Chieniopteris Ching, A New Fern Genus from China

 A new fern genus, Chieniopteris Ching, based upon  Woodwardia  harlandii Hook. from South China, is here proposed.  Its systematic position seems to be apparently inter- mediate between Lorinseria Presl of the east North America and Woodwardia  Sm.  of the Old World, from the former the genus is distinguished by its upland habitat, by the uniform fronds of chartaceous or rather subcoriaceous texture  with  straw-colored stipe and rachis of the leaves; from the latter by the long  creeping  rhizome with  distant fronds, by the simple trilobed or generally simply pinnate lamina with a few pairs of entire or sometimes irregularly lobated lateral pinnae, which are connected at the base by a narrow wing on each side of the rachis, by the superficial and longer sori and by the veins anastomosing between the sori and the leaf margin.      While describing the plant as a Woodwardia, Hooker properly noted that it is very distinct from the oriental Woodwardia japonica (Linn. fil.) Sm. and W. prolifera Hook. Later Baker transferred Hooker's species under Woodwardia sect. Lorinseria in Synopsis Filicum in a juxtaposition with Woodwardia areolata (Linn.)  Moore, the type of the genus Lorinseria Presl.  It is J. Smith, who referred the southern Chinese plant to Lorin- seria Presl, with which it is somewhat similar in habit, but differs in characters diagnosed above, besides a distinct habitat and geographic area.      The new genus is now represented by two species, C. harlandii (Hook.) Ching and C. kempii (Cop.) Ching, all indigenous in South China, extending  southwardly  to  the northern part of Vietnam and eastwardly to the islands of southern Japan.      The new genus is named after professor S. S. Chien, director of the Institute of Botany, Academia Sinica, and president of the Botanical Society of China, to celebratehis 80th. birthday last year.
