Jamaica I, Bancr., IPils., Al.; S. Vincent!, Guild.; [Cuba! to Brazil!]. 325. C. Serra, TP. “ Muricateleaves 2-pinnatisect: secondary segments piunati- partite, sessile, serrate at the narrowly acuminate summit, tertiary falcate-oblong, bluntish, serrulate above, lower fertile from the base to or beyond the middle ; indusium circumscis- sile at the middle, at length shallow cup-shaped, entire at the margin : receptacle clavate, at length often 2-lobed.—Hoolc. Spec. t. 9. al.—C. arborea, Kz. (Disphenia, Pr.).—Trunk “ 30' high, or more ” {Pd.) ; ultimate segments 4'-6,,, long, V-lk' broad.—PIab.

Leaves 2-pinnatisect: secondary segments pinuatipar- tite, sessile, obtusely serrate at the short, contracted, blunt summit, tertiary oblong, blunt, crenate, or obtusely &e.TtsA&, fertile to about the middle: rhachis muricate; indusium cut to the base into irregular fragments: receptacle globose, entire.—Plum. Fit. t. 4.—C. Im- rayana, Hook. !: but his figure {Spec. t. 9.

Trunk “very slender” {Pd.) ; prickles of the petiole short, scattered on both sides ; primary segments ovate-oblong, ] l distant from each other, their petiole 1 long, secondary ovate-lauceolate, inferior 2', their partial petiole 2'-3' long, ultimate inferior 4'-5' long, 1broad.—Hab. Jamaica!, Pd., Fox Gap. 329. C. tenera, Hook. “ Unarmed;” leaves 2-pinnatisect: primary segments shortly petioled, their rhachis margined chiefly above by the narrowly decurrent secondary seg- ments, the latter subsessile, pinnatipartite, shortly acuminate, serrate at the point, tertiary oblong, blunt, serrulate at the summit, glabrous, fertile to about the middle; indusium at length irregularly shallow cup-sliaped, or dimidiate, subentire : receptacle minutely globose. —Alsophila, J. Sm.—Iu the same leaf the iudusia pass from the character of Cyathea into the dimidiate scale of such species as have hitherto beeu referred to Hemitelia: thus the description of C. multijlora, Sm. {Hemitelia, It. Br.) would agree, except iu the larger size of the segments. Secondary segments 2'' long, 8' broad (iu C. multijlora said to be 4 long, 1 broad), ultimate 4' long, 1-j' broad; sori distant. IIab. S. V iucent!, Ca/ey ; [Darien (/. 5m.)) ; C. multijlora, Sm.: Jamaica, [Guiana]. 47. ALSOPHILA, R. Br. Character of Cyathea, but indusium reduced to a palea, or none, rarely dimidiate-inferior. 330.
