Silktassel
''Garrya'' is a genus of flowering plants in the family Garryaceae native to Mexico, the western United States, Central America and the Greater Antilles. Common names include silk tassel and tassel bush. They are evergreen dioecious wind-pollinated shrubs growing to tall. The leaves are arranged in opposite pairs, and are simple, leathery, dark green to gray-green, ovate, long, with an entire margin and a short petiole. The flowers are gray-green catkins, short and spreading when first produced in late summer; the male catkins becoming long () and pendulous in late winter when shedding pollen; the female catkins usually a little shorter and less pendulous. The fruit is a round dry berry containing two seeds.

Garrya Congdonii
''Garrya congdonii'', the chaparral silktassel or Congdon silktassel, a fairly common evergreen shrub native to the northern California Coast Ranges, is one of a small biological family of approximately twenty known species in the family Garryaceae, most of which are ''Garrya''. While the female and male sexual organs of Congdon silktassel are on separate plants, the pendant male catkins are much more showy. This plant is reasonably attractive and neat enough in its growing habit to be appealing as a landscape species. It is stocked commonly at commercial plant nurseries. All ''Garrya'' are associated with warm temperate regions of North America. Description 240px, Leaves and spent blooms Congdon silktassel has a multi-furcate trunk branching structure yielding an almost spherical form. The height can attain four meters, but more commonly averages two to three meters in the wild. Congdon silktassel, as all the genus ''Garrya'', have opposite leaves that have a tough leathery f ...

Garrya Fadyenii
''Garrya fadyenii'' is a species of flowering shrub known by the common name Fadyen's silktassel.

Dioecious
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Guatemala
Guatemala, officially the Republic of Guatemala, is a country in Central America. It is bordered to the north and west by Mexico, to the northeast by Belize, to the east by Honduras, and to the southeast by El Salvador.

The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica; in the 16th century, most of this was Spanish conquest of Guatemala, conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence from Spain and Mexico in 1821. From 1823 to 1841, it was part of the Federal Republic of Central America. For the latter half of the 19th century, Guatemala suffered instability and civil strife. From the early 20th century, it was ruled by a series of dictators backed by the United States. In 1944, authoritarian leader Jorge Ubico was overthrown by a pro-democratic m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harvard University Herbaria
The Harvard University Herbaria and Botanical Museum are institutions located on the grounds of Harvard University at 22 Divinity Avenue, Cambridge, Massachusetts. The Botanical Museum is one of three which comprise the Harvard Museum of Natural History. The Herbaria, founded in 1842 by Asa Gray, are one of the 10 largest in the world with over 5 million specimens, and including the Botany Libraries, form the world's largest university owned herbarium.

It was originally called the ''Museum of Vegetable Products'' and was predominantly focused on an interdisc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berry (botany)
In botany, a berry is a fleshy fruit without a drupe, drupe (pit) produced from a single flower containing one Ovary (botany), ovary. Berries so defined include grapes, Ribes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines), persimmons and bananas, but exclude certain fruits that meet the berry, culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more gynoecium, carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as ''Capsicum'' species, with air rather than pulp around their seeds. Many berries are edible, but others, such as the Potato fruit, fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that be ...
