Angiopteris guangdongensis (Marattiaceae): A New Species From Guangdong, China.

ABSTRACT: In this study, we confirm that the population of Angiopteris from Guangdong Province represents a distinct new species, which we describe as Angiopteris guangdongensis. Morphologically, A. guangdongensis resembles Angiopteris fokiensis but can be distinguished by its arborescent habit (reaching up to 5 m in height), robust scaly stipes, linear-lanceolate pinnules, abaxially scaly slender pinnules, sori with 7-16 sporangia, and a higher basal pinnule aspect ratio. Plastid phylogenomic analyses place A. guangdongensis as a monophyletic lineage sister to A. fokiensis. According to IUCN guidelines, the species is preliminarily assessed as 'Data Deficient (DD)'. In addition, we report the complete plastid genome of this new species. This discovery not o
