Family MELIACEAE. 
Genus CEDRELA Linnaeus. 
CEDRELA MIOCENICA, new species. 
Plate 7, fig. 1. 
Leaflets sessile, lanceolate-falcate, widest at or below the middle, 
narrowing upward to the acute tip, and downward to the acuminate 
base. Margins entire. Texture coriaceous. Length about 8 cm. 
Maximum width about 1.7 cm. Midrib stout, prominent, curved. 
Secondaries thin, numerous, subparallel, camptodrome. ‘Tertiaries 
not visible in the collected material. 
This species, which is obviously new, represents a leaflet of a 
pinnate leaf, of a form rather commonly referred to the genus Sapin- 
dus by paleobotanists. It appears to me, however, to be more 
properly compared with Cedrela. The latter genus has about a 
dozen existing species, confined to the American tropics, and largely 
on the mainland of Central and South America. The only known 
American fossil species are those described by me from the Kocene 
of southeastern North America. 
Occurrence.—14 km. west of the telegraph station, San Jose del 
Carmen, State of Vera Cruz. 
Holotype.—Cat. No. 36827, U.S.N.M. 
Family SIMARUBACEAE. 
Genus SIMARUBA Aublet. 
SIMARUBA VERACRUZIANA, new species. 
Plate 7, fig. 6. 
Leaflets sessile (%), elliptical in general outline, with a rounded 
base and an abruptly acuminate tip. Margins entire, evenly rounded. 
Texture coriaceous. Length about 5em. Maximum width, midway 
between the apex and the base, about 2.6 cm., the one half of the 
lamina slightly wider than the other, and the tip markedly inequi- 
lateral. Midrib stout, curved, prominent on the under side of the 
leaflet. Secondaries thin, largely immersed, numerous, closely and 
fairly regularly spaced; they diverge from the midrib at wide angles 
of between 60° and 70°, pursue practically straight subparallel 
courses outward and have their tips connected by an arching 
marginal vein. Areolation not visible in the collected material. 
There is some doubt regarding the generic reference of this species 
because of the limited amount of material and the general similarity 
to the leaves of certain genera of tropical American Myrtaceae and 
Sapotaceae.
