Type specimen 12460, A. D. E. Elmer, Magallanes (Mt. 
Giting-giting), Province of Capiz, Island of Sibuyan, May, 1910. 
Climbing upon and sprawling over thickets bordering 
the sand gravelly banks of the Pauala river at 750 feet.

Differs from M. umbellata Linn. (M. microcephala Bartl.), 
in having fewer and larger heads upon twice as long peduncles; 
although the leaves are quite similar there are distinct floral 
differences. Merrill’s specimen 576 from Culion island is 
referable here.
