Arthropodium

Description

Leaves basal, linear to lanceolate, gradually expanding towards the base to form (apparently dry and membranous) open sheaths, sometimes ciliate or with bristles along the margins; Inflorescence a raceme or panicle. Ovary superior, sessile, subglobose to ellipsoid, 3-celled; Capsule dehiscing loculicidally; Seeds angular.

Madagascar (1 sp.), New Zealand (2 spp.), New Caledonia (1 sp.), and c. 9 spp. in Australia, of which one extends into Malesia: New Guinea (South Papua).

Notes

Payens (1957) made a strong case for combining Dichopogon with Arthropodium. Nevertheless, authors (e.g. ) have continued to separate these genera principally on whether the papillose or pubescent staminal appendages are adnate to the filaments (in Arthropodium) or to the anthers (in Dichopogon). An examination of species represented at Ley den and Adelaide has convinced me that these two genera cannot be separated. A particularly significant form is A. neo- caledonicum in which the appendages are attached to both filaments and anthers such that it would be difficult to assign this species to a genus. In most of the material of Dichopogon the appendages are also distinctly adnate to the filaments as well as to the anthers. Dichopogon strictus and Arthropodium capillipes, although placed in separate genera, have almost indistinguishable stamens.
