Carex vesiculosa

Primary tabs

Carex vesiculosa


Leaves coriaceous, basal and 1-2 higher on the stem, usually much shorter than the stems, narrow, long-attenuate, keeled, with strongly revolute margins when dry, scabrous on the margins, often vesiculose-asperous above especially towards the apex, 2-8 mm wide. Inflorescence a decompound, interrupted, ferrugineous, 15-40 cm long panicle;


Asia-Tropical: Jawa (Jawa present); Lesser Sunda Is. (Bali present); Thailand (Thailand present), Flores present, Lesser Sunda Is present, Lombok present, Mt Papandajan present, Nepal present, Timor present, W. Java present, mountains of Central and E. Java present
Nepal to Thailand; in Malesia: Java (in W. Java on Mt Papandajan, not rare in the mountains of Central and E. Java), Lesser Sunda Is. (Bali, Lombok, Flores, Timor).


In old specimens the leaves are often less asperous because the vesiculose (bulbous- based) hairs have broken off. The former presence of vesicles is indicated by small, circular scars.
If C. gembolensis is specifically distinct from C. vesiculosa, its correct name is C. impunctata Boott, based on Zollinger 2563 from Java. This collection Nelmes rightly included in C. gembolensis.
Var. congesta Kuk. (= C. gembolensis var. crebra Nelmes) has no taxonomic value.
