STICTOLEJEUNEA 
The genus Stictolejeunea is so clearly defined among the Ze- 
Jeuneae that even Spruce was almost willing to accord it generic 
rank. It includes two species only, the variable S. sguamata 
(Willd.) Schiffn. and S. Kunzeana (Gottsche) Schiffn. Both of 
these species are widely distributed in the American tropics, S. 
squamata occurring on the plains and at low elevations on the 
mountains, while S. Kunuzeana is restricted to somewhat higher 
altitudes. S. sguamata, which must be regarded as the type of the 
genus, has also been recorded from the East Indies and from the 
Hawaiian Islands. The first of these records is based upon the 
original specimens, which Weber received from Willdenow. These 
are labeled, “in corticibus Ayrti caryophyllatae ex Ind. orient.” 
Portions of the original material have been examined by Stephani * 
and also by Schiffner,} both of whom pronounce it identical with 
the American plant. The species is also listed by Mitten f from 
the East Indies, but solely on the authority of the original record. 
Since the plant has not recently been collected in these regions, in 
spite of its striking character, it is possible that there was an error 
in the original label. There is also much doubt in regard to the 
specimens from the Hawaiian Islands, and it is probable that this
