Salix Pentandra
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tufted Loosestrife
''Lysimachia thyrsiflora'', the tufted loosestrife, is a plant in the genus '' Lysimachia''. It is native to large sections of the northern Northern Hemisphere, including Eurasia and North America. It often grows in marshes, shorelines of lakes and ponds and occasionally along streams. It is an erect perennial herb growing up to 80 centimeters tall and bearing yellow flowers, sometimes dotted with purple. It may be confused with purple loosestrife when not blooming but can be easily distinguished because purple loosestrife has a square stem. Tufted loosestrife has been used medicinally in Asia to combat high blood pressure. It is a rare species in Britain, where it is found in '' Salix cinerea'' - ''Galium palustre'' wet woodland (community W1 of the British National Vegetation Classification system), '' Salix pentandra'' - '' Carex rostrata'' wet woodland (NVC community W3) and '' Carex rostrata'' - ''Sphagnum recurvum ''Sphagnum recurvum'' is a species of moss belonging t ...
