Description
This species is a perennial graminoid in the Poaceae family. Within the Atlantica and Gulf Coastal Plain, H. hemitomon is wetland obligate [2].
Distribution
H. hemitomon can be found from Texas to southern New Jersey, but it is most common in Florida.[2] More specifically, it is distributed from the southeastern coastal plain from southern New Jersey south to Florida, west to Texas, and also in Tennessee, and ranges farther south to South America.[1]
Ecology
Habitat
Generally, Hymenachne hemitomon can be found in river, lake and pond shores, marshes, ditches, swamp borders, and most often in shallow water. It also commonly forms dense colonies located in shallow waters and low margins of limesink ponds.[1] This species is frequently found at swamp margins and marshy drainage canals in wet soil or shallow, standing water [3]. Sandhills and wetlands are possible habitats for Hymenachne hemitomon.[4] Within the Atlantic and Gulf Coastal Plain, H. hemitomon is considered an obligate wetland species that can only be found in wetland habitats.[2]
Phenology
H. hemitomon has been observed to flower from the beginning of may to mid August [3], but flowering is most common from June to July [1].
Conservation and Management
