LEGTJMlNOSyE 441 



When the stem has attained some length the leaves on the upper 

 part are developed into tendrils (fig. 285, B) as described above, and 

 enable the plant to climb. 



TRIBE PHASEOLE.E. 



Clitoria Ternatea, L. 



Fruit a legume, linear, compressed, more or less thickened at 

 the sutures, dehiscing longitudinally by two valves, many-seeded. 



Seed transversely oblong, rounded at either end, much compressed 

 laterally, thicker along the ventral aspect, smooth, black, somewhat 

 shining, minutely reticulate ; hilum a little below the middle of the 

 seed on the ventral aspect, forming a depression and partly overlying 

 a thickened part of the testa corresponding to the chalaza ; micropyle 

 contiguous to the hilum on the ventral aspect, inconspicuous ; raphe 

 none. 



Seed 7'25 mm. long, 4'75 mm. wide. 



Endosperm absent. 



Embryo curved, large, and occupying the whole interior of the 

 seed to which it conforms, brownish-yellow ; cotyledons accumbent 

 with their edges to the placenta, oblong, obtuse, entire, minutely 

 and rather unequally auricled at the base, rather unequal-sided owing 

 to the radicle and the thickening of the chalaza on the ventral aspect, 

 closely applied face to face, thicker along the ventral than the dorsal 

 aspect, equal in length to the interior of the seed ; radicle cylindrical, 

 obtuse, curved round the ends and along the ventral aspect, partly 

 beneath the edges of the cotyledons and having its tip slightly em- 

 bedded in the micropyle. 



In specimens examined the bases of the cotyledons were obliquely 

 cut away owing to the curvature of the seed on the opposite side to 

 that followed by the radicle, so that the auricles on that side were 

 smaller than the others. 



Seedling (fig. 286). 



Hypocotyl 3 or 4 cm. long, T5-2 mm. thick, terete, slightly 

 pubescent, greyish-green, herbaceous. 



Cotyledons nearly equal, shortly petioled, about 2 cm. long, T25 

 -1-5 cm. broad, 1 mm. thick, oblong, oblique at both ends, entire 

 (one half of blade forming a sector or semicircle with the midrib as 

 base, the other a very long, obtuse rectangle), obscurely penninerved, 

 glabrous, fleshy, yellowish-green on the upper, whitish on the lower 

 surface. 



Stem herbaceous, nearly terete, pubescent, light green ; inter- 

 nodes 1 or 2 cm. long, 1-1'5 mm. thick. 



Leaves. Nos. 1 and 2. Opposite, 1-5 cm. above the cotyledons
