MALVACEAE. 81 



83. M. palmata, Mch. Usually hispid ; leaves roundish (lobed or entire) ; flower-heads 

 peduncled ; calyx 5-fid or deeply 5-fid : lobes ovate-lanceolate ; petals yellow, twice the length 

 of the calyx ; carpids glabrate, nearly equalling the connive?it calyx. — DC. in Mem. Geneve, 

 1832, t. 5. — M. triloba, Desf. — This species is usually confounded with the preceding, and 

 cannot be distinguished by the leaves ; the calyx however not terminated abruptly with an 

 elongated, linear, or setaceous point, but gradually tapering and equalling the fruit, seems to 

 present a specific character, though the habit be identical. — Hab. Trinidad!, Cr. ; [Cuba!]. 



34. M. urens, Poit., Ledeb. (a. 1805). Hispid; leaves ovate, bluntish, serrate- 

 toothed, entire ; flower-heads sessile ; calyx deeply 5-fid : lobes lanceolate or ovate-la uceo- 

 late ; petals . . ., twice the length of the calyx ; carpids villous, very convex on the back, 

 half exceeded by the linear erect points of the calyx. — M. ciliata, Poir. (1813), ex descript. 

 Rich. Cub. — Richard describes the petals as purple, and so they are in the dried state in 

 most of my specimens ; but Mr. Wilson sent others with petals which had dried yellow, yet 

 quite agreeing in all other characters. The species is easily recognized by the spreading, 

 dense carpid-down, which however sometimes disappears with age. Stem 4-6' high. — Hab. 

 Jamaica!, Pd., Wils., in waste grounds; [Cuba! to S. Thomas!]. 



35. M. radiata, L. Hispid with long, stinging hairs ; leaves mostly Z-fid to the 

 middle : middle lobe and uppermost leaves oblong, pointed (or ovate) ; flower-heads usually 

 peduncled (or with accessory sessile ones) ; calyx deeply 5-fid : lobes lanceolate ; petals purplish- 

 white, twice the length of the calyx ; carpids glabrous, half exceeded by the calyx. — Cav. 

 Diss. t. 33. /. 3. — Involucre narrower, and with the basilar, reticulated, white spot less deve- 

 loped than in the other species; stem higher, 6'-9' high, very hispid, and "admirably 

 adapted for use as a fibrous plant" (Wils.). — Hab. Jamaica!, Dist., Wils.; S. Vincent!, 

 Guild.; Trinidad!, Schach, Cr., common; [Panama!, Venezuela!, Guiana!]. 



9. URENA, L. 



Carpids 5, dry, glochidiate, at length separating from each other : style 10-fid. Calyx- 

 lobes alternate, with a 5-partite, persistent involucel. — Suffruticose or shrubby plants ; leaves 

 usually furnished beneath with 1-3 slit glands on the base of the nerves ; flowers subsoli- 

 tary, axillary. 



36- U. lobata, L. Leaves either trifid above the middle, or with obsolete lobes and 

 entire, glaucous-pubescent beneath : lobes ovate or oblong, minutely serrate : slit glands 

 usually solitary (sometimes 3) ; petals pink. — Cav. Diss. t. 185./. 1 j Desc. PI. 4. t. 271. 



Petals 6"'-8"' long, three times exceeding the calyx. 



a. americana, L. Involucel-segments exceeding more or less the calyx ; carpids pubes- 

 cent.— Car. Diss. t. 183./. 2, t. 184./. 1.— IT. reticulata, Cav., Macf. U. viminea, Cav. 

 U. Swartzii, Rich. Cub. {non DC). U. microcarpa, DC. 



&. Swartzii, DC. Involucel-segments equalling exactly the calyx ; caqrids tomentose. — 

 U. sinuata, Sw. Obs. [non L). U. americana, Sm. U. ribesia, Sm. 



Hab. Jamaica!, Dist., Al., March, common in dry hill-pastures; S. Kitts!, Antigua!, 

 Nichols., Dominica!, Imr. (a), S. Vincent!, Guild.; Trinidad!, Cr.; [Guiana!, Brazil!; 

 Western Africa, Mozambique!; East Indies !, China ! ; Pacific Islands]. 



37. \J. sinuata, L. Leaves b-Z-lobed beyond the middle, glaucous-pubescent beneath •. 

 lobes rhomboid, contracted at the base, irregularly senate : slit glands 3 ; involucel-segments 

 equalling the calyx; petals pink. — Cav. Diss. t. 185./. 2. — U. paradoxa, Kth. : original 

 specimeus of which were compared by Sagot. U. Swartzii, Macf. {non DC.).— Petals 6'" 

 long, three times exceeding the calyx ; carpids hirsute. — Hab. Jamaica !, Al., March, common 

 in moist pastures ; Caribbean Islands ; Trinidad!, Cr.; [Cuba I; Venezuela; East Indies!]. 



10. PAVONIA, Cav. 



Carpids 5, dry, at length separating from each other .- style 10(-8)-fid. Calyx surrounded 

 by an involucel of 5-15 either distinct or united leaves. — Shrubs or suffruticose plants. 



Sect. 1. Vem; s&K.-r-Involucel \0-\2-leaved : leaves distinct from each other, filiform, and 

 enlarged abruptly at the top to a minute limb. Carpids dehiscent along the dorsal line. — 

 Flowers glomerate : flower-heads axillary, involucred. Leaves dotted.
