884 LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 50 
PELLIONIA Gaud. 
Pellionia (n. sp. in ms. by C. B. Robinson.) 
Field-note:—Large and succulent tufts; stems many from 
the same root cluster, ascending and numerously rebranch- 
ed, green, succulent, the ranker ones 7.5 cm. in diameter 
at the base, from 1 to 3 m. high; leaves quite thin, 
flat, descending, paler beneath; inflorescence erect, ascend- 
ing, the pistillate pale green, the staminate dull pink; the 
buds of the stamens bursting with a force thereby scatter- 
ing the pollen in a cloud; the 5 filaments and anthers 
only slightly tinged with red. Very common and in favor- 
able places forming dense jungles in moist fertile soil 
or upon rotten stumps or about bases of large trees in a 
humid forested basin at 4000 feet. This same species oc- 
casionally became epiphytic and formed dense clumps about 
its support. The Bagobos call it ''Dadar."

ELATOSTEMA Forst. 
Elatostema whitfordii Merr. 
Field-note:—Large rank tufts; stems easily breaking, suc- 
culent,, green, smooth, obscurely fluted, at the base usually 
reclining, ultimately erect, 2.5 to 7.5 em. thick near the ground 
and gradually decreasing in thickness, about 2 m. high; 
leaves limp, in alternatingly distichous rows, suberect, more 
crowded toward the apex, dark green except the lighter 
lower side, the young ones very light green; infrutescence 
upon greenish white plates usually of a lobed squarrish shape, 
arranged along the stem on the upper side and even in 
‘the leaf axils; the short green pedicels usually recurved, 
thereby turning the fleshy receptacle away from the stem; 
seeds minute, brown, numerous; bracts very short or ob- 
solete. In exceedingly moist earth among rocks in deeply 
shaded ravines along the Baruring river at 3500 feet.
