An epiphytic orchid distributed in India , Sri Lanka, and Thailand. I can be identified by its simple raceme, yellow sepals, and petals with red margins, yellowish or white lip, purplish lateral lobes and dilated conical spur.

We could locate three sheets and two drawings of Sarcanthus peninsularis housed at K and GH. The sheet K000942275 has been labelled by Dalzell as ‘ Sarcanthus peninsularis mihi…’ It also has pencil illustrations of flower parts. The remaining sheet at K is not digitized yet, and it has Stocks’ label ‘Orchideae no. 35’. A sheet from Harvard (GH00103899) has Dalzell’s label in the same ink as in sheet at K (K000942275), but the only difference in the GH sheet is that Dalzell has written ‘in Hook. Jour.’, which perhaps was collected later, after the publication of the species. As in the protologue, Dalzell mentioned ‘ Ic. ined. ’, which is referrable to colour drawing at K with an annotation as ‘ Sarcanthus peninsularis mihi’, the habit of drawing agreeing with the top right specimen on K000942275. After comparing drawings and, specimens of S. peninsularis , a sheet at K (K000942275) that is unequivocally in agreement with the description is designated here as the lectotype.
