Chaowasku , comb. nov. Basionym:— Mitrephora merrillii C.B.Rob. (1908: 67) . Griffithianthus merrillii (C.B.Rob.) W.H.Brown ex Merrill (1915: 231) . Mitrephora ferruginea Merrill (1904: 16) , nom. illeg. TYPE:—THE PHILIPPINES . Luzon, Bataan Province : Mt. Mariveles, January 1904 , Merrill 3728 (PNH (destroyed), lectotype (here designated) NY!, isotypes BM!, P!), in fruit. Observations: —Originally, the syntypes of this species consist of disparate elements as stated by Merrill (1915) and Weerasooriya & Saunders (2010) . Nevertheless, no one has designated a lectotype , therefore it is done here. Neo-uvaria merrillii primarily differs from N. acuminatissima in having usually (broadly) wedgeshaped leaf base (whilst usually obtuse to rounded in N. acuminatissima ), larger sepals (4.5–5.0 × 4.0– 4.5 mm in N. merrillii vs. ca. 2.6 × 2.9 mm in N. acuminatissima ) and wider monocarps (ca. 2.2 cm wide in N. merrillii vs. ca. 1.7 cm wide in N. acuminatissima ).
