270 de Fr nine . — The Morphology and Anatomy of the 
of a typical bifacial leaf form. Also under cultural conditions the leaves 
tend to be more erect in position. 
Text-fig. 19. Transverse sections of part of the leaf blade of S. binervosa (a-p. x 235), and 
of S. bellidifolia (e. x 220). A, narrow-leaved lateral plant ; B, sand plant; C, culture from seed 
plant ; D, broad-leaved form ; e, .S’, bellidifolia. 
Comparison of Text-fig. 1 9, A. D and E, again brings out the intermediate 
character of the leaf of the broad-leaved plant, for both it and bellidifolia 
are bifacial in type.
