364 BROADHURST: STRUTHIOPTERIS IN NORTH AMERICA 
The above incomplete description has been rearranged from 
Christ’s with some few additions based on von Tiirckheim’s 
specimens. The fertile frond forming part of von Tiirckheim’s 
no. 353 is somewhat mutilated; the two specimens afford the fol- 
lowing additions: 
Fertile frond 130 cm. long; stipe 60-68 cm. long, light, blotched 
with brownish, the scales few, yellowish brown; lamina 65-80 
cm. long, the pinnae distant; pinnae 16—24-jugate, 13-16 cm. long, 
4-5 mm. wide, heavy, with a sterile apex 1-5 mm. long, the bases 
decidedly cordate; sporangia yellowish brown or dark brown; 
indusium wavy and entire or irregularly broken, less lacerate than 
in most of the petioled species. 
Christ kindly sent one sterile pinna of S. costaricensis. It 
was evidently one of the upper ones, measuring 10 cm. by 13 mm.; 
the color is not yellow as in S. Werckleana, but a light gray-green 
characteristic of recent specimens of S. polypodioides and common 
to several of the heavier species of Struthiopteris; the vein spaces 
vary from 16 to18torcm. |

Lomaria danaeacea Kunze, Linnaea 18: 326. 1844. 
Blechnum danaeaceum C. Chr. Ind. Fil. 153. 1905. 
Rhizome oblique, very paleaceous with reddish scales. Sterile 
fronds 10-40 cm. long; stipes clustered, 4-15 cm. long, wi 
pressed scales which are larger toward the rhizome; lamina a 
cm. wide, short ovate-oblong, not gradually reduced above, the 
terminal pinna largest, 6-9 cm. long, often with a asal lobe, 
shining, lighter below; pinnae 2~-5-jugate, ovate-lanceclate . 
ovate-oblong, the apex serrate, the base rounded, unequally nod 
cuneate, free throughout, sessile, the lower pinnae short-petiole : 
4-7.5 cm. long, 1.5-2.5 cm. wide; margins revolute; leaf tissue mee 
ceous;* costae raised below and chaffy with appressed scales; vffy 
close and distinct. Sporophyls with light-colored, sparsely € ; ne 
stipes; pinnae curved, numerous, long (12-15 cm. in parts 0 if 
fertile laminae seen in Kew and Geneva), the apex sho 
acuminate.
