216 LEAVITT. 



browner pubescence on tlie inflorescence, shorter ovary and pedicel, shorter mcn- 

 tum and narrower angle between men turn and ovary, more fleshy consistence of 

 the flower, heavier veining of the perianth (the veins especially deeply stained 

 in the lateral sepals), somewhat wider petals, and larger lip. Dried, the interior 

 of the sepals and petals appears very dark. 



A third specimen from Mount Mariveles (Lamao River, March, 1905, For, 

 Bur. 2152 Borden) perhaps belongs to the above species, though the peduncle 

 is very slender, the consistence of the floral parts is much less firm than in 

 typical E. Whitfordii. the petals are shorter, the lip much smaller and propor- 

 tionally broader distally, tapering toward the base, and the column smaller and 

 straighter with the foot. The floral parts are described by the collector as 

 yellow with purple center. It remains to be seen whether this is a distinct 

 species, or whether all the specimens cited (with Whitford 3.30, from the same 

 region, the flowers too old for determination, but the lip apparently acuminate) 

 belong to a single fluctuating species. 



In Mindanao. Major E. A. Mearns and Mr. W, I. Hutchinson collected seven 

 specimens of an Erin belonging to this section, which I have no hesitation in 

 describing as a new species.
