1. Rhynchospora hookeri Boeck. in Linnaea 37: 621.1873.

Lectotypus (designated here): INDIA: “Hook. et Thoms. Herb. Ind. Or.”, Indic. Orient., Mt. Khasia, s.d., Hooker & Thomson s.n. (CAL [0000022242]! ; iso-: K [000357553]!) (Fig. 1).

Boeckeler cited “‘Hook. etThoms. Herb. Ind. Or.’, Indic. Orient,Mont.Khasia” as the type of thisspecies. The specimen deposited in CAL, having the original label of “Hook. et Thoms.” is designated as lectotype of this species and replaces the material formerly deposited at B, which was destroyed during the Second World War (R. Vogt, pers. comm., 2005). However, Boeckeler identified the specimen as Cephaloschoenus articulatus Nees, written on the original label of the specimen at CAL which further confirmsthat the duplicateof the CAL specimen was studied by Boeckeler. Critical examination of the specimen reveals that it belongs to Rhynchospora hookeri Boeck. (not Cephaloschoenus articulatus Nees, presently known as Rhynchospora corymbosa (L.) Britton) and confirms C. B. Clarke’s observation (CLARKE, 1908).
