134 25. CIIEILANTHES, §§ EUCHEILANTHES. 



§§ Euoheilanthes. Imvolmres more or less confment, fronds not powdered 

 beneath, segments Iwrger and flatter than in Physapteris. Sp. 14-36. 



* Stipe scaly throughmit, or more or less tomentose. Sp. 14-24. 



14. C. micropteris, Swartz ; st. densely csespitose, wiry, erect, tomentose, 

 densely clothed with fibrillose light-brown scales at the base ; fr. 3-4 in. 1., 

 2-3 lin. br., simply pinnate ; pinnae \-\\ lin. br., ovate or roundish, crenate at 

 the base, deeply lobed, the outer surface convex, pubescent ; texture sub- 

 coriaceous ; rachis wiry, tomentose like the stipe ; sori roundish, 3 to 6 to each 

 pinna. — Hh. Sp. 2. p. 76. 



Hab, Tropical America, from Ecuador southward to Peru and the Argentine territory. 

 — The extreme forms of this and C. Matthewsii look very different ; but upon view of the 

 set of the Hookerian specimens, it seems doubtful whether they are really distinct. 



15. C. Matthewsii, Kunze ; rhizome stout, creeping, densely clothed with 

 linear-lanceolate dark-brown scales ; st. numerous, almost tufted, strong, erect, 

 wiry, densely pubescent ; fr. 4-12 in. 1., 1-2 in. br., linear-lanceolate, bi- or 

 tripinnatifid ; pinnae J-l in. 1., numerous, deltoid, much upcurled and incurved, 

 cut down to the rachis below into linear-oblong, crenate or pinnatifid pinnl, ; . 

 rachis stout, rigid, densely tomentose ; textv/re subcoriaceous ; sori numerous ; 

 invol. roundish, slightly confluent. — Hk. Sp. 2. p. 91. C. fasciculata, Qoldm. 



Hab. Andes of Bolivia and Peru. — C, prixinata, Kaulf , appears to be the oldest name, 

 but the plant is not at all pruinate. The pinnules have the margins so much incurved, 

 that it gives them the beaded habit of those of EugldcJienia. 



16. C. fragrans, Webb & Berth, (non Swartz) ; st. csespitose, wiry,- 1-3 in. 1., 

 densely clothed with reddish-brown linear scales ; fr. 2-3 in. 1., about 1 in. br., 

 ovate-acuminate, bi- or tripinnatffid ; pinnce opposite, ^-J in. 1., J-§ in. br., 

 deltoid, cut down to the rachis below into several sinuato-pinnatifid linear- 

 oblong lobes ; texture subcoriaceous ; rachis polished but slightly scaly, both 

 surfaces green and naked ; sori small, copious ; invol. light-brown, membranous, 

 toothed. — Hh. Sp. 2. p. 81. Polypodium fragrans, Linn. Mant. C. odora and 

 suaveolens, Swartz. C. maderensis, Lowe. 



Hab. South of France, Spain, Italy, Greece, Turkey, Canaries, Madeira, Algeria, 

 Syria, Afghanistan, and N. W. Himalayas at 5,000 ft. ; and I cannot point out any good 

 distinctive character for the South American 0. andina (Hk. Sp. 2. p. 115), gathered by 

 Mr. Maclean on the Peruvian Andes. Mettenius retains 0. maderensis as distinct from 

 the common S. European form. 



17. C. ardbica, Decaisne ; st. tufted, 1-3 in. 1., wiry, erect, dark chesnut- 

 brown, fibrillose and tomentose ; fr. 2-3 in. 1., 1-1-^ in. br., lanceolate-deltoid, bi- 

 er tripinnatifid ; pinnce opposite, the lowest ^-| in. 1., cut down to the rachis into 

 numerous linear-oblong segm., or slightly again branched at the base ; texture 

 subcoriaceous ; rachis chesnut-brown, fibrillose, upper surface naked, lower 

 slightly hairy ; sori copious. — Kunze, Linnoea, 23. p. 207. Mett. Oheil, p. 60. 



Hab. Abyssinia, Schimper, 1431. — 0. coriacea, Dec. (Hk. Sp. 2. p. 109), from Arabia, 

 appears to be either this or very closely allied. This oomea very near C. pulchella, but 

 is smaller in size, with a distinctly tomentose stipe and rachis. The ultimate segments 

 are lang|^ and narrower, ^nd the involucre more continuous than in 0. fragra/ns. 



18. C. vestita, Swartz (non Hook.J ; st. tufted, 2-4 in. 1., wiry, polished, 

 chesnut-brown, slightly tomentose, fibrillose ; fr. 4-8 in. 1., li-2 in. br., ovate- 

 lanceolate, tripinnatifid ; lower pinnce distant, opposite, ^-J in. 1., jt-j in. br. 

 lanceolate-deltoid, cut down to the rachis into several oblong pinnl. on each side 

 the largest of which are q^uite J in. 1., | in. br., cut down nearly or quite to the
