CHARACTERS OF TRIBES AND GENERA, : 
2 Ons.— The yellow farina characteristic of this species 
seems to indicate its affinity to be with Cheilanthes auran- 
tiaca and C. chrysophylla, but its rudimentary indusium 
required it to be placed under the present genus.

Cheilanthes sp. auct. ; Hook. Sp. Fil. 
Vernation fasciculate, ceespitose, acaulose, rarely sarmen- 
tose. Fronds 4 to 18 inches high, bi-tri-quadri-pinnatifid, 
pilose, squamiferous or viscose, ultimate segments minute, 
generally orbicular or cuneiform, concave, the margin 
membraneous, revolute, conniving, forming an universal. 
cucullate indusium. Veins forked, free. Receptacles ter- 
minal, Sporangia few, confluent under the universal 
indusium.

. Oss.— Presl was the first to indicate this as a distinct ` 
group of Cheilanthes, under the sectional name Physapteris, 
 &nd Pie afterwards characterised it as a separate gen 
under the name here adopted. This genus consists of 
about twenty species, distinguished from Nothochlena and 
Cheilanthes by their small, concave, lenticular segments. 
_ They are natives chiefly of the Andean regions of America, 
7 . extending to the Rocky Mountains in the North. e:
