PITTIER — PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 103 



at the base, smooth, light green above, glaucous underneath; primary veins opposite 

 or alternate, ascending, the broad interspaces finely reticulate; margin smooth, revo- 

 lute; a tuft of gland-like organs on the main nerve on the upper face and near the 

 base of the leaf blade. 



Flowers greenish, in pedunculate axillary umbels; peduncles (i to 10 mm. long, 

 subfurfuraoeous; pedicels brownish, furfuraceous, provided with small lanceolate, 

 hairy bracteoles. Calyx 4 mm. long, with 

 rounded lobes 2 mm. broad, hirsute outside, 

 smooth inside, and ciliate on the margins. 

 Corolla 4 to 7 mm. long; tube 2 to 3 mm. 

 long, shorter than the calyx; lobes elliptic, 

 rounded at tip, smooth and ciliolate. Seg- 

 ments of the staminal crown lanceolate, by 

 one-third shorter than the anther-bearing 

 lamina 1 . Lamina rounded, perfectly trans- 

 parent at tip and dotted with starry, gland- 

 like, minute, opaque spots. Translatoria 

 rather small; pollinia about 0.3 mm. long; 

 corpusculum about 0. IS mm. long. Ovary 

 bilocular, 1 to 1.5 mm. long, smooth; stig- 

 matic head pointed and bifid. 



Follicles not known. 



Costa Rica: Along roads at Nicoya, 

 Tonduz, flowers, April, 1900 (Instituto fi's. 

 geog. Costa Rica no. 13909; U. S. National 

 Herbarium no. 577899, type). 



This species differs from the other de- 

 scribed Central American forms by having 

 the scales of the staminal crown shorter 

 than the staminal laminae; the pollinia are 

 also reduced in size; the leaves are some- 

 what similar to those of M. edulis Watson, 

 but are distinctly founded, and not sub- 

 decurrent, at the base, blunt and not 

 acutely pointed at tip; their shape is more 

 constant and the flowers in the umbel are 

 more numerous. 



Several specimens in the U. S. National 

 Herbarium, collected in Central America 

 have been referred to M, maculata Hooker, 

 but to my mind these identifications are 

 very doubtful, and the whole section needs 

 a thorough revision.

A vine, sub voluble or most generally creeping on low bushes, fallen trunks, or 

 walls. Stems hairy, rounded, little ramified. 



Petioles 2.5 to 4 cm. long, slender, hairy. Leaf blades 4 to 7 cm. long, 1 .5 to 3.5 cm. 

 broad, oblong-lanceolate, acuminate, shallow -cordate at base with broad sinus and 

 rounded auricles, sparsclyhairy,dark green above, paler with prominent brownish-hairy 

 venation beneath. Two or more small glands at the insertion of the blade on the petiole. 



Inflorescences cymose, axillary, unilateral, 3 to 5-flowered. Peduncles, pedicels, 

 and bracteoles hairy; peduncles 1 to 2 cm. long; pedicels 1 to 3 cm. long; bracteoles 

 small, linear. Calyx shortly campanulate, membranous, hairy outside, smooth
