N. anceps, DC. — The subjoined description of this species, or 

 variety, which we have not seen, is from Grenier and Godron^ s 

 * Flore de France,' vol. i. p. 98. " This plant is distinguished 

 from iV. sylvestre, its near relation, by its larger flowers, thicker 

 stigma, and especially by its linear-oblong indistinctly compressed 

 (comprimees, ancipitees) pods, which are shorter than the pe- 

 duncles, by its larger usually auricled leaves, and by its more 

 robust growth.^' — Grows in the same places as the preceding. 



Per. ; June-August.
