GREENMAN. — NEW ANGIOSPERMS FROM MEXICO. 95 



is placed under Erigeron. Owing to the several discrepancies between 

 Klatt's published description and the original specimen an entirely new 

 characterization is here drawn. 



Erigeron repens, Gray, Syn. Fl. i. pt. 2, 17. Specimens collected 

 by Mr. C. G. Pringle on sand dunes near the City of Vera Cruz, Mexico, 

 22 June, 1901, no. 9673 (hb. Gr.), are clearly referable to the above 

 species, hitherto known only from the sandy sea-coast of Texas and 

 Louisiana. 



Gnaphalium Altamiranum. Densely lanate-tomentose through- 

 out: stem 1.5 to 2 m. high, much-branched above : leaves sessile, auricu- 

 late-clasping, lanceolate, 8 to 16 cm. long, 0.5 to 1.5 cm. broad, acuminate, 

 acute, entire, 3-nerved, broadest near the base : inflorescence a many- 

 headed compound corymbose cyme : heads during anthesis about 6 mm. 

 high, nearly or quite as broad : involucre campanulate, usually 5-seriate ; 

 scales of the involucre whitish or pale-stramineous, the outer broadly 

 ovate, obtusish, the inner narrowly oblong, obtuse : flowers numerous : 

 perfect flowers about 10. — Mexico. State of Morelos : mountains 

 above Cuernavaca, altitude 2460 m., 2 February, 1899, C. G. Pringle, 

 no. 8041 (hb. Gr.). 



The species here proposed is allied to Ganphalium Wrightli, Gray, 

 but differs in having larger leavers, which are relatively broad at the base, 

 and gradually narrowed to the tip, also by somewhat larger and more 

 numerously flowered heads, and broader outer involucral scales. 



Gnaphalium chartaceum. Stem erect, 1 to nearly 2 m. high, 

 freely branching, glandular-hirsute : leaves sessile, round-auricled, half- 

 clasping the stem, lanceolate to somewhat oblong-lanceolate, 3.5 to 8 cm. 

 long, 0.5 to 2 cm. broad, acute to acuminate-acute, entire or slightly 

 undulate-margined, hirsute or glandular-hirsute and somewhat arachnoid 

 in the early stages, especially on the under surface, hirsute on the mid- 

 rib beneath : inflorescence a terminal compound many-headed corymbose 

 cyme: heads 5 to 6 mm. high: involucre subcampanulate ; scales imbri- 

 cated in 4 series, ovate, obtuse or obtusish, almost pure white or some- 

 what cream-colored, firm or chartaceous in texture : perfect flowers 15 

 to 25; pistillate flowers numerous. — Mexico. State of Jalisco: on 

 hillsides and banks near Guadalajara, 22 November, 1888, C. G. Pringle, 

 no. 1827 (hb. Gr.), distributed as " Gnaphalium decurrens, Ives, var." 

 State of Puebla: near Tehuacan, 22 December, 1895, C. G. Pringle, 

 no. 7033 (hb. Gr.). 



G, chartaceum is readily distinguished from G. decurrens, Ives, with 

 which species it has hitherto been confused, by the sessile auriculate half-
