Rank Reasons
Utricularia subulata is a wetland annual herb with a broad, pantropical distribution. With a large range extent, over 1000 occurrences, and broad habitat preferences for abundant habitat, this species is considered secure.
Range Extent Comments
Utricularia subulata is native to lower elevations of the United States, Nova Scotia, Canada, Central America, South America, Asia, Africa, and Australia (Crow 2014). Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are estimated to be more than 1000 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, Utricularia subulata is potentially threatened by development, road maintenance, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
Ecology & Habitat

Habitat

Utricularia subulata grows in open areas of wet pine savannas and flatwoods, bogs, clearings of swampy woods, peaty sands or marly wet soils, and wet ditches (Crow 2014).
