16. PIPTURUS Wedd. 
Pipturus dentatus comb. nov. 
Pouzolzia dentata C B. Rob. in Philip. Jouni. 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 confirnuition of Mr. Elmer's 
note, cited by me in the original description of this species, as uell of my com- 
ments thereon. But it has forced the conclusion that the characters depended 
upon to differentiate Pipturus from Pouzolzia are not merely unreliable as such, 
but tliat many statements regarding them, made by myself as well as by others, 
are actual errors. Several, including the most important, are here quoted.
