138 Dowell : New ferns described as hybrids 



with some thick dark-brown elongated scales ; blades pinnate 

 pinnatifid, acuminate, the sterile triangular-ovate to ovate-lanceo- 

 late, 20-50 cm. long, 15-25 cm. wide, fertile blades ovate-lan- 

 ceolate to oblong-lanceolate, narrowed at the base, 40-80 cm. 

 long, 20-35 cm - wide; pinnae deeply incised, sometimes divided 

 at the base, ovate-lanceolate to oblong-lanceolate, acuminate, in 

 some fronds the upper broadest at the base while the lower are 

 narrowed at the base, in other fronds the lower broadest at the 

 base while the middle and upper ones are broadest near the mid- 

 dle ; pinnulae or lobes of the pinnae 10-20 pairs, oblong to 

 oblong-linear, obtuse or acutish, falcate, appressed-serrate or 

 those of the lower pinnae slightly incised ; sori near the midvein, 

 indusia thin, glabrous. 



In general appearance this fern resembles the Clinton fern, 

 with which it has been placed by some, while others have referred 

 it to the Goldie fern. It differs from the former in having some 

 of the thick dark-brown scales characteristic of the latter, and in 

 having some of the pinnae narrowed at the base. 



It differs from the Goldie fern in having fewer of the thick 

 dark scales ; the fronds usually more narrow, more gradually 

 tapering, and more narrowed at the base; the basal pinnulae 

 longest on a portion of the frond, the upper in some, the lower 

 in others.
