Douropteris alvarezii P.Correia, Šimůnek, C.J.Cleal et A.A.Sá

Original diagnosis/description

Frond at least bipinnate bearing pinnules of variable shape and size. Pinnules spaced, marginally non‐decurrent, and slightly retracted at the base; large and lobate to pinnately lobed at the lower part of pinnae tapering gradually towards smaller and non‐lobed or entire margined pinnules at distal parts of the pinnae. Lobate pinnules with generally poorly lobed margins and prominent basal lobes, having one remarkably more developed basal lobe. Midvein very broad and basally decurrent. Lateral veins very irregular and strong, with various ramified veins entering each lobe of lobate pinnules. Intercalated pinnules absent.

Etymology

Named after the Douro Basin.

Notes

Date of publication: Following Art. 29 and 30 of ICN, the date of publication is date of "Version of Record online", as it is clearly stated on the journal web site that "Early View articles are complete full-text articles published online in advance of their publication in a printed issue. Early View articles are complete and final. ... Because they are in final form, no changes can be made after online publication." This fulfills the requirements of ICN for effective publication (see especially ICN Art. 30.3, Ex. 5).
