Amarylloidinae

Amarylloidinae is a now obsolete informal name for an "infrafamily" within the Amaryllidaceae (Amaryllis) family, erected by Hamilton Traub. This grouping was designed to fill a perceived gap between the formal rank of subfamily and tribes. In his treatment of this family, he divided it first into four subfamiles. Within subfamily Amarylloideae he then divided his sixteen tribes into two infrafamilies, Amarylloidinae (12 tribes) and Pancratioidinae (4 tribes),^[1] both of which were subsequently demonstrated to be polyphyletic,^[2] and hence were abandoned by Dahlgren, who used no rank between family and tribe. On the other hand, he also used a much more restricted Amaryllidaceae corresponding to Traub's subfamily Amarylloideae. Thus Traub's Amarylloideae most closely resembles subfamily Amaryllidoideae sensu APGIII.^[3]

Of these infrafamilies, the smaller Pancratioidinae represents the Andean clade of Amaryllidoideae sensu APGIII, together with the Pancratieae from the Eurasian clade, hence the paraphyly. For a table of Traub's infrafamilies and tribes, and their subseqquent disposition, see Subdivision of Amaryllidoideae.
