Hypocotyl erect, terete, glabrous, slender, purplish, 1-2-2'! cm. 

 long. 



Cotyledons oblong-oval, obtuse, 

 entire or obsoletely emarginate, alter- 

 nately nerved with one or two of the 

 lower pairs stronger than the rest, if 

 one pair they become incurved and 

 unite with the midrib near the apex, 

 while if two pairs are strongly de- 

 veloped they unite about the middle 

 of the cotyledon and then proceed to 

 the apex, shortly petiolate, glabrous, 

 subglaucous-green, often stained be- 

 neath with purple ; lamina 6-8 mm. 

 long, 4-5 mm. wide ; petiole chan- 

 nelled above, convex on the back, con- 

 nate at the base around the plumule, 

 purplish, 1-1-25 mm. long, ciliate at 

 the margin. 



Stem erect, terete, thinly hairy or 

 pubescent, green or purplish, ulti- 

 mately shrubby ; 1st internode T25- 

 2 mm. long ; 2nd 1-75-6 mm. ; 3rd 

 6-10 mm. 



Leaves simple, entire, cauline, op- 

 posite, exstipulate, petiolate, young 

 ones densely ciliate. and hairy on both 

 surfaces, with the hairs curved or 

 bent towards the apex, alternately and 

 incurvedly penninerved, the nerves 

 uniting and forming a series of large 

 reticulations towards the margin, 

 glaucous-green at least in the young 

 state ; petioles short, grooved above, 

 subcarinate or merely convex be- 

 neath, slightly connate at the base, 

 more or less hairy. 



First and second pairs small, oval, 

 obtuse, suddenly tapering to the base. 



Third and forth pairs oval, obtuse, 

 often cuspidate, suddenly tapering to 

 the base, somewhat larger than those
