So far as this is a sufficient test, the character seems reliable. It may- 
be added that where different collection numbers have been referred to the 
same species, their flowers agree in this respect in almost every case 
investigated. The only exception known to me is with E. podophyllum 
Wedd., normally tetramerous. Two collections so identified, Merrill 6171 
and Bur. Sci. 9356, have been noted on the sheets as pentamerous. 
Further examination of the former showed that of two flowers dissected 
one was tetramerous and one pentamerous ; the latter was preponderating^ 
pentamerous, four receptacles giving 22 pentamerous flowers and only 
3 tetramerous. There are four other Philippine species about which 
discordant statements have been made. E. simulans was described 3 
as tetramerous or pentamerous, dissection of six additional flowers showed 
that they at least were all pentamerous. Mr. Elmer’s examination of 
the flowers of E. philippinense disclosed both numbers, mine showed five 
only. 4 Similarly in E. spinulosum./ he found trimerous as well as tetra- 
merous flowers, I found the latter number only. 5 1 
Finally, Weddell calls E. longifolium doubtfully tetramerous. 0 Eleven 
flowers were examined from one receptacle of the broad-leaved plant of 
Cuming 1,56 , ten were pentamerous, the eleventh tvas in poor condition but
