Description
H. punctatum is a perennial forb/herb of the Clusiaceae family native to North America. [1]
Distribution
H. punctatum is found throughout the eastern United States and up into Eastern Canada, specifically Ontario and Quebec. [1]
Ecology
Habitat
H. punctatum has a low tolerance for drought. It is tolerant of shade. [1] It is commonly found in fields and woodland borders.[2] This species also prefers partial shade, and has a low tolerance for calcium carbonate.[3] Specimens of H. punctatum have been collected from upland pinelands that are annually burned, and other similar sandhill habitats that are well-drained.[4] It has also been recorded in outcrop oak hickory forests.[5]
Phenology
Flowers bloom in the early summer months.[1] It commonly flowers between June and September.[2]
Seed dispersal
This species is thought to be dispersed by gravity. [6]
Fire ecology
H. punctatum is not a fire resistant forb but has a mild tolerance to fire. [1]
Pollination
This species is considered by pollination ecologists to be of special value to bumble bees since the flowers attract such large numbers for pollination.[3]
Use by animals
It has been recorded to be eaten by white-tailed deer.[7]
Conservation and Management
It is considered vulnerable in the Canadian province Quebec, critically imperiled in Nebraska, and an exotic species in the Canadian province Newfoundland.[8]
