Avaust 8, 1910] A DECADE or New PLANTS 687 
along the ridges; pappus 4 to 6 mm. long, equal, creamy 
white in the young state, finely scabrid. 
Type specimen 11618, A. D. E. Elmer, Todaya (Mt. Apo), 
District of Davao, Mindanao, September, 1909. 
Discovered in moist humus covered fertile soil of woods 
at 3500 feet of mount Calelan. It was also observed along 
the Sibulan and Baruring rivers at the same elevation. The 
Bagobos call it ‘‘Igmay’’. Its profuse purplish blue or pink 
flowers are seen from a long distance. 
This species is not the same as Elmer 11289 from the 
same locality and which I take to be V. arborea ( Wall.) 
Ham.

regularly wadded toward the base; branches quite laxly re- 
branched above the middle, the twigs ascendingly curved, 
short yellowish brown puberulent or pubescent; wood rather 
hard, yellowish white, odorless and tasteless, quite heavy. 
Leaves subchartaceous, suberect, much paler beneath, tips re- 
curved, quite numerously scattered along the branchlets, al-

long, nearly as wide, short fulvous pubescent, the lower
