... teretifolium A.R.Bean & Jessup sp. nov. affinis A. constablei autem stipulis brevioribus, fructibus longioribus, floribus pro parte maxima 4- meris, petalis brevioribus differt. Typus: Queensland. L EICHHARDT D ISTRICT : Lonesome National Park, NNE of Injune, 6 May 1999, A.R.Bean 14832 (holo: BRI; iso: AD, K, MEL, MO, NSW, PERTH, distribuendi) Apatophyllum sp. (Expedition Range E.J. Thompson AQ440723) in Henderson (1997). Densely branched rounded shrub 25–40 cm high, glabrous. Leaves sessile, opposite to sub- opposite or occasionally alternate, linear, (6–) 8–12 × 0.3–0.5 mm, elliptical in cross-section; venation obscure, longitudinal; apex acute to acuminate, pungent-pointed. Stipules linear, 0.9–1.5 mm long, brown, persistent, mostly broad-based and with 2 or 3 short lateral lobes; apex acute to acuminate. Inflorescence axillary, reduced to a single flower, with 1 or sometimes 2 pairs of empty pherophylls shortly distal to the base of the axis. Anthopodia 1.7–2.5 mm long. Pherophylls cymbiform, 0.9–1.5 mm long, apex acute, margins denticulate. Perianth 4 or 5-merous. Sepals deltate, 0.6–0.7 mm long, persistent on mature capsule; apex acuminate, margins denticulate. Petals deltate, 0.9–1.2 mm long, 0.7–0.9 mm wide at base, white, somewhat persistent beyond anthesis; apex acute, margins entire. Stamens 4 or 5, equal in number to petals, inserted on margin of disc; filaments tapering, 0.4–0.5 mm long, somewhat persistent beyond anthesis; anthers basifixed, 0.3–0.4 mm long and c. 0.4 mm across. Disc fleshy, shallowly cupular. Ovary ovoid, 2-locular, almost completely immersed in disc; ovules 2 per loculus. Style 0.6–0.7 mm long. Capsule compressed obovoid, 2-valved, 5.2–6 × 2.0– 2.8 mm, surface smooth or minutely papillose. Seeds ellipsoidal, c. 3.2 mm long, c. 1.4 mm in diameter; testa dark brown, smooth but with fine transverse markings; aril white, clasping base of seed. Fig. 1, 3C. Distribution and habitat: A. teretifolium is known from 3 localities; the Expedition Range, Lonesome National Park, and the Barakula State Forest near Chinchilla (Map 1). It grows in Eucalyptus dominated woodland to low open woodland with a heathy understorey, on shallow sandy soils. Phenology: Flowers and fruits are recorded for March and May. Notes: A large proportion of seeds are evidently destroyed by caterpillars. Insect predation is likely to be a limiting factor for regeneration of this species. A. teretifolium differs from A. constablei by the shorter stipules, longer fruits, the predominantly 4-merous flowers and the shorter petals. Conservation status: Three populations of A. teretifolium have been recorded. Applying the IUCN guidelines (Anon. 1994), a category of ‘vulnerable’ is proposed (Criterion D2). Etymology: From the Latin teretifolius , meaning ‘with terete leaves’.
