E. lanicaule. Stems 1 to 3 m. high, terete, striate, covered at least 

 when youug with shaggy tawny wool : leaves opposite, thickish, short- 

 petioled, oblong, acuminate, sharply serrate, narrowed to a crisped base, 

 appressed-villous above especially upon the veins, soft-pubescent upon the 

 pinnate prominulous veins beneath, concolorous, slightly reticulate, 1.3 to 

 1.6 dm. long, 2 to 5 cm. broad; petioles lanate, 5 mm. long; inflores- 

 cence somewhat rigid, rather dense ; lower branches widely spreading, 

 thickish ; bracts lance-linear, nearly equalling the heads ; involucre sub- 

 turbinate; the scales pluriseriate, elliptical, regularly imbricated, at length 

 campanulately spreading, finely striate, ciliolate : flowers 1.2 cm, long: 

 corolla 7 mm, long, cylindrical with little enlargement at the throat : 

 pappus slightly tawny, of the same length : achenes columnar, puberulent 

 on the angles. — Collected by Dr. Sereno Watson in the " eastern por- 

 tions of Vera Paz and Chiquimula," 188-5, nos. 74 a, 123. Types in herb. 

 Gray. Nearly allied to the W. Indian E. placheoides, Griseb., but dif- 

 fering in its larger heads, broad smoothish obtuse involucral scales, etc. 



E. Loesenerii. Shrub, 2 to 3 m, high ; branches stout, terete, 

 opposite, curved-ascending, covered with a smooth gray cortex with 

 longitudinal rifts, the lenticels not prominent ; branchlets stoutish, 

 elongated, covered with a fine ochraceous tomentum (sometimes reduced 

 to a mere pulverulence) : leaves opposite, petiolate, broadly ovate or 

 oval, shallowly cordate, rounded or very obtuse with slight mucro at the 

 apex, obsoletely serrate or entire, 5 to 6 cm. long, 4 to 5 cm. broad, 

 subpalmately veined, pale green and pulverulent above, tomentulose and 

 ochraceous beneath ; petioles 2 to 3.5 cm. long, strongly channelled above, 

 subconnate at the base : heads numerous, about 20-flowered, in terminal 

 round-topped compound corymbs (9 to 12 cm. broad) ; pedicels 7 to 9 mm. 

 long; involucres tomentulose, 3 mm. long, campanulate, the scales sub- 

 equal, obtuse or barely acute, ciliate, ochraceous or purplish, scarcely at 

 all herbaceous : corolla white or pale purple, 4 mm. long, glabrous, 

 resinous-punctate on the teeth : pappus-bristles about 20, white, unequal ; 

 angles of the achene upwardly hispid, — Collected in Oaxaca by C. G. 

 Pringle on calcareous hills, Las Sedas, altitude 1,800 m., 30 October, 1894, 

 no, 6022, type (in herb. Gray), This plant was unfortunately determined 

 as E. sordidum, Less., from the not altogether satisfactory description 

 of that species. A comparison by Mr. J. M. Greenman of Mr. Pringle's 

 plant with authoritative material of E. sordidum now shows that the latter 

 is quite distinct, being in fact of the Hebecliniiim group. E. Loesenerii 

 has also been collected by E. W. Nelson along the Cuicatlan road, Valley 

 of Oaxaca, altitude 2,100 to 2,400 in., 3 October, 1894, no. 1549; by
