 pale green, ovate- triangular, acuminate, base deep-cordate, margin rather 

 coarsely serrate, 1J-2J in. long, J-1 J in. wide, closely bristly setose on 

 the nerves on both surfaces, otherwise glabrous; petiole 1-2 in. long, 

 bristly setose; stipules lanceolate, leflexed, with sparingly bristly mai- 

 gins, otherwise glabrous, 1^ lin. long. Racemes androgynous or some- 

 times 1-sexual, lateral, leaf-opposed, J-J in. long, on short, rather stiff, 

 puberulous and densely bristly peduncles \-\ in. long, with few rather 

 lax male flowers above and usually 2 basal female flowers ; pedicels all 

 solitary to and shorter than their bracts ; bracts all thinly membranous, 

 males 1 lin. long, narrow-lanceolate, reflexed, sparingly pubescent, 

 females lanceolate, 2 lin. long, of the upper female flower entire, of the 

 lower 1-toothed on each side near the base; bracteoles lanceolate, entire. 

 Male sepals 3, orbicular, obtuse, puberulous outside. Stamens 3 ; 

 filaments considerably longer than the anthers, incurved and sub- 

 connivent ; connective slightly thickened. Female calyx-segments 3, 

 1-seriate, ovate, membranous, accrescent but hardly indurated, 4 lin. 

 long, rhachis broadly ovate-oblong, pectinately 4-lobulate on each side, 

 sparingly hirsute externally, lateral lobules ascending, persistent, about 

 as long as the diameter of the rhachis, rather closely bristly setose. 

 Ovary nearly glabrous ; styles 3, glabrous, very long, connate for nearly 

 three-fourths their length in a rigid slender column. Capsule 3-coccous, 

 sparingly finely puberulous and with a few white bristles especially 

 along the middle, J in. across ; cocci bluntly angled along the back.

 and Otyisasu, 4000 ft., Dinter, 942 ! 



A distinct species with male flowers like tliose o( T. kirkiana, Miill. Arg., but 

 otherwise very different. 



38. T. furialis, Bojer, ffort. Maurit. 286. Stems long, slender, 

 twining, finely puberulous or nearly glabrous and sparingly armed with 

 stinging hairs. Leaves distinctly petioled, membranous, ovate or 

 ovate-oblong, acute or acuminate, base distinctly cordate, margin 

 shortly to distinctly serrate, 2-4 in. long, 1-2 J in. wide, sparingly to 

 distinctly bristly setose, especially on the nerves and especially beneath, 

 otherwise glabrous ; petiole £-2 J in. long; sparingly to closely bristly 

 setose with stinging hairs ; stipules lanceolate, 1-1 J lin. long, spreading 

 or somewhat reflexed with setose margins, otherwise glabrous. Racemes 

 lateral and terminal on the lateral branches, slender, rather dense, 

 J-| in. long, with a puberulous naked peduncle J-J in. long, with 

 many male flowers above and 1-3 basal female flowers ; pedicels in both 

 sexes solitary to and shorter than the bracts ; male bracts membranous, 

 narrow-lanceolate, sparingly hirsute, 1 lin. long, reflexed ; female bracts 

 like the male but slightly larger. Male sepals 3, wide-ovate, sparingly 

 hirsute externally. Stamens 3 ; filaments as long as the anthers.
