Embryo small, less than half the length of the endosperm,

Primary root slender, flexuose, soon exceeded in length by the 

 lateral rootlets. 



Hypocotyl short or indistinguishable from the root. 



Cotyledons small, ovate, obtuse or subacute, petiolate, glabrous ; 

 lamina 2*5 mm. long, 2 mm. wide ; petiole grooved above, '5 mm. 

 long. 



Stem shrubby, erect, terete, pubescent in the seedling, glabrous 

 in the adult plant, pale green, shining ; 1st and 2nd internodes 2'5- 

 4 mm. long ; 3rd 2'5 mm. 



Leaves simple, cauline, opposite, decussate, exstipulate, petiolate, 

 glabrous and shining on both surfaces, coriaceous, evergreen, deep 

 green above, pale beneath, obscurely alternately penninerved and 

 reticulate ; petioles short, grooved on the upper side, semiamplexi-

First pair lanceolate-elliptic, obtuse, entire. 



Second pair lanceolate-elliptic, entire, subacute. 



Third pair lanceolate-elliptic, acute, with one or two serratures 

 on each side. 



Intermediate forms are lanceolate, acute, serrate. 



Ultimate leaves oblong-lanceolate, acuminate, acute or tipped 

 with a mucro, serrulate, minutely pubescent or scaberulous at the 

 margin, as are the intermediate forms, but not those in the younger 

 seedling stage, three- or faintly five-nerved in the lower half.

Hypocotyl short, erect, terete, glabrous, 1-1*5 mm. long, light 

 green or colourless. 



Cotyledons ovate, obtuse, emarginate, membranous, petiolate, 

 glabrous, green, indistinctly one-nerved. 



Stem erect, terete, herbaceous, hairy ; 1st internode -75-1 mm. 

 long ; 2nd shorter. 



First leaves simple, cauline, opposite, decussate, broadly ovate, 

 obtuse or subacute, serrate, hairy, petiolate, exstipulate, light green, 

 distinctly and alternately pinnatinerved. 



Veronica sp. (V. hedersefoliae aff.).
