GREENMAN. — PHANEROGAMS. 489 
rather closely appressed-pubescent cymes: bracts and bractlets linear- 
subulate: flowers 4-merous: calyx-tube densely covered with a white 
appressed pubescence ; lobes subequal, about 1 mm. long, obtuse, ciliate : 
corolla white, 3 mm. long, villous-pubescent on the throat and on the 
tube: fruit not seen. — Collected by C. G. Pringle on hills near Tampico, 
16 June, 1897, no. 6641. 
Lobelia tarsophora, Seaton in Mss. Stem erect, simple or 
branched at the base, 3 to 4.5 dm. high: leaves petiolate, membrana- 
ceous, ovate-lanceolate, acuminate, unequal and oblique at the base, un- 
dulate and mucronate-denticulate, nearly smooth, 5 to 7.5 cm. long, 2.5 
cm. broad. racemes long, loosely flowered: bracts 2 mm. in length: 
pedicels 10 to 16 mm. long, spreading, becoming horizontal in fruit: 
corolla blue and white, 4 to 5 mm. in length, the lips unequal: calyx- 
tube becoming hemispherical in fruit, its rim and ribs persisting after the 
dehiscence and fall of the small globose half inferior capsule.— Collected 
by Henry E. Seaton on river banks near Cordoba, altitude 830 m., 20 
August, 1891, no. 417. This species is well marked by its foliage, 
horizontal pedicels, and the peculiar persistence of the rim and nerves of 
the calyx-tube as a basket-like frame after the dehiscence of the capsule. 
n habit it most nearly resembles Z. novella, Rob. : 
Zexmenia Pringlei. Perennial, stems striate, covered with an 
arachnoid pubescence: lower leaves opposite, the upper alternate, short- 
petiolate, ovate, 1.5 to 3 em. long, two thirds as broad, obtuse at the 
"ays oblong, 12 mm. long, nearly one half as broad ; akenes triangular 
Coming somewhat verrucose at maturity: disk-flowers about 1 cm. 
long ; pappus bisetose with minute intermediate scales; mature akenes 
laterally compressed, with a narrow ciliated cartilaginous wing, glabrous 
or a little roughened, about 4 mm. long. — Collected by C. G. Pringle 
ine hills near Tehuacan, altitude 2000 m., 5 August, 1897, no.
