Key to the genera of species traditionally placed in the genus Doryopteris

1. Two vascular bundles at the base of the petiole (best seen close to the insertion with the rhizome); scales of rhizome and petiole bases linear to linear-lanceolate; lamina varying from simple, entire to 3-lobed, pedate to pedate-pinnatifid to 2-pinnatifid; venation pattern predominantly free (except L. ornithopus ) .......................................................................................................... Lytoneuron

-. One vascular bundle at the base of the petiole; scales of rhizome and petiole bases varying from ovate-lanceolate to long-lanceolate; lamina dissection diverse, from sagittate, pedate to pinnate; venation pattern commonly anastomosed, few species with veins free and/or partially anastomosed ............................................................................................................................................................ 2

2. Rhizome erect to sub-erect, short to long and/or slightly decumbent; scales of rhizome and petiole bases clathrate, varying from lanceolate to more or less ovate-lanceolate; lamina sagittate to pedate, pedate-pinnatifid to 3-pinnatifid ................... Doryopteris

-. Rhizome short to short-creeping; scales of rhizome and petiole bases variable, clathrate to non-clathrate and varying from lanceolate to long-lanceolate (rarely lanceolate-ovate); lamina 1-pinnate to 3-pinnate ................................................................... Ormopteris
