Scientific name: Paspalum batianoffii

Paspalum batianoffii was a perennial grass with horizontal stems (or runners). The stems were 20–40 cm long with two or three nodes. The lateral branches were sparse and the stem was enclosed by the base of the leaves. The leaf-blades were flat or rolled, 8–16 cm long and 2–4 mm wide. Both the surface of the leaf and the margins were smooth. The leaf bases were hairy and covered in warty bumps. The main leaf vein was narrowly winged, flattened and 2 mm wide. The flower-head was composed of two or three elongated spikes 6–9 cm long. The central flower-head axis was 1.5–2.5 cm long. The spikelets (small flower spikes) were solitary and the fertile spikelets had smooth stalks about 0.5 mm long. The fertile spikelets comprised one small sterile flower at the base, and one fertile flower. The sterile flowers had no modified leaves enclosing them. The fertile flowers were enclosed by a glume (modified leaf immediately below the flower-head). The upper glume was elliptic in shape, approximately 5 mm long, leathery in texture, with two veins. The lower glumes were absent or obscure. There were three anthers (pollen producing part of plant), each 2 mm long (Clayton et al. 2006).

The type specimen of Paspalum batianoffii was collected from the Port Curtis district at Statue Bay, 6.5 km south-east of Yeppoon, Central Queensland (Simon 1992a).

Paspalum batianoffii is only known to have occupied a narrow foredune with open woodland of Casuarina spp., Hibiscus spp. and Excoecaria ssp. and groundcover of Guinea Grass (Panicum maximum), Railroad Vine (Ipomoea pes-caprae) and Prickly Couch (Zoysia macrantha). The species performed a sand binding function just above high watermark (Simon 1992a).

The reasons for the decline and extinction of Paspalum batianoffii are unknown.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
