306 ARALUCE^. 



trees, with simple, entire, leathery leaves ; umbels simple; pedicels jointed at the thickish 

 hose : involucre minuted 



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

 large disc, aud 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 Anonacete : such I do, however, not find in the still imma- 

 ture seed of H. pendula. 



1 . H. pendula, Sw. Leaves lanceolate-oblong or elliptical, glabrous ; peduncles much 

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

 turbinate ; petals equalling the stamens. — Sw. Ic. t. 9. — A large or low tree ; leaves vari- 

 able, 4"-3" long, usually long-petiolcd ; petals 1'" long. — Hab. Jamaica !, Wils., in the 

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



2. H. nutans, Sw. Leaves elliptical, glabrous ; peduncles nearly as long as the peti- 

 oles, stiff': exterior pedicels nodding; calyx-limb subeutire : tube hemispherical ; stamens 

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

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

 petals IV" long. — Hab. Jamaica!, Mac/., M'Nab, AL, on the peak of the Blue Mountains. 



2. SCIADOPHYLLUM, P. Br. 



Flowers polygamous. Petals 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)-pyrenous. — Glabrous, low trees; leaves leathery, simple or 

 digitate ; umbels or flower-heads arranged in corymbs or racemes ; iuvolucre minute. 



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

 petals ; Swaitz, though combining them with Iledera, recognized their affinity with Sciado- 

 phyllum Brownei, which is their true congener. 



3. S. Jacquini, Gr. Leaves simple, elliptical, repand-undulate, or obsoletely serrate, 

 reticulated-veiny : primary veins equal ; umbels in terminal, simple corymbs : peduncles 2- 

 1-bracteolate about the middle; calyx-limb 5 (-4-6) -dentate; petals aud styles 5 (4-6); 

 berry 6(-5)-celled, furrowed. — Jacq. II. Schcenbr. t. 51 : the furrows in the white berry 

 are neglected in this figure. — Aralia arborea, Jacq. Hedera, Sw.- — 20-12' high; leaves 6"- 

 4" (-1»") long : petiole of variable length; peduncles l"-2", pedicels 3"'-4"' long. — Hab. 

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



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

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

 racemes : peduncles naked, scaly-pubcrulous ; calyx-limb truncate, with minute, distant teeth ; 

 petals 4-5: styles 8-10; berry 8-10-celled, smooth. — Jacq. Amer. Pict. t. 91. 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!]. 



5. S. Brownei, Spreng. Leaves digitate : leaflets 10-6, oblong, gkbrate, 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 ; petals 5, cohering, calyptriform ; styles 5 ; berry 

 5-celled, deeply furrowed — Br. Jam. 1. 19./. 1. — Hedera Sciadophvllum, Sw. — Stem nearly 

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

 rounded or subcordate at the base; racemes usually 1' long: peduncles 2"'-3'" long. — Hab. 

 Jamaica!, Pd., Al., Wullschl., in mountain woods, S. Andrews, S. Ann9, Manchester. 



3. PANAX, L. 



Flowers polygamous. Petals 5, valvate. Stamens as many. Styles 2 (-4), diverging 

 above the epigynous disc. Fruit compressed, roundish-didymous : pyrense tardily distinet. 

 — Woody plants; leaves usually compound ; flowers umbellate. 



6. P. attenuatum, Sic. Arboreous, glabrous, unarmed ; leaves digitate .- leaflets 5-3
