pedunculate pistillate flowers and those disposed in cymes, between ample, many times branched staminate cymes and condensed once twiceor ramified ones, between large thin, cordate, hairy leaves and small, subcoriaceous, broadly elliptic, glabrous ones would be hard to reconcile within one species. there Yetseem to be various degrees of intermediacy present in these and other characters between all of the species described from Palau.
acteristics characters, then on the form and size of inflorescences, finally on calyx and corolla char- tions. A factor that complicates this is the difficulty of knowing, in some whichto were found growing cases, together. This which was not often done, as wewere not aware that staminate plants go with which pistillate ones observationsif were not made in the field as there were any problems. Some of our guesses may conceivably be wrong.
