Description
TABLE 1. A comparison of Zingiber inodorum and three morphologically similar species.
| Zingiber inodorum | Z. guangxiense | Z. magang | Z. skornickovae | |
|---|---|---|---|---|
| Rhizome | each rhizome unit appearing in a lateral position in relation to its antecedent rhizome unit | rhizome units arranged in a single plane | each rhizome unit appearing in a lateral position in relation to its antecedent rhizome unit | unknown |
| Number of laminae per leafy shoot | 4–7(–9) | 11–20 | 3–5 | up to 13 |
| Petioles | 1.5–4 cm long | 1–10 mm long, and contain pulvinus only | 3–7.7(–10.5) cm long | up to ca. 3 cm long* |
| Ligules | 6–8 mm long, thinly coriaceous, densely villous (hairs yellowish) | 2–6 mm, membranaceous to papery, puberulous | 2–5 mm long, membranaceous to papery, glabrous or sparsely puberulous | 3–5 mm long, membranaceous, pubescent |
| Lamina shape | elliptic to obovate-elliptic | elliptic to narrowly ovate | broadly elliptic | obovate to ellipticobovate |
| Lamina size | 18–37 × 6–16.5 cm | 17–35 × 5–10 cm | (12.5–)19.5–26.5(–31.4) × (6.5–)8.5–13(–16) cm | 37–50.8 × 6.9–13.9 cm |
| Lamina surface and indumentum | prominently plicate, sparsely pubescent adaxially, densely pubescent abaxially | slightly plicate, glabrous adaxially, densely pubescent abaxially | slightly plicate, glabrous on both sides and shiny adaxially | prominently plicate, sparsely pubescent adaxially, pubescent abaxially |
| Colour of lamina (abaxially) | pale green | green tinged purple | pale green | pale green |
| Shape and width of bracts | narrowly ovate to narrowly oblong and rolling into a tube, 6–8 mm wide | narrowly ovate to narrowly oblong and rolling into a tube, 8–10 mm wide | convex and inflated at base, upper part nearly flat, do not roll into a tube, 10–19 mm wide | imbricate, with strongly undulating margins, 12–20 mm wide |
| Colour of bracts | white with purplish-red tinge | white with purplish-red tinge | yellowish green tinged red | cream-white at base, bright red to dark red towards apex |
| Shape and size of labella | narrowly ovate, 24–26 mm long, 5–6 mm at widest point | narrowly ovate to narrowly obovate, 26–28 mm long, 8–13 mm at widest point. | obovate, 23–25 mm long, 15–16 mm at widest point | broadly obovate, 28–34 mm long, 18–22 mm at widest point |
| Colour of labella | cream-white at base, the rest purple to purplish red, sometimes with cream striation near the throat of the flower | cream, sometimes tinged pink to purple at upper part | cream-white at base, dark purple to purple-violet in the centre, gradually changing to pale purple or almost white at upper margin | pale yellow at base, the remainder dark red-purple to purple-violet with small yellow or whitish blotches in the basal half of medial line, margin light yellow |
| Shape and size of lateral staminodes | ligulate and 10–12 × 2–3 mm | narrowly ovate and ca. 19 × 5 mm | obovate, 15–15.7 × 3–4.5 mm | obovate, 7–22 × 8–11 mm |
* Ligules were described as comprising of pulvinus only in protologue (Lý 2016), but Fig. 1 B in protologue shows that they are up to 3
cm long when including the attenuated bases of lamina.
