SAPOTACE^E 201 



Sideroxylon tomentosum, Eoxb. 



Hypocotyl 3-4 cm. long, 2-5-3'5 mm. thick, terete, woody, 

 glabrous, greyish-brown. 



Cotyledons nearly equal, shortly stalked, about 8 cm. long 

 and 2 cm. wide, ovate, rounded at the base, very obtuse at the 

 apex, entire, pinnatinerved, coriaceous, glabrous, dark dull green 

 above, light green beneath, very persistent, for when examined 

 eighteen months after germination they were still in perfect con- 

 dition. 



Stem like the hypocotyl, decreasing in thickness and increasing 

 in pubescence towards the top ; internodes 5-15 mm. long, flexuose. 



Leaves entire, alternate, subreticulate, coriaceous, tomentose 

 when young, glabrous when old ; petioles short, flattened above. 



Nos. 1-12. Elliptic or oblanceolate, acuminate, entire, pinnati- 

 nerved, coriaceous, pubescent when young, dark green ; lamina 

 4-6 cm. long, and T5-2 cm. wide ; petiole short, stout, pubescent, 

 often reddish, with a spine in its axil. 



Ultimate leaves lanceolate-elliptic, acute, glabrous and shining 

 on both surfaces, deep green above, lighter beneath, evergreen, 

 alternately penninerved with ascending nerves. Many of the 

 branches are reduced to spines one-half to three-quarters or one inch 

 long. 



Mimusops Balata, Gaertn. 



Hypocotyl well developed and woody at an early stage. 



Cotyledons very large, foliaceous, broadly oblong-ovate, obtuse, 

 sessile, obscurely penninerved with slender ascending nerves, coria- 

 ceous, dark green, glabrous, very persistent. 



Stem woody. 



Leaves simple, entire, alternate, exstipulate, shortly petiolate, 

 obscurely penninerved with slender nerves, coriaceous, persistent. 



Nos. 1-4. Inclusive, obovate-lanceolate, shortly petiolate, some- 

 what acuminate. 



Butyrospermum Parkii, Kotschy. 



Ovary of eight to ten carpels, eight- to ten-celled, each cell 

 one-ovuled ; ovules fixed by their ventral aspect to the axis, amphi- 

 tropous ; micropyle inferior. 



Fruit ellipsoid, baccate, one- or few-seeded by abortion ; pericarp 

 thin, fleshy. 



Seed ovoid or oblong-ovoid, or sometimes almost semigloboso 

 when it is flattened on the ventral aspect by pressure or con- 

 tact with other seeds or parts of the fruit ; testa brown, smooth,
