Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ziziphus Obtusifolia
''Ziziphus obtusifolia'' is a species of flowering plant in the buckthorn family known by several common names, including lotebush, graythorn, gumdrop tree, and Texas buckthorn. Distribution The plant is native to the South Central and Southwestern United States, the California deserts, and central through northern Mexico. It grows in shrubby and scrubby desert habitats, grasslands and prairie, woodlands, and other habitat types. It can be found among desert plants such as honey mesquite, smooth mesquite, ocotillo and creosote. Description ''Ziziphus obtusifolia'' is a shrub with many branches forming a thorny tangle which may exceed tall and approach at times.

Cucurbitoideae
The Cucurbitoideae are a subfamily of the flowering plant family Cucurbitaceae (gourds). The Cucurbitaceae are divided into two subfamilies, the Zanonioideae, probably a paraphyletic group of remainders, and the well-supported monophyletic Cucurbitoideae. The subfamily Cucurbitoideae consists of eight tribes. Members of the tribe Cucurbiteae produce economically valuable fruits, called gourds, which include crops like squashes (including pumpkins), luffas, and melons (including watermelons). The tribe Benincaseae contains a genus called ''Lagenaria ''Lagenaria'' is a genus of gourd-bearing vines in the squash family (Cucurbitaceae). ''Lagenaria'' contains six species, all of which are indigenous to tropical Africa. References ...

Bouteloua Eriopoda
''Bouteloua eriopoda'', commonly known as black grama, is a perennial prairie grass that is native to the Southwestern United States. Its main means of reproduction is by stolons, as its ratio of viable seeds to sterile ones is naturally low. The disparity may play a role in its lack of tolerance to overgrazing (relative to other grasses), but aside from this ''B. eriopoda'' is a good forage food for livestock. It was first described, as ''Chondrosum eriopodum'', in 1848 from specimens collected along and nearby the "Del Norte" river in New Mexico. Distribution ''B. eriopoda'' is found in the following U.S. states: Arizona, California, Colorado, Kansas, New Mexico, Nevada, Oklahoma, Texas, Utah and Wyoming Wyoming () is a U.S. state, state in the Mountain states, Mountain West subregion of the Western United States.

Bouteloua Curtipendula
''Bouteloua curtipendula'', commonly known as sideoats grama, is a perennial, short prairie grass that is native throughout the temperate and tropical Western Hemisphere, from Canada south to Argentina. The species epithet comes from Latin "shortened" and "hanging". Description Sideoats grama is a warm-season grass. The culms (flowering stems) are tall, and have alternate leaves that are concentrated at the bottom of the culm. The leaves are light green to blue-green in color, and up to across. The flowers bloom in summer and autumn. They consist of compact spikes that hang alternately in a raceme along the top of the culm. The spikes often fall to one side of the stem, which gives the plant its name. There are 10–50 spikes per culm, and in each spike there are three to six spikelets, or rarely as many as 10. Each spikelet is long and consists of two glumes and two florets. One of the florets is fertile, and has colorful orange to brownish red anthers and feathery ...

Opuntia Engelmannii
''Opuntia engelmannii'' is a prickly pear common across the south-central and Southwestern United States and northern Mexico. It goes by a variety of common names, including desert prickly pear, discus prickly pear, Engelmann's prickly pear in the US, and nopal, abrojo, joconostle, and vela de coyote in Mexico. The nomenclatural history of this species is somewhat complicated due to the varieties, as well as its habit of hybridizing with ''Opuntia phaeacantha''. It differs from ''Opuntia phaeacantha'' by being green year round instead of turning reddish purple during winter or dry seasons, as well as having yellow flowers with red centers.

Senegalia Greggii
''Senegalia greggii'', formerly known as ''Acacia greggii'', is a species of tree in the genus ''Senegalia'' native to the southwestern United States and northern Mexico, from the extreme south of Utah south through southern Nevada, southeast California, Arizona, New Mexico and western Texas to Baja California, Sinaloa and Nuevo León in Mexico. The population in Utah at 37°10' N is the northernmost naturally occurring ''Senegalia'' species anywhere in the world. Common names include acacia bush, catclaw acacia, catclaw mesquite, Gregg's catclaw, paradise flower, wait-a-minute bush, and wait-a-bit tree; these names mostly come from the fact that the tree has numerous hooked prickles with the shape and size of a cat's claw which tend to hook onto passers-by; the hooked person must stop ("wait a minute") to remove the prickles carefully to avoid injury or shredded clothing. (The common name "cat's claw" is also used to refer to several other plant species, including ''Uncaria tomen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
