which emerges from the persistent cup-shaped calyx, is oblong, 1 to 
1.5 em. in length, 6 to 7 mm. thick, pale green and closely stellate- 
lepidote over the slightly corrugated surface. 
Stemmadenia macrophylla. Stems covered with a grayish bark 
and dotted with lenticels: leaves oblong-obovate to oblong-lanceolate, 
including the petiole 1 to 2.5 dm. long, 4 to 7.5 cm. broad, acuminate, 
entire, narrowed below into a short (5 to 15 mm. long) petiole, glabrous 
upon each surface, dark green above, slightly paler beneath: inflores- 
cence subracemose at the bifurcation of the branches, few-flowered; 
peduncles 3 em. long: calyx deeply 5-parted, segments unequal, the two 
outer shorter, 4 to 5 mm. long, somewhat narrowed toward the apex, 
the inner oblong or slightly obovate-oblong, about 7 mm. long, rounded 
at the apex: corolla tubular-funnelform, about 6 cm. long, tube nar- 
rowed below, ampliated above, lobes spreading: fruit not seen. — Col- 
lected by H. von Tuerckheim at Pansamala, Depart. Alta Vetapaz, 
altitude 1,100 m., January, 1886, no. 981. 
This number (no. 981) of Mr. John Donnell Smith’s collection was ori- 
ginally distributed as “Odontadenia? ”* and subsequently corrected to 
Stemmadenia bignoniaeflora, Miers, and under this name Donnell 
Smith’s no, 1800 was also distributed. The latter species is character- 
ized as having a calyx 1.3 to 1.5 em. long. Stemmadenia macrophylla 
on the other hand has the calyx less than half this length; thus by the 
character of the calyx alone the two species may be readily distinguished. 
temmadenia tomentosa. Shrub, 3 to 5m. high: stems some- 
what dichotomously branched above, covered with a grayish bark and 
dotted here and there with minute lenticels: leaves opposite, ovate- 
oblong, or slightly obovate, short-acuminate, entire, narrowed at the 
base into a short slender petiole, glabrous above, densely. soft-tomentose 
beneath ; petioles slightly connate below and forming with the persistent 
leaf scar a narrow ridge about the stem in the axi! of which is a continu- 
ous row of minute glands similar to those of the calyx: rather close 
floral clusters terminating the branches: flowers large: calyx deeply 5- 
parted, lobes broadly ovate, acute, about 5 mm. long: corolla yellow, 
tubular-funnelform, greatly ampliated above, narrowed below, usually 
more or less twisted in the throat, and with large subrotund spreading 
lobes: mature fruit not seen, —Collected by C. G. Pringle in lava beds 
near Zapotlan, State of Jalisco, 19 May, 1893, no. 4370, and distributed 
as “8. mollis, Benth.?” The nearest ally of S. tomentosa is apparently
