FEIGNS OF THE WEST 
Veins mostly with four branches, i to 2 feet high. May run into P. 
vulgare. 
Usually on trees. Northern California and northward. 
* * Fronds divided to the midrib, or very near it ; divisions linear-oblong ; 
veinlets usually forming a net-work, at least near the margin. 
4. P. Califoriliciini, Kaulfuss. (The Californian P.) 
Frond papery, ovate to oblong-lanceolate ; divisions narrowed at 
base, but not stalked, upper ones gradually smaller till they become mere 
teeth at the tip of the frond ; veinlets 4 to 6, the lowest one bearing an 
elliptical or egg-shaped fruit-dot, the upper ones sometimes sending 
branches across to each other close to the margin, making a net-work. 
Varies greatly. (jP. mteimiedmm, H. & A.) 
From Guadalupe Island northward, mostly along the Coast, 
5. P. Scoilleri, Hooker and Greville. {Scouled s P.) 
Fronds very thick, leathery, fleshy when green, broadly ovate ; di- 
visions minutely toothed, blunt, not tapering into the terminal one ; 
fruit-dots very large (often one-fifth inch in diameter), near the midrib ; 
veinlets forming a series of meshes all along the margin. (P. carnosum, 
Kellogg; P. pachyphy Hum, Eaton.) 
On stumps and trees, rarely on the ground, Guadalupe Island to British America. 
TRIBE IL-GRAMMITIDE^. 
II. GrYMNOGRAMME, Desvaux. Gold Fern. 
Fruit-dots oblong or linear, and like the veins either undivided or 
forked. Fronds pinnate, in our plants three to five angled ; lower pin- 
nae twice-parted, nearly as broad as long. Distinguished from Noth- 
olaena also by the fine lines of spore-cases that run from the margin to 
the midrib like veins, in fronds that are not too mature. 
A large genus, two species in the United States. The name, taken from the Greek, 
meaning naked spores, in allusion to the lack of indusium. 
6. Gr. triangularis, Kaulfuss. (The three cornei'ed G.) 
Fronds smooth or granular above in the typical form, densely 
covered beneath with a beautiful yellow or white powder: stalks dark- 
brown, polished. 
Shaded hillsides ; California to Vancouver Island ; common, Ecuador. 
7. Variety viscosa, Eaton. (The viscid \2x.') 
Frond viscid above. 
Southern California. 
8. Gr. MspMa, Mettenius. (The stiff-hairy G.) 
Frond covered with long, stiff hairs above, woolly and minutely 
scaly beneath: stalks grayish, minutely pubescent. ((?. podophylla.
