rudiment. In these circumstances it appears necessary to divide 
the genus Schoenoxiphium into two subgenera which may be 
characterised as follows : 
A. Galpinia Kiikenthal—Spicula unica terminalis ebracteata. 
Spiculae partiales demum divaricato-reflexae, Squamae 
caducae.. 
B. Eu-Schoenoziphium Kiikenthal.—Spiculae plures spicatim 
vel paniculatim dispositae bracteatae. Spiculae partiales 
oblique patentes. Ratuinst persistentes.
