4.2 em. latis ; capitulis pyramidato-paniculatis ca. 5-floris ; involuecri 
squamis viridibus striatis acutissimis vix pubescentibus ; antheris 
apice brevissime appendiculatis. — El] Ocote, Michoacan or Guerrero, 
alt. 300 m., 10 November, 1898, Langlassé, n. 616 (hb. Gray, hb. Berol.). 
Said to be a shrub 1.5 m. high with grayish flowers. 
ium pelotrophum, n. sp., fruticosum 1.5 m. altum ; ramis 
gracilibus teretibus fuscis puberulis ; internodiis ca. 5 cm. longis ; foliis 
oppositis petiolatis ovatis longe acuminatis serratis basi rotundata et 
apice caudato-attenuato integerrimis a basi 3(—5)-nerviis 7-10 cm. 
longis 2-4 cm. latis firmiusculis utrinque viridibus scabriusculis, petiolo 
fusco-puberulo ca. 1 cm. longo; cymis axillaribus glomeruliformibus 
oppositis ca. 12-capitulatis 2-3 cm. diametro, pedicellis 1-5 mm. longis 
teretibus sordido-tomentellis, bracteolis minimis fuscis; involucris 
subcylindrici-campanulatis saepissime 4-floris, squamis ca. 9 valde 
inaequalibus appresse imbricatis lanceolato-linearibus obtusis brunneis 
dorso pilosiusculis, interioribus ca. 8 mm. longis ; corollis albis ex invo- 
lucro longe exsertis ca. 4 mm. longis glabris, tubo proprio gracili in 
fauces cylindricos subaequilongos leviter ampliato, dentibus limbi 
brevissimis suberectis ; achaeniis (immaturis) fuscis obscure granulatis 
quam corollae multo brevioribus ; pappi setis albis rectis ca. 20 sursum 
scabriusculis corollam aequantibus.—In clayey soil on the crest of 
the Sierra Madre in Michoacan or Guerrero, alt. 2300 m., 16 February, 
1899, Langlassé, n. 880 (hb. Gray). This species is clearly related to 
E. tubiflorum Benth. and LF. areolare DC., but may be readily distin- 
guished by its peculiar globular axillary inflorescences and by the fact 
that the pappus is fully as long as the corolla. 
Evpatorivum purpureum L., var Bruneri (Gray), n. comb., foliis 
oblongo-lanceolatis ternis vel quaternis vel quinis serratis firmiusculis 
subtus plus minusve cinerascenti-puberulis vel tomentellis albescente 
reticulato-venulosis ; corymbis planiusculis vel modice convexis. — 
E. Bruneri Gray, Syn. Fl. i. pt. 2, 96 (1884) ; Coult. Man. Rocky Mt. 
Reg. 142 (1885). #. atromontanum Nelson, Bot. Gaz. xxxi. 400 (June, 
1901). H. Rydbergi Britton, Man. 921 (Oct. 1901).—Dr. Gray's 
original characterization of HE. Bruneri was drawn from a very poor 
specimen and is so misleading that it is by no means surprising that 
it has never been rightly understood. The leaves are not opposite, aS 
described, but are in whorls of three. In pubescence, venation, tooth- 
ing, and texture, they correspond accurately with the widely distrib 
uted western form of H. purpureum, which as stated above has received 
two subsequent specific names. ‘The form, although fairly well marked 
in its extreme, appears to pass by easy transitions into the typical form — : 
of E. purpureum and would therefore seem best treated as a variety. -
