conservation
Conservation status in China: — Phlomoides zenaidae is restricted to one locality in Nilka County, Xinjiang province. In total, approximately 1,000 individuals were found in a semiarid desert grassland. This species maybe easily threatened by habitat lose. Thus P. zenaidae should be classified as Vulnerable (VU: D 1) based on the IUCN Red List Categories and Criteria (IUCN 2019).
description
Perennial herbs, 40 – 60 cm tall. Roots linear-tuberous. Stems erect, subquadrangular, purple, 1 – 3 branched, glabrous. Basal leaves with petioles 4 – 6 cm long, white, margin white pilose; lamina oblong, margin coarsely crenate, thick papery, 10 × 3 – 4 cm, adaxially green, glabrous, abaxially light green, with sparse, simple and stellate pilose hairs; stem leaves opposite, similar to basal leaves; petioles short, 0.5 – 1 cm long. Verticillasters 6 – 10 flowered, distant; floral leaves sessile, rhombus-oblong, subglabrous, margin remotely dentate, shorter than verticillasters, gradually reduced upward; bracts ovate-lanceolate, 6 – 8 mm long, glabrous, margin sparsely ciliate. Calyx tubular-campanulate, ca. 18 mm long, glabrous outside, teeth subequal, 1.5 – 2 mm long, apical emarginate, with spines 1 – 1.5 mm long, tufted hairy inside. Corolla purple, ca. 3.5 cm long, 2 - lipped; upper lip ca. 15 mm long, galeate, densely stellate tomentose outside, margin entire, glabrous inside, margin ciliate; lower lip 3 - lobed, ca. 20 mm long, flabellate, middle lobe largest, oblong, lateral lobes ovate; tube slender, ca. 18 mm long, annulate pilose inside near base. Stamens 4, included, glabrous, posterior filaments with upwardly curved appendages at base. Style included, apex unequally 2 - lobbed. Mericarps elliptic, glabrous (Fig. 1).
discussion
Taxonomic notes: — Morphologically, Phlomoides zenaidae is obviously different from other Chinese species by posterior lip being glabrous inside with an entire margin (vs. posterior lip bearded inside with a denticulate margin).
distribution
Distribution, habitat and ecology: — China and Kazakhstan; new record for China, occurring in Nilka County, Xinjiang province. It grows on arid gravel hillsides, 1100 – 1200 m, together with other species, such as Ixiolirion songaricum Ping Yan (1996: 605), Scutellaria przewalskii Juzepczuk (1951: 400), Ziziphora tenuior Linnaeus (1753: 21), etc. (Fig. 2).
etymology
