petioles of almost equal length: heads rather few, very loosely dis- 
posed upon slender subdichotomous branches: scales of the involucre 
lance-linear, acuminate, a little over 2 lines in length, covered with 
fine dark glandular pubescence : corollas white, externally roughened 
and with a pubescent limb; tube exserted: achenes slightly rough- 
ened, 1} lines long; pappus lacerate coroniform; ariste none. — 
Dry hills near Patzcuaro, Michoacan, November, 1891 (n. 5051). 
The same as Bourgeau’s no. 3331, from Escamella, near Orizaba, 
October, 1865. oe 
Evpatorium SaAttivaril, Schultz Bipontinus. Rootstock hori- 
zontal, branching: stems several, erect, purple, pubescent, glandular 
above, 1-2 feet high, throwing out several small weak branches near 
the base: leaves ovate, acute, coarsely serrate, abrupt at the base, 
pubescent on both surfaces, 1-1} inches long, more than half as broad: 
petioles 3-4 lines in length: heads rather few, aggregated in small 
terminal corymbs, 4 lines high, about 50-flowered : involucral scales 
subequal in about two series, lanceolate, acute, ciliate, striate, the outer 
glandular: corolla tubes slender, as long as the ample throat: achenes 
slender, slightly curved, 1} lines in length, hispidulous, callous-tipped 
at the base. This apparently good species of Schultz Bipontinus, — 
founded upon Schaffner’s no. 298 from the Val de Mexico, October, 
1855, seems never to have been described. It has since been collected 
by Bourgeau in the same place (n. 818), and by Mr. Pringle in — 
pine woods, Nevado de Toluca, State of Mexico, September, 1892 
“(n. 4286). : 
BRICKELLIA sQuaRROSA. Stems subsimple, 2 feet or more ™ 
height, terete, covered with short dense pubescence, somewhat glandu- 
lar roughened above. leaves opposite, oblong-lanceolate, obtusish, 
more or less acute at the base, crenate, 1}—2 inches in length, very 
rough and somewhat rugose above, prominently reticulated, hispid om 
the veins and black punctate on the surface below: petioles 4 lines 
long : heads 7 lines long, about 12-flowered, in a subsimple raceme + 
pedicels an inch long: the outer scales of the involucre shorter, he™ 
baceous, squarrose, glandular ; the inner thin, purplish-striate, acul®’ : 
corolla lobes minutely callous-tipped: achenes pubescent: pappus 9P _ 
pressed-barbellate.—— Mountains near Patzcuaro, Michoacan, Dece®™ 
ber, 1891 (n. 5054). 7" 
SABAZIA SUBNUDA. Root of many fibres from a short rootstock + 
stems slender, erect, pubescent, almost naked, bearing one to three 
large long-peduncled heads: radical leaves ovate-elliptical, obtuse 
entire, triply nerved, narrowed to a short broad petiole, ciliate, glabrous —
