Distribution Map: Based on vouchered plant specimens from wild populations. Cultivated occurrences are not mapped. View county names by placing the cursor over the map. Show these synonyms only. Category I - Species that are invading and disrupting native plant communities in Florida. This definition does not rely on the economic severity or geographic range of the problem, but on the documented ecological damage caused.

Category II - Species that have shown a potential to disrupt native plant communities. These species may become ranked as Category I, but have not yet demonstrated disruption of natural Florida communities.

Butterwick, N. Melvin, and W. Phytoneuron Identifying species that appear as waifs or only periodically appear in the flora for a few seasons. This numeric rank provides the relative rarity for each species based on a scale from 1 very rare to 5 common.

These ranks carry no legal status. Each species' global rank is determined by NatureServe. These ranks carry no legal weight. The global rank reflects the species worldwide rarity. Wunderlin, R. Hansen, A. Franck, and F. Landry and K. Select the criterion by which you wish to search Scientific name, Genus, Family, etc. Hint: Correct spelling is necessary for desired results, but because this function is a string search the full name need not be entered. Any correct part of a taxon name can be entered and a choice of the correct one made from the small list of resulting matches.

For example, matching the full name exactly in a Scientific Name search for Piptochaetium avenacioides may be difficult, but strings of either tium aven or avenaci or m avenac or pipto will all result in very small lists of matches. The intended name can then be chosen from any of those lists.

Usually, the last letter or two of a given genus, a space, and the first few correct letters of the specific epithet will provide a sufficiently short list containing the desired taxon. A similar example in a Common Name search is Virginia snakeroot. Searching using "snake root" will yield no results due to the extra space, but searching "snake" will generate a short list of plants with the word "snake" in the common name.

Furthermore, a search of "Virginia snake" or even "nia snak" yields one result: Virginia snakeroot. If, after following the above advice, then difficulties are still encountered please use the "browse" feature. A voucher specimen is a pressed and thoroughly dried plant sample deposited in a herbarium, and is intended to be a permanent record supporting research purposes.

A voucher may be a record of a plant's occurrence in a particular area, or a specific example of a plant used in a scientific investigation. Proper vouchers display all the necessary attributes for complete identification of the plant, and are to be accompanied by accurate locality, habitat, collection time, and collector data.

Defined as species of plants native to the state that are in rapid decline in the number of plants within the state, but which have not so decreased in such number as to cause them to be endangered.

OBL: Obligate wetland. Occurs almost always under natural conditions in wetlands. Usually occurs in wetlands, but occasionally found in non-wetlands FAC: Facultative. OBL: Obligate Wetland. FAC: Facultative. UPL: Obligate Upland. Annual: Plants that perform their entire lifecycle within a single growing season.

All roots, stems, and leaves die at the end of the growing season. Over wintering seeds allow the next generation to appear. Biennial: A plant that is typically vegetative its first year and blooms the following season. Once it has bloomed and set seed, the plant dies. Garlic mustard is an example of a biennial. Perennial: These plants live for three or more seasons. Many perennials may not be mature enough to bloom during its first year.

Perennial wildflowers re-grow each season from overwinter root material. Vascular: Any of various plants that have the vascular tissues xylem and phloem. The vascular plants include all seed-bearing plants the gymnosperms and angiosperms and the pteridophytes including the ferns, lycophytes, and horsetails. Also called tracheophyte. Bryophyte: A large group of seedless green plants including the mosses, liverworts, and hornworts.

Bryophytes lack the specialized tissues xylem and phloem that circulate water and dissolved nutrients in the vascular plants.


Ludwigia leptocarpa

Ludwigia peploides is a species of flowering plant in the evening primrose family known by the common names floating primrose-willow and creeping water primrose. It is native to many parts of the Americas, but it can be found on many continents and spreads easily to become naturalized. It is well known as a troublesome aquatic noxious weed that invades water ecosystems and can clog waterways. This is perennial herb which grows in moist to wet to flooded areas.

The specific epithet L. Capsules longitudinally or poricidally multiseriate, rarely uniseriate. Most of the erect species produce basal offshoots, which have ovate to obovate leaves, in the late summer and fall. Bracteoles occur in pairs on the pedicel or stipe or on the base of the hypanthium. Leaves alternate, elliptic, pubescent, to 12 cm long and 3 cm wide; sessile or subsessile.


Ludwigia leptocarpa Nutt. Ludwigia leptocarpa originates most probably from the New World, where it occurs from the United States and the West Indies south to Peru and Argentina. In the Old World it is found all over tropical Africa and Madagascar. The leaves of Ludwigia leptocarpa are collected from the wild and yield a black dye used in East Africa Pemba, Tanzania to blacken mats, baskets and bags made of palm leaves. In the Central African Republic the whole plant is burnt to produce a vegetable salt.


One of the largest of these is Ludwigia leptocarpa , the Anglestem Primrose-willow. Pictured below is a single plant of L. Ludwigia leptocarpa Anglestem Primrose-willow Shrub. Ludwigia leptocarpa Anglestem Primrose-willow Hedge of Shrubs. In fact, another common name for this plant is Longpod Primrose-willow.
