Endosperm rather copious, fleshy, white, brittle, embedding

Embryo straight, flat, nearly equal in length to the endosperm, 

 colourless ; cotyledons broadly oblong-oval, entire, and rounded at 

 both ends, closely applied face to face, embedded in the endosperm, 

 and a little narrower than it, about twice as long as the radicle ; 

 radicle oblong-elliptical, suddenly pointed, embedded in the endo- 

 sperm close to the micropyle. 



Seedling (fig. 377). 



Hypocotyl subwoody, erect, 

 terete, glabrous, pale green, l-l'o 

 cm. long, 1 mm. thick. 



Cotyledons petiolate, rotund- 

 oval, obtuse, trinerved, pale green, 

 glabrous ; lamina 9 mm. long, 6 

 mm. wide ; petiole channelled 

 above, 2- 5 mm. long. 



Stem soft and succulent at first, 

 erect, terete, glabrous or almost so, 

 pale green; first three internodes 

 each about 1 cm. long. 



Leaves simple, cauline, alternate, 

 stipulate, petiolate. 



No. 1. Oval, cuspidately acute, serrulate, with gland-tipped 

 serratures, obscurely penninerved ; petiole subterete, faintly chan- 

 nelled above, glabrous ; stipules free, subulate, acute, small. 



No. 2. Palmately tri-lobed and -nerved, finely serrulate at the 

 margin ; lateral lobes oblong, apiculate ; terminal lobe oblong-oval, 

 obtuse, apiculate. 



Nos. 3 and 4. With longer, more pointed and apiculate,

Primary root suddenly tapering to a fine point and furnished 

 with numerous strong lateral fibres. 



Hypocotyl erect, subflexuose, terete, suffrutescent, glabrous, pale 

 green suffused with red, 4'7 cm. long. 



Cotyledons foliaceous, petiolate, glabrous, entire ; lamina oval,
