BA320FC1C9216D041732F3C8D67946B0.taxon	diagnosis	Diagnosis. This species is most similar to the Medinilla pendula species complex in its whorled leaves, 4 - merous flowers, and pendulous inflorescences. It differs, however, in its secondary veins of leaves being distinct only on the adaxial surface, cauline or axillary inflorescences, and straight anthers.	en	Fernando, Edwino S., Quakenbush, J.

Flowers 4 - merous, petal 8 x 4 mm, oblique-oblong, often reflexed, orange-red, red, or pink; stamens 8, usually positioned above the style, anthers linear-lanceolate, 2.5 - 4 mm long, rather straight, purple, with a yellow dorsal spur of 0.6 mm long on the connective and a pair of partly joined stout, ventral appendages at the base of the anther sac; filament 4 mm long, pale white; style terete, 10 mm long, pale white; hypanthium campanulate, the rim generally truncate or sometimes very shallowly lobed, pale or light green, 3 - 4 x 3 - 4 mm; pedicel pale pink or red, about 7 mm long. Fruit a subglobose berry, 4 - 6 x 5 - 7 mm, light green when young and with bright red calyx rim, entirely purplish-black when ripe; the peduncle and pedicels red. Seeds numerous, embedded in pulpy tissue, ovoid, 1 - 1.5 x 0.5 - 1 mm, chestnut brown. Seedling with epigeal germination, phanerocotylar, cotyledons foliaceus, 2 - 3 x 2 mm, broadly ovate, apex rounded or obtuse, sometimes shallowly emarginate; eophylls simple, opposite, broadly elliptic-ovate to orbicular, 3 - 7 x 3 - 5 mm.	en	Fernando, Edwino S., Quakenbush, J.

Cultivated: Luzon Island, Laguna Province, Municipality of Los Banos, seedlings grown from seeds of Fernando 3831 germinated in nursery, 4 May 2016, Fernando 3831 A (LBC). Some photos of Leonard L. Co from Mt Hamiguitan taken in January 2005 and appearing in PhytoImages (www. phytoimages. siu. edu) with five of these identified as Medinilla surigaoensis (DOL nos. 27282 - 27284, 27439, and 27534) and several others as Medinilla sp. (DOL nos. 27278 - 27281 and 27533) (Pelser et al. 2011) belong to this new species. Unfortunately, we have been unable to find at PUH, where Mr Co was based, the specimens or his field notes associated with the photos. The vouchers are likely among approximately 6,000 unprocessed specimens still wrapped in about 200 plastic bags.	en	Fernando, Edwino S., Quakenbush, J. Peter, Lillo, Edgardo P., Ong, Perry S.

BA320FC1C9216D041732F3C8D67946B0.taxon	distribution	Distribution. Thus far, this new species is known only from Mt Redondo on Dinagat Island and Mt Hamiguitan in the Pujada Peninsula on Mindanao Island, Philippines. Dinagat Island, Surigao del Norte Province, and the Pujada Peninsula form part of the same belt of the Eastern Philippine Cretaceous ophiolite and ophiolite complexes (Balce et al. 1976; Yumul et al. 2003, 2008; Tamayo et al. 2004) that are now large areas of ultramafic landscapes with metallic ore deposits (e. g., iron, nickel, chromium) and hosting a unique type of forest formation (Fernando et al. 2008).	en	Fernando, Edwino S., Quakenbush, J.

Lim, former Director of the Biodiversity Management Bureau, Department of Environment and Natural Resources of the Philippines, and now Executive Director of the ASEAN Centre for Biodiversity, whose dedication and commitment to protecting Philippine biodiversity is admirable. Director Lim has also been active in the international biodiversity conservation sector.	en	Fernando, Edwino S., Quakenbush, J. Peter, Lillo, Edgardo P., Ong, Perry S.
