 necessary comparisons, and am therefore able to present the proposed 

 species and to discuss their relationships with more confidence than 

 would otherwise have been possible.

 related to Z. pauiculatus (Nutt.) Wats., to which it has been referred 

 by some of those wlio liave collected it. Init differs in its widely spread-
