 6. 
Leaves ovate in general outline, widest below the middle and more 
narrowed distad. Apex acute. Base broadly cuneate. Margins 
entire, full but somewhat irregularly rounded. Texture subcoriace- 
ous. Length about 10.5cm. Maximum width about 5cm. Petiole 
missing. Midrib stout and prominent, conspicuously thinning 
distad. Secondaries few and remote, mostly alternate, about four 
pairs diverging from the midrib at angles of about 45°, curving up- 
ward and ascending parallel with the lower lateral margins, sometime 
forking in the marginal region, and sometimes regularly campto- 
drome. Tertiaries mostly percurrent but often anastomosing 
midway between the secondaries. The fine areolation characteristic 
of the genus is not preserved. 
This obviously new species appears to be most closely related to 
the leaves of the modern species of Connarus, although it resembles
