96 TILIACEiE. 



3. T. althseoides, Lam. Snffrutescent, velvety with stellate down ; leaves roundish or 

 lobed, unequally toothed, upper ones lanceolate : lower teeth homomorphous (sometimes 

 glandular at the top) ; flowers racemose : pedicels equalling the fruit ; sepals hairy, apiculate ; 

 petals oblong ; stamens 10 ; stigma obsoletely toothed ; achenium ovoid-globose, S—i-locu- 

 lar, glabrous : glochides hairy, equalling its diameter. — Calyx 2,%'" loug, equalling the petals ; 

 achenium 2'" long, 1^"' broad (without the glochides). — The leaves are much more velvety 

 than in T. semitriloba, which it approaches however perhaps too nearly, the chief difference 

 consisting in the glochides covered with retrorsely bent hairs. — Hab. Antigua !, Nichols. ; 

 Dominica !, Imr. ; [Bermudas !, Cuba !; Guiana !, Brazil as far south as S. Katherine !]. 



4. T. semitriloba, L. Suffrutescent, pubescent with stellate down, rarely velvety, 

 sometimes glabresceut on the upper side of the leaves ; leaves roundish, 3(-5)-lobed or sub- 

 entire, unequally toothed, upper ones lanceolate : lowest teeth homomorphous ; flowers in- 

 terruptedly racemose : pedicels equalling the fruit ; sepals hairy, apiculate ; petals spathulate ; 

 stamens 15 ; stigma obsoletely toothed ; achenium ovoid-globose, 2-locular, usually 4-sper- 

 mous, glabrous .• glochides glabrous, equalling its diameter. — Jacq. Atner. Pict. t. 133 ; 

 B4fc. Fl. 2. t. 102.— T. heterophylla, Lam. T. havanensis, Kth. T. ovata, DC. T. ulmi- 

 folia, Desv. T. diversiloba, Prl. T. angulata, Lam., partim, ex W. Am. et specim. Wallich. 

 T. rhomboidea, Auct. {non Jacq.). — Stem 4-6' high; calyx 3'" long, equalling the petals; 

 achenium 1£'" long, 1'" broad (without the glochides). — This is the most common, and con- 

 sequently the most variable, species of the genus, not to be distinguished from T. rhomboidea, 

 Jacq., by the leaves, but sufficiently so by the glabrous and usually bilocular fruit ; the spe- 

 cific value of the characters, derived from the number of the stamens and the fruit-cells, 

 appears donbtful in this genus, but the shape of the ripe fruit and the glochides afford 

 useful marks of distinction. — Hab. Jamaica!, List., Al., March, Wils., a common weed; S. 

 Vincent !, Guild. ; Trinidad !, Sieb. ; [all tropical countries of the globe ; e. g. Cuba 1 and 

 Mexico ! to Venezuela ! and Guayaquil ! ; tropical Africa ; East Indies !]. 



5. T. rhomboidea, Jacq. Shrubby ; branches scabrous with small, stellate bristles ; 

 leaves roundish, unequally toothed (usually angular and pointed), glabrescent above, pubescent 

 beneath, upper ones oblong : lowest teeth homomorphous; flower- fascicles distant: pedicels 

 equalling the fruit ; sepals hairy, shortly apiculate ; petals spathulate ; stamens 15 ; stigma 

 3-5-fid; achenium globose, Z-h-locular, hoary -tomentose -. glochides glabrous, half as long 

 as its diameter. — Jacq. Amer. Pict. t. 134. — T. rhombeifolia, Sw. — A shrub, 3'-4' high: 

 branches subdichotomous ; calyx nearly 3'" long; achenium IV" diam. (without the glo- 

 chides), densely covered with hairs. — Hab. Jamaica !, Mac/., Dist., Al., Wils., common ; 

 S. Vincent!, Guild.; [all tropical countries of the globe, e.g. Martinique!, Guayaquil!, 

 Brazil ! ; Senegambia !, Niger !, East Indies !]. 



6. T. hispida, Rich. Suffrutescent, hairy with simple hairs and short stellate down; 

 leaves ovate or ovate-roundish, unequally toothed, pubescent -. down of the under side stel- 

 late : lowest serratures homomorphous ; flower-fascicles somewhat distant : pedicels equalling 

 the flower ; sepals densely covered with a whitish villous down, long-apiculate ; petals ob- 

 long; stamens 20-15 ; stigma minute, subentire; achenium (immature) globose, pubescent : 

 glochides equalling its diameter. — Leaves nearly 1" long; calyx 3'" long. — Hab. Jamaica!, 

 Bancr., Mc~"h ; [Cuba ; Panama !] . 



7. T. grossularifolia, Rich. Suffrutescent, hairy with scattered, mostly simple hairs; 

 leaves ovate, entire or shortly 3-lobed, unequally serrate, upper ones oblong-lanceolate : lowest 

 serratures homomorphous; flower-fascicles distant: pedicels equalling the flower; sepals 



&S hairy, apiculate; petals oblong; stamens 20 (-10) ; stigma minute, subentire; achenium 



s (immature) ovoid-globose, 2-3-locular, glabrous : glochides glabrous, equalling its diameter. 



— Rich. Cub. t. 21.— Leaves 2"-3" long, *li"-2" broad; calyx 2"'-3'" long, equalling the 



petals. — The simple soft hairs of the stem and of the leaves, which are green on both sides, 



''afford characters to distinguish this species from all the preceding ones. — Hab. S. Vincent !, 



Guild.; [Cuba!]. 



8. T. grandiflora, Vahl. Suffrutescent or shrubby : branches villous with flexuose 

 hairs ; leaves broadly ovate, pointed, unequally crenate-toothed, hairy with scattered, mostly 

 simple hairs, or glabrescent, upper ones lanceolate : lowest serratures hoinonioq)hous ; 

 flower-fascicles distant : pedicels much longer than the fruit ; sepals glabrous, apiculate ; 

 petals obovate ; stamens 20; stigma 5-fid; achenium (immature) globose, 5-locvAax, glabrous :
