Description

Distribution

Ecology

Habitat

Kaczor and Hartnett found that T. dichotomum had signifcantly lower cover on old tortoise mounds and undisturbed plots (1990). Found in the longleaf pine patches that surrounded the golf course in Haile Plantation, Gainesville, Florida.

Phenology

Seed dispersal

Seed bank and germination

High light intensities and large diurnal temperature fluctuations as a result of the tortoise mounds are probably favorable for the establishment of T. dichotomum (Bazzaz 1979 cited by Kaczor and Hartnett 1990).

Fire ecology

Pollination

Mark Deyrup at Archbold Biological Station observed these Hymenoptera species on Trichostema dichotomum

Halictidae: Lasioglossum placidensis

Use by animals

It was found to be one of the most common spring recruits on recently abandoned tortoise mounds (Kaczor and Hartnett 1990). Deyrup (2012) observed the bees, Caupolicana electa and Dialictus placidensis, on T. dichotomum.
