Louis Auguste Joseph Desrousseaux
Louis Auguste Joseph Desrousseaux (27 July 1753 – 20 January 1838) was a French botanist and pteridologist. He was a contributor to the "Encyclopedia Botanique" of Lamarck, from 1783 to 1796. Desrousseaux produced many works on new plant species, creating 414 new records. In 1828, botanist Augustin Pyramus de Candolle (DC.) published '' Rousseauxia'', a genus of flowering plants from Madagascar, belonging to the family Melastomataceae Melastomataceae is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species.

Carya
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four-valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan). It is a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It occurs in damp or dry acidic soils in woods or open woods, from sea level up to 1,200 m altitude. ''Dennstaedtia punctilobula'' can exhibit varying degrees of phototropism. The common name "Hay-scented Fern" comes from the fact that crushing it produces an aroma of fresh hay. The presence of ''Dennstaedtia punctilobula'' influences the dynamics of the understory vegetation of many forests in the eastern United States. An abundance of ''Rubus allegh ...
