I eannot but regard the form described as H. Jussicxii in the Niger flora with the wing 

 of the samara, " produced equally above, below, and outwardly," as belonging to the original 

 species of Jussieu. Vogcl's fruits appear to be scarcely mature, and in other respects — 

 foliage, flower, and inflorescence — there is no ditfereuce. In a specimen frouj Prince's 

 Island, some of the leaves, upon a lateral shoot, are remarkably triplinervcd.
