Type Information
Basionym: Tetraplasandra waialealae Rock , Coll. Hawaii Publ. Bull. 1: 10 1911.
Kaua`i, [summit of] Wai`ale`ale. 5000 ft. 20 October 1911. Rock 8870.
Holotype [BISH]. 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.
