Type Information
Stenogyne rugosa Benth. var. subulata Sherff, Bot. Gaz. (Crawfordsville) 96: 142 1934.
Hawai`i, between Kilauea and Kapapala. 1851- 1871. Hillebrand s.n..
Holotype [B].
Note: BISH sheet annotated by St. John "apparent isotype" is not considered an isotype by WLW. Sherff did not cite a BISH sheet and his locality citation is slightly different from that on the specimen label ("vicinity of Kilauea"). The specimen does not fit the description given in the protologue, and appears to be a mixed collection (at least from different plants, even if from plants of the same species).

Stenogyne rugosa Benth. var. imberbis H. St. John, Phytologia 63: 168 1987.
Hawai`i, s.l.. Bailey s.n..
Holotype [BISH].

Note: No date, collector, or locality. Handwritten on the sheet are "Probably came from Maui," C.N. Forbes and "Probably came from Hawaii," E.E. Sherff. Publication gives "Hawaii I." for locality. Label says "from the herbarium of E. Bailey," so we are assuming E. Bailey was the collector. There is no E. Bailey in the Index Herbariorum collector index. St. John annotated this sheet as the holotype.
