Abstract
Based on morphological and molecular data, Glabrella bogaoi, a new species from limestone areas in southern China, is described and illustrated here. G. bogaoi is morphologically distinct from the other species of Glabrella by its stems, which can grow up to 5–30 cm, calyx segments that are adpressed to the corolla base, and corolla outside white. It is morphologically most similar to G. mihieri. Furthermore, a phylogenetic analysis of the combined matrix of trnL-F and ITS sequences, including 4 taxa of Glabrella, has been provided. The phylogenetic analysis indicates that G. bogaoi is an independent new species. A table and a key to distinguish the new species from all other Glabrella species are also provided.

Diagnosis: Glabrella bogaoi is morphologically most
similar to G. mihieri in the shape of the leaf blades, cyme,
and filament characteristics, but differs in stems length,
which is 5–30 cm long (vs. indistinct to 5 cm long),
peduncles 2.5–8.5 cm long [vs. (5–)8–17 cm long], calyx
segments ovate (vs. narrowly ovate to narrowly triangular),
6–8×3–4 mm long (vs. 4–7×1.5–3 mm long), adpressed to
corolla base (vs. spreading), corolla outside white (vs. bluepurple or pale purple to pale yellow), and style glandular
pubescent (vs. glabrescent to sparsely pubescent).
Etymology: The specific epithet commemorates Mr.
Bo-Gao Huang who was the director of the Yachang
Orchid National Nature Reserve and a strong supporter of
scientific research.
