Hellwigia dekockii Senjaya & A. D. Poulsen 2025, comb. nov.

Hellwigia dekockii (Valeton) Senjaya & A. D. Poulsen comb. nov. Alpinia dekockii Valeton, Nova Guinea 8: 949 1913 (Basionym). Type: Papua, Mount Goliath [Peak Yamin, Jayawijaya Mts.], A. C. de Kock 17 (lectotype: designated here, BO! [Sheet No. BO-0080572]) Notes. In the protologue, Valeton (1913) cited “ de Kock n. 1911, ” which was previously interpreted as a collection number. The specimen housed at BO is labelled as de Kock No. 17 and also bears an annotation reading “ AC. de Kock 22 M. 1911, ” which appears to be the source of confusion. The de Kock No. 17 specimen, as cited in the protologue, was collected from the Goliath Mountain.
