Primary tabs

Carex verticillata


Leaves basal and 1-2 on the stem proper, shorter than to equalling the stem, flattish with often strongly revolute margins, stiff, coriaceous, with scabrid margins, asperous above especially towards the long-attenuated apex, 3-8 mm wide; Inflorescence a lax to dense panicle, 15-50 cm long, consisting of 4-7 fascicles of up to 20 spikelets, lower fascicles rather distant, upper approximate.


Asia-Tropical: Jawa (Jawa present); Laos (Laos present); Malaya (Peninsular Malaysia present); Sumatera (Sumatera present), G. Kerbau present, Mt Kinabalu present, N. Borneo present, Perak present, Tonkin present
Laos, Tonkin; in Malesia: Sumatra, Malay Peninsula (Perak: G. Kerbau), Java, N. Borneo (Mt Kinabalu).


Variable as to the colour of glumes and utricles. In most of the Mt Kinabalu specimens the glumes and utricles are very dark; they were distinguished as var. havilandii (Clarke) Nelmes.
A collection from E. Java (G. Semeru), in which the glumes and utricles are pale golden to fulvous, was distinguished as var. lutescens Nelmes.
Carex phacelostachys Nelmes only could be distinguished by the utricles which are faintly nerved against nerveless in C. verticillata. The collection van Steenis 9624 from Atjeh has been identified as C. verticillata by both Nelmes and Kern; after careful examination of the utricles I could not find any difference with C. phacelostachys. I examined many utricles of C. verticillata with translucent light. Most of them are nerveless indeed, but others are faintly nerved, often only at the base, at least in plants from Sumatra and Borneo.
The species might also be conspecific with C. walkeri Arnott ex Boott. — (Noot.).
