162 New Species of South American Plants 



scales in about 6 series, the outer successively shorter, lanceolate, 

 acuminate, thick, rigid and somewhat pungent. Rays densely 

 arranged in two series, exceedingly slender, their styles very 

 long-exserted and very deeply lobed. Receptacle foveolate, 

 finely short-hairy. Akenes narrow-pilose. Pappus copious and 

 fine, white, serrate. Disk-corollas very slender, slightly ex- 

 ceeding their pappus, the limb divided nearly to the base, the 

 lobes linear-oblanceolate. Anther bases acutish. 



"Machichoirisa, Bolivia, 3,500 feet, August 3, 1902" (R. S. 

 Williams, No. 1605.) 



Very near Lehmann's No. 1146, but the rays much more 

 numerous, the hairs of the receptacle different and the leaves 

 distinctly petioled. 



Moquinia tnacrocephala. 



Younger portions of stem pilose with spreading hairs, th^ 

 lower leaf-surfaces and inflorescence densely white-tomentel- 

 late. Branches elongated, ascending, rather stout, lightly 

 angled or terete, brown-purple. Petioles i cm. long, slender, 

 invested at the base with small, obliquely ovate, tomentose, 

 stipule-like appendages. Blades 6 to 10 cm. long, 2.5 to 3.5 

 cm. broad, oblanceolate, and bi-acuminate and acute, thick, 

 shining and finely reticulate-wrinkled above, the coarsely reti- 

 culate venation lightly prominent underneath, the margin en- 

 tire, thinly revolute. Corymb compound, more or less leafy- 

 bracted, the branches long-peduncled, densely flowered at the 

 summit, the heads short-peduncled, about 1.5 cm. long. In- 

 volucre two-thirds the length of the head, narrowly campanu- 

 late, the scales appressed, obtuse, in 5 or 6 series, the outer 

 broadly ovate and successively shorter, the inner oblong, more 

 or less purple toward the summit. Akene linear-oblanceolate, 

 5 mm. long, minutely pubescent. Pappus i cm. long, rather^ 

 coarse and sparse, tawny. Corolla-tube equaling the pappus, 

 slightly expanding above, the lance-linear recurved lobes equal- 

 ing the corolla lobes. Style-branches elongated, recurved, the 

 thickened summits pilose. 



Unduavi, North Yungas, Bolivia, 3,000 M., November, 

 1910. A shrub 3 or 4 M. high. (Buchtien, No. 3080.) 



Lycoseris oblongifolia. 



More or less white-floccose, except upper leaf-surfaces. 

 Branches elongated, simple, flexuous, reddish, angled and 

 finely sulcate, the internodes about 2 cm. long. Leaves 8 to 12 

 cm. long, 2 to 3 cm. broad, oblong, bi-acuminate, the summit 

 slenderly mucronate, the base tapering into a short petiole, 

 entire, thickish, above bright green, underneath white-floccose, 

 strongly 3-ribbed, the lateral pair starting above the base, all
