Category
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. 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, the 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.
Lichen: 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 provides a suitable environment for the alga or cyanobacterium. These live protected among the dense 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.

State Rank

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.

  • 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 New York State.
  • S2 - Typically 6 to 20 occurrences, few remaining individuals, acres, or miles of stream, or factors demonstrably making it very vulnerable in New York State.
  • S3 - Typically 21 to 100 occurrences, limited acreage, or miles of stream in New York State.
  • S4 - Apparently secure in New York State.
  • S5 - Demonstrably secure in New York State.
  • SE - State exotic or non-native
  • SH - Historically known from New York 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 New York State.
 
Global Rank

Each species' global rank is determined by NatureServe. These ranks carry no legal weight. The global rank reflects the species worldwide rarity.

  • G1 - Critically Imperiled — At very high risk of extinction or elimination due to very restricted range, very few populations or occurrences, very steep declines, very severe threats, or other factors.
  • G2 - Imperiled — At high risk of extinction or elimination due to restricted range, few populations or occurrences, steep declines, severe threats, or other factors.
  • G3 - Vulnerable — At moderate risk of extinction or elimination due to a fairly restricted range, relatively few populations or occurrences, recent and widespread declines, threats, or other factors.
  • G4 - Apparently Secure — At fairly low risk of extinction or elimination due to an extensive range and/or many populations or occurrences, but with possible cause for some concern as a result of local recent declines, threats, or other factors.
  • G5 - Secure — At very low risk of extinction or elimination due to a very extensive range, abundant populations or occurrences, and little to no concern from declines or threats.
  • GH - Possibly Extinct — Known from only historical occurrences but still some hope of rediscovery.  Examples of evidence include (1) that a species has not been documented in approximately 20-40 years despite some searching and/or some evidence of significant habitat loss or degradation; (2) that a species has been searched for unsuccessfully, but not thoroughly enough to presume that it is extinct or eliminated throughout its range.
  • GNA - Not Applicable — A conservation status rank is not applicable because the species is not a suitable target for conservation activities. A global conservation status rank may be not applicable for several reasons, related to its relevance as a conservation target. Typically the species is a hybrid without conservation value, or of domestic origin.
  • GNR - Global rank not yet assessed.
  • GX - Presumed Extinct — Not located despite intensive searches and virtually no likelihood of rediscovery.

Search Help

Select the criterion by which you wish to search (Scientific name, Genus, Family, etc.) and enter that information into the provided field.

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.

 
Definition: Vouchered Specimen

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://sweetgum.nybg.org/science/ih/) recognized herbaria are represented on this map.
