acute, margin undulate-dentate, H-2 in. long, |-1 in. wide, glabrate 

 or sparsely puberulous especially on the nerves beneath ; lateral 

 nerves 5-6 on each side, arcuately ascending ; petiole f in. in the 

 lower leaves, becoming much shorter (less than J in.) in the upper- 

 most. Stipules obsolete. Receptacle solitary, many-flowered, on 

 a long slender stalk, scarcely succulent, green, pubescent when 

 young, broadly turbinate, 3-4 lin. in diam,, surface elliptic, the 

 margin produced into 5-8 (rarely 9) narrow tapering bract-arms, 

 1-3 lin. long, with sometimes short teeth between ; bract-arms 

 more or less spreading or suberect, puberulous with ciliolate margin ; 

 stalk pubescent, shorter than the petioles, but becoming longer 

 in the fruit. Male flowers 2-androus ; perianth broadly 2-lobed ; 

 female dispersed among the male. Style projecting above the level 

 of the stamens, then shortly 2-fid. Endocarp globose-trigonous, 

 whitish, about J lin. in diam., tuberculate. — Bureau in DC. Prodr.

 creeping horizontal rhizome about 2 lin. thick, sparsely hairy, 

 hairs very short, bearing fibrous roots at the nodes and erect leaves ; 

 internodes |-1 in. long, sometimes much shortened. Leaves thinly 

 parchment-like when dry, varying in shape on the same plant, 

 orbicular-cordate, broadly ovate or elliptic, apex rounded, blunt 

 or bluntly acuminate, generally more or less emarginate, base more 

 or less cordate, margin repand or more or less undulate, 3-8 in. long, 

 2|-3J in. wide, shining, dull green and glabrous above, paler and 

 obscurely puberulous on the veins beneath ; venation conspicuous 

 betieath ; lateral nerves 4-6 each side, ascending somewhat and united 

 by a continuous vein well within the leaf -margin to apparently 

 glandular depressions in which run short veins ; reticulation con- 

 spicuous ; petiole stout, more or less densely covered with short 

 hairs, 3-9 in. long. Stipules large, triangular-ovate with a midrib 

 prolonged into an acumen, J- J in. long, sometimes persisting after 

 the fall of the leaf. Inflorescence solitary, axillary ; stalk generally 

 shorter than the petiole, puberulous as is the outside of the open 

 cup-shaped orbicular receptacle; disc about J in. in diam., with a
