134 Plants Collected in Paraguay. 



The Yeriionias are very numerous in Paraguay, all of them 

 bearing heads of showy, purple flowers. I collected 9 species, only 

 a small part of the number occurring in the country. Perhaps the 

 most striking of them is V. glahrata (nos. 165, 590), with many 

 sessile heads 2 cm. in diameter, growing by fence rows and road- 

 sides in the vicinity of Asuncion. 



Another with ample leaves, rugose above and velvety hairy 

 beneath, numerous crowded flower-heads, and strong stems over 3 m. 

 in height, V. Tweediana (nos. IH, 653), abounded in waste grounds 

 around Asuncion. 



V. incana (no. 2t5) and V. graminifolia (no. 1509), both with 

 long narrow, linear leaves, the panicles of flowers on long naked 

 peduncles, are exceedingly graceful and ornamental species. 



V. Chamaedrys (nos. 339, 495) has a close, thyrsus-like panicle 

 of bright purple flowers. Leaves small, black or olive-green and 

 shining on the upper surface, and white woolly beneath. Stem 

 shrubbyish, l-H m. in height. 



Elepliantopus angustifolius, Sw., Prod., 115. 



Asuncion (162 a); Luque(313); Pilcomayo River (1510). 



Elepliantopus tonientosiis, L., Sp. PL, 814. 

 E. scaber, v. tomentosus, Schultz Bip., Linnsea, xx, 516. 



Asuncion (258). December. 



The two species of Elephantopus here noted are very difi'erent. 

 E. angustifolias has its flowers in terminal wand-like spikes, some- 

 times 3J dm. in length, the leaves oblanceolate, 1^-3 dm. long, the 

 glomerules subtended by a single small ovate bract. E. tomentosus 

 has its flowers in large terminal panicled corymbs, the leaves obo- 

 vate, 10-13 cm. long, the glomerules much smaller, subtended by 3 

 large foliaceous bracts. Both occur in old fields and open grounds, 

 the former very common in the vicinity of Asuncion and on the 

 Pilcomayo River. 



Adenostemma triangulare, D.C., Prod., v, 113. 



Trinidad (270) ; Pilcomayo River (1003). December-April. 

 = Balansa 865. 



Noticeable for its lowest leaves, which are broad hastate-deltoid, 

 sometimes 15 cm. long and as broad, and its corymbs of heads, 

 which appear to be nearly all styles and stigmas, having 2 or 3 

 rows of small, appressed scales, numerous green tubular corollas.
