POLYPODIACEAE 



16. NOTHOLAENA R. Br. Prodr. Fl. Nov. Holl. 1 : 145. 1810. 



Small rock-loving, mainly xerophilons ferns, with glandular, densely ceraceous. palea- 

 ceous, or variously hairy foliage. Fronds uniform, the blades 1-4-pinnate and variously lobed 

 or pinnatifid, linear to broadly deltoid or pentagonal. Sori usually submarginal, roundish or 

 oblong, borne at or near the tips of the unmodified veins (sometimes decurrent), more or 

 less confluent laterally. Proper indusia wanting, the margin revolute and partially covering 

 the sporangia in some species, flattish in others, the sporangia then somewhat concealed by 

 the hairy, scaly, or ceraceous covering. [Name Greek, meaning spurious cloak, in allusion 

 to the absence of a proper indusium.] 



About 60 species, some of them widely distributed. Besides the following, numerous other species occur 

 in the southwestern United States and in tropical America. Type species, Acrostichum marantae L. 



Blades densely tomentose beneath. 



Stipe and rachis sparsely hirsute; pinnae stalked, coarsely and densely hirsute-tomentose above. 



1. A'^. parryi. 

 Stipe and rachis at first densely tomentose; pinnae sessile, finely tomentulose above. 2. N. newberryi. 

 Blades glabrous or ceraceous beneath. 



Blades broadly deltoid-pentagonal, ceraceous beneath; segments close, mostly sessile or adnate; margins 



revolute. 3. A', calif ornica. 



Blades oblong-ovate to narrowly triangular, glabrous; segments distant, mostly short-stalked; margins plane. 



4. A. ionesii.

Rhizomes oblique or short-creeping, tufted, thick, densely 

 paleaceous ; scales tufted, subacicular, 4-6 mm. long, cinna- ; 

 momeous, mostly with a thick narrow brown stripe, entire. 

 Fronds numerous, clustered, erect, 6-18 cm. long ; stipes 3-8 cm.""i'^^ 

 long, slender, brown or purplish brown, hirsute; blades linear- '^^^ 

 oblong to ovate-oblong, acutish, 3-8 cm. long, 1-3 cm. broad, fe-.-, ■, ,, 

 3-pinnate; pinnae 5-9 pairs, mostly oblong-ovate, delicately UCf^l^ 

 stalked, involute with age, the lower ones subdeltoid, distant ; 

 segments small, close, roundish to ovate-oblong, crenate or 

 crenately incised, confluent, fragile, closely enveloped by the 

 woolly covering, buff-tomentose beneath, above coarsely 

 hirsute-tomentose, light grayish ; sporangia few, black, partly 

 visible with age; leaf tissue very delicately herbaceous, wholly 

 covered. 



Crevices of rocks, Sonoran Zones; desert region of southern Califor- 

 nia to south-central Arizona and southwestern Utah, ascending to 1740 



meters in the Panamint Mountains. 

 Utah. 





Type locality: near St. George,

Notholaena newberryi D. C. Eaton, Bull. Torrey Club 4: 12. 1873. 

 Rhizomes slender, creeping, branched, entangled, densely 

 appressed-paleaceous ; scales acicular, 2-3 mm. long, rigid, 

 blackish brown, glossy, entire. Fronds clustered, erect, 

 8-24 cm. long; stipes 4-14 cm. long. wiry, purplish brown, 

 glossy, at first closely tawny-tomentose; blades narrowly 

 oblong to oblong-lanceolate, acuminate, 4-13 cin. long. 1.5-5 

 cm. broad, 3-pinnate, finely and densely tawny-tomentose 

 beneath, delicately whitish-tomentulose above, the woolly 

 covering persistent throughout; pinnae about 10 pairs, 

 oblique, narrowly triangular to oblong-ovate, 

 tly inequilateral, sessile, the lower ones distant, sub-

■''■''^^equal, broader; segments minute, close, roundish-obovate, 

 entire, or the larger ones crenately lobed ; sporangia pro- 

 truding and mostly visible with age ; leaf tissue membrano- 

 herbaceous. 



Rock crevices, mainly in the Upper Sonoran Zone: lower hills 

 of the coast ranges, southern California, from Los Angeles to San 

 Bernardino, south to San Diego; also on San Clemente Island, and 

 on Guadalupe Island, Lower California. Type locality: San Diego.
