ONAGKARIELE 577 



axis, covered especially in the young state with pale-coloured or 

 white papillae. 



Seed obovoid, slightly compressed, flattened on one side and 

 produced into a wing at each edge, and a broader wing or crest 

 round the apical end, with the lateral wings ultimately incurved, 

 producing a deep groove or concavity, and the crest crenate or 

 toothed at the margin ; testa subcrustaceous, deep brown, tubercu- 

 lated ; hilum and micropyle basal, inferior, contiguous ; chalaza 

 apical; crest and wings readily separable from the rest of the 

 seed. 



Endosperm forming a thin white film lining the interior of the 

 seed. 



Embryo comparatively large, straight, colourless, filling the 

 entire cavity of the seed to which it conforms in general outline; 

 cotyledons oblong, slightly emarginate from a thickening of the 

 chalaza, auricled at the base, plano-convex, occupying the greater 

 part of the length of the seed, and lying in its broader plane with 

 their backs to the placenta ; radicle turbinate, obtuse, several times 

 shorter than the cotyledons, but protruded a little way beyond the 

 auricles, and filling up the basal and narrow end of the seed. 



Eucharidium concinnum, Fiscli. et Meyer. 

 Seeds 1-5-2-25 mm. long, '75-1 mm. wide. 



DEVELOPMENT OF COTYLEDONS. 



Cotyledons immediately after germination shortly and broadly 

 oblong, obtuse, emarginate, with a small purple tooth in the notch, 

 shallowly auricled at the base, sessile, minutely dotted all over the 

 upper surface with glands. Hypocotyl minutely glandular. Pri- 

 mary root simple, furnished with root-hairs. 



Seven days after germination they are oblong-obovate, emargi- 

 nate, constricted below the middle, with the upper part or true 

 cotyledon transversely oblong, and the lower similar, but smaller and 

 shortly ciliate at the margin, very shortly petiolate. 



Sixteen days after germination they have become broadly ovate, 

 blunt, emarginate with the apical tooth very small and incon- 

 spicuous, shortly petiolate ; upper part or true cotyledon transversely 

 oblong, much shorter and narrower than the lower or foliaceous part, 

 minutely and inconspicuously pubescent ; lower part with three to 

 four crenatures on each side and more conspicuously pubescent all 

 over the upper surface than the upper part. Midrib distinct to 

 the apex. 



Twenty-five days after germination the upper part or true
