This very distinct species is named after the collector, J. N. Rose, 

 Ph.D., Assistant Curator of Botany in the Smithsonian Institution, 

 Washington, U.S A. The drawings were made from specimens lent 

 by that institution, through the courtesy of the Secretary, Mr. S. P. 

 Langley. It is remarkable for the marginal tentacle-like bristles of 

 the leaves, a character it has in common with the closely allied South 

 African genus Alepidea. — W. Botting Hemsley.
