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

 altitude, 1750 m., — July-August, 1900, Conzatti fy Gonzalez, 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 cm. long, 0.5 to 1.5 cm. 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 fy Gonzalez, nos. 385 and 696 (hb. Gr.). 



The species here proposed is described from young flowering specimens. 

 In general appearance it approaches most closely 67. pannosum, Gray, 

 from which, however, it differs in the more leafy stem and in the oblan- 

 ceolate leaf-outline. 



Gnaphalium purpureuji, 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 cm. 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. lust. 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.purpurenm, 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-pubesceut upon both surfaces, glabrate and somewhat
