![]() ![]() The global rank reflects the species worldwide rarity. SX - Apparently extirpated from New York State.Įach species' global rank is determined by NatureServe.This is mainly those species which are now excluded from flora for various reasons. SNA - Species for which a rank is not applicable.SH - Historically known from New York State, but not seen in the past 15 years.S5 - Demonstrably secure in New York State.S4 - Apparently secure in New York State.S3 - Typically 21 to 100 occurrences, limited acreage, or miles of stream 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.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.This numeric rank provides the relative rarity for each species based on a scale from 1 (very rare) to 5 (common). (Definitions from: American Heritage Science Dictionary) 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. 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. Owing to this partnership, lichens can thrive in harsh environments such as mountaintops and polar regions. These live protected among the dense fungal hyphae and produce carbohydrates for the fungus by photosynthesis. The fungal component of a lichen absorbs water and nutrients from the surroundings and provides a suitable environment for the alga or cyanobacterium. The mutualistic symbiotic association of a fungus with an alga or a cyanobacterium, or both. 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. Bryophytes generally live on land but are mostly found in moist environments, for they have free-swimming sperm that require water for transport. Bryophytes lack the specialized tissues xylem and phloem that circulate water and dissolved nutrients in the vascular plants. Also called tracheophyte.Ī large group of seedless green plants including the mosses, liverworts, and hornworts. The vascular plants include all seed-bearing plants (the gymnosperms and angiosperms) and the pteridophytes (including the ferns, lycophytes, and horsetails). Species which are likely to become threatened in the near future throughout all or a significant portion of their range within the state if causal factors continue unchecked.Īny of various plants that have the vascular tissues xylem and phloem. Department of the Interior, as enumerated in the Code of Federal Regulations 50 CFR 17.11. restricted to not less than 4 or more than 7 U.S.G.S.1,000 to fewer than 3,000 individuals, or.Department of Interior, as enumerated in the Code of Federal Regulations 50 CFR 17.11. species listed as endangered by the U.Each protected plant so picked, plucked, severed, removed, damaged or carried away shall constitute a separate violation." At this time, the Atlas only identifies those species listed as threatened or endangered. Part (f) which reads as follows: "It is a violation for any person, anywhere in the state to pick, pluck, sever, remove, damage by the application of herbicides or defoliants, or carry away, without the consent of the owner, any protected plant. Warning: Seek medical attention if ingested.(New York): Rare plants are protected under New York State Environmental Conservation Law section 9-1503. The stiff hairs on the leaves and stems can cause skin irritation. Repeat exposure may lead to liver failure. Ingestion may cause delayed liver damage. Symptoms: All parts of the plant are poisonous. The leaf base is tapered into the stem giving a winged appearance.įruit/Berries: The fruit is a shiny, smooth black nut to 6mm. Leaves: Leaves are covered with stiff hairs, oval to lance-shaped, arising from a basal rosette, decreasing in size towards the top of the plant larger leaves to 25cm long. Cultivated for culinary or medicinal use.įlowers: Flowers are mauve, purple or creamy yellow, bell-shaped and in clusters along one side of the flower stem, often drooping downwards. General description: A coarse, vigorous, clumping, tuberous perennial herb covered with stiff hairs growing to 90cm tall and up to 50cm wide. ![]()
