GREENMAN. — NEW ANGIOSPERMS FROM MEXICO. 97 
inflorescence corymbose ; heads numerous, small, 3 mm. long, disposed in 
glomerules: involucral scales about 3-seriate, pale-stramineous, imbri- 
cated; the outer scales ovate, obtuse, brownish especially at the base, 
the inner linear-oblong or slightly oblanceolate, acutish: pistillate flowers 
about 14: perfect flowers few, usually two. — Mexico. State of Oaxaca: 
altitude, 1750 m., — July—August, 1900, Conzatti & Gonzdlez, no. 1012 
in part (hb. Gr.). 
Gnaphalium oblanceolatum. Densely white lanate-tomentose 
throughout: stem erect, 4 to 5 dm. high, ligneous at the base, simple or 
branched, leafy: leaves sessile by a half-clasping base, oblanceolate, 2 to 
7 em. long, 0.5 to 1.5 em. broad, entire, white lanate-tomentose on both 
surfaces or arachnoid above, also bearing on the upper surface crowded 
crisp hirsutish hairs: inflorescence terminating the stem and branches in 
a leafy corymbose panicle: heads crowded : involucre about 5 mm. high; 
scales imbricated, acute, pale yellow.— Mexico. State of Oaxaca: 
Cerro de San Felipe, altitude 1800 m., 21 August, and 1st September, 
1897, Conzatti & Gonzdlez, nos. 385 and 696 (hb. Gr.). 
The species here proposed is described from young flowering specimens. 
In general appearance it approaches most closely G. pannosum, Gray, 
_ from which, however, it differs in the more leafy stem and in the oblan- 
ceolate leaf-outline. 
GNAPHALIUM PURPUREUM, L., var. macrophyllum. Stem 6 dm. 
high, lanate-tomentose: leaves oblanceolate or oblanceolate-spatulate, 0.5 
to 1.5 dm. long, 1 to 1.5 em. broad, obtuse or submucronate-acute, arach- 
noid-pubescent above in the early stages and later glabrate, densely and 
permanently white-tomentose beneath: inflorescence racemose-paniculate : 
involucral scales brownish or with a green base and a rich brown tip. — 
Costa Rica. El Copey, altitude 1800 m., February, 1898, Ad. Tonduz, 
no. 11,771 (hb. Gr., and hb. Inst. Phys.-Geog. Cost. Ri.). 
It is quite possible that the variety here proposed may prove eventually 
to represent a distinct species, but in the present confused state of the 
genus, particularly the subtropical species, it seems to the writer best to 
regard the above plant as a variety of G.purpureum, L., especially as its 
chief distinguishing characters are the size of the plant, the very large 
leaves, and the paniculate inflorescence. 
Clibadium anceps. Small tree, much-branched : ultimate branches 
Somewhat flattened, decussately 2-edged, minutely strigose-pubescent : 
leaves opposite, petiolate, ovate, 8 to 12 cm. long, 4 to 6 cm. broad, acumin- 
ate, acute, remotely denticulate, more or less revolute-margined, cuneate at 
the base, hirtellous-pubescent upon both surfaces, glabrate and somewhat
