Plants Collected in Paraguay. 151 



marf^in may be called compound, crenate and serrate. Stipules of 

 3-branched hairs, the same kind of hairs running up the petiole to 

 some distance, and often dichotomously branching into 3 or 5 divi- 

 sions. Involucre slender, cylindrical, 15 mm. long, consisting appa- 

 rently of only one scale, the parts so completely coalescing that no 

 lines of junction can be seen, leaving only 5 small lobes at the apex 

 to mark their number. On this involucre are 5 rows of elongated 

 yellow glands. The plant seems to have a gre&t fancy for the num- 

 ber 5, there being often 5 branches to the stipular hairs, 5 lobes and 

 5 rows of glands on the involucre, 5 flowers in the head, 5 pappus 

 scales, 5 corolla lobes, and 5 stamens. 

 Flowering from October to April.

Senecio Bentliami, Griseb., Symb. Fl. Arg., 206. 



Caballero (411); Pilcomayo River (848). November-February. 



A very handsome flower. The heads large, rays crimson in color, 

 reflexed in full flower, tips of the corolla lobes reddish, and the pro- 

 jecting staminate column and stigma yellow, thus giving a wonder- 

 ful brilliancy of color to the flowers. It often climbs among trees 

 upon which it leans to the height of 3 m. or more.
