Order RANALES. 
Family ANONACEAE. 
Genus ANONA Linnaeus. 
ANONA SARAVIANA, new species. 
Plate 3, fig. 2. 
Leaves of medium size, ovate in general outline, with a broadly 
ultimately decurrent base, and a conspicuously acuminate tip. The 
complete specimen figured is markedly inequilateral but whether or 
not this was a constant character is not determinable. Margins 
entire, somewhat irregularly flexuous. Length about 10 cm. Maxi- 
mum width, at or below the middle, about 4.8 em. Petiole missing. 
Midrib stout, prominent, and curved. Secondaries thin but promi- 
nent, about 10 regularly spaced subparallel pairs diverge from the 
midrib at angles of from 50° to 60° and are somewhat abruptly 
camptodrome, particularly toward the apex of the leaf, the lower ones 
arching more or less along and subparallel with the margins. Ter- 
tiaries thin but well marked, forming an open polygonal areolation. 
Nearly all of the three score or more existing species of Anona are 
American, ranging from southern peninsular Florida to Brazil, and 
especially common around the perimeters of the Caribbean. The 
genus was undoubtedly of American origin and of the score of more 
of known fossil forms, four well marked species occur in the lower 
Kocene of the Mississippi embayment region; there is an upper 
Kocene species in the coastal plain of Texas, and Miocene species are 
known from Costa Rica and Venezuela. There are also several 
Miocene and Pliocene species from Peru, Bolivia, and Chile. 
This new species is markedly distinct from any of the foregoing, and 
is rather smaller than most of them. Among recent forms it issur- 
prisingly close to Anona lutescens Safford of southern Mexico and 
Guatemala. 
Occurrence.—Isthmian railroad 3 km. north of Palomares on the 
Saravia estate State of Oaxaca. 
Holotype.—Cat. No. 36816, U.S. N. M.
