164 New Species of South American Plants 



the summit obtuse or barely acute. Peduncles 3 to 6 dm. high, 

 very slender and sparingly and slenderly long-branched, coarsely 

 angled, purple-red above, the heads few, slenderly and unequally 

 peduncled, 15 to 20 mm. long and broad, the turbinate involucre 

 equaling the pappus, its scales in 7 or 8 series, all elongated- 

 lanceolate except the outermost, acuminate, thick and rigid, 

 appressed, green above. Receptacle plane, foveolate, naked. 

 Purple rays in a single series, moderately exceeding the pappus, 

 hermaphrodite and fertile but the stamens apparently infer- 

 tile. Ray-akenes oblong, 3 mm. long, the copious whitish 

 pappus half the length of the corolla, serrate, the corolla 20 mm. 

 long, the tube 8 mm., the upper lip 4 mm. long, of two filiform 

 divisions, the lower lip 3 mm. broad, oblanceolate, truncate, 

 3-toothed, the teeth small, ovate, obtuse, the exserted anthers 

 3 or 4 mm. long, rigid, acuminate and acute, similar to those 

 of the disk-flowers, but apparently sterile. Mature disk-akenes 

 6 mm. long, linear-oblong, i mm. thick, reddish-brown, white- 

 pilose, their pappus about equaling the corolla, which is 12 

 mm. long, equally cylindrical, 1.5 mm. thick, rigid, the lobes 



1 mm. long, ovate, obtuse, little spreading, the anthers little 

 exserted, about 6 mm. long, the basal appendages filiform, the 

 filaments stout. Style stout, stigma 2-lobed. 



"In dry gravelly and clayey soil at Coroico, Yungas, Bolivia, 

 July 30, 1894, the flowers rose-colored." (M. Bang, No. 2365.) 



Very near 0. sagittatus, {" Seris sagittatus" Rusby) but 

 clearly distinct by its broadly winged petioles and different 

 ray and disk-florets. 



Jungia grossulariaefolia. 



Short-hairy and somewhat scabrous, the branchlets stout, 

 very ffexuous and rough-nodose, apparently ascending from 

 partially decumbent or declined stem?. Petioles slender, i or 



2 cm. long, the blades 1.5 to 3 cm. broad and not quite so long, 

 •sub-rotund, some of them slightly cordate, bearing on each side 



3 or 4 large ovate teeth, their summits varying from acutish to 

 rounded, some of them obscurely crenate-dentate ; thin, bright- 

 green, the venation slightly prominent above, strongly so be- 

 neath, where about 5 strong ribs radiate from the base, the 

 venation finely reticulate, the finer veins blackish-purple on the 

 lower surface. Peduncles terminal, elongated, very slender, 

 very flexuous, very openly and loosely branched, the ultimate 

 peduncles almost capillary, the bracts lance-linear, attenuate. 

 Involucre 8 mm. long, the scales linear-lanceolate, acuminate 

 and acute, the outer longer. Akenes numerous, 5 mm. long, 

 very slender, tapering upward. Pappus 7 mm. long, very 

 fine, copious, white. Disk-scales 6 mm. long, lanceolate, hya- 

 line. Corolla-tube a little shorter than the pappus, the lower
