Dryostachyum Hieronymi Brause, Engl. Jahrb. 49:55. var. lati-
pinna n. var.

A typo differt: pinnis fertilibus 1 cm latis.

Bolaang-Mongondou, rain-forest above Modajag near Danau-lake
(no. 52). |

I have had much doubt if I should refer this form to D. pilosum
J. Sm. or to D. Hieronymi; in its broader fertile pinne it resembles |
Ihe former, in pubescence and glabrous sporangia the latter; it is.
possible that D. Hieronymi is a variety of D. pilosum, it is new to
Gelebes. |
