FIG. 554. Linaria Cymbalaria, x 40. A, longitudinal section of seed. B, trans- 

 verse section of seed: .S, radicle; P, endosperm; OT, testa; IT, tegmen; 

 Cs, cotyledons ; H, hilum. 



Seeds oval or globose-oval, deeply ridged and furrowed longi- 

 tudinally with a very thick testa, 1 mm. long, '75 mm. in diameter. 



Embryo. The cotyledons with their edges vertical to the axis, 

 out varying apparently according to the position of the seed in the 

 capsule. 



Seedling (fig. 555). 



Primary root slender, flexuose, with very fine lateral rootlets. 



Hypocotyl decumbent, subflexuose, thinly pubescent, tapering 

 indistinguishably into the root, not giving rise to adventitious buds. 



Cotyledons rather unequal, thinly pubescent, pale green, rotund 

 or subreniform, mucronate, entire, 4*5 mm. long, 5 mm. wide ; 

 petiole thinly pubescent, channelled above, about 7-9 mm. long.
