A rare fern.—Mr. John Spence, of Santa eke recently prom a 
rare fern in the high mountain regions of Santa Barbara county, which appears 
to be a South American Notholena, N. tenera Gill., not heretofore reported in 
the United States except in a single locality in Southern Utah. In form and 
manner of growth it resembles Notholena nivea Desv. (See Hooker & Baker’s 
“Synopsis Filicum ” p. 374.) As N. nivea is placed under the subdivision 
Cincinalis, ba Livoipa by the fronds being coated with white or yellow pow- 
der, and th e specimens show no trace of cae og kor ies —. be placed un- 
der the sidivhehie Eunothochlena, in whi beneath, 
and under the specific name given above, a fern found in the Andes of Bolivia 
and Chili, which the best authorities (see Sir J. W. Hooker’s Species Filicum, 
vol. 5, p. 112) state is a very doubtfully distinct species from N. nivea, from 
which it differs only in the absence of the powder beneath. 
D. C. Eaton in his “ Ferns of North America” figures N. tenera found 
in Southern Utah, but the plate is too poor to give a correct idea of the species, 
and the author expresses a doubt as to the correctness of the determination. 
comparing Mr. Spence’s specimen with a specimen of N. nivea in my 
collection (also a South American species, not reported in the United States 
until found by Prof. Lemmon in Arizona in 1883), I find the resemblance com- 
plete, except that the Californian specimen shows no trace of powder on the un- 
der side of the frond, which corresponds with the N. tenera of H. & B. The 
pinne less distant may be the result of climatic differences. 
Tn absence of further evidence Mr. Spence’s discovery may, with reason- 
able case. be called Notholena tenera. 
Meavids also found a rare form of Aspidium munitum in the same 
locality. .—Lorenzo G. Yates, Santa Barbara, Calif.
