Strobilanthes sunhangii T. Deng, J.T. Chen & Y.F. Deng, in Chen, Huang, Lv, Kuang, Luo, Y.-F. Deng et T. Deng. 2020. 双曲马蓝 || DOI: 10.3897/phytokeys.166.58831AbstractA new species of Acanthaceae, Strobilanthes sunhangii, is described from Mêdog County, Tibet, China. Morphologically, the new species is closely similar to S. medogensis and S. divaricata, but S. sunhangii differs in having glabrous stems, longer spikes, glabrous rachis, double curved corolla and glabrous calyx, different stamens and style.Keywords: Mêdog, morphological evidence, new species, Strobilanthes sunhangii Photograph of the holotype of Strobilanthes sunhangii T.

Deng, J.T. Chen & Y.F. Deng, sp. nov. Diagnosis: Strobilanthes sunhangii resembles S. medogensis, but differs by its stems subterete, glabrous (vs. slightly sulcate, bifariously puberulent); spikes (7–)11–22 cm long (vs. 3–6 cm long), rachis glabrous (vs. bifariously pubescent); corolla outside and lobes pinkish-white, inside purplish-pink (vs. corolla yellowish-white, but dull purple on lobes), the tube bent to ca. 90° twice (vs. straight), lobes apices emarginate (vs. rounded); calyx 7–8 mm long, glabrous, 5-lobed to middle (vs. ca. 12 mm long, gland-tipped pubescent, 5-lobed to base), lobes ovate, equal (vs. narrowly oblong-elliptic, subequal); stamens included (vs. exserted), filaments of shorter pair ca. 2 mm long (vs. 7–8 mm long), longer pair ca. 4 mm long (vs. 9–10 mm long), anther thecae ca. 4 mm (vs. ca.1 mm); style with sparse gland-tipped trichomes (vs. glabrous).Etymology: Strobilanthes sunhangii is named after Prof. Hang Sun (1963–) for his outstanding contributions to the flora of Himalayan regions and collecting this new species for the first time. Verucular name: The Chinese name is given as “双曲马蓝” (shuāng qū mǎ lán), referring to the double-curved corolla of the new species.

Australia's climate is changing rapidly due to rising global greenhouse gas emissions. Extreme weather events such as tropical cyclones, east coast low pressure systems, flash floods, droughts, bushfires, severe storms, and both land and marine heat waves are becoming increasingly common, as the National Climate Risk Assessment makes clear.
