Comments

Differs from Juncus leucanthus Don by its smaller size, whitish perianth segments, capsules not exserted and the lowest bract often much exceeding the flowering head. Juncus leucanthus seems to be confined from Sikkim Himalayas to Kumaon. Its elongated lowest bract and much longer, linear anthers easily distinguish it from Juncus membranaceus Don. It may also be confused with Juncus leucomelas Don but the presence of the cauline leaves and hardly tailed seeds will distinguish it.
