Cheilanthes undulata Hope et C. H. Wright, Gard. Chron. III. 34: 397 (1903) 
Rhizome short, oblique, densely radicose; scales at the apex dense, narrowly 
lanceolate, black, rigid; fronds subcespitose, stipe 20-30 cm long, ebeneous or 
dark castaneous, terete, except a narrow groove above, densely clothed from the 
base upward and throughout the flexuose rachis in fine, reddish-brown, appressed 
articulated hairs, which also cover the both sides of leaves, lamina elongate- 
deltoid, 20-35 cm long, 7-15 cm broad at base, tripinnatifid; pinne 6-10-jugate | 
under the deltoid, pinnatifid apex, alternate, horizontally patent, or the lower 
ones more or less deflexed, all petiolate, the basal ones much the largest, 8-10 cm 
long, 5 cm broad, elongate-deltoid, on petiole 1 cm long; pinnules 4-5-jugate, alter- 
nate, broadly deltoid, shortly petiolulate, 2.5 cm long, 2 cm broad, base truncate, 
horizontally patent, pinnatifia to a short distance from costule into 2-4 pairs of 
obleng-lanceolate, blunt segments, of which the basal ones 1 cm long, 2-2.5 mm 
broad; texture herbaceous. brownish underneath, greenish above; veins flabellu- 
lately forked, very oblique to the flexuose costule of segment; indusium narrow, 
brown, continuous, crenate, ciliate.

One of the most distinct endemic species of the genus, with which Ch.’ 
Delavayt Baker from the same locality is the only close relative, which differs in 
rachis and rachilets being not flexuose, glabrous surfaces of leaves and decidedly 
cordate pinnuies. It appears fo be a common fern in the north-western part of 
Yunnan, but not known elsewhere, besides Wilson’s plant from western Szechwan.
