ON SEEDLINGS 



Embryo curved or rounded on itself, filling the whole interior of 

 the seed, yellowish- white. 



Cotyledons oval or nearly round, fleshy, sessile with their edges 

 to the hilum ; radicle accumbent on the edges of the cotyledons, 

 angled, obtuse, rather longer than the cotyledons. Owing to the 

 thickening of the testa near the basal notch there is probably a 

 slight oblique emargination in the cotyledons.
