Rubus eucalyptus Focke (1911) 169

Rubus lasiostylus forma glandulosus Focke (1891) t. 1951 (as ‘forma glandulosa ’).

Type. Henry 5427 (lectotype designated here, K barcode 000737813*, http://specimens.kew.org/herbarium/ K000737813 ; isolectotypes BM,barcode 000885494*, P barcode 00755212*), Central China, Hupeh, So Patung, March 1889. — Fig. 2d .

Diagnostic characters — Stem, branches, petioles and pedicels glandular. Leaves rhombic-ovate, thin grey-tomentose abaxi- ally. Flowers white.

Distribution — This species is only reported from China (Gansu, Guizhou, Hubei, Shaanxi, Sichuan).

Additional specimens studied. CHINA, Central China, Hupeh, Cheinshih, Henry 5872 ( CAL 0000011658, GH barcode 00040580*, NY barcode 00429691*, US 00097935*); Western China, Chienshi, E. H. Wilson 950 ( A barcode 00040584*, NY barcode 429677*).

Notes — Focke (1911) while describing this species included the type specimen of Rubus lasiostylus forma glandulosus . Later, Lu & Boufford (2003) also synonymized forma glandulosus under R. eucalyptus as the characters are overlapping. We found three specimens of R. eucalyptus ( A. Henry 5427) each from K * (barcode 000737813), BM * (barcode 000885494) and P * (barcode 00755212). The specimen at K * is best fitted to the protologue and it also bears author’s annotations and hence selected here as lectotype ( Fig. 2d ) and the rest of the specimens as isolectotypes.
