Helicia paucinervia Merr., Philippine Journal of Science 17 (1920) 247.

Synopsis: A small tree or shrub, so far known only from a few collectons in the wet lowlands of the south and east of the Philippines. It is distinctive in the completely glabrous glossy appearance and in the four to five main nerves of the leaves. The specimen in US (sterile) indicates that the leaves dry a dark red-purple.

There seem to be few duplicates of the type specimens, the PNH collections of which were destroyed in 1945. Known collections include: Ramos, M. 34610, (holotype - PNH destroyed; duplicate in US is without flowers, other duplicates are not known), April 1919, Mindanao, Surigao del Norte, 300 m; Ramos, M. 34621 April, 1919, Dinagat, iron deposit [two duplicates in P, images online.]; Ramos, M. 83867, 14 Jun 1931, Dinagat, iron deposit; Ramos, M. 84098, 14 Jun 1931, Dinagat, iron deposit.

A recent widely duplicated collection that is tentatively identified by Kew to H. paucinervia is Philippine Plant Inventory 19851, 15 May 1995, Camiguin, Timpoong Mountain.

Also, we can tentatively place here a photographic set in the web site PhytoImages [Luzon: Aurora prov., Baler, forest east of ASCOT campus; May 11, 2011, photographs of leaves, fruit and flowers, by P. Pelser and J. Barcelona.] If this is an accurate identification, then we can add  to the description of the species that the fruit is decidedly globose, about 1.5 cm or more across, the unopened flowers are white tinged with yellow at the apex.

Technical description: Merrill's description from 1920 based on Ramos, M. 34610.: "A glabrous tree, about 5 m high, the branches dark reddish-brown. Leaves coriaceous, oblong-elliptic, narrowed to the acute or somewhat decurrent base and to the obtuse or bluntly acuminate apex, 10 to 14 cm long, 4.5 to 6 cm wide; the margins distantly and rather coarsely toothed above or sometimes entire, the upper surface brownish-olivaceous, strongly shining, the lower surface dull, paler; lateral nerves abort 5 on each side of the midrib, prominent; petioles about 1 cm long. Racemes solitary, lateral, in the axils of fallen leaves, about 20 cm long. Flowers white, solitary or paired, 2 cm long, their pedicels 2 to 3 mm long, when in pairs free nearly to the base. Perianth lobes 4, the somewhat enlarged tips narrowly oblong, about 3 mm long and 1.2 mm wide. Hypogynous scales more or less united into a prominent white disk about 1 mm high."
