SPECIMENS EXAMINED: Maui, Robinson 723 V; Oahu, Douglas

The darker color, and proportionately broader form distinguish 
this from S. Springiz, notwithstanding the close relationship exist- 
ing between S. Menziesti, S. flabellata, and S. Springit.

Baker (Fern Allies97. 1887) and Hieronymus (Nat. Pflanzen- 
fam. 14: 678. 1901) both speak of the intergrading forms between 
S. Springii and S. Menziesii. The latter, however, recognizes 
S. Springii as a species distinct from S. Menziesti though closely 
related to it. It would not be remarkable if crosses had fre- 
quently occurred between these two forms which grow upon wet 
rocks where there is every facility for such hybridization. 
The teeth at the base of the anterior margin of the stem 
leaves are longer than those of the apical portion, but hardly 
slender enough to be regarded as cilia as Gaudichaud figures them. 
SPECIES INQUIRENDA 
SELAGINELLA PARVULA Hilleb. Fl. Haw. Is. 648. 1888 
TYPE LocaLity: Hawaiian Islands. 
DistripuTion: Oahu (Nuuanu Valley), Hawaiian Islands. 
Hillebrand in a footnote to his description of S. parvula suggests 
that it may be a young form of S. arbuscula, a suggestion which 
seems very probably true, from the close similarity of the two 
plants and the fact that only the one collection of the material 
has been made. .
