A good deal like tlic last, but easUy distinguishable by its less membranous leaves, 

 which are more narrowed at the base, by its much shorter racemes, which are often 

 quite concealed by the sheathing bases of the leaves, and by the much smaller 

 flowers. There is an extensive series of specimens of this species in the Hookerian 

 Herbarium, from which we learn that it flowers in its first year, and that in young
