Summary

Lasjia griseifolia Utteridge & Brambach, a member of the Proteaceae, is described and illustrated as a new species from the Indonesian island of Sulawesi. The new species is similar to L. erecta, also from Sulawesi, and morphological differences between the taxa are discussed; a line illustration and detailed notes on the conservation status are provided.

 

Key Words: Macadamia, Malesia, Proteales, ultramafic, Wallacea

A habit, note the number of leaves per whorl and the grey adaxial surface; B abaxial leaf surface, note the persistent ginger-brown matted hairs; C, D axillary conflorescences and creamy-white perianth.

RECOGNITION. Recognised in the genus Lasjia by the combination of the following characters: indumentum of persistent simple matted hairs throughout the plant (on the hardened stems, mature leaves, inflorescence axes, pedicels and abaxial tepal surfaces) and the very short pedicels less than 3.5 mm long; in addition, the new species usually has whorls of 5 leaves, obovate to elliptic laminas and a retuse to emarginate apex, and erect inflorescences to 6 cm long.

ETYMOLOGY. Named for the grey leaves in the field.

[Botany • 2014] Banksia vincentia • Could this be Australia’s Rarest Banksia (Proteaceae)?, A New Species Known from Fourteen Plants from south-eastern New South Wales, Australia

Abstract

Possession of hooked, distinctively discolorous styles, a broadly flabellate common bract subtending each flower pair, and a lignotuber place a putative new species, Banksia sp. Jervis Bay, in the B. spinulosa complex. Phenetic analysis of individuals from all named taxa in the B. spinulosa complex, including B. sp. Jervis Bay, based on leaf, floral, seed and bract characters support recognition of this species, which is described here as Banksia vincentia M.L.Stimpson & P.H.Weston. Known only from fourteen individuals, B. vincentia is distinguished by its semi-prostrate habit, with basally prostrate, distally ascending branches from the lignotuber, and distinctive perianth colouring. Its geographical location and ecological niche also separate it from its most similar congeners.

Keywords: Basipetally, Putative, discolorous, distally, ascending

Banksia vincentia Stimpson & P.H.Weston sp. nov.
With affinities to Banksia spinulosa sensu lato, differing from other taxa in the complex by a much lower stature with stems basally prostrate from lignotuber, distally ascending.

Distribution:— Banksia vincentia is restricted to a small area near Vincentia on the south coast of New South Wales.

Derivation of Epithet:— The specific epithet is a noun in apposition that refers to the named place nearest to the only known location of this species.
