SAFFORD—CLASSIFICATION OF ANNONA. 43 
insipid, adhering to the seeds, tallow-like with minute hard granules. (PLars 
23. Ficures 49, 50, 51, a, 52, a.) 
Type in the U. 8. National Herbarium, no. 850044, collected near Cahabon, 
Alta Verapaz, Guatemala, April 26, 1904, by O. F. Cook (no. 93). 
DISTRIBUTION: Northern Guatemala and southern Mexico. 
SPECIMENS EXAMINED: 
GUATEMALA: Type specimen as cited with field photograph (U. S. Dept. 
Agr. Bur. Plant Ind. no. 7247.) 
Mexico: Chiapa, State of Chiapas, Goldman 1007. 
LocaL NAME: Anona amarilla (Alta Verapaz, Guatemala). 
Annona lutescens is closely allied to A. reticulata L., from which it differs in 
its broader leaves (fig. 52) and its yellow fruit. Annona reticulata, commonly 
known as “bullock’s heart,” has long, 
narrow leaves (therefore figured by 
Plumier*? as “Annona foliis lanceo- 
latis’”) and its fruit turns red, at - ft 
} 
least on the sunny side, when mature. aN 
The present species, according to Mr. /\ Ip \ 
Cook, is recognized as distinct from > \V 
the common A. reticulata by the na- i\ (\ 
tives of Alta Verapaz, who call it A 
“anona amarilla.” In general appear- 
ance the fruit resembles very closely 
the common alligator apple of trop- 
ical mangrove swamps (A.glabra L.). \ 
but the latter may easily be distin- \ 
guished by its large flowers with 6 |/\ \ 
ovate valvate petals, its laurel-like 
leaves, its edible fruit, and its yellow RQ 
or tan-colored seeds. The difference 
in the stamens of the two species 
~ 
may be seen in figure 51, which also S

of the present species are very similar 
to those of A. reticulata L., yet this is also true of the flowers of A. squamosa L. 
The three form a subdivision of the section Atta and are very closely allied, but 
undoubtedly distinct, as in the case of the two chirimoyas, A. cherimola Mill. 
and A. longiflora S. Wats.
