This proposed new genus, which is here dedicated to the memory of the author’s 
compatriot, Dr. H. Wawra, Ritter von Fernsee, of the Austrian Exploring Ex- 
pedition, consists of a single remarkable species, of which only three male and 
one female trees are in existence. It is evidently related to Phyllanthus. Owing 
to the fruit being a berry it would come closer to Bischofia, from which it, how- 
ever, differs in the presence of a discus and the fasciculate inflorescence.

This very interesting and remarkable tree, for which an old native Hawaiian 
gave the name Mehamehame, is exceedingly rare, only three males and one female 
tree being in existence. In regard to the native name, the writer is not inclined 
to accept it. The outward appearance of the tree resembles somewhat our Ha- 
Waiian Antidesma, which are also called Hame or Mehame or Mehamehame. The 
old native might have easily taken it for such. It is very doubtful if the natives 
ever had a name for the tree, as it is peculiar to such a small area, located in 
‘a most inhospitable place on the southern flanks of the great voleano Mauna Loa 
on rough aa lava flows, made accessible only very recently. 
It was discovered by the writer in the above locality at an elevation of 2000 
feet, called Kapua, during the month of February, 1912; but was at that time 
neither in flower nor in fruit. A eareful search of the ground beneath the 
trees, revealed no sign of seeds of a previous season. This, however, was ex- 
plained on a later visit in the month of July (15), 1912, in company with Mr. 
W. M. Giffard, when it was found that the trees first examined were all male and 
in flower. Only one other tree was seen, which fortunately turned out to be a 
female tree bearing fruit. It is a striking tree of medium height, and is quite
