Ξ Schoenus ruber Lour., Fl. Cochinch. 1: 41. 1790.

Neotypus (designated here): INDIA: Cherrapunji , Khasia, Meghalaya, VIII.2006, Sangita Dey 9923 ( CAL [ 00000 22241 ]! ; iso-: ASSAM)( Fig. 3 ).

Loureiro did not cite any specific type specimen for this taxon, writing only “Habitat in Cochinchina”. According to STAFLEU & COWAN (1979-1988), Loureiro’s specimens are only partly preserved, the main collection is at BM, a small set is at P and some specimens are at LINN. A thorough search of these three herbaria for any Loureiro’s specimen which could be selected as type of R. rubra proved to be futile, and therefore, a specimen with mature fruits collected from Cherrapunji, Khasia, Meghalaya, India in August 2006 is here selected as neotype of R. rubra according to ICBN (Art. 9.11, MCNEILL & al., 2006).
