Emended description
Terrestrial, mycoheterotrophic herb. Inflorescence 10–25(–30) cm tall, solitary or branched at lower-half, purplish-white at flowering, black at fruiting, glabrous, ca. 0.8–1.5 mm in diam., with scale-like sheaths. Rhizome erect, J-shaped or complex, ligneous. Roots simple, radiate numerous, horizontally or downward elongate to 20–30 cm long, yellowish brown. Rachis 2–8 cm, 3–15 flowered, internode length of upper-half of rachis, 1–6(–10) mm. Floral bracts triangular, acute, 0.8–3.0 mm long. Pedicellate ovary ascending, 15–30 mm long. Flowers widely opening, ca. 2.5 cm in diameter. Sepals purplish white, linear, oblong-oblanceolate, ca. 12–17 mm long, 2.7–3.4 mm wide, apex obtuse. Petals purplish white, linear, oblong-oblanceolate, 13–17 mm long, 2.6–3.4 mm wide, apex obtuse. Lip shallowly spatulate, strongly 13–15 mm long, 4.0–4.5 mm wide in natural situation, ca. 6.0–7.0 mm wide when flattened, disc with rather scarce, long multicellular hairs which are rarely branched, near apex. Column 10–13 mm long, 1.2–2.8 mm wide slightly recurved, fused with lip about 1/2 its length, ventrally glabrous or slightly puberulent; anther white, ca. 1.5 mm wide. Capsule 15–30 mm long, black, cylindrical-fusiform, ascending at 70–90 degree angle from the axis. Flowering in mid-July to mid-September.
Note
When describing L. nigricans var. patipetala, Sawa (1980)[6] cited the specimens that he had collected from Ikku (Kochi Prefecture) on 5 August 1978. However, even though Sawa reported that the holotype specimen had been deposited in MBK and that the isotype specimens had been deposited in KYO and KOCH, no specimens fitting Sawa’s description could be located, despite intensive surveys of MBK, KYO and KOCH. The only putative original specimen that was found was a specimen in MBK that was collected by Sawa from Ikku (Kochi Prefecture) on 5 August 1979. This specimen has already been treated as an isotype by the MBK curator. The status of the specimen is somewhat controversial since both the collection date (5 August 1979 vs. 5 August 1978) and collection number (O-101 vs. O-135) differ from those of the L. nigricans var. patipetala protologue. However, the MBK specimen should still be recognised as an L. nigricans var. patipetala isotype, because the collection dates are similar enough that the difference could be regarded as a typing error. Actually, Hashimoto (1990)[2], who investigated the L. nigricans var. patipetala holotype when the specimen was still preserved in MBK, cited the collection date as 5 August 1979 and collection number O-101. Actually, the collection number O-101 was cited as a collection number for the Gastrodia pubilabiata holotype in the paper by Sawa (1980)[6] that described both L. nigricans var. patipetala and G. pubilabiata. It is highly possible that the collection number for L. nigricans var. patipetala and G. pubilabiata was somehow reversed in the protologue. Therefore, in order to stabilise the taxonomic status of L. nigricans var. patipetala, the MBK isotype was designated as the lectotype, according to Articles 9.11 and 9.12 of the ICN (McNeill et al. 2012).
