A New NortrHoLaENA 109 
Ber. Mt.” Of the several collections the specimen se- 
lected as the type is by far the largest and best pre- 
served. 
Of Notholaena tenera specimens are in the National 
Herbarium from Argentina (Cordoba, Kuntze), Bolivia 
(Rusby 326, 327), and Peru (Wilkes Exped. 4, Safford 
992, Rose 19471), all from the high mountains, up to at 
_ least 3000 meters. From these N. Jonesii differs con- 
stantly in its much lower stature and its depressed- 
spreading habit, in its very much more slender, long- 
attenuate rhizome scales, in its reddish brown (not 
purplish black) stipe and rachises,.in having the blades 
bipinnate with only the major pinnules of the larger 
pinnae deeply lobed or divided (as opposed to the sub- 
tripinnate blades of N. tenera), and in the orbicular to 
subcordate (not elliptical to oval) form of its pinnules, 
these attached to the secondary rachises by short flat- 
tish, greenish brown stalks in contrast to the slender, 
terete, purplish black stalks of N. tenera. The dark 
wiry rachises throughout give N. tenera the appearance 
of a much more slender and delicate plant than N. 
Jonesii, despite its far greater size. 
Apparently N. Jonesii is extremely rare and not often 
collected. It seems to be a pronounced xerophyte and 
will probably not be found far from the area within 
which it is now known. As N. tenera, it has been reported 
from Arizona. The California localities, including at 
least two not mentioned above, have been discussed 
interestingly by Mr. 8. B. Parish.*
