ANON ACE jE 105 



Anona, ? laurifolia, Dunal (fig. 139). 



Primary root very long, fleshy, thick, colourless, penetrating the 

 soil perpendicularly to a great depth, furnished with short stout 

 horizontal lateral rootlets at the base of the hypocotyl, and 

 immediately beneath the soil or at the depth the seed was buried 

 before germination. 



Hypocotyl long, stout, tapering upwards, glabrous, mottled and 

 streaked with red on a pale or colourless ground, giving the whole 

 a pale brown or brownish-red appearance, 8-9'5 cm. long, rising in 

 the form of a loop during germination. 



Cotyledons oblong, obtuse, petiolate, glabrous, very small in the 

 seed, but during germination increasing almost to the length and 

 breadth of the seed, and becoming much wrinkled and undulated to 

 conform to the inequalities of the much ruminated ends, finally 

 becoming separated from the axis when the hypocotyl has attained a 

 considerable size, and remaining embedded in the subterranean 

 seed between two equal halves of the endosperm, with a thin layer 

 of endosperm between them ; lamina T5 cm. long, 8 mm. broad ; 

 petiole 5-6 mm. long. 



Stem woody, erect, terete, hairy, with ascending adpressed hairs. 



Leaves simple, entire, cauline, alternate, distichous, exstipulate, 

 petiolate. 



Anona Cherimolia, Mill. 



Hypocotyl erect, terete, tapering upwards, stout, slightly gla- 

 brous, pale green, 5-5-7 cm. long. 



Cotyledons retained in the seed, which is subterranean, while the 

 hypocotyl straightens without them. 



Stem as in preceding species ; 1st internode 5-5 mm. long. 



Leaves simple, entire, cauline, alternate (first two sometimes 

 opposite), exstipulate, petiolate, alternately or almost oppositely 

 penninerved and reticulate, with the nerves incurved towards their 

 ends and uniting with those next above them, glabrous or nearly so 

 above, ciliate and more or less hairy beneath ; petioles semiterete, 

 channelled above, hairy, with adpressed hairs. 



Nos. 1 and 2. Alternate or subopposite, oblong-ovate, obtuse, 

 revolute at the margin, light green slightly glaucous above, glaucous 

 beneath. 



Anona palustris, L. 



Hypocotyl as in A. Cherimolia, but reddish-green ; 9 cm. long. 

 Cotyledons aerial, oval or oblong-elliptic, obtuse, entire, shortly
