Zhang BLSC-24072803 (IBSC).</p><p>Ecology &amp; Phenology:— Zingiber bambusifolium subsp. bambusifolium grows in understories of carbonate rock-based (limestone or dolomite) soil. Rhizomes are often covered by thick litter layers. The elevation of occurrence is between 699 m to 2000 m. Flower records are from late-July to late August. Fruits start to mature from September but last till early November.</p><p>Distribution &amp; Conservation status:— Zingiber bambusifolium subsp. bambusifolium is currently known from Baise City and Hechi City in Guangxi Province and Qiannan Buyi &amp; Miao Autonomous Prefecture of Guizhou Province (Fig. 5). The Extent of Occurrence (EOO) is about 11500 km 2. In the two spots I collected the subspecies in Leye County in Guangxi Province and Guiding County in Guizhou Province, the species forms rather large populations. At present, I therefore propose to treat Z. bambusifolium subsp. bambusifolium as ‘Least concerned’ (LC) according to the latest IUCN Criteria (IUCN 2012, 2019).</p><p>Etymology:— The specific epithet “ bambusifolium ” is derived from the narrow laminae that resemble bamboo leaves.</p><p>Notes:— The presence of minute, circular or oblong, dark brown punctae on upper surface of laminae on type specimens of T. bambusifolia var. bambusifolia is a critical character in resolving its identity. These punctae appear to be natural pigmentation. They are visible with the naked eye on dry specimens (see Fig. 1D &amp; 2B). They also occur on several other species of Z. sect. Cryptanthium that have a burgundy red tinge (when fresh) on the lower surface of their laminae, e.g. Z. cochleariforme Fang (1980: 225), Z. guangxiense Fang (1980: 226) (unpublished data). These punctae do not show on a light microscope leaf epidermis examination after regular pretreatment of removing mesophyll cells. Nor do they show under scanning electron microscope (SEM) either. Coincidentally, Léveillé (1906) named T. bambusifolia var. rubromaculosa (rubro+ maculosus, meaning red spotted or red blotched), after the irregular, diffused brownish patches (“Feuilles tachées de rouge”) that appear on the lamina of the type specimens (Fig. 1B). However, those patches are not punctae; they are probably caused by fungi.</p><p>During the search for Z. bambusifolium subsp. bambusifolium from its type locality, three other species of Z. sect. Cryptanthium, viz. Z. atrorubens, Z. emeiense Zhu (1984:185), and Z. tuanjuum Zhu (1984:187), were found in the general area. They all differ from Z. bambusifolium subsp. bambusifolium by their lack of the minute, circular or oblong, dark brown punctae on upper surface of lamina on dry specimens. Zingiber atrorubens (= T. bambusifolia var. rubromaculosa) futher differs from Z. bambusifolium subsp. bambusifolium by the labellum being pink to violet with white striae (vs cream-coloured), lateral staminodes being absent or vestigial (vs lateral staminodes prominent) and leaf sheaths being partially closed (vs open). Zingiber tuanjuum futher differs from Z. bambusifolium subsp. bambusifolium by having longer ligules (10–30 mm vs 1–6 mm), larger laminae (30–41 × 3.4–6.5 vs 14–27 × 1.8–3.5 cm) and larger bracts (2.5–5.7 × 1.2–3.5 cm vs 2.5–4.5 × 0.6–1.4 cm) that are densely imbricated (vs loosely arranged). Zingiber emeiense futher differs from Z. bambusifolium subsp. bambusifolium by its running rhizome with the vegetative rhizome units having a pseudo-neck that is 12–19 cm long (vs rhizome compact and pseudo-neck absent), longer ligules (7–9(–13) mm vs 1–6 mm), longer petioles (3–40 mm vs 1–5 mm), labella and lateral staminodes being deep violet with white striae (vs cream) and the latter connating to the former at basal 1/5 to 1/2 (vs 2/3–4/5).</p></div>	https://treatment.plazi.org/id/03F5BF6AFFB3FFE4FF2DFA9DF77114B9	Public Domain	No known copyright restrictions apply.

Bai BLSC-24082201 (IBSC) .</p><p>Ecology &amp; Phenology:— Zingiber bambusifolium subsp. magenteum grows in understories of limestone hills. Rhizomes are often covered by thick litter layers. The elevation of occurrence is between 970 m to 1500 m. Flowering commences from mid-August and probably extends to late September. Fruits start to mature from October but last till late November.</p><p>Distribution &amp; Conservation status:— Zingiber bambusifolium subsp. magenteum is currently known from Xingren County and Xingyi City of Qianxinan Buyei and Miao Autonomous Prefecture, Guizhou Province and Wenshan Zhuang Autonomous Prefecture, Yunnan Province in southwestern China (Fig. 5). The Extent of occurrence (EOO) is about 7400 km 2. In the three spots I collected the subspecies, it forms rather large populations. The subspecies is not known to be harvested as medicine or vegetables.At present, I therefore propose to treat Z. bambusifolium subsp. magenteum as ‘Least concerned’ (LC) according to the latest IUCN Criteria (IUCN 2012, 2019).</p><p>Affinities:— Apart from the typical subspecies, Z. bambusifolium subsp. magenteum is also superficially similar to Z. tenuifolium Bai et al. (2015: 92) . Zingiber tenuifolium is so far only known from a few populations in Xinping County, Yuxi City, Yunnan Province, about 200 km west of the nearest occurrence of Z. bambusifolium subsp. magenteum (see Fig. 5). It grows in sandstone and shale-derived substrates along creek in an elevation of 500– 700 m. Zingiber bambusifolium subsp. magenteum differs from Z. tenuifolium by broader lamina (3–5 cm), corolla lobes cream to yellow with red tinge, lateral staminodes connate to labellum at basal 2/3–4/5 and vegetative rhizome units sometimes much elongated (pseudo neck 1–10 cm long). In Z. tenuifolium, laminae are 1.5–3 cm wide, corolla lobes are reddish brown, lateral staminodes connate to labellum at basal 1/3–1/2, vegetative rhizome units never elongated (lacking a pseudo-neck). Although the differences seem to be subtle, unpublished phylogenetic study shows that the two entities are not especially closely related.</p><p>Etymology:— The subspecies epithet magenteus (meaning red-purple (Stearn 1992)) refers to the purple-red labellum and lateral staminodes.</p><p>Notes: Zingiber bambusifolium subsp. magenteum seems to hybridize with Z. densissimum Tong &amp; Xia (1987: 467) . Putative hybrid individuals (L. Bai BLSC- 24082102 &amp; L. Bai BLSC- 24082202) are seen in the two populations of Z. bambusifolium subsp. magenteum from Wenshan Zhuang Autonomous Prefecture in Yunnan. Although Z. densissimum is not seen in the same localities, they do occur in the general area of Wenshan Zhuang Autonomous Prefecture. Zingiber tenuifolium was also suspected to hybrid with Z. densissimum (Bai et al. 2024) .</p></div>	https://treatment.plazi.org/id/03F5BF6AFFBFFFE7FF2DFDC3F68F14F0	Public Domain	No known copyright restrictions apply.
