(Gramineae – Poinae) is the largest one of the non -Bambusoid grasses in Malesia. In 1994, I enumerated 38 native species and three varieties occurring in Sabah (3, 1 endemic), Celebes (3, 1 endemic), and New Guinea (37). The great number of species in New Guinea would suggest a southern origin, but molecular studies point at continental Chinese affinities with sections Homalopoa Dumort. (e.g. P. keysseri Pilg.) and Stenopoa Dumort. (P. papuana Stapf, perhaps P. crassicaulis Pilg.). (L.J. Gillespie, Ottawa, & R.J. Soreng, Washington, D.C., or. comm.). Thus far nothing had been seen from the Moluccas, where I expected the genus to occur on some high mountains with subalpine scrub- and grass vegetations for instance in Buru (G. Kapalat- mada, 2,700 m) or Ceram (e.g. G. Binaiya, 3,030 m). However, when in Edinburgh for the Tenth Flora Malesiana Symposium (July 2016) I discovered a collection by C.C.G. Argent from the G. Binaiya, which turned out to represent an undescribed species. This is one of a group of enigmatic Malesian species of Poa with only a single floret in the spikelet, whereby they cannot be identified with generic keys. The genus generally is regarded to have multi-flowered spikelets. One such species has therefore been described as an A ulacolepis Hack., non Ettingsh. MATERIALS AND METHODS The morphological data were entered into my DELTA file on the genus Poa from which a diagnose, most similar taxa, and description was generated. TAXONOMY The species seems most similar to Poa languidior Hitchc. from New Guinea. The identification key to differentiate between two species is presented. Poa opinata Veldk., spec. nov. — Type: Indonesia, Ceram, Manusela National Park, above Kanike village, G. Binaiya, 2,800 m alt., open situation at limestone ridge, 8 September 1987, Argent G. 87149A (holotype: E00772055; isotype: L, fragm.). Fig. 1. Perennials, branching extra-vaginally at base. Culms tufted, weak, 15‒40 cm long. Sheaths not articulating with the blades. Ligules unequal, the upper cauline longest, basal ligules collar-shaped, ca. 0.7 mm long, truncate, erose, the uppermost cauline ligules triangular, 0.7‒1 mm long, apex acute. Blades flaccid, erecto-patent, flat to V- shaped, 6‒7 cm × ca. 1 mm, smooth, acute. Panicle erect to secund, contracted, 5‒12 cm × 5‒15 mm, branches appressed to erecto-patent, smooth; lowermost ones solitary, 20‒55 mm long, naked in the lower 0.5-th, with 3‒5 spikelets. Spikelets 1- or 2-flowered, ca. 5 mm long, chasmogamous. mailto:jef.veldkamp@naturalis.nl REINWARDTIA 74 [VOL.16 Fig.1. Poa opinata Veldk. spec. nov.

Rachilla smooth, lowest internode 0‒1 mm long, process 1‒1.5 mm long, distinctly shorter than the upper glume. First lemma 3.6‒4 mm long, web absent, 3- or 5- nerved, midrib smooth or scaberulous, apex acute. First palea shorter than the lemma, keels smooth. Anthers n.v. Distribution. Endemic to Cer am. Etymology. “Opinatus” means “expected”, as the species forms a predictable stepping stone the occurrence of the genus between Borneo and Celebes on one side, and New Guinea on the other. Ecology. Open situation on limestone r idge, 2,800 m alt. Conservation status. Not known so far because only known from a single collection from a very remote place. Notes. Pr epar ing the descr iption was hamper ed by the unfortunate fact that the specimens had been glued to the herbarium sheet, whereby characters like ligules and even spikelet pubescence were difficult to observe. ACKNOWLEDGEMENTS The Keeper of the Herbarium of the Royal Bo- tanic Gardens (E) is very much thanked for the loan of the type specimen. L. J. Gillespie, Ottawa, & R. J. Soreng, Washington, D. C. are thanked for the fruitful discussions we had on the infra-generic taxonomy of Poa. REFERENCES http://data.rbge.org.uk/herb/E00772055 (accessed October 27, 2017) VELDKAMP, J.F. 1994. Poa L.
