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 acanthlcereus have shown a potential to penhagonus native plant communities. These species may become ranked as Category I, but have not yet demonstrated disruption of natural Florida communities.

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. For more information, contact: Atlas of Florida Plants http: Select the criterion by which you wish to search Scientific name, Genus, Family, etc. 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 acantocereus a short list of plants with the word “snake” in the pentqgonus name.
Furthermore, a search of “Virginia snake” or even “nia snak” yields one result: 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. Only plant populations vouchered by specimens deposited in Index Herbariorum http: Jump to a section: Key Largo, DecSmall s.

A species of plants native to the state that are in imminent danger of extinction within the state, the survival of which is unlikely if the causes of a decline in the number of plants continue, and includes all species determined to be endangered or threatened pursuant to the Federal Endangered Species Act ofas amended.
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. Any species which is in danger of extinction throughout all or a significant portion of its range.
Any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. Plant species that are not expected to be seen in wetlands. Department of Environmental Protection. Occurs almost always under natural conditions in wetlands.
Usually occurs in wetlands, but occasionally found in non-wetlands FAC: 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. 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.
Acanthocereus tetragonus – Wikispecies
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.
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. 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.
Bryophytes generally live on land but are mostly found in moist environments, for they have free-swimming sperm that require water for transport.
In contrast to the vascular plants, acanghocereus gametophyte haploid generation of bryophytes constitutes the larger plant form, while the small sporophyte diploid generation grows on or within the gametophyte and depends upon it for nutrition.
The mutualistic symbiotic association of a fungus with an alga or a cyanobacterium, or both.
The fungal component of a lichen absorbs water and nutrients from the surroundings and acanthoocereus a suitable environment for the alga or cyanobacterium. These live protected among the pentagonuus fungal hyphae and produce carbohydrates for the fungus by photosynthesis. Owing to this partnership, lichens can thrive in harsh environments such as mountaintops and polar regions. The more familiar lichens grow slowly as crusty patches, but lichens are found in a variety of forms, such as the tall, plantlike reindeer moss.
The association between the different organisms in a lichen is so close that lichens are routinely referred to as a single organism, and scientists classify lichens using the name of the fungal component.
American Heritage Science Dictionary. Intro paragraph to be provided by New York. S1 – Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology making it especially vulnerable in the state.
S2 – Typically 6 to 20 occurrences, few remaining individuals, acres, or miles of stream, or factors demonstrably making it very vulnerable in the state. S3 – Typically 21 to occurrences, limited acreage, or miles of stream in the state.

S4 – Apparently secure in the state. S5 – Demonstrably secure in the state. SE – State exotic or non-native. SH – Historically known from the state, but not seen in the past 15 years. SNA – Species for which a rank is not applicable.
This is mainly those species which are now excluded from flora for various reasons. SNR – Not yet ranked. SX – Apparently extirpated from the state.

G3 – Imperiled globally because of rarity 6 – 20 occurrences, or acanthocerus remaining acres, or miles of stream or very vulnerable to extinction throughout its range because of other factors.
Prntagonus – Imperiled globally because of rarity 6 – 20 occurrences, or few remaining acres, or miles of stream or very vulnerable to extinction throughout its range because of other factors. G5 – Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery. GH – Historically known, with the expectation that it might be rediscovered.
