Juncus conglomeratus Linnaeus, Species Plantarum 1: 326. 1753.

"Habitat in Europae borealis uliginosis." RCN: 2530.

Lectotype (Snogerup in Bot. Not. 123: 428. 1970): Herb. A. van Royen No. 904.145-425 (L) .

Current name: Juncus conglomeratus L. ( Juncaceae).

Note: Dandy (in Watsonia 7: 169. 1969) argued that this is a synonym of J. effusus and selected an apparently ineligible van Royen specimen of J. effusus as the lectotype.
