Bracts 2, narrowly lanceolate to linear-lanceolate, 6–9.5 cm long, apex acuminate, 1 - flowered. Flowers faintly fragrant, 6–6.5 cm in diam.; pedicel 2–3 cm long; perianth tube ca. 0.5 cm long; sepals spreading, oblanceolate, ca. 3.5 cm × 7–10 mm, limb apex bluish purple, claw yellowish green; petals erect, oblanceolate, 2.8–3.1 cm × 5–7 mm, upper part bluish purple, lower part brown, densely spotted; stamens 2.2–2.4 cm long; anthers bright yellow, 1.4–1.6 cm long, filaments flattened; style branches arched, margins membranous, ca. 3 cm × 5 mm, apex lobes triangular, ca. 5 × 3 mm; stigmatic lip bilobed; ovary trigonous, ca. 3.6 cm long, ca. 4 mm in diam., with a neck 2.3–3.5 cm long.

Flowering May – June, fruiting July – September.</p><p>Distribution and ecology.</p><p>I. helanshanensis is distributed in the Helan Mountains and Luo Mountains (Inner Mongolia Autonomous Region and Ningxia Hui Autonomous Region, China), where it grows in open grassy slopes or forest edges (Fig. 6).</p><p>Etymology.</p><p>The type locality is situated in the Helan Mountains, hence the specific epithet “ helanshanensis ” is chosen.</p><p>Preliminary conservation status.</p><p>Based on the IUCN (2024) Red List Categories and Criteria (Version 3.1, 2012), I. helanshanensis is preliminarily assessed as Vulnerable (VU). This assessment is based on its simultaneous fulfilment of the following 2 criteria: D 1 (total number of mature individuals estimated to be fewer than 1,000) and D 2 (Area of Occupancy is estimated to be less than 20 km 2, coupled with a very limited number of locations). Plausible future threats include habitat degradation and fragmentation resulting from ongoing tourism development, such as trail construction, visitor foot traffic, and associated infrastructure expansion, which may negatively impact the long-term survival of this taxon. It is strongly recommended that systematic field surveys be conducted promptly to verify its distribution range, population dynamics, and specific threats, thereby providing a scientific basis for confirming its final conservation status.</p><p>Notes.</p><p>The distribution of this species in the Luo Mountains, at the border between Hongsibu District and Tongxin County in Wuzhong City, Ningxia Hui Autonomous Region, is only documented through a single herbarium specimen (BNU 0019183). Since the Luo Mountains has been designated as a national nature reserve, further verification is required to assess the species’ population status within this region.</p><p>Other specimens examined.</p><p>1.
