It is indeed looking like Didymolpexis pallens Griff.
Chowdhery & Pandey (2007) writes- 'It grows on soil thickly covered with humous of decaying leaves and twigs, hidden among grasses and various herbs like Sida cordifolia, Alternanthera sessilis, Typhonium trilobatum, Globba marantina, Cynodon dactylon, Imperata cylindrica, Digitaria sp. etc.'
A
specimen housed in Kew have note that says 'under a clump of bamboo'.
Thank you for arranging picture of this species, we are richer with additional genus and species!
