Bishopanthus

Shrubs to 0.5 m tall, moderately to multi branched; stems with latex, pale reddish, internodes short, jointed, densely white-wooly strongly invested by leaf bases. Leaves opposite, bases strongly vaginate, vagination usually ca. 5 mm long, longer than the internode, imbricate parts of vaginate bases wooly-tomentose externally; petioles short, ca. 0.5 mm long; blades oblong-ovate, mostly 2–4 cm long and 8–16 mm wide, base rounded, margins with many distinct small teeth, apex shortly acute, sub-longitudinally trinervate from near base, upper surface bullate with bulging areoles, major nerves sunken and diffusely arachnoid-tomentose, undersurface densely, grayish-wooly tomentose, major veins raised. Inflorescence abruptly terminal on leafy branches. Heads solitary, over-topped by lateral branches, ca. 10 mm high, ca. 12 mm wide, excluding rays; involucral bracts subequal, ca. 25, in ca. 2 series, oblong-lanceolate, 7–8 mm long and ca. 1.5 mm wide, outer bracts with apices reflexed, outer surface distally green, subglabrous, below densely white wooly-tomentose, inner bracts not reflexed distally, acute, subglabrous. Ray flowers ca. 20, female; corollas yellow, basal tube 2.5–3.5 mm long, narrowly funnelform with sparse spreading trichomes; limbs linear, 11–12 mm long, to 2 mm wide, apices tridentate, basally with minute, short biseriate trichomes, distally rather densely arachnoid-tomentose and gland-dotted. Disc flowers ca. 25, bisexual; corollas yellow, 7.0–7.5 mm long, basal tube ca. 2.5 mm long, hirtellous with sparse straight-spreading trichomes, trichomes with one row of cells, throat ca. 2.5 mm long, subcylindrical, below with few short biseriate trichomes and fewer uniseriate trichomes, distally with almost no trichomes and sparsely gland-dotted, lobes linear, ca. 2.8 mm long and 0.5 mm wide, near margins distally with few stomata and many glandular dots, rather densely arachnoid-tomentose. Anther filament collars ca. 0.25 mm long, with cells shortly oblong, cell walls firm, in-ornate; thecae ca. 2.5 mm long, endothecial cells obscure, somewhat oblong, shields tenuously irregularly areolate; apical appendage oblong-ovate, ca. 0.4–0.5 mm long, 0.22 mm wide, glabrous. Style base with distinct expanded node, hispidulous upper part of style shaft ca. 3 mm long; branches ca. 1 mm long. Achenes ca. 2.7 mm long, 8–10-ribbed, with short trichomes, setulae and glands, setulae numerous, contorted, distally on achenes longer, trichomes very sparse, with single row of cells, glands, sparse, short-stipitate, with minute capitula; carpopodia shortly stopper-shaped, sub-annuliform, ca. 0.35 mm wide, 0.15 mm high; with cells in 12–15 series, 12–15 μm in diameter, with thickened walls. Pappus setae densely congested, larger setae ca. 35, sometimes irregularly elongate, mostly 4.5–6.0 mm long, apices tenuous, outer series of setae shorter, narrower, mostly 0.7–1.0 mm long, scabrous, simple. Pollen ca. 37μm in diameter, irregularly spinulose.
