ribs, scarcely 3.5 mm. long; pappus-bristles about 20, whitish.— 

 Hieron. in Engl. Bot. Jahrb. xl. 383 (1908). — Cajamarca: near

This species, said to be near the Colombian E. sotarense Hieron., 

 has not been seen by the writer and the above description is condensed 

 from the original of Prof. Hieronymus. The species from character 

 appears clearly distinct from other Peruvian Eupatoriums of its 

 affinity by its small broadly ovate and nearly sessile leaves. 



68. E. VALLI^xoLA DC. Shrubby, erect or nearly so, 5 dm. high; 

 stems (when young) and branches spreading-villous, the hairs jointed; 

 internodes 2-3 (-9) cm. long; leaves opposite, often proliferous in 

 the axils, deltoid-ovate, acute, subtruncate to shallowly and openly 

 cordate (shortly acuminate at the attachment), 2-3.5 cm. long and 

 wide, 3-nerved from the very base, coarsely and often somewhat 

 doubly crenate-dentate, above sparingly pubescent, beneath loosely 

 villous especially on the nerves and veins (the hairs slender, fiexuous, 

 jointed); petiole 1.4-2.5 cm. long; corymbs terminal, fastigiately 

 branched, rounded, few -many -headed ; pedicels 6-9 mm. long; 

 heads 20-25-flowered, 8-10 mm. high; involucre campanulate, the 

 scales subequal, linear, acute, pubescent, mostly 2-ribbed; corollas 

 white, 4.5 mm. long, hispid on the limb, with slender proper tube and 

 moderately enlarged throat; achenes (immature) 1.6 mm. long, 

 slightly contracted at the summit and tapering to the base, hispidu- 

 lous on the angles; pappus-bristles very few, often about 10, delicate, 

 white. — Prod. v. 168 (1836). — Lima: mountains of Barranco near 

 Lima, on calcareous rock, alt. 300-600 m., 23 Oct. 1902, Weberbauer, 

 no. 1650 (Berl., fragm. Gr.). Peru without exact locality: 

 Haenke (DC, phot. Gr.). 



Var. a. typicum. Hairs of the stem, petioles, pedicels, and some- 

 times on the lower surface of the leaves long, slender, spreading, more 

 or less conspicuously jointed. — Lit. and exsicc, as above. 



Var. |S. BREVIPILUM Robinson (p. 39). Puberulent to tomentellous, 

 the hairs mostly short, neither gland-tipped nor conspicuously jointed; 

 otherwise closely like var. a. — Lima: on the Lima and Oroya Rail- 

 road, between Matucana and Tambo de Viso, on rocks, alt. 2370-2650
