tint, the edges of the lobes green, and the corolla green extern- 

 ally. Rare in clearings near Mameteca, below 1,500 feet, May 

 and June. Collected June 3-" (Herbert H. Smith, Colombia, 

 No. 2094.) 



Species unique in the distinct poUinia, but certainly a Mars- 



denia. 



Marsdenia inelegans. 



Young leaf-surfaces minutely puberulent underneath. 

 Branches twisted, terete, striate. Leaves 5 to 7 cm. long, in- 

 cluding the petiols-like base, 3 to 5 cm. broad, broadly oval or 

 rotund, abruptly contracted into a narrowly cuneate base about 

 one-fourth of the total length and with a very abruptly short- 

 pointed acute summit, the principal veins slightly prominent 

 above, the secondaries 5 or 6 on each side, widely spreading, 

 little curved but crooked and bifurcating toward the end. 

 Peduncle (but one seen) i cm. long, with a lance olate foliaceous 

 bract at the base and bearing 2 umbels, about 2 cm. broad, the 

 pedicels 3 or 4 mm. long, stout, angled, thickened upward. 

 Expanded calyx 5 mm. broad, divided nearly to the base, the 

 lobes ovate, obtuse. Corolla-tube hemispherical, about 4 mm. 

 broad, the lobes about half of its length, recurved, obtuse. 

 Crown of 5 purple, fleshy, concave appressed obtuse scales, 

 as long as the stamen-column. Anthers with 5 short, triangular, 

 obtuse, hyaline inflexed appendages. Stigma small, circular, 

 depressed. Pollinia pear-shaped, the filaments erect, then 

 incurved, dilated near the corpuscles and less so near the pol- 

 linia. 



"Twining to 20 feet, the corolla greenish -brown. Rare in 

 dry forests and thickets below 1000 feet. May to June. Col- 

 lected 3 miles S. E. of Bonda, 500 feet. May 30." (Herbert "H.

 Marsdenia asclepioidea. 



Glabrous, sterns slender, terete. Petioles 2 to 3 cm. long, 

 deeply channelled above. Blades 10 to 20 cm. long, 5 to 10

 obtusish summit, thin, drying brown, the venation rather 

 coarse, not prominent, the secondaries 8 or 10 on a side, stout, 

 spreading, then strongly falcate and connecting near the margin, 

 between them one or more minor ones, the remaining 

 venation loosely branching. Peduncles shorter than their 

 leaves, mostly much shorter, slender, the flowers umbellate, the 

 umbels many- flowered, the pedicels about 3 cm. long, slender. 

 Calyx I cm. or more broad, parted nearly to the base, the lobes 

 broadly ovate, obtuse, papillose externally with broad smooth
