Rubus lasiostylus var. glabratus (Focke) Chand.Gupta & S.S.Dash , stat. nov.

Basionym. Rubus lasiostylus forma glabratus Focke in Hooker’s Icon.: pl. 20 (ser. 3, 10) (1891) t. 1951 (as ‘forma glabrata ’).

Type. Augustine Henry 5788 C (lectotype designated here: GH barcode 00040646*,https://s3.amazonaws.com/huhwebimages/ A868 B955383 D4 A3 / type/full/40646.jpg; accessed on 22 Apr. 2017; isolectotypes CAL), China, Hupeh [Hubei]. — Fig. 2c .

Diagnostic characters — Branches, petioles, pedicels and abaxial surface of calyx glabrous. Leaves 3–5-foliolate. Stipules and bracts ovate-lanceolate. Bracts up to 15 mm long.

Distribution — Known only from China (Hubei, Shaanxi, Sichuan, Yunnan provinces).

Additional specimens studied. CHINA, Hupeh [Hubei], Mar.1889, Augustine Henry 5788 ( A barcodes 00277289*, 00040647*, BM barcode 000622276*, CAL barcodes 0000011656, 0000011659, 0000011660, US barcode 00097934*).

Note — We could trace four specimens in A, BM, CAL, GH and US which can be considered to be original material. On examination, we found that Henry 5788 C ( GH barcode 00040646, both twigs) has all the distinct characters as specified in the protologue and thus we selected it as the lectotype and the specimens at CAL (barcodes 0000011653, 0000011655) as isolectotypes .
