DARWIN, S. P. (2010). A taxonomic revision of Timonius subgen. Pseudobobea (Valeton) S. P. Darwin (Rubiaceae). Candollea 65: 217-240. In English, English and French abstracts.
Twenty-one species, distributed from Sulawesi (Indonesia) to Rossel Island (Louisiade Archipelago) through the Moluccas (Indonesia) and Papua New Guinea, are assigned to Timonius subgen. Pseudobobea (Valeton) S. P. Darwin, a new taxon based on Timonius sect. Pseudobobea Valeton (Rubiaceae, Guettardeae). Nine new species are described: Timonius akunensis S. P. Darwin, Timonius bracteoides S. P. Darwin, Timonius carrii S. P. Darwin, Timonius clathratus S. P. Darwin, Timonius leptocalyx S. P. Darwin, Timonius moluccanus S. P. Darwin, Timonius reflexus S. P. Darwin, Timonius repertus S. P. Darwin, and Timonius rosselensis S. P. Darwin. Species of the new sub-genus are distinctive in having usually vertically oriented fruit pyrenes, reflexed calyx lobes, and leaf blades with corivate venation. Lectotypes are designed for the names Timonius argenteus Valeton, Timonius merokensis Wernham, Timonius minahassae Koord., Timonius papuanus Mern, Timonius schefferi Valeton, Timonius schumannii Koord., and Timonius versteegii Valeton. Neotypes are designated for the names Timonius branderhorshi Valeton, and Timonius grandifolius Valeton. A taxonomic key to all species is provided as well as information on their ecology and distribution.
