Adiantum philippense

The species was named by Carl Linnaeus in 1753. It was lectotypified by R.E.G. Pichi-Sermolli in 1957 based on an illustration by James Petiver. The identifiability of this illustration was disputed, leading some authorities to deprecate A. philippense as a nomen dubium and use the next available name for the taxon, Adiantum lunulatum Burm.f.. Burman conferred this specific epithet based on its half-moon shaped pinnae. However, Christopher Fraser-Jenkins located the original material and drawing of the lectotype sent to Petiver by Georg Joseph Kamel in the Sloane Herbarium, making clear the application of the name A. philippense. == Description ==

Adiantum philippense grows in a creeping or semi-erect position. Its fronds are arched and tufted. The fern is notably overall very glabrous and smooth. It grows on streambanks, often on rocks in forests and woodland. ==Distribution==

Adiantum philippense can be found across south-east Asia. It inhabits tropical areas in Bangladesh, India, Nepal, Thailand, and Cambodia. ==Gallery==
