C. willmottiae Rehder & Wils. which has been quite widely cultivated, though not so much in Australia, is now included with C. sinensis. Plants offered in the trade as C. glabrescens Franch & Sav. (which has ovate sepals, flowers widely spaced on a hairless stalk and relatively small leaves to 8 cm long) may at least sometimes be C. spicata Siebold & Zucc.

C. sinensis var. calvescens Franch. & Sav. f. veitchiana (Bean) B.D. Morley & J.M.Chao is a form also well known to horticulture and once recognised as a species; it has red protruding stamens (distinguished from C. spicata by the leaves being hairless below).
