Based on the similarity of external appearance, Zanchiophylus may be related to Tuponia Reuter, 1875 (Wagner, 1975; Zheng and Li, 1992), but that genus lacks the flabellate pulvillus and broadened, strongly wound vesica.
45 x 28 mm (excluding the petals), flabellate, pulvinate, 2 to 3-flowered, inspicuously stipitate; floral bracts those of the branches narrowly ovate, obtuse and minutely apiculate, rigid at base and thin in texture toward the apex, stramineous, nerved, entire, densely and conspicuously white-farinose-lepidote, trichomes concealing its color, about equaling to slightly exceeding the sepals, carinate, cymbiform, 37-42 x 16-20 mm, those of the simple part of the inflorescence resembling the primary bracts but suboblong and slightly dilated at its apical half, apex distinctly emarginated and minutely apiculate, distinctly exceeding the sepals and concealing the flowers except for the petals, ca.

Ovules solitary or occasionally paired in the axils of bracts on short branchlets or stalks which themselves are axillary on the first-, second- or occasionally third-year branchlet, sessile, subtending scales about 12-20, decussate, ovate to flabellate, concave, membranous, often rugose, nearly enclosed at maturity by the aril; arils open at the apex, 5-10 x 5-7 mm, green when young, sometimes remaining so, becoming orange or usually bright scarlet red at maturity; seeds hard, ovoid, 5-7 x 4-5 mm, becoming 2-4-angled at the apex, the hilum slightly depressed, ovate, triangular or square.
