of this seems to be with P. pilosa and gercmioefoUa. Tbe barren fronds in size and
cutting mucb resemble tbose of tbe former.

Hab. Tropical America, from Guatemala southward to Brazil and Peru ; Polynesian
Islands from New Caledonia northward to the Neilgherries, N. China, and Subtropical
Australia, Mascaren Isles, Zambesi Land, Angola, and Cape Colony.—This and the two
preceding agree in habit with Ptexis pedata and Cheilanthes Kirkii. From the former
their simple veins furnish the readiest mark of distinction. The plant from Australia,
sent by Dr. Mueller, gathered at Rockhampton by Messrs. Tliozet and Dallaohy, is not
unlikely distinct. I t has fronds not more than 1 in. each way, resembling closely in
cutting and texture the barren fronds of the preceding.

which the upper ones are entire and the lower ones larger and sinuated ; lateral
pin næ with the lobes on the upper side nearly entire, but those on the low'er side
prolonged and again deeply lobed, the largest entire divisions about 1 in. deep,
