(synonym of Cheilanthes intertexta)

coastal lipfern

Stems

ascending or shortly creeping in rock crevices; much-branched and forming a caudex;

scales dense and persistent, mostly bicolored with a well-defined; dark; central stripe and pale narrow margins.

Leaves

short; seldom over 15 cm, produced in clusters from the caudex; non-circinate when young.

Petioles

slender; up to about half of the leaf length;

petiole and rachis dark brown, with a sparse indumentum of hairs and scales.

Blades

(broadly) lanceolate; up to about 8 × 3 cm, 3-pinnate;

pinnae on proximal half of blade more or less equal in length;

distal pinnae reduced in size apically.

Ultimate segments

oblong; convex, dark green; bead-like; and more or less glossy adaxially; concave, red-brown; and almost bowl-like abaxially with the leaf margin strongly recurved and arching; the edge thin and white, forming a false indusium; abaxial indumentum very dense, red-brown, extending to the leaf margin, composed of multilayered small scales and branched hairs;

scales graduated; those appressed to the leaf surface deeply divided into narrow segments; outer scales narrowly ovate;

margins ciliate near the base; adaxial leaf surface glabrous or with sparse hairs and scales.

Sporangia
