Single-stem trees can be grown in less fertile upland areas.
单干树木可在不甚肥沃的高山地区种植。
Main stem undeveloped; fertile stems several, arising from rosette, diffuse or ascending, 15--50(--100) cm, glabrous or puberulent on 1 side, very rarely densely hirsute. Basal leaves with blade linear, 5--15(--30) cm × 6--9 mm, margin ciliate only proximally; cauline leaves shorter, ciliate only on 1 side of sheath mouth, glabrous elsewhere, very rarely densely hirsutulous.
根状茎无。主茎不发达；能育茎数个，基生叶具线形的叶片，5-15(-30)厘米×6-9毫米，只下部的边缘具缘毛；茎生叶短，仅在鞘口部一边具缘毛，在别处无毛，极少浓密具微糙硬毛。
Main stem undeveloped, short, with basal, rosulate leaves; fertile stems 2--4, arising from base of main stems, usually erect, sometimes ascending, to 50 cm. Basal leaves with sheath sparsely hirsutulous throughout, sometimes proximal ones hirsute only along mouth slit; blade linear, 15--35 × 0.6--1.5 cm, glabrous.
