Hemianthus glomeratus, often known as baby tears or pearlgrass, is a species endemic to Florida, where it grows abundantly in wet depressions and standing water. Long known in error as the similar Hemianthus micranthemoides, it has chasmogamous (pollinated while fully opened) flowers with acute (pointed) calyx lobes, as opposed to the cleistogamous (non-opening and self pollinated) flowers with obtuse (rounded) calyx lobes of the true H. micranthemoides. The two species also differ in their habitat, with H. micranthemoides being a specialized plant of tidal rivers.
