Vietnamosasa pusilla (A.Chev. & A.Camus) Nguyen (1990: 222) .

Basionym: Arundinaria pusilla Chevalier & Camus (1921: 450) .

Type:— VIETNAM. Annam : Lang bian, Dran, 1000-1200 m elevation, A . Chevalier 40600 (lectotype here designated: P02581779 !) .

Neomicrocalamus pusillus (A.Chev. & A.Camus) Demoly (1995: 14) .

Note:—The syntype series cited in the protologue mentions three numbers, Chevalier 40330, 40508 and 40600. Of these, only Chevalier 40600 was found at the Paris herbarium; the type folder also contained a series of plants bearing the number Chevalier 40506. The discrepancy between the collection number of one of the syntypes published in the original description “ Chevalier 40508 ” and the only Vietnamosasa specimens found at P bearing a Chevalier label (“ Chevalier 40506 ”) may be a typographic error in the original publication. However, as we cannot locate the specimens labeled Chevalier 40330, we cannot exclude the possibility that Chevalier 40508 does exist and that the specimen labeled Chevalier 40506 was not intended to be part of the original syntype series by the authors. We thus choose the only available unambiguous specimen, Chevalier 40600, as the lectotype.
