AF31DDC47DA2530DA2AFAAA5AAEF0572.taxon	diagnosis	Diagnosis. Sinojohnstonia henanensis is morphologically similar to S. chekiangensis and S. ruhuaii but differs from the former in its basal leaves with petioles 1 – 11 cm, lamina 0.7 – 6 × 0.6 – 4 cm (vs. with petioles 10 – 18 cm, lamina 3 – 12 × 1.5 – 9 cm), calyx in flower ca. 2.5 – 3.5 × 0.5 – 1.2 mm, obviously shorter than corolla tube (vs. in flower ca. 3 – 7 × 1.4 – 2.7 mm, slightly longer than corolla tube), corolla blue-purple, slightly pinkish white, ca. 6 – 10 mm, lobes ca. 1.8 – 2.5 mm (vs. white or light reddish, ca. 10 mm, lobes ca. 3 – 4 mm), and style ca. 6 – 8 mm (vs. ca. 3 – 6 mm), and from the latter in its calyx in flower obviously shorter than corolla tube (vs. in flower slightly longer than corolla tube), corolla blue-purple, slightly pinkish white, ca. 6 – 10 mm (vs. white or light reddish white, ca. 5 – 6 mm), anthers exserted from the corolla tube, upon the throat appendages, filaments ca. 2 – 4 mm (vs. anthers exserted somewhat from the corolla tube, but below the throat appendages, filaments ca. 0.5 mm), and style ca. 6 – 8 mm (vs. ca. 2.5 – 4 mm). Their differences are summarized in Table 1.	en	Jiang, Li-Qiong, Luo, Yuan, Gong, Jian-Ping, Zhang, Nai-Yu, Li, Pan, Liao, Wen-Bo, Liu, Lu-Xian (2025): Sinojohnstonia henanensis (Boraginaceae), a new species from Henan, China.
