Broadhurst: Struthiopteris in North America 375 



barely petioled ; margins incompletely and very narrowly revolute, 

 entire,* not cartilaginous, finely glandular with stalked glands ;f 

 leaf tissue coriaceous, gray-green or sometimes when dried yellow- 

 ish brown, much as in S. Werckleana, the costal scales smaller or 

 lacking; veins not raised, indistinct, not swollen at their apkes, 

 the vein spaces 15 or 1 6 to I cm. Sporophyls 67 cm. long;! stipes 

 18 cm. long; lamina 47 cm. long, abruptly reduced at the base, 

 not reduced at the apex; pinnae 19-jugate, with a sterile apex 1-2 

 mm. long, the base decurrently adnate in the upper pinnae, sessile 

 in the lower ones and rounded to cordate, 9.5-1 1 cm. long, 2-3 mm. 

 wide; sporangia brownish yellow; indusium cartilaginous, fully 

 and regularly lacerate to the base, the sides of the lacerations, 

 concavely hollowed, the edges finely fimbriate. [Plate 27.]

Plants terrestrial. Rhizome at least 2.5 cm. thick, the scales 

 2-3 cm. long, 2-4 mm. wide, varying from dark fawn to burnt 

 umber. Sterile fronds 35-125 cm. long; stipes 15-74 cm. lon g> 

 clustered, angulate, usually light-colored, dull to shining, the 

 scales lighter, otherwise as on the rhizome, very deciduous, fewer 

 shapeless ones among them than in S. lineata or none at all, the 



* Wholly entire; not even subserrately margined by the swollen vein apices. In 

 this 5. Shaferi affords a marked contrast to all the petioled species previously 

 described. 



t Numerous, tiny, stalked glands are found on the revolute margin. Nothing 

 of the kind has been observed in any other specimens included in this paper. This 

 material is fresher than any other seen (collected in 191 1), and this fact may account 

 for the presence of the glands. Conservatory specimens of 5. Underwoodiana, to 

 which S. Shaferi is most nearly related, do not possess similar glands. 



% All of the following measurements refer to the single fertile trond seen.
