PHILIPPINE URTICACEAE, II. 301 
probably tetranierou?; '^O flowers fj'oin one receptacle o1* liur. Sci. S1,S0, 
a good but not perfect match for Cmning's plant, were all pentanierous. 
Adding E. innnatim'rvium and E, variahile, both tetrainerous, and other 
species herein and previously described, there are now known in the 
Philip]>ines 31 species with tetranierous flowers, 1) with pentanierous 
flowers, while those of 8 species are still unknown. Decision upon the 
relative importance of the character will depend largely upon the opinions 
held of the nature of the 31 and the 9 respectively, so far at least as 
our species are concerned, and it must be confessed that the weight of 
previous opinion regarding these or those most similar to them, would not 
set much value upon it. Yet it does separate 9 species, five of them 
having much similarity to one another, while the other four, E, simulans, 
E. longifoUum, E, ohtu^iiisculum, and E. rontigiuini have a diiTerent ap- 
pearance from the other four but again much resemblance to one another. 
Much work must be done upon species of other countries before a final 
opinion can be passed.
