Hieracium Hypopogon
''Hieracium'' (), known by the common name hawkweed and classically as (from ancient Greek ιεράξ, 'hawk'), is a genus of flowering plant in the Family (biology), family Asteraceae, and closely related to dandelion (''Taraxacum''), chicory (''Cichorium''), prickly lettuce (''Lactuca'') and sow thistle (''Sonchus''), which are part of the Tribe (biology), tribe Cichorieae. Hawkweeds, with their 10,000+ recorded species and subspecies, do their part to make Asteraceae the second largest family of flowering plants. Some botanists group all these species or subspecies into approximately 800 accepted species, while others prefer to accept several thousand species. Since most hawkweeds reproduce exclusively asexually by means of seeds that are genetically identical to their mother plant (apomixis or agamospermy), Clone (genetics), clones or populations that consist of genetically identical plants are formed and some botanists (especially in UK, Scandinavia and Russia) prefe ...

Hieracium Caespitosum
''Pilosella caespitosa'' (synonym ''Hieracium caespitosum'', commonly known as meadow hawkweed, yellow hawkweed, field hawkweed, king devil, yellow paintbrush, devil's paintbrush, yellow devil, yellow fox-and-cubs, and yellow king-devil) is like several other ''Pilosella'' species and has a similar appearance to many of the hawkweeds. Description ''Pilosella caespitosa'' is a creeping perennial, with shallow, fibrous roots and long rhizomes. The leaves, hairy on both sides (unlike '' Pilosella floribunda'', which looks similar but has hair only on the underside), are up to 6 inches (15 centimeters) long, spathulate, and almost exclusively basal with the exception of 1 or 2 very small cauline leaves. The leaves lie flat to the ground, overlap, and will smother non-vigorous turf. The stems are bristly and usually leafless, although occasionally a small leaf appears near the midpoint. Stems, leaves, and bracts have dense, blackish hairs and exude milky juice when broken. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
