APOCYNACE^E 221 



Wrightia tinctoria, B. Br. 



Hypocotyl erect, terete, glabrous, woody, 3-5-4 cm. long, 

 brownish. 



Cotyledons unequal, membranous, oblong, obtuse, entire, petio- 

 late, glabrous, green, distinctly pinnatinerved like the leaves. 



Stem erect, terete, herbaceous, ultimately woody ; 1st internode 

 3'5 cm. long ; 2nd about 3 cm. ; 3rd rather shorter. 



First leaves simple, entire, cauline, opposite, decussate, oblong- 

 lanceolate, obtuse, petiolate, exstipulate, glabrous, green with a sub- 

 glaucous hue above, pinnatinerved; petioles short, flat, slightly 

 furrowed above. 



Parameria glandulifera, Benth. 



Hypocotyl woody, terete, pubescent, 1'7 cm. long, 2 mm. thick, 

 pale ashy grey. 



Cotyledons shortly petiolate, ovate, obtuse, entire, coriaceous, 

 pale green, 1-6-2-2 cm. long. 



Stem erect, terete, thickened at the nodes, 2 mm. thick, and 

 gradually tapering upwards, shortly, finely and densely pubescent ; 

 1st internode 4-8 mm. long ; 2nd 1-5 cm. ; 3rd 1-8 cm. In different 

 specimens these lengths are variable. 



Leaves simple, entire, cauline, opposite, decussate, shortly petio- 

 late, subacuminate, obtuse, coriaceous, penninerved, pale green, 

 shining, finely pubescent on the midrib beneath ; petiole 3 mm. long, 

 flattened above and convex beneath, finely and densely pubescent, 

 apparently connate at the base and surrounding the stem, forming 

 a transverse scar with small black, stipuliform teeth on its upper 

 edge. 



First pair falling early, even before the cotyledons. 



Second to fourth pairs lanceolate-elliptic, acuminate, obtuse, 

 finely penninerved. 



Echites umbellata, Jacq. (fig. 515). 



Hypocotyl erect, terete, slender, finely and minutely pubescent, 

 about 8-10 mm. above the soil. 



Cotyledons oblong, obtuse, entire, shortly petiolate, glabrous, 

 coriaceous, alternately and ascendingly penninerved, with the nerves 

 incurved and uniting at the tip, appearing somewhat reticulate, deep 

 green above, with generally pinkish veins, paler beneath and often 

 reddish, horizontal from ascending or suberect petioles ; lamina 

 9-5-10-5 mm. long, 5-5'5 mm. wide ; petiole semiterete, channelled 

 above, slightly connate at the base, finely and minutely pubescent 

 like the stem, dull purplish, about 1 mm. long.
