Dubautia laxa Hook. & Arn. var. bryanii Sherff, Amer. J. Bot. 20: 617. 1933.
Type information:
Holotype [F]. C.N. Forbes and C.M. Cooke s.n.. 3-8 May 1909. O`ahu: Koolauloa Mts., between Punaluu and Kaipapau. Isotype(s) [BISH! [3], BM, F!, GH!, K, MO!, NY!].

Note: G. Carr (Allertonia 4: 69. 1985) erroneously published the holotype as being at BISH. Sherff clearly stated that the type was at F, and the BISH sheet annotated by Carr as the holotype has "cotype" written on the label.
