somewhat yellowish. Stipules 15 mm. long, broadly ovate, 

 acummate and acute, thin, brown, early deciduous. Petioles 

 to 2.5 cm. long, nerved or lightly costate toward the base, the 

 summit gradually widening into the leaf-base. Blades 7 to 

 10 cm. long, 3 to 5 cm. broad, oval or ovate and abruptly acumi- 

 nate and acute at both ends, thickish, light-gray beneath, with 

 the venation strongly prominent, deep-green above, the second- 

 aries 9 or 10 on a side, strongly falcate-ascending and connect- 

 ing near the margin, connected by numerous rather crooked 

 tertiaries. Peduncles, in flower, about 2.5 cm. long, slender, 

 bifid, the branches of about equal length, strongly recurved! 

 each bearing a single dense row of flowers, on very short and 

 stout pedicels. Calyx nearly 2 mm. long and broad, campanu- 

 late, obscurely ribbed, the margin minutely toothed. Corolla- 

 tube 12 mm. long, narrowly infundibular, the 5 lobes valvate, 

 with the summits strongly inflexed. Open flowers not seen.

 oles to 5 cm. long, slender, somewhat dilated at the "articulated 

 base, blades i to 2 dm. long, and 6 to 10 cm. broad, broadly

 acuminate and acute; thin, entire, gray-green beneath, green 

 and pilose above, the venation slightly prominent above, the

 Bracts setaceous, brown, 4 or 5 mm. long, deciduous. Flowers

 what quadrilateral, 3 mm. long, the margin sinuately lobed, 

 lightly everted in flower. Corolla pubescent, salver-form, the
