Lappula Occidentalis
''Lappula occidentalis'', also known as flatspine stickseed, flatspine sheepburr, western stickseed, ''Lappula redowskii'', or Redowski's stickseed, is a biennial forb native to North America and parts of Europe and Asia. It belongs to the family ''Boraginaceae.'' Variants include ''L. redowskii var. cupulata'' and ''L. redowskii var. redowskii'', which differ in fruit morphology from the type specimen. Description Flatspine stickseed is a flowering herb that reproduces by fruiting. The fruits are divided into four nutlets that have a single row of velcro-like prickles along their edges. The stem is erect, angled, covered in fine hairs that may be appressed to spreading, 5 to 40 cm in height, and may be simple or branched in morphology. Leaves are simple, alternately arranged, with edges that are entire. Both basal and stem leaves are present. Basal leaves are mostly oblong with a rounded tip and tend to wither by flowering time. Leaves along the stem are narrowly lance-oblong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lappula Squarrosa
''Lappula squarrosa'' is a species of flowering plant in the borage family known by several common names, including European stickseed, bur forget-me-not, bluebur, and bristly sheepbur. It is native to Europe and Asia, where it is common, and it is an introduced species in much of North America and Africa. It is well known as a noxious weed where it is naturalized and also in many parts of its native range. This is an annual herb producing an erect stem often with sprays of many long, bending branches, its form varying in different regions and climates. The plant may approach a meter in height. The stems are lined with linear to oval leaves up to 5 centimeters long and coated in whitish hairs, and the herbage emits a scent generally considered unpleasant. The inflorescence is a long, leafy raceme of tiny flowers near the ends of the branches. Each flower is 2 to 4 millimeters wide with five light blue corolla lobes. White-flowered plants are occasionally seen. The fruit is a cluste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boraginaceae Genera
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boraginoideae
Boraginoideae is a subfamily of the plant family Boraginaceae ', with about 42 genera. That family is defined in a much broader sense (Boraginaceae ') in the Angiosperm Phylogeny Group (APG) system of classification for flowering plants. The APG has not specified any subfamilial structure within Boraginaceae ''s.l.'' Taxonomy Some taxonomists placed the genera ''Codon'' and '' Wellstedia'' in Boraginoideae. Others place one or both of these in separate, monogeneric subfamilies. ''Codon'' was long regarded as an odd member of Hydrophylloideae, but in 1998, a molecular phylogenetic study suggested that it is closer to Boraginoideae. Neither is included n more modern classifications. Some authors proposed a revision of earlier APG systems, in which Boraginaceae had been included as an unplaced family (i.e. not included in a specified order) within the lamiid clade of eudicots. In that system. Boraginaceae was defined broadly (Boraginaceae ''sensu lato'' or ''s.l.''). Instead the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is injurious to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forest management, nature reserves, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introduced as ornamental plants for horticultural use. Some "noxious weeds", such as ragwort, produce copious amou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
