Alabama Black Cherry
''Prunus alabamensis'', the Alabama cherry or Alabama black cherry, is an uncommon to rare species of tree in the rose family endemic to parts of the Southeastern United States. It is closely related to and found wholly within the range of ''Prunus serotina'', the black cherry, a more common and widespread species of ''Prunus'' also native to the region. Alabama cherry is sometimes considered to be a variety of ''Prunus serotina'' (i.e. ''Prunus serotina'' var. ''alabamensis''), however most authors treat it as a distinct species. Description Alabama cherry is a deciduous flowering plant in the rose family endemic to the Southeastern United States. It is similar to but distinct in morphology from the closely related ''Prunus serotina''. Form Alabama cherry is a small or medium sized tree growing to heights of and a diameter of about , scarcely exceeding in height. Bark The immature bark is gray and smooth; mature bark is rough and becomes broken into plates that are dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Mohr (botanist)
Charles Theodor Mohr (Karl Theodor Mohr; December 28, 1824 – July 17, 1901) was a pharmacist and botanist of German descent who lived and worked in the United States. Early life Born in Esslingen am Neckar, Kingdom of Württemberg, Mohr was the fourth child of lamb farmer August Ludwig Mohr (1795-1833) and Dorothea Catharina Friederica (née Walker). The first three years of school, Mohr spent at the boys' school (paedegogium) of his home town. In 1833 the family moved to nearby Denkendorf where August Mohr founded a mustard and vinegar factory. Later that year, on September 10, August Mohr suddenly died at the age of 38. Early in life, Mohr worked in the family business. He developed an interest in botany through his great-uncle, a forester at the Denkendorf convent, and his uncle's son, a student at the agricultural college in Hohenheim. Through the self-study of several books on botany, Mohr furthered his knowledge in this area and developed a taste for natural science. ...

Leaf Margin
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Drupe
In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pip'' (UK), ''pit'' (US), ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. Drupes do not split open to release the seed, i.e., they are dehiscence (botany), indehiscent. These fruits usually develop from a single carpel, and mostly from flowers with Superior ovary, superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, woody (lignified) stone is derived from the Ovary (botany), ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a Berry (botany), different definition of ''berry''. Other fleshy fruits may have a stony enclosur ...
