Spinulum lioui Li Bing Zhang & H.He View in CoL , sp. nov., Fig. 1 View FIGURE 1 .

Vernacular name: DZỄệaeƃffi.

Type:— CHINA: Heilongjiang: Xiaoxing’anling, Hongxing, Hongqi Experimental Forest Farm of Beijing Forestry College [48˚19 ʹ N, 129˚19 ʹ E], under Larix forest, 2 September 1963, T. N. Liou et al. 10407 ( holotype HIB-0099100!, isotype PE!).

Diagnosis: This new species is most similar to Spinulum canadense , but the former has trophophylls acicular and sporophylls with broad membranous transparent erose margins, while the latter has trophophylls narrow-lanceolate to narrow-ovate and sporophylls with very narrow membranous transparent erose margins.

Stolons slender and creeping, up to 1.4 m, green, with sparse trophophylls; lateral branches ascending, 8–17 cm tall, 1–3 times forked, sparse, whole branches terete, stem together with leaves 8–12 mm in diam. Trophophylls spirally arranged, dense, angled upward, acicular, 3–6 × 0.7–1.3 mm, leathery, without transparent hairs, midrib indistinct abaxially, visible adaxially, base cuneate, decurrent, sessile, margins entire, apex acuminate. Strobili solitary, terminal on branchlets, erect, terete, sessile, 2–3.3 cm × ca. 4 mm; sporophylls broadly ovate, ca. 3 × 2 mm, papery, with broad membranous transparent erose margins, apex acute. Sporangia enclosed.

Distribution and habitat:—Northeast China; forests, forest margins; ca. 1000 m.

Etymology:—In honor of the late Prof. Tchen-Ngo Liou ( ḾDZỄ 1898–1975), one of the founders of Chinese botany and one of the collectors of the type of this species.

Notes:— Lycopodium neopungens is a nom. nov. for L. pungens La Pylaie ex Iljin (1934: 117) , non Alderwerelt (1915: 26), based on the invalid name “ L. annotinum var. pungens La Pylaie ex Desvaux ” (1827: 182), with its type (not designated) from Europe. At species rank, L. canadense is the oldest name ( Haines 2003). Zhang & Iwatsuki (2013) also suspected that all these names represent the same species.

One duplicate of the type ( isotype) at PE, examined by LBZ in the 1990s, was not found by us.
