50 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
styles more pointed than Richard’s figures of the corresponding organs would 
indicate, while plate 27 shows that the flowers are not subterminal as originally 
described, but issue normally from the base of the branchlets, and that the 
mature petals are almost flat and rounded at the apex, instead of subtriquetrous 
and subacute. The indument of the peduncle and calyx is ferrugineous or deep 
cinnamon color, while that of the outer petals is composed of much finer hairs 
and is pale rufous or fulvous. 
Richard is quite right in recognizing the relation of this species to Annona 
cherimola, but, for the reasons assigned in describing the section Saxigena, it 
seems advisable to place this and A. crassivenia in a special section. 
This species, on account of the aromatic properties of the wood, is called 
“laurel.” The leaves are eaten by horses and cattle and the fruit by pigs. The 
latter is described as hard and sour and unfit for the table. The pubescence of 
its surface is fulvous rather than ferrugineous. Its seeds are remarkable for 
the bright golden, smooth, waxlike surface of their thin testa. They are in- 
closed when fresh by a thin membranous aril and are surrounded by scant pulp.

Section Saxigena. A small tree; branches slender, densely ferrugineous- 
tomentose when young, at length glabrate, grayish brown, longitudinally plicate- 
striate and bearing inconspicuous brownish lenticels; leaves 
orbicular or broadly ovate, rounded or retuse at the apex 
and rounded at the base, 5.5 to 7.8 em. long and 4.5 to 7 cm. 
broad, when young pubescent above and clothed beneath with 
thick ferrugineous tomentum, at length sparsely pubescent 
or glabrate above, the midrib and lateral nerves impressed 
and persistently ferrugineous-tomentose beneath, with re-

lets, 10 to 18 mm. long, persistently ferrugineous-tomentose 
and bearing a tomentose bracteole at the base; flowers resembling those of 
Annona cherimola, “dull greenish” when fresh; calyx small, about 4 mm. 
in diameter, gamosepalous, subtriangular, with the points obtusely acuminate 
or cuspidate; petals 6, the outer linear, tapering gradually toward the subacute 
apex, 24 mm. long and 4 mm. broad at the base, triquetrous or keeled within 
along the median line to the apex, hollowed at the base to receive the essential 
parts, clothed on the outside with a pale rufous or fulvous tomentum, lighter 
colored and finer than that of the calyx, grayish-tomentulose within; inner 
petals minute, not exceeding the stamens in length, rufous-tomentulose and 
keeled on the outside; torus convex; stamens numerous, about 1.38 mm. long; 
filaments brown, tapering to the base; pollen sacs 0.85 mm. long, contiguous, 
whitish, surmounted by the rounded apex of the connective, the latter not 
equal to the two pollen sacs in breadth; carpels numerous, closely crowded into 
a pyramidal gynecium, the ovaries about equal in length to the pollen sacs 
and densely clothed with long straight white ascending hairs; style ovoid or 
oblong, tapering to an obtuse stigmatic point with a median ventral suture;
