Abstract:

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 celebrate

his 80th. birthday last year.
