This species is frequently confused with Annona glabra L. and has been re- 
peatedly distributed as the latter species. It can readily be distinguished, how- 
ever, by its imbricate inner petals or by the small pits in the axils of the lateral 
nerves of its leaves above described. 
EXPLANATION OF PLatus 6, 7.—Pl. 6, unusually large flowers of Annona montana, the 
lower one with two outer petals and one inner petal removed to show the hemispherical 
andreecium, from the center of which issues the gynecium. From photograph of specimens 
in formalin from Mayagiiez, Porto Rico, received by the Bureau of Plant Industry, May 12, 
1910, made under the author’s direction by L, V. Hallock, of the U, 8. Department of 
Agriculture, Pl. 7, Annona montana Macfad., showing leaves with the minute pockets in 
the axils of the lateral nerves and immature fruit. From field photograph of fruit growing 
at Coamo Springs in files of the Bureau of Plant Industry, taken by Mr. Guy N. Collins, 
June 29, 1901 (no. 2878).
