art.19. MIOCENE PLANTS FROM SOUTHERN MEXICO—BERRY. 21 
Order MYRTALES. 
Family MYRTACEAE. 
Genus MYRCIA DeCandolle. 
MYRCIA SARAVIANA, new species. 
Plate 5, fig. 1. 
Leaves small, ovate-lanceolate and falcate; widest below the 
middle and tapering upward to the acuminate tip, and downward 
to the acute base. Margins entire, slightly undulate. Texture 
subcoriaceous. Length about 3.5 cm. Maximum width about 1 
cm. Petiole missing. Midrib stout, curved. Secondaries numerous, 
approximately straight, subparallel; diverging from the midrib at 
wide angles, their tips connected by a slightly arched, acrodrome 
marginal vein. 
The present species may be readily matched by the leaves of several 
existing species of this genus. Among previously described fossil 
forms it appears to be most similar to Eugenia ovalifolia Engelhardt, 
described from the Tertiary basin of Loja in Ecuador. Afyrcia was 
present around the shores of the Gulf of Mexico and the Caribbean 
from the Upper Cretaceous to the present, and a considerable number 
of fossil forms have been described in recent years. The existing 
species number over 400 and are confined to the American tropics, 
being especially massed in northern South America. 
Occurrence.—Isthmian railroad } km. north of Palomares on the 
Saravia estate, State of Oaxaca. 
Holotype.—Cat. No. 36834, U. S. N. M. 
Family LECYTHIDACEAE. 
Genus LECYTHIDOPHYLLUM, new genus. 
LECYTHIDOPHYLLUM COURATARIOIDES, new species. 
Plate 6, figs. 3, 4. 
Leaves of large size, obovate and somewhat inequilateral in general 
outline, widest above the middle. Apex abruptly and bluntly 
angular. Base cuneate, markedly inequilateral. Margins entire, 
somewhat undulate. Texture subcoriaceous. Length about 17 cm. 
Maximum width about 7 cm. Petiole stout, its length unknown. 
Midrib stout and prominent. Secondaries stout, about nine sub- 
opposite pairs diverge from the midrib at angles of about 55°, curving 
regularly upward, subparallel and ascending, arching close to the 
margins until their identity is lost in the tertiary areolation. Ter- 
tiaries thin, very closely spaced, obliquely and irregularly percurrent,
