16. PIPTURUS Wedd. 
Pipturus dentatus comb. nov. 
Pouzolsia dentata C. B. Rob. in Philip. Journ. Sci 6 (1911) Bot. 7. 
Material of this species, seen by me in a fresh condition, Phil. PI. 807 Merrill, 
from near Pauai, Benguet, has led to a complete confirmation of Mr. Elmer’s 
note, cited by me in the original description of this species, as well of my com- 
ments thereon. But it has forced the conclusion that the characters depended 
upon to differentiate Pipturus from Pousolzia are not merely unreliable as such, 
but that many statements regarding them, made by myself as well as by others, 
are actual errors. Several, including the most important, are here quoted.
