Sporobolus floridanus, commonly referred to as Florida dropseed, is a species of perennial graminoid, which is endemic to the southeastern region of the United States.[1][2]

Description

Sporobolus floridanus possesses culms that range in height between 1 and 2 m (3.3 and 6.6 ft) and pale blue-green blades that reach a length between 25 and 50 cm (10 and 20 in) and a width between 3 and 10 mm (0.12 and 0.39 in). The blades are glabrous on both sides.[3]

The panicles range between 30 and 50 cm (12 and 20 in) in length and 4 to 15 cm (1.6 to 5.9 in) in width. Spikelets are purple to brown in color and 4 to 6 mm (0.16 to 0.24 in) in length. When fruit is produced it is reddish-brown in color and ranges from 1.7 to 2 mm (0.07 to 0.08 in) across.[3]

Distribution and habitat

The range of S. floridanus is limited to the southeasternmost corner of the United States, with populations found in South Carolina, Georgia, Alabama, and Florida.[4] The majority of the species is located in Florida.[5]

S. floridanus may be found in habitats such as wet pine savannas, bogs, treeless swales, and other mesic environments.[6][4]

It is used an indicator species within mesic flatwood communities in northern Florida.[7]
