Tetraplasandra waialealae Rock , Coll. Hawaii Publ. Bull. 1: 10. 1911.
Type information:
Holotype [BISH]. J. F. Rock 8870. 20 October 1911. Kaua`i: [summit of] Wai`ale`ale.5000ft. Isotype(s) [A [2], BISH! [2], GH [3], K!, L, US!].

Note: RKS examined specimens at BISH. Sherff's comments (Fieldiana, Bot. 29: 73. 1955) could be taken as a lectotypification, but if so, the lectotypification is superfluous. Rock's choice of type is clear from the protologue, he wrote "type" on one of the specimens, and he illustrated the specimen that he labeled as type.
