| 中文摘要 | Polystichum minutissimum (sect. Haplopolystichum, Dryopteridaceae) from a karst cave in southern Guizhou, China, is described as new. Polystichum minutissimum is the smallest species in the genus. It is morphologically most similar to P liboense, a species also described from a limestone area in southern Guizhou, but differs from P liboense in lacking hydathodes near the margin of the pinnae. Additionally, P minutissimum has much smaller lamina (1.3-3.8 x 0.7-1.1 cm) and pinnae (middle ones 2.9-5.8 x 2.8-4.5 mm). In fact, it has the smallest lamina and pinnae in the genus. Polystichum minutissimum grows in cool, moist, and twilight conditions in a cave, where it can be extremely sensitive to environmental changes, thereby raising concern for its conservation. |
