exstipulate), petiolate, deep green, glabrous above, ciliate at the 

 margin, thinly hairy or in young specimens sometimes glabrous 

 beneath ; petioles semiterete, channelled above, thinly hairy ; 

 stipules subulate, obtuse or subacute, membranous, thinly hairy, 

 whitish in seedlings, absent on first leaf. 



Nos. 1 and 2. Reniform, five-nerved, irregularly crenate or 

 incipiently three- to five-lobed. 



No. 8. Cordate, more decidedly five-lobed. 



Ultimate leaves palmately seven-nerved ; radical ones reniform 

 or orbicular with a wide sinus at the base, irregularly crenate or 

 incipiently lobulate ; lower cauline ones more or less deeply lobed 

 (generally from one-quarter to one-half their radius) ; lobes broad, 

 oblong, and again lobulate and subacutely toothed ; upper cauline, 

 seven-lobed nearly to the base larger lobes rhomboid, pinnatifid, 

 and acutely toothed, with alternate ascending nerves. 



The cotyledons of M. sylvestris and M. rotundifolia resemble 

 those of M. moschata, but in those I have seen the notch near the 

 apex was somewhat less marked.

Hypocotyl erect, terete, glabrous, 5-10 mm. long, light green 

 or colourless. 



Cotyledons unequal, membranous, rotund-cordate, slightly 

 emarginate, obtuse, cordate at the base, petiolate, with rather long 

 petioles, glabrous, light green, distinctly trinerved. 



Stem with primary internodes undeveloped. 



First leaves simple, radical, alternate, petiolate, stipulate, cordate 

 at the base, subrotund, crenate, palminerved, covered with fine

 small and deciduous. 



Navaea phoenicea, Webb et Berthelot. 



Hypocotyl erect, terete, pubescent, 2-3 cm. long, light green. 



Cotyledons unequal, cordate or elongated, ovate and cordate at 

 the base, subacute, entire, petiolate, covered with minute hairs, 

 green, five-nerved ; petiole unequal, channelled on the upper side, 

 hairy.
