URENA. 



prominent barbed prickleB. We reniaidc. witk regret, that 

 the erroneous citation of Dillenius, 340 for 430, is copied 

 without corredlion from Linnxus, by Cavanilles, WiUde- 

 now, and even in Hort. Kew., which proves that thofe au- 

 thors did not confult the book cited, and therefore greatly 

 weakens our confidence in their authority or judgment, as to 

 critical fynonymy, throughout. 



2. \J . reticulata. Reticulated Urena. Cavan. Diif. 335. 



t. 183. f. 2. Willd. n. 2 Leaves with a folitary gland at 



the bafe beneath, reticulated ; the lower ones three-lobed ; 

 upper oblong-, fomewhat fiddle-ftiaped — Native of South 

 America. Defcribed by Cavanilles from Lamarck's her- 

 barium. Thejlem is (hrubby, a yard high, branched ; the 

 branches and footjlalh fomewhat downy. The lea-ves are 

 green above ; hoary with (hort down, and reticulated with 

 veins, beneath : the lower ones on longifh ftalks, hke the 

 foregoing, large, deeply three-lobed, their middle lobe 

 longeft : the reft narrow and undivided, varioufly contrafted, 

 on (hort ftalks. The midrib of all the leaves bears a folitary 

 gland. Flcjiers rather fmaller than in the former. 



3. U. tricufpis. Three-pointed Urena. Cavan. Diff. 

 334. t. 183. f. I. WiUd. n. 3. — Leaves vrith three pointed, 

 angular lobes, and a folitary gland at the bafe beneath. 

 Stem hairy. — Native of the iflesof Mauritius and Bourbon. 

 Thc7?fm is three feet, or more, in height, (lender, clothed 

 with copious upright hairs. Leaves large, ferrated, foft 

 and downy, on hairy ftalks. Flowers aggregate, at leaft in 

 the lower part of the plant, yellow. 



4. U. amertcana. Fig-leaved Urena. Linn. Suppl. 308. 

 Willd. n. 4. excluding Sloane's fynonym. (U. finuata; 

 Swartz. Obf. 263, but not of Linnaeus.) — Leaves three- 

 lobed, rounded and bluntilh, much longer than their foot- 

 ftalks ; entire and abrupt at the bafe, with a folitary gland 

 beneath. Stem nearly fmooth. Native of Surinam. We 

 have no fcruple in removing Sloane's fynonym to our follow- 

 ing fpecies. His plate by no means exprelTes the form of the 

 leaves of U. americana, which, in the original Linnaean fpeci- 

 men, have wide rounded Cnufes between the lobes. Their 

 under furface is very foft, and finely downy ; the upper more 

 harfh. Flo-wers fmall, moftly aggregate. Fruit muricated, 

 with (hort rigid prickles, rather large and broad. Very dif- 

 tinft from U. finuata, hereafter defcribed. 



5. M.ribefta. Currant-leaved Urena. ( Malva vel Alcea 

 fruticofa, ribefii foliis, feminibus afperis ; Sloane Jam. v. i. 

 37. t. II. f. 2.) — Leaves acutely tluce-lobed ; rounded or 

 heart-(haped at the bafe, with a folitai-y gland beneath. 

 Segments of the outer calyx fpatulate, bluntilh. — Native of 

 Surinam ; Herl. Linn, of Barbadoes ; Sloane. The Jlem is 

 much more hairy or downy than in the laft. Footjlalks 

 longer. Z-mtiw roughilh above, finely downy beneath, as in 

 that fpecies ; but their lobes are acute, not dilated nor 

 rounded, nor are the fmufes wide. The outer calyx has 

 greener, more leafy and dilated, very deep fegments. 

 Prickles of the Jruit much (horter than even the foregoing. 

 Sloane's figure cannot be miftaken. 



6. V.repanda. Wavy-leaved Urena. — Leaves wavy, fer- 

 rated, fcarcely lobed ; reticulated" beneath, with a fohtary 

 gland. Segments of the outer calyx awl-(haped. Fruit 

 fmooth. — Native of the Eaft Indies ; communicated by the 

 late Dr. Roxburgh. The Jlem is downy, with many (lender 

 axillary branches, hardly fo long as the leaves, on which the 

 flowers are chiefly fituated. Leaves broadly ovate, longer 

 than their footftalks, ferrated or (harply toothed, wavy, or 

 nightly lobed ; their upper fide even, rough with ftarry 

 hairs ; under ftrongly reticulated with copious veins, paler, 

 but fcarcely more foft or downy. Flotuers crimfon, axil- 

 lary, on (hort ftalk«, generally folitary. Outer calyn cloven 



but half way down, into five narrow acute fegments ; the 

 tube becoming ftrongly ribbed alter flowering, and contain- 

 ing the very fmall and unarmedyVa;/. 



