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

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

 of the calyx ; carpids glabrate, nearly equalling the connivent calyx.- — HC. in Mem. Genive, 

 1832, t. S. — M. triloba, Besf. — ^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 fi'uit, seems to 

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



34. OT. urens, Poit., Ledei. {a. 1805). Hispid; leaves ovate, bluntish, seiTate- 

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

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

 half exceeded by the linear erect points of the calyx. — ^M. ciHata, Pair. (1813), ex descript. 

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

 most of my specimens ; hut 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 t'yetals purplish- 

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

 Diss. t. 33. y. 3. — Involucre narrower, and with flie 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.). — Has. Jamaica!, Dist., Wils.; S. Vincent!, 

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

36. U. lobata, L. i,eaves 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 ; Desc. Fl. 4. t. 271.

 specimens of winch were compared by Sagot. TJ. Swartzii, Matf. {non DC). — Petals 6'"

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 suffiruticose plants. 



Sect. 1. PeM/EA. — Involucel l'0-iZ-leaved : leaves distinct from each other, filiform, and 

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

 Mowers glomerate ; flower-heads axillary, involncred. Leaves dotted.
