Grewia

When preparing the Tiliaceae for the Congo Flora, Wilczek (1963) described a species in the genus Grewia based on Homblé 90, collected in China. Grewia katangensis R.Wilczek was published with eleven other novelties recognized during his revision. The species was believed to be related to G. woodiana K.Schum. , but no further comments were given.

Using the Flora of China ( Tang et al. 2007), the Homblé speci- men keys out as Grewia cuspidatoserrata Burret. It has the characteristics of this species: 2-lobed fruits, and abaxially tomentose lanceolate leaf-blades with a symmetrical base. This submontane species is only reported from S Yunnan, where Homblé was not botanizing. The type specimen is dated Sep- tember 1910, so was seemingly collected during the above mentioned trip to Liuzhou, possibly at the mountainous end point of that voyage. Our identification is hence plausible, and Homblé’s specimen might represent the first record of the species for Guangxi.The trip from Guilin was some 150 km toward the SSW, in the direction of S Yunnan, though still 500 km away from it .
