    gramme, but has the habit of a common Aspidium.—3'-4' high; secondary segments long, liw broad.—Hab. Jamaica!, Hartiomountains of Port lloyal, West- moreland. ** Leaf pinnatisect with pinnatifid or serrate segments: lower veinlets approaching, contiguous, or anastomosing at or below the sinus, the other free, excurrent. 283. P. tetragonum, L. Leaf pinnatisect: segments lanceolate, pimiatifid to one- half-one-third, shortly petiolulate, lowest little or not decrescent: lobes oblong or ovate, blunt or bluntish, entire : veinlets simple, lowest pair anastomosing below the sinus, sending a vein into the sinus, following pair contiguous at the sinus: rhachis 4-gonal; sold serial: series extending to the lowest veinlets.—Variable, distinguished from similar forms of Aspidium rnolle, Sw., by petiolulated segments, and from A. abbreviation, Schrad. (non Hook.), perhaps not sufficiently by the anastomosis of the veinlets.—2'-5' high; segments 9-3 long, 12'-6' broad. a. Glabrescent (down simple) : segments 3— 6 long, pinnatifid to about the middle : lobes spreading: veinlets 6-10-jugal.—SI. t. 48. f. 2. Schk. Crypt, t. 18. b. fi. Plumieri, J. Sm. Puberulous with stellate down ; segments 6-9 long, pinnatifid to one-third : lobes falcate-blunt: veinlets 10-12-jugal,—Plum. Fil. t. 21. Hab. Jamaica!, Macfi; Dominica!, Imr., S. Vincent!, Guild.; [Cuba! and Mexico ! to Brazil and Peru!]. 284. P. megalodus, Schk. Stout; leaf pinnatisect, somewhat rigid, stellate-puberu- lous : segments oblong-lanceolate, coarsely serrate to one-fourth, petiolulate, lowest as large : serratures falcate, broadly ovate or oblong, bluntish or blunt, entire : veinlets simple, several lower pairs anastomosing below the sinus, forming a vein that runs into the sinus : rhachis puberulous, 4-gonal; sori serial: series extending often to the lowest veinlets.— Schk. Crypt, t. 19. b.—4-6' high ; segments 12-8 long, 11 broad: serratures 4'— 2' broad : veinlets 8-15-jugal.—Hab. Trinidad 1, Cr.; [Cuba !, Wr. 1010, to French islands !; Venezuela!]. 285. P. crenatum, Sic. Leaf pinnatisect, slightly hispidulous : segments oblong- lanceolate, crenate-serrate, subsessi/e: serratures truncate-appressed : veinlets simple, about 10-jugal, free and anastomosing without order : rhachis obtusely sub-4-gonal; sori distant, chiefly on the lower veinlets.—Plum. Fil. t. 111.—P. meniscioides, Liebm.—2'-3high; segments 4-8-jugal, longer 6 long, 1) broad.—Hab. Jamaica!, Wils., March; S. Vin- cent !, Guild.; Trinidad !, Loclch.; [Cuba! and Mexico ! to Venezuela! and Guiana !]. 286. P. flavopunctatum, Kaulf. Leaf pinnatisect, glabrescent, pellucid-dotted with yellowish points: segments oblong-linear, acuminate, coarsely cuneate-serrate, sessile at the oblique, upward produced base, shortly decurrent, lower largest: veinlets distant, 3-6-jugal, free, lowest second or third pair approaching at the sinus: rhachis pa- leaceous, obtusely 4-gonal below ; sori distant, chiefly on the lower veinlets.—Plum. Fil. t. 38.—Aspidium rotuudatum, W.—3-6' high : lower segments 6-10 long, 8'-12' broad. —Hab. Jamaica (Ilook.)-, Dominica!, Imr., S. Vincent!, Guild.; [French islands!; Mexico to Guiana! and Peru]. 287- P- obliteratum, Sw. ! Leaf pinnatisect, glabrous : segments lanceolate, serrate, or chiefly the uppermost pinnatifid-serrate, tapering at both subentirc ends, lower peliolu- late, as large, superior adnate-decurrent: veinlets simple, 6-10-jugal, lower anastomosing and forming a vein that runs into the sinus : rhachis puberulous, sub-3-gonal; sori approxi- mate to the middle, serial : series extending to the lower veinlets.—Approaching Aspidium Imrayanum, Hook., but segments uot upward produced at the base, and with a long spe- cial vein below the sinus, often unconnected with the appendage of the lowest anastomosis. —3-4' high; segments 6-10-jugal, 6-8 long, 1 broad.—IIab. Jamaica!, Sw., iu moun- tain-woods. *** Veins costate. 288. P. blecbnoides, Sw. Leaf pinnatisect : segments lanceolate, entire below the serrate, narrowly acuminate apex .- veins costate, approximate, simple or 2-partite, no veinlets; sori dorsal toward the base of the veins or scattered.—Hook. Gen. t. 42, B. Hook. Grev.Ic.t. 232. Alsophila, Hook. P. rosscatum, IF. (Amphidcsmium, Schott). P.