7. \J. Jinuata. Cut-leaved Urena. Linn. Sp. PI. 974. 

 WiUd. n. 5. Ait. n. 2. Cavan. DifF. 336. t. 185. f. 2. 

 (" Uren ; Rheede Hort. Malab. v. 10. 3. t. 2." Alcea in- 

 dica frutefcens, foliis ad marginem exafperatis, bryonix 

 albae divifuris ; Pluk. Phyt. t. j. f. 3.) — Leaves five-lobed, 

 with broad, deep, rounded finufes ; lobes three-cleft : pale 



and hairy beneath, with three glands at the bafe Native of 



the Eaft and Weft Indies. This is known at firft fight by 

 the peculiarly wide rounded finufes of the leaves, which are 

 generally clofed, by the fides of the lobes touching or over- 

 lapping each other ; the middle lobe, and fometimes the two 

 adjoining ones, have three broad, (hallow, dilated and angu- 

 lar lobes : both fides are clothed with fimple or divided, not 

 much ftellated, hairs, and the under one, though pale, is not 

 hoary : its three principal ribs each bear a tumid open 

 gland at the bafe beneath. Flowers fmall, axillary, ftalked, 

 fohtary or in pairs. Segments of the outer calyx, according 

 to Cavanilles, narrow and awl-fhaped. 



S. U . heterophylla. Various-leaved Urena. (U. finuata; 

 Swartz Obf. 263 ? Malvinda foliis inferioribus multifidis, 

 fuperioribus incifis, (lore folitario ; Burm. Zeyl. 1 50. t. 69. 

 f. 2. Alcea indica frutefcens, foliis in lacinias varie dilTec- 

 tis ; Pluk. Phyt. t. 74. f. I.) — Leaves deeply five-lobed, 

 with wide finufes ; middle fegment deeply three-lobed : 

 upper leaves elongated and contracted at the bafe : all hoary 

 and downy beneath, with a folitary gland. — Native of the 

 Eaft, and perhaps Weft, Indies. To this fpecies, which 

 appears to us very diftinft from the laft, belongs the remark 

 under U.Jmuata, in Linn. Syft. Veg. of there being " one 

 glandular pore on the mid-rib beneath ;" which remark is 

 copied by Willdenow, though it direftly contradifts his own 

 obfervation in the next paragraph. If the number of glands 

 be invariably three in U. finuata, this is certainly diftinguifhed 

 by its folitary gland on the mid-rib ; but befides that cha- 

 rafter, the leaves are very differently (haped ; their finufes 

 lefs rounded, and their under fide more white and downy ; 

 to fay nothing of the Angularly contrafted upper leaves. 

 The fegments of the outer calyx are lanceolate. Corolla 

 purple. Prickles of the fruit elongated, doubly or triply 

 barbed. 



9. U. multifida. Jagged-leaved Urena. Cavan. Diff. 

 336. t. 184. f. 2. (Lappago laciniata ; Rumpli. Amboin. 

 V. 6. 59. t. 25. f. 2 ? Cavanilles.) — Leaves hairy, deeply and 

 acutely five-lobed, jagged, with a folitary gland beneath. 

 Stem much branched. Flowers fomewhat racemofe. — Na- 

 tive of the ifland of Mauritius. The whole plant is clothed 

 with (haggy down, apparently fimple. Leaves heart-{haped, 

 longer than their ftalks, their five lobes deeply cut or pinna- 

 tifid, acutely and unequally ferrated. Flotuers yellow, on 

 the fmaller or ultimate branches, on (hort ftalks ; the lower 

 ones axillary, the upper almoft leaflefs. The leaves are re- 

 prefented by Rumphius with far (lighter lobes than in the 

 figure of Cavanilles, and yet his fynonym, cited by Rei- 

 chard and Willdenow for lobata, and markedyTnwa.'a by Lin- 

 naeus, agrees better with the prefent fpecies. It may, how- 

 ever, belong to fome fpecies not yet known to fyftematic 

 botanifts. See our n. 11. 



10. U. procumbens. Procumbent Urena. Linn. Sp. 

 PI. 975. Willd. n. 7. Cavan. Diff. 337.—" Leaves haf- 

 tate, fomewhat heart-(kaped, undivided, ferrated. Stem 

 procumbent." — Gathered by 0(beck, on httle hills in 

 China. The Jlem is (hrubby, creeping, much branched. 

 Leaves the fiie of Origanum, not lobed, fmooth, ftiarply 

 ferrated. The fovjcrs are larger than the leaves. Linntus.
