    ilium L. P. subincisum, T7. (Alsophila martinicensis, Si eh. Mart. Crypt. Bras. t. 64), P. spec- tacle’ Kaulf.,- P. Karsteniauum, Kl.: forms without indusium, distinguished by variable cha- racter’s. Variable iu the down {e.g. the rhachis pilose or pubescent), the son close to the midrib or between it and the margin, confined to the lower anterior vemlet or several in each lobe, the ramification of the veins, and the division of the leaf: 1 etiole8 -12 .blade 8 10 long (Witts), the former woody ; lower tertiary segments 6 long, 2 b'-oador larger.—Hab. Jamaica!, Macf., Pel., Barter., At., Wits., rare, in moist woods at 3-4000 alt., e.g. Cold Spring Plantation, Fort Steward, Bluefield Mountains j [Cuba! to French islands!, Sieb. Mart 346; Venezuela! to Valdivia!]. 249. A. amplum, Metten. Leaf 2-pinnatisect with deeply pinnatipartite secondary segments : rhachis glandular-puberulous, paleaceous : tertiary segments oblong, blunt, ser- rate, inferior pinnatifid, adnate or shortly decurrent at the equal base; veinlets pinnate, simple or forked; indusium minute, cordate or suppressed.—SI. t. 57- /• 3 (Polypodium effusum, Sw., FI., non Synops.). P. Sloanei, Kze.: the characters, observed by Sir W. Hooker’ viz. the petiole not tubercled] and the narrow, silky palete, are confirmed by our spe- cimens ’but scarcely constant, and the indusium is often suppressed in both forms. P. lach- nopodi’um, J. Sm.—A. effusum, Gr.,is similar, but its secondary segments are twice as broad at the base. 2'-3' high, broad at the base ; inferior tertiary segments 4'-6 long, 2 broad.—Hab. Jamaica!, Pd., Wils., Al.; Dominica!, Imr., S. Vincent!, Guild.; Trinidad!, Sch.; [Cuba ! to French islands !; Mexico to New Granada]. 250. A. hirtum, Sw. Leaf 2-pinnatisect with pinnatipartite-2-pinnatipartite segments, glandular-puberulous: rhachis pubescent, paleaceous: ultimate segments ovate, pointed, entire, adnate and shortly decurrent at the equal base, 1-2-sorous: veinlets few, simple or forked’; indusium minute, reniform or suppressed.—Plum. Fil. t. 43. Kze. Farnlcr. t. 135 —a. nemorosum, W. Polypodium crystallinum, Kze— Slender, 6-12 high; ulti- mate segments long, broad.—Hab. Jamaica!, Pd., March, on moist, shady rocks; [Cuba!; Guatemala; trop. Africa]. *** Leaves pinnalisect with pinnatipartite segments: veins free, lowest veinlets distant at the sinus (Conf. Polypodium caudatum, Kaulf.; P. decussatum, L.; P. Hewurdii, Gr.). 251. A. sanctum, Metten. Slender; leaf pinnatisect or 2-pinnatisect with respect to the 2 lowest, larger secondary segments, puberulous beneath at the ribs only : primary seg- ments pinnatipartite, lowest much decrescent, secondary oblong-lanceolate, bluntish, decur- rent, subentire: veinlets simple or forked : rhachis puberulous; sori sub equidistant from the midrib and margin, small: indusium “ minute, reniform, ciliate ” or suppressed.—SI. t. 49. /. 2.—Polypodium, Sw.—6-12 high; secondary segments 2' long, lowest oftcu as large, approximate to the rhachis.—IIab. Jamaica!, Macf, Bancr., Pd., AL, on rocks; [Cuba!]. 252. A. conterminum, W. Leaf pinnatisect, puberulous or glandular beneath, or gla- brcscent: primary segments pinnatipartite or pinnatifid, acuminate, lowest much decrescent, secondary oblong, obliquely bluntish, subentire, lowest usually larger: veinlets simple : rhachis puberulous ; sori nearer to the margin than to the midrib : indusium small, reni- form, ciliate.—Plum. Fil. t. 47.—A. polyphylluin, Kaulf. A. sanctoides, Fee. Polypo- dium coucinnum, Sieb.—l'-2' high ; secondary segments 2'-]' long, lowest often twice as large, approximate to the rhachis, but not separated from the rest as in the preceding.— Hab. Jamaica! Wils., Al., Blue Mountains to 7000' alt.; [Cuba! to French islands; Mexico ! to Brazil!]. 253. A. oligocarpum, Kth. Leaf pinnatisect, puberulous: primary segments pin- natipartite, subsessilc, lowest decrescent, secondary oblong or oblong-linear, blunt, entire, nearly horizontal, lowest not enlarged: veinlets simple: rhachis hoary-puberulous ; indu- sium small, reniform, ciliate or suppressed.—Itadd. Fil. Bras. t. 34.—Polypodium pubes- cens, Badd.—1 p-3' high ; secondary segments 3'-2' long. a. Special segments oblong-linear, broad; sori near the margin. /3. Kaufussii, Lk. Special segments oblong, Hff-V broad ; sori more distant from the midrib than from the margin.—Link’s Fern is known to me from cultivated specimens of
