ON SEEDLINGS 



Hypocotyl erect, terete, glandular-pubescent, almost colourless, 

 1-1-3 cm. long. 



Cotyledons subreniform, deeply and 

 broadly emarginate with a mucro in the 

 sinus, two alternate incurved nerves on each 

 side, thinly glandular-hairy on both surfaces 

 and glandular-ciliate ; lamina 4-5 mm. 

 long, 6-7'5 mm. wide ; petiole semiterete, 

 decurrent on the hypocotyl or subconnate, 

 glandular-pubescent, channelled above, 

 3-4-5 mm. long. 



Stem herbaceous, slender, erect, ulti- 

 mately climbing ; 1st internode -5-1 mm. 

 long. 



Leaves simple, cauline, opposite, ex- 

 stipulate, petiolate, alternately penninerved, 

 glandular-hairy on both surfaces, bright 

 green ; petioles semiterete, channelled 

 above, somewhat dilated at the base, 

 glandular-hairy. 



First pair rotund, obtuse, five- to 

 seven-angled or -toothed, with a strong 

 nerve entering each tooth, which is tipped 

 with a mucro. 



Ultimate leaves bipinnatisect and terminating in a simple or

Crescentia Cujete, L. (fig. 575). 



Hypocotyl erect, terete, minutely and finely pubescent, pale green, 

 1'5-1'8 cm. above the soil. 



Cotyledons broadly ovate-oblong, very obtuse, rather deeply and 

 narrowly emarginate, appearing subcordate from a sudden curvature 

 at the base of the lamina, petiolate, trinerved with a few short alter- 

 nate nerves directed upwards, light green above, paler beneath, 

 glabrous ; lamina l'2-l - 35 cm. long, 1*15 cm. wide ; petiole with 

 a shallow furrow on each side of a median ridge, minutely pubescent, 

 pale green, connate at the base, ascending and bearing the lamina 

 horizontally, 4 mm. long. 



Stem erect, subterete in a very early stage with a shallow furrow 

 on two sides, very shortly pubescent, pale green, ultimately woody, 

 with a pale-coloured, rough and knotty bark ; 1st internode 8- 

 10 mm. long. 



Leaves simple, cauline, entire, fascicled or opposite on the seed-
