Hind, D. (2004). Novaguinea (Compositae: Astereae: Lagenophrinae), a New Endemic Genus to Papua, Indonesia. Contributions to the Flora of Mount Jaya, XIII. Kew Bulletin, 59(2), 177-188. doi:10.2307/4115848

Distribution
New Guinea, Indonesian Papua.
Ecology
Wet and boggy subalpine grassland on limestone. Achene dispersal is proposed as raindrop dispersal.
Morphology General Habit
Dwarf, rosulate, clump-forming, perennial herb
Morphology Leaves
Leaves somewhat fleshy, pseudopetiolate, broadly ovate, indumentum very sparse above, scarcely moderately adpressed pubescent beneath, margins entire, apices acute to obtuse
Morphology Reproductive morphology Flowers Disc
Disc florets fewer than marginal, hermaphrodite, fertile, corollas 4-lobed, lobes ascending to spreading, apices acute to obtuse, margins thickened; anthers 4, appearing free, anther bases ecaudate, filaments attached near middle of corolla tube; style arms exserted
Morphology Reproductive morphology Flowers Florets
Marginal florets biseriate, female, corollas bilabiate and cryptically rayed, outer lobe broad and 2-lobed, inner lip linear and entire, corolla tube glandular-punctate at apex; style base lacking basal node, base and shaft glabrous, style arms exserted, short-papillose abaxially
Morphology Reproductive morphology Fruits
Achenes laterally compressed (ray) or trigonous (disc), body glabrous, short-beaked with thickened apical callus, sparsely glandular-punctate at base of beak; carpopodium procurrent on base of achene; pappus absent.
Morphology Reproductive morphology Inflorescences
Inflorescence of solitary terminal or subterminal capitula from centre of leaf rosette, sessile at anthesis, distinctly pedunculate post-anthesis and single-bracteolate, slightly inflated beneath involucre
Morphology Reproductive morphology Inflorescences Capitulum
Capitula cryptically radiate; involucre cupulate; phyllaries 2- or 3- seriate, outer larger than inner, apices obtuse to rounded; receptacle convex at anthesis, becoming conspicuously domed towards maturity
Note
Three collections from Mt Jaya represent the same taxon, clearly a member of the Astereae, and best placed in the subtribe Lagenophorinae Nesom. The affinities of Novaguinea within the subtribe Lagenophorinae In Novaguinea rudalliae the plants are tufted or turf-cushion-forming with apparently sessile, solitary capitula in the centre of a small rosette of leaves, eventually forming a short but stocky peduncle with a slightly inflated apex. The biseriate and distinctly bilabiate female marginal florets, outnumbering the conspicuous fertile disc florets, and the domed mature receptacle help to distinguish this genus within the subtribe. Novaguinea possesses several characters in common with Lagenocypsela, such as the rosulate habit, disciform capitula, flask-shaped, short-beaked epappose achenes, but differs in that the inner series of phyllaries in Novaguinea is shorter than the outer (the inner series are longer than the outer in Lagenocypsela), and its receptacles become domed (flat in Lagenocypsela). The female marginal florets are biseriate and distinctly bilabiate (few marginal florets with filiform corollas in Lagenocypsela), outnumbering the fertile hermaphrodite disc florets with uniform ovaries across the receptacle (male florets few and ovaries absent in Lagenocypsela). The achenes are sparsely glandular and laterally compressed, or sometimes trigonous, with a short beak and distinct apical callus (glabrous and lacking 'apical rim' in Lagenocypsela).
