Series Longipetalae (Diels) Lawrence

Series Longipetalae (Diels) Lawrence A group of plants within the section Limniris from Western North America with persistent fruiting stems (into 2nd year) a 2-toothed stigma, and capsules with six ribs and tapering at both ends; Diels in Engl. & Prantl, Nat. Pflanzenfam. Aufl. (1930); G.H.M. Lawrence in ‘A reclassification of the genus Iris' in Gentes Herbarium 8:346 (1953), New York. Noted as Longip. in registrations. Generally it is agreed that there are two species, (BIS Species guide only recognizes I. missouriensis) but the varieties and forms seem confused.
Iris longipetala Herbert
Iris missouriensis Nuttall

A third species is listed here but it is unclear where it should be placed.
Iris pariensis Welsh
