Selaginella barrancae n. sp. 
La barranca Guadalajara Jalisco, Nov. 25 1930. Growing loosely 
matted, in moist places in the shade, Leaves flat, almost round, 
about 2mm. long, smooth, slightly imbricated at least above, 
marginless and mostly blunt, but some «f the upper white-apiculate 
the 1orming fertile spikes seemingly short and with imbricated 
and apiculate leaves. This would at first suggest §. saccarata, 
but leaves decidedly different. : 
ellwa intromarginalis, of authors. Judging from herbarium 
material, there is a great variation init. In yonng fronds the in- 
dusium is beautifully fringed and lacerate, and in older ones it is 
split up as in Cheilanthes, In Manzanillo material of my own 
Polypodium Scouleri H. & G. Jepson, Man. 29, says this has 
evate fronds with oblong pinnz. 1 find the fronds are normal! y 
lanceolate, and rarely ovate, and from a few inches to a foot long, 
and with stalks as long as thefronds, The freshly ripe fruit dots 
ure lemon-yellow, very large and in age becoming blackish. The 
pinne are rarely oblong, but normally nsrrowly oblong to almost 
linear and obtuse and very obscurely and obtusely dentate. The 
root scales are the same as in P. Californicum, that is, chestnut- 
maria spicant Desv. Jepsonl. c. 34 says ‘Leaves erect! 
(meaning sterile ones). I find the sterile ones are normally flat on 
the ground, while the fertile ones are strictly erect from a central 
tuft.
