Comments:— Utricularia pusilla can be confused with U. subulata , but it differs by its sterile bracts on the raceme axis, sepals with prominent nerves and spur up to twice as long as the lower lip (vs. absence of sterile bracts on the raceme axis, sepals with non-prominent nerves and spur as long as or longer than the lower lip). This species is found in a wide altitudinal range and different phytophysiognomies.
