BK. lanicaule. Stems 1 to 3 m. high, terete, striate, covered at least 
when young 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 em. 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,” 1885, nos. 74a, 123. Types in herb. 
Gray. Nearly allied to the W. Indian Z. plucheoides, Griseb., but dif 
fering in its larger heads, broad smoothish obtuse involucral scales, ete. 
H. 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 to9 mm. 
Jong; 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 £. 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 Z. sordidum now shows that the latter 
is quite distinct, being in fact of the Hebeclinium group. H. Loesenertt 
has also been collected by E. W. Nelson along the Cuicatlan road, Valley 
of Oaxaca, altitude 2,100 to 2,400 m., 3 October, 1894, no. 1549 ; by
