Peristylus plantagineus (Lindl.) Lindl., Gen. Sp. Orchid. Pl. View in CoL 300. 1835. Herminium plantagineum Lindl. Edwards’s Bot. Reg. 18: t. 1499. 1832. Type: SRI LANKA, s.d., Macrae s.n. (K, n.v.).

A terrestrial orchid, endemic to the Western Ghats of India and Sri Lanka. It can be identified in the field by its plantain-like leaves, which are whorled in the middle of the stem, 10–25 cm long densely white flowered spike, trilobed lip, saccate and globose spur, usually shorter than the sepals.

The original material of Peristylus elatus is traced at K. The sheets with barcodes K000387509 and K000387510 have Dalzell’s labels as ‘ Peristylus elata ’ and ‘ Peristylus elatus’ and Hooker’s annotation as ‘ Bombay Dalzell’. The latter, which is more precise and has pencil illustrations of flower parts, is selected here as the lectotype. Another sheet (yet to be digitized) has mixed collections from Dalzell and Law and has Stocks’ orchid label ‘Orchideae no. 43’.
