acute, margin undulate-dentate, 14-2 in. long, 3-1 in. wide, glabrate 
or sparsely puberulous especially on the nerves beneath ; lateral 
nerves 5-6 on each side, arcuately ascending ; petiole ? in. in the 
lower leaves, becoming much shorter (less than } 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 4 lin. in diam., tuberculate-—Bureau in DC. Prodr.

19. D. picta, Bureau in DC. Prodr. xvii. 277. A herb with a 
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, 
24-33 in. wide, shining, dull green and glabrous above, paler and 
obscurely puberulous on the veins beneath ; venation conspicuous 
beneath ; 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, }~4 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 3 in. in diam., with a 
regular margin of short inflexed bluntly triangular teeth. Male 
flowers typically 2-androus; perianth broadly 2-lobed. Female 
flowers distributed through the receptacle; style 2-branched.—
