which emerges from the persistent cup-shaped calyx, is oblong, 1 to 

 1.0 cm. iu length, 6 to 7 mm. thick, pale green and closely stellate- 

 lepidote over the slightly corrugated surface. 



Stenamadenia macrophylla. Stems covered vrith 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 cm. 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 Verapaz, 

 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 hignoniaejiora^ 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 cm. 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. 



Stemmadenia tom.entosa. Shrub, 3 to 5 m. 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 ridire about the stem in the axil 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 " S. mollis, Benth. ? " The nearest ally of ^S". tomentosa is apparently
