Apologies, that is a bad typo by me. Thanks for picking that up. The calyx teeth were 4. I just re-checked ( live material retained for a herbarium specimen ), so definitely elatinoides even though flowers are white-ish. Leaves are 9 mm long. Oddly, none of the flowers seem to have any stamens but all have a wide stigmatic lobe.
Doubtful for this to be cleistanthum, as its pedicels are very short and fruit develops in soil on downturned pedicels: no hint of downturning here, and pedicels are too long.
