116 MR. H. N. RIDLEY ON PLANTS 
Leaves drying pale greenish grey, nervation well marked on the upper side, less clear 
on the lower; petioles 2-3 mm. long, stoutish, channelled above, glabrous. Segments of 
calyx 0:75 mm. long. Corollas barely 5 mm. across, the undivided part 0:5 mm., the 
lobes 2:5 mm. long. Pollinia 0:3 mm., gland about 0:1 mm. long. 
Allied to the last, but unlike it by reason of the broader, thinner leaves and the long 
and very slender peduncles, the smaller flowers, the corona reaching nearly to the top of 
the gynostegium, and the short appendages to the anthers.

This is evidently closely allied to H. microphylla, Schlechter and H. pulchella, 
Schlechter, as Schlechter’s figure and descriptions show, but it has certain points - 
of difference which seem to prevent its being considered conspecific with either; these 
differences are shown in the accompanying table. As Schlechter observes, the leaves 
of these and one or two other species greatly resemble those of Dischidia.
