Sunyatseni, monogr. ser. 1:154. 1981, nom. invalid. [Description] Tree 3 m tall; branchlets at first greyish-white pilose, soon glabrous. Leavescoriaceous, elliptic, 6-8. 5 cm long, 2-3 cm wide, apices acuminate or caudate with a 1-1.5 cm long cauda, bases broadly cuneate or obtuse; greyish-brown above in the dry state, not shiny, midvein brown-puberulent; base of the midvein pilose below; lateral veins7-9 pairs, equally conspicuous on both surfaces; upper half of margins serrulate; petioles 3-4 mm long, hirtellous. Flowers terminal; pedicels 5 mm long, thick; bracts 5-6, 3 on the middle of the pedicel, crescent-shaped, glabrous, margins thinlymembranous, 1-2. 5 mm long; 2-3 bracts relatively large, born near the sepals; calyxshallowly cup-shaped, 5-6 mm long, glabrous, sepals semiorbicular，margins thin; petals white, 6-7, outer 2 somewhat brownish-pubescent, 1. 5 cm long, the remainingpetals 2 cm long glabrous; stamen length ca. equal that of petals, outer filament whorlbasally connate into a tube; free filaments shorter, glabrous; ovaries glabrous; stylelength equal to stamens, shallowly 3-cleft. Capsules elliptic-ovate, 2. 5 cm long, 1. 5 cmwide, 3-locular or 1-locular, 1 seed per locule; valves woody, 1.5-2 mm thick. This species is close to C. tsaii var. synaptica only the calyx is much longer and notciliate, and the fruit is longer. The species differs from C. cuspidata by having pubescentbranches, filaments connate into a short tube and fruit longer.
