 This is the Oxalis decaphyllaoi Gray and of all American writer.-. It differs greatly' 



from the material from the Valley of .Mexico in the texture of the hull) scales ami in 

 having numerous veins instead of three. 1 have referred tentatively to this species 

 all the material heretofore passing under 0. <h c<ii>}i>ill<< except that from the Valley
