306 ARALIACE^. 



trees, leith simple, entire, leathery leaves ; umbels simple ; T^edieeis jointed at the thicHsh 

 lose : involucre mimtte. 



I exclude those tropical species wliich have distinct styles, the calyx not produced, and a 

 large disc, and 1 refer these to Sciadophyllum.- — In the common Ivy the cylindrical embryo 

 is about half as long as the fleshy, ruminate albumen, the laminar inner projections of the 

 testa being analogous to those of Anonacece: such I do, however, not find in the stUI imma- 

 ture seed of jff. ^oeK^^Kfe. 



1. EI. pendula, Sio. Leaves lanceolate-oblong or elliptical, glabrous ; pedmneUsmnch 

 longer than the petioles, often eiceeding the leaves, pendulous'; calyx-limb subentire: tube 

 turhinate ; petals egualling the stamens. — Sw. Ic. t. 9. — A large or low tfee ; leaves vari- 

 able, 4"-S'' long, usually long-petioled ; petals 1'" long. — Has. Jamaica !, Wils., in the 

 mountains, rare at 3000' alt.; e.g. S. John Crow Hill. 



3. H. nuta,ns, £^. Leaves eWi^ica!^, ^shrisYa ; peduncles nearlg as Ktig as the peti- 

 oles, stiif: exterior pedicels nodding; calyx-limb'subentire : tube hemispherical ; stamens 

 exserted, half as long again as the petals. — A large forest tree {Al.), or dwarfish (jSw.), not 

 to be distinguished from the preceding by its foliage^ but calyx twice as broad (2"'-3"') and 

 petals li'" long. — Hab. JaiUaica !, Macf., M'Nal>, Al., on the peak of the Blue Mountains. 



2. SCIADOPHTLLUM, P. Br. 



Flowers polygamous. Fgtals 5 (4-6), valvate or coherent. Stamens as many. Styles 

 in 9 5-10 (4-12), diverging above the epigynous disc, in $ rudimentary and combined. 

 Berry globose, 5-10 (or 4-12)-pyrenons. — Glabrous, low trees ; leaves leathery, simple or 

 digitate ; umbels or flovter-heads arranged in eorymbs or racemes ; involucre minute. 



Jacquin referred two simple-leaved species to Aralia, which is distinguished by imbricated 

 petals ; Swartz, though combining them wi&i.- Hedera, recognized their affinity with Sciado' 

 phyllum Brovmei, wliich is their true congener. 



3. S. Jacquini, 6r. Leaves simple, elliptical, repaud-undulate, or obsolefely serrate, 

 reticiilated-veiny ; primary veins equal •" umbels in terminal, simple Corymbs ; ^edaiicl^s 2- 

 1-bracteolate about the middle ; calyx-limb 5(-4-6)-dentate ; pttals and styles 5 (4-6) j 

 berry 6(-5)-celled, farrowed. — -Jacq. R. Schcenbr. t.h\: the'rarrows in the white berry 

 are neglected in this figure. — Aralia arborea, Jac^. Hedera, Sw. — 20'-13' high ; leaves 6"- 

 4" (-li") long : petiole of variable length; peduncles l"-2", pedicels 3"'-4"' long. — Hab. 

 Jamaica 1, all coll., common in the lower mountains ; [Cuba !, Portorico 1]. 



4. S. capitatum, Gr. Leaves simple, ovate, elliptical}, or elliptical-oblong, quite entire, 

 long-petioled, veiny : basilar veiiis longer; flower-heads in compound (or simple), terminal 

 racemes : peduncles naked, scaly-puberulous ; calyx-limb truncate, wMh minute, distant teeth ; 

 petals 4-5: styles 8-10; berry 8-10-celled, smooth. — Jacq. Amer. Fict.t.'il. Sm. Ic. 

 Pict. t. 4. — ^Aralia, Jacq. Hedera, Sm. H. multiflora, DC. — 10'-12' high ; leaves very 

 variable, 4"-6" long ; peduncles 3"'-4"' long : flowers sessile; berry brown.— Hab. Ja- 

 maica !, all coll., common in woods ; Antigua !, Wullschl., Dominica !, Imr. ; [Martinique !, 

 Sieb. Mart. 94 ; Venezuela !, New Granada !, Brazil I] , 



5. S. 'Brovmei, Spreng. Leaves digitate : leaflets 10-6, oblong, glahrate, quite entire, 

 long-petiolulated :" sheath of the long petiole ' produced into an axillary ligule ; umbels in 

 elongated, nodding, puberulous, terminal and axillary racemes .- pedicels as long as the 

 naked peduncles ; calyx-limb subentire ; p^als 5, cohering, calyptriform ; styles 5 ; berry 

 S-celled, deeply furrowed.— Sc. Jam. 1. 19./. 1. — Hedera Sciadopbyllum, Sw. — Stem nearly 

 simple, 8'-12' high ; petioles 15"-5", petiolules 3"-l", leaflets 10f'-4" long, the latter 

 rounded or subcordate at the base; racemes usually 1' long : peduncles S"'-3"' long.^-^HAB.

 above the epigynous disc. Fruit compressed, roundish-didymous ; pyrense tardily distinct. 

 — Woody plants ; leaves tumally compound; flowers umbellate. 



6. P. atteuuatum, Sw. Arboreous, glabrous, unarmed ; leaves digitate .■ leaflets 5-3
