EUPATORIUMS OF PERU. 59 



graduated, 2-ribbed and 3-nerved, the inner stramineous, acutish, tawny- 

 tomentellous toward the tip, the outer oblong, round-tipped, subher- 

 baceous, dorsally tawn y-tomentellous ; corollas slenderly tubular, 

 %\'ithout evident throat, glabrous, 5.5 mm. long; achenes 2.8 mm. long, 

 slender, tapering downward, fuscous, upwardly setulose toward the 

 summit; pappus-bristles about 30, dull-white, nearly smooth, almost 

 equalling the corolla. — Ann. Xaturh. Hofmus. Vienna, ix. 356 (1894). 

 E. sordcscens Bak. in Mart. Fl. Bras. vi. pt. 2, 306 (1876), in part, not 

 DC. — LoRETO: in mountains along the Mayo River, near Tarapoto 

 (incorrectly given by Klatt as Jarapoto), Spruce, no. 4804 (Gr.). With- 

 out EX.\CT locality: Lohb (Hofmus. Vienna, sk. and fragm. Gr.). 



This is one of several widely different plants included by Baker under 

 E. sordcscens DC, which in its typical form is a pretty well marked 

 species of Atlantic Brazil with much smaller (about 25-fiowered) heads, 

 linear and acute iuAolucral scales, and petioles (as stated by DeCandolle) 

 1.8-2 cm. long. The real E. sorclcscens seems to be well represented 

 by Riedel's no. 1348 (Gr.) determined by Schultz-Bipontinus. 



31. E. HELIANTHIFOLIUM HBK. Shrubby; branches Opposite, round, 

 dark-hispid; internodes 4-6 cm. long; leaves opposite, ovate, narrowed 

 from below the middle to an acute point, serrate except toward the 

 abruptly pointed base (teeth 1-1.7 mm. high, 4-6 mm. wide, mostly 

 acute), feather-veined, membranaceous, above scabrid, beneath hispid 

 with minute hairs and closely beset with orange-colored glands, 

 the largest leaves about 12 cm. long, 5 cm. wide; petiole subterete, 

 densely hispid, canaliculate above, 7-10 mm. long; inflorescence a 

 trifid very leafy flattish panicle; heads pedicellate, about 10-flowered, 

 8 mm. high; involucre campanulate-cylindric, the scales about 16, 

 imbricated, but not very strongly or regularly graduated, the inner 

 oblong-linear, smoothish, obtuse, the outer somewhat shorter, oblong, 

 acutish, hispidulous. — Nov. Gen. et Spec. iv. 127 (1820). — Piura: 

 near Ayavaca, Humboldt & Bonpland (Par., phot. Gr.). 



From the photograph in the Gray Herbarium tliis species appears 

 to resemble in habit the variable E. inulaefolium HBK. The leaves, 

 however, appear to be more regularly feather-veined, the petiole more 

 sharply defined, and the inflorescence more leafy. From the original 

 character it is to be inferred that the pubescence is more hispid and of 

 darker color. The t^,•pe-material is immature and until rediscovery the 

 status of this species must probably remain doubtful. 



32. E. VESTiTLTVi Poepp. Erect shrub with terete somewhat flexuous 

 leafy branches; pubescence on younger axes, as well as on the midrib 

 and chief \-eins of the lea\'es short, dense, rusty- velvety ; leaves petiolate,
