Nomenclature
Scientific Name:
Astelia microsperma Colenso, Trans. & Proc. New Zealand Inst. 17: 251 (1885)
Synonymy:
  • Collospermum microspermum (Colenso) Skottsb., Kongl. Svenska Vetensk. Acad. Handl. Ser. 3, 14: 82 (1934)
Type: NEW ZEALAND. North Island. Seventy-mile Bush, between Norsewood and Danniverke, County of Waipawa. 1884, W. Colenso s.n. (Lectotype: K [000524879, digital image!], fruiting material in packet, designated by Skottsberg, 1934, 81).
  • = Astelia albicans Colenso, Trans. & Proc. New Zealand Inst. 17: 252 (1885)
Type: NEW ZEALAND. North Island. East slopes of Ruahine mountain range, county of Waipawa. Jan. 1884, A. Hamilton s.n. (Syntype: K [000524880, digital image!], staminate, pistillate). Skottsberg (1934, 88) identified a single specimen at K as the type material and the specimen in his plate 20 (K000524880) is consistent with the specimen described as the type. As Astelia is dioecious, the inclusion of one staminate and one pistillate inflorescence on the specimen means that it represents two distinct collections and each is rendered a syntype.

Type: NEW ZEALAND. North Island. Woods, hilly country north of Napier, County of Wairoa, 1886, A. Hamilton s.n. (Lectotype: K [000524881, digital image!], pistillate, designated by Skottsberg, 1934, 85).
