This is the species wrongly referred by Brackenridge (Fil. 
U.S. Expl. Exp. 302. 1854) to S. australis Gaud., a plant from 
the Falkland Islands, described by Gaudichaud (Ann. Sci. Nat. 
5:98. 1825). 
Heller (Minn. Bot. Stud. 1: 789. 1907) says: “The first 
specimens were collected at an elevation of perhaps 762 m., on 
Konahuanui, Oahu, on a little spot in clay formation. The 
plants were small and stunted. It was found on the opposite 
side of the valley on the slope of Waiolani, at the same elevation. 
Near the Wahiawa bog, on Kauai, large and beautiful specimens 
were obtained.” Mr. C. N. Forbes’ specimen (Forbes 1038 BM) 
collected at the extreme western ridge of Konahuanui, “a dry 
ridge in broad sunlight,” is small and stunted though it has de- 
veloped sporangia, while specimens from the Wahiawa bog above 
McBride’s mountain house (Robinson 419 V and 452 V) are large 
and fine. 
2, GLEICHENIACEAE 
Terrestial, xerophilous plants, with erect or creeping roe 
stocks. Leaves non-articulate, distant or cespitose, mostly 
consisting of an erect or ascending primary leafstalk of indeter- 
minate growth, forking into one to several opposite divisions, 
these simple and determinate or one to several times dichotomous 
Sori dorsal or terminal upon the veins, non-indusiate; sporangi? 
sessile, subglobose to pyriform; annulus nearly complete, obliquely 
transverse; dehiscence vertical. . 
The family Gleicheniaceae is represented by several specie? 
e 
of the genus Dicranopteris, which form nearly impenetrabl
