RESURRECTION OF THEMIDACEAE FOR THE BRODIAEA ALLIANCE, AND RECIRCUMSCRIPTION OF ALLIACEAE, AMARYLLIDACEAE AND AGAPANTHOIDEAE

The family Themidaceae Salisb. is resurrected and recircumscribed. It consists of c. 10 genera of cormous plants principally from western N. America (British Columbia to northern Guatemala). These had been incl uded in Alliaceae, as tribe Brodiaeeae (subfamily Allioideae), but rec ent molecular and anatomical studies indicate that the group merits fa milial status. Petronymphe is not a member of this group but rather be longs in Anthericaceae. Agapanthus is misplaced in Alliaceae and, desp ite its superior ovary, should be considered a member of Amaryllidacea e, as subfamily Agapanthoideae. Alliaceae, Amaryllidaceae, and Agapant hoideae are recircumscribed, and Tulbaghieae raised to subfamilial sta tus.
