_ We have not seen authentically named specimens of this species ; and Bourgeau’s 
specimens we have determined from Schlechtendal’s description. It may be the same 
as De Candolle’s D. linearifolium, imperfectly described in the ‘ Prodromus.’ It differs 
from the plant named D. angustifolium, DC., in the Kew Herbarium (to which, however, 
it is closely related), in the primary lateral veins being broadly curved instead of being 
straight and forming very acute angles with the midrib, also in the pod usually having 
four or five joints instead of six or seven.
