ROBINSON. — MEXICAN PLANTS. 841 
base and without definitely marked throat; segments ovate-oblong. — 
Collected in Oaxaca by C. G. Pringle, on Monte Alban, altitude 1,800 
m., 8 October, 1894, no. 4959, type (in herb. Gray); by L. C. Smith 
on mountains of San Juan del Estado, altitude 2,100 m., 4 November, 
1894, no. 274; and by C. & E. Seler, above Porian, 27 November, 
1895, no. 1547. This species stands very close to EZ. Loesenerti and may 
eventually prove a variety of it, but as yet, although each species has 
been independently secured by three collectors, no intergradation has 
been observed. The differences are as follows: E. Smithii has smaller 
leaves of a more deltoid contour and with a cinereous rather than ochra- 
ceous indumentum ; its inflorescences are considerably smaller, while the 
involucral bracts are larger, more herbaceous, and less closely appressed ; 
finally the teeth of the corolla are, on careful comparison, longer and 
ovate-oblong rather than deltoid as in Z. Loesenerit.

course, be adopted.

MIKANIA ER1opHora, Sch. Bip., var. chiapensis. Pubescence 
more hirsute than in the type, the hairs spreading, not at all felted or 
interplexed: leaves large, deeply cordate, becoming 2.2 dm. long, and 
1.7 dm. broad: involucral scales early glabrate. — Collected by E. W. 
Nelson at Chicharras, Chiapas, Mexico, altitude 900 to 1,800 m., 6 Feb- 
Tuary, 1896, no. 3769. This variety has much the habit of JZ pyrami- 
data, J. D. Smith, but that has the leaves smaller, rounded at the base, 
and the pubescence subappressed on the pedicels. 
Porophyllum brachypodum. Shrub, scarcely or not at all glau- 
cous; stems somewhat rigid, branched toward the end, lucid: leaves 
(only the upper ones shown) lanceolate to linear, narrowed to an obtus- 
ish glanduliferous point, cuneate at the base, entire, 3.5 cm. long, 4 to 8 
mm. broad ; petioles 4 mm. long; glands on the blade all marginal, large, 
subremote, on the narrower leaves often alternate: pedicels 5 to 8 mm. 
long, slightly clavate, spreading; involucral bracts oblong, rather broad,
