glabrescent

Branchlets pubescent to glabrescent with minute scurfy hairs intermixed with unguicular scales.

小枝短柔到后脱落有微小的鳞屑与爪鳞片混生的。

In Japan the leaf sheaths are always conspicuously tuberculate-hispid; the older, lower sheaths with disarticulated blades are glabrescent and spotted with tubercles.

在日本叶鞘总显著糙瘤；最旧的，更下部的鞘叶片在后脱落和斑点小瘤。
