"Closely related to Trisetella triglochin but T lasiocjila has a lip with 4 carinae arranged in 2 pairs, the basal ones larger and superposed to te small, forward pair. The apex of the lip has a densely pubescent, thickened, cushion-like callus, a unique feature in the T triglochin complex. The column as well has variations in the clinandrium which is prominent and cl;early dentate-erose and the column length exceeds the length of the lip." Pupulin 2000
