9« TILIACE^. 



3. T. althseoides. Lam. Siiffrutescent, veUety vrith 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-glotose, i-i-loai- 

 lar, glabrous : glochides hairy, equalling its diameter. — Calyx 24'" long, equalling the petals ; 

 achenium 2'" long, li'" broad (vfithout the glochides). — The leaves are much more velvety 

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

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

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



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

 sometimes glabrescent 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, i-locular, usually 4-sper- 

 mous, glabrous : glochides glabrous, equalling its diameter. — Jacq. Amer. Pict. t. 133 ; 

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

 foUa, 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, equalUug the petals; 

 achenium IJ"' 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 bilociJar fruit ; the spe- 

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

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

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

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

 Mexico ! to Venezuela I 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, S-5-locular, hoary-tomentose : glochides glabrous, half as long 

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

 branches subdichotomous ; calyx nearly 3'" long; achenium 1^'" diam. (without the glo- 

 chides), densely covered with hairs. — Hab. Jamaica !, Macf., Dist., AL, Wils., common ; 

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

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



6. T. hispida, Bich. 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. — Has. Jamaica!, 

 Bancr., March ; [Cuba; Panama!]. 



7. T. grossularifolia, Mch. 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 

 hairy, apiculate ; ^efe& oblong; stamens 20 (-10); stigma minute, subentu'e; achenium 

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

 —Rich. Cub. t. 21.— Leaves 2"-3" long, li"-2'' broad; calyx %«'-V<^ 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 l' 

 Guild.; [Cuba!]. *• & • , 



8. T. grandiflora, Yahl. 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 homomorphous; 

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

 petals obovate ; stamens 20-; stigma 6-fid; achenium (immature) globose, h-\om\w, glabrous':
