 which is simply called "mautofu" or burweed.

 Triumfetta rhomboidea. Small burweed. 



Local names.— Dadangsi, Dadanse (Guam); Pegapega (Spanish). 

 A pubescent or glabrous weed with small yell<nv flowers growing in dense cymes. 

 Leaves ovate, rhomboid, or cordate, 3 to 7-nerved, apex acute or somewhat 3-lobed, 

 serrate, variable in amount and quality of pubescence; flowers mm. long; pedicels 

 short; flower-buds oblong, club-shaped, apiculate; sepals oblong, apiculate; jietals 

 oblong, (-iliate at the base; stamens 8 to 15; capsule the size of a small pea, whitish- 

 tomentose between the spines; spines hookeil, glal)rous or ciliated. The sjiecies of 

 this genus are so variable according to the various conditions of light and moisture 

 and nature of the soil, that it is possible forms of the same species may be mistaken 

 for distinct species. In making collections a series of jilants should be gotten grow- 

 ing in different situations. 



I have referred to this species the plant mentioned by Gaudichaud as Triumfetta 

 lappula, as that species is West Indian and is not further recorded from the Pacific. 



The plant yields a soft, glossy fiber, and like the allied sjiecies is mucilaginous, but 

 it is not utilized in Guam.

Trium^fetta tomentosa. Woolly burweed. 



Local names. — Masigsig lahe (?) (Guam). 

 A widely spread tropical weed. It is possible that Gaudichaud referred to this 

 species in giving in his list of Guam plants Corchorus tomentosus, which is a Japanese 

 species. T. tomentosa differs from other species of the genus in having the spines of 

 its fruit not hooked. It is an erect, branched, perennial herb, with softly hairy 

 stems, often found near cultivated ground, with numerous small yellow flowers in 

 clusters opposite the leaves. Leaves 7 to 12 cm. long, passing gradually into bracts 

 in upper part of stem, ovate or ovate-lanceolate, slightly cordate at the base, acute, 

 serrate, densely stellate-tomentose on both sides; petiole 1.2 to 5 cm. long; stipules 6 

 mm. long, setaceous; flowers on slender pedicels, clusters forming interrupted, spi- 

 cate, terminal panicles, buds linear-clavate; sepals 5, narrowly linear, apiculate, 

 denselj' stellate-haii'v; fruit globose, about 5 mm. in diameter, glabrous, covered with 

 numerous straight, sharp spines ecjualing its diameter, and bristly for lower half. 

 Flowers opening only in the afternoon. «
