23c. Deparia acuta var. liubaensis (Z. R. Wang) Z. R. Wang
[comb. nov.]

六巴对囊蕨 liu ba dui nang jue

Basionym: Lunathyrium vegetius (Kitagawa) Ching var. liubaense Z. R. Wang, Acta Phytotax. Sin. 32: 91. 1994; L. acutum var. liubaense (Z. R. Wang) Z. R. Wang.

Pinna segments 10-13 pairs.

● About 3300 m. Sichuan (Kangding, Liuba).

The spore surface of Deparia acuta var. liubaensis has folded processes, an intermediate character between D. acuta var. acuta and D. vegetior. It is more similar to var. acuta in the long multicellular hairs on the abaxial surface of rachis, costae, and fertile pinnae, and the indusia shortly ciliate at margin. However, the pinna segments are fewer than in var. acuta, and in this character var. liubaensis is similar to D. vegetior. Deparia acuta var. liubaensis occurs in localities between D. acuta and D. vegetior. Their relationship needs further study.
