Notes relating to the Flora of Bhutan: XXII. Asparagaceae: Asparagus filicinus and Convallariaceae: Maianthemum oleraceum

Abstract

The variability of Asparagus filicinus Buch.-Ham. ex D. Don in the Sino-Hiamalayan region is discussed; the typical variety of this species has been generally misinterpreted. Three varieties are here treated and lectotypified: var. filicinus, var. giraldii C.H. Wright and var. lycopodineus Baker. The new combination Maianthemum oleraceum (Baker) Hook. f. & Thoms, ex Hook. f. var. acuminatum (Wang & Tang) Noltie is made.
