Thingia
''Thingia'' is a Monotypic taxon, monospecific genus of flowering plant in the family Montiaceae comprised only by the species ''Thingia ambigua'', known as desert pussypaws. It is native to northwestern Mexico, California, and Arizona, and is found commonly on sandy or silty soil. The sole species of the genus has been housed under several genera before it was split into ''Thingia'': ''Claytonia'' in 1882, ''Calandrinia'' in 1893, and ''Cistanthe'' in 1990. DNA evidence demonstrated that the relationship of ''Thingia ambigua'', then ''Cistanthe ambigua'', to the next closest relative in ''Cistanthe'', ''Cistanthe tweedyi, C. tweedyi'', was actually disjointed. It was found that the two species were most closely related to completely separate South American taxa. Description ''Thingia ambigua'' is an annual plant with fleshy roots. It has stems long that grow outwards and upright. Its leaves are narrow and clasp the stem at their base; each leaf blade is long. It has Inflores ...

Cistanthe
''Cistanthe'' is a plant genus which includes most plants known as pussypaws. These are small, succulent flowering plants which often bear brightly colored flowers, though they vary quite a bit between species in appearance. Some species have flowers that are tightly packed into fluffy-looking inflorescences, the trait that gives them their common name. The genus has a disjunct distribution, with species in California and northeastern Mexico, on the Mexican Pacific Islands, and western and southern South America from Peru to northern and central Chile to northwestern and southern Argentina. Many are adapted to arid environments, with some able to withstand climates that almost completely lack rainfall. ''Cistanthe'' was a genus created to segregate several species previously classified in ''Calandrinia''. Several species from other closely related genera have been moved into ''Cistanthe'' as well. Species , Plants of the World Online accepts 46 species. *''Cistanthe aegialitis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montiaceae
Montiaceae are a family of flowering plants, comprising about 14 genera with about 230 known species, ranging from small herbaceous plants to shrubs. The family has a cosmopolitan distribution. The family Montiaceae was newly adopted in the APG III system and includes members of the Caryophyllales formerly listed in Portulacaceae. It is known by the common names of ''spring beauty family'' or the ''montia family''. Genera 16 genera are accepted:Montiaceae Raf. '' Plants of the World Online

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of California
California native plants are plants that existed in California prior to the arrival of European colonialism, European explorers and colonists in the late 18th century. California includes parts of at least three Phytochorion, phytochoria. The largest is the California Floristic Province, a geographical area that covers most of California, portions of neighboring Oregon, Nevada, and Baja California, and is regarded as a "world hotspot" of biodiversity. Introduction In 1993, ''The Jepson Manual'' estimated that California was home to 4,693 native species and 1,169 native subspecies or varieties, including 1,416 endemic species. A 2001 study by the California Native Plant Society estimated 6,300 native plants. These estimates continue to change over time. Of California's total plant population, 2,153 species, subspecies, and varieties are endemism, endemic and native to California alone, according to the 1993 Jepson Manual study. This botanical diversity stems not only from the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Mexico
Mexico, officially the United Mexican States, is a country in North America. It is the northernmost country in Latin America, and borders the United States to the north, and Guatemala and Belize to the southeast; while having maritime boundaries with the Pacific Ocean to the west, the Caribbean Sea to the southeast, and the Gulf of Mexico to the east.

Flora Of Arizona
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and ...

Venation (botany)
A leaf (: leaves) is a principal appendage of the 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 system. In most leaves, the primary photosynthetic 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 ( adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gynoecium
Gynoecium (; ; : gynoecia) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl (botany), whorl of a flower; it consists of (one or more) ''#Pistil, pistils'' and is typically surrounded by the pollen-producing plant reproductive morphology, reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, Marchantiophyta, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
