The species is a medium-sized tree with tall buttresses.[2] Leaves are variable in shape (particularly in cordate base), papery with a pale and dull undersurface, laminar service highly variable in lustrousness, the margin may be revolute (rolled towards lower surface), variable size, some 10-28 x 3.5-10 cm. Panicles (the branched inflorescence), bracts (specialised leaves), stipules and parts of the petals that are exposed in the buds, are all covered in dense persistent buff-coloured hairs (Trichomes). There are 15 stamens in three subequal verticils (whorls), they are shorter than the style. The panicle is up to 9 cm long, can be arranged 3-axillary or be terminal, one branch. The ovary is small and tapers to a distinct subcylindrical stylopodium, equally long, and short style.
It is distinguished from other MalesianHopea species by the following traits: evenly pubescent (hairy) young parts; lower part of the leaf is smooth (glabrous) and when dry is dull greyish.[3]
Surrounding the village of Kwerba, in the Foja Mountains, West Papua, is a species-rich rainforest.[4] The forest is not tall, even emergents are only some 25m tall, this in line with many forests of New Guinea, but is unusual for rainforests elsewhere in the world. Hopea novoguineensis is one of the most abundant trees, usually in the second-highest stratum of the canopy, but occasionally an emergent.
The species was described by Dirk Fok van Slooten (nl) (1891-1953), a Nederlanders botanist, in 1924 in the periodical Nova Guinea; a Journal of Botany, Zoology, Anthropology, Ethnography, Geology and Palaeontology of the Papuan Region. Leiden.[9]
