Hesperoyucca Peninsularis
''Hesperoyucca peninsularis'', the peninsular candle or lechuguilla, is a plant species endemic to the Baja California peninsula. It is a perennial forming a rosette. It is semelparous (flowering once then dying).Clary, Karen Husum. 2001The genus ''Hesperoyucca'' (Agavaceae) in the western United States and Mexico: New nomenclatural combinations.Sida 19(4): 839-847. Description Plants are monocarpic or polycarpic, and sometimes rhizomatous. Some form secondary rosettes at their base while others branch their caudex to produce new rosettes after flowering. Taxonomy Phylogeny and classification Although morphological characteristics and phylogenetic ITS analysis show that ''H. peninsularis'' is somewhat distinct from '' H. whipplei'', it is still widely recognized as either a form or a subspecies of ''H.'' ''whipplei''. More conclusive research shows that ''H. peninsularis'' and ''H. whipplei'' form a polytomy, and are sister to '' H. newberryi'', which is consistent wi ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachycereus Pringlei
''Pachycereus'' is a genus of 9–12 species of large cacti native to Mexico and just into southern Arizona, United States. They form large shrubs or small trees up to 15 m tall, with stout stems up to 1 m in diameter. ''Pachycereus'' comes from the ancient Greek παχύς (''pachys'') meaning "thick" and the Latin ''cereus'' meaning "torch". Species ''P. pringlei'' is the tallest cactus species in the world, with a maximum recorded height of 19.2 m.Salak, M. (2000). In search of the tallest cactus.

Flora Of Baja California Sur
Flora is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of 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 flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agavoideae
Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales. It has previously been treated as a separate family, Agavaceae. The group includes many well-known desert and dry-zone types, such as the agaves and yuccas (including the Joshua tree). About 640 species are placed in around 23 genera; they are widespread in the tropical, subtropical, and warm temperate regions of the world. Description and uses Species may be succulent or not. In general, Agavoideae leaves occur as rosettes at the end of a woody stem, which may range from extremely short to tree-like heights, as in the Joshua tree. The leaves are parallel-veined, and usually appear long and pointed, often with a hardened spine on the end, and sometimes with additional spines along the margins. ''Agave'' species are used to make ''tequila, pulque,'' and ''mezcal'', while others are valued for their fibers. They are quite popular for xeriscaping, as many have showy flowers. Sy ...

Cylindropuntia
''Cylindropuntia'' is a genus of cacti (family Cactaceae), containing species commonly known as chollas, native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant. Taxonomy ''Cylindropuntia'' was formerly treated as a subgenus of '' Opuntia'', but have now been separated based on their cylindrical stems (''Opuntia'' species have flattened stems) and the presence of papery epidermal sheaths on the spines (''Opuntia'' has no sheaths). A few species of mat- or clump-forming opuntioid cacti are currently placed in the genus ''Grusonia''. Collectively, opuntias, chollas, and related plants are sometimes called opuntiads. The roughly 35 species of ''Cylindropuntia'' are native to the southwestern and south-central United States, Mexi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agave
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hes ...

Dudleya
''Dudleya'', commonly known as liveforevers (Spanish: ''siemprevivas'') is a genus of succulent plants in the stonecrop family, Crassulaceae, consisting of about 68 taxa in southwestern North America and Guadalupe Island. The species come in multiple divergent forms, some large and evergreen, others cryptic and deciduous, but despite their dramatic variations in appearance, most species readily hybridize. The flowers of ''Dudleya'' have parts numbered in 5, with the petals arranged in tubular, star-shaped, and bell-shaped forms, and when fruiting are filled with tiny, ovoid to crescent-shaped seeds. The genus evolved as neoendemics, from ancestors in the stonecrop genus, ''Sedum.'' The ancestors radiated southward from ''Sedum'' during the creation of the dry summer climate in the California region 5 million years ago. Early botanists classified the larger species as ''Echeveria'' and ''Cotyledon'', while the cryptic species were placed as ''Sedum''. Taxonomic efforts starte ...

Ferocactus
''Ferocactus'' is a genus of large barrel-shaped cacti, mostly with large spines and small flowers. There are about 30 species included in the genus. They are found in the southwestern United States and northwestern Mexico. Description The young specimens are columnar but as they grow older ribs form and they take on a barrel form. Most of the species are solitary but some, such as '' Ferocactus robustus'' and '' F. glaucescens'', have clustering habits. The flowers are pink, yellow, red or purple depending on the species, and the petals sometimes have a stripe of a darker colour. Habitat They are desert dwellers and can cope with some frost and intense heat. The typical habitat is hot and very arid, and the plants have adapted to exploit water movement to concentrate their biomass in areas where water is likely to be present. Like ''Sclerocactus'', ''Ferocactus'' typically grow in areas where water flows irregularly or depressions where water can accumulate for short periods ...

Boojum Tree
''Fouquieria columnaris'', the Boojum tree or ''cirio'' () is a tree in the ocotillo family,(Fouquieriaceae) whose other members include the ocotillos. Some taxonomists place it in the separate genus ''Idria''. It is nearly endemic to the Baja California Peninsula (both the northern and southern states), with only a small population in the Sierra Bacha of Sonora, Mexico. The plant's English name, Boojum, was given by Godfrey Sykes of the Desert Laboratory in Tucson, Arizona and is taken from Lewis Carroll's poem "The Hunting of the Snark". Description This plant is a columniform, upwardly tapering tree. The central axis of the plant is homologous to the single stem of other species. It has a cortical water-storage network, a feature unique to the family. The ''Fouquieria columnaris'' trunk is up to 24 inches (61 centimeters) thick, off-white in color, with few or no major branches and with numerous thin, twiggy branches sticking out at right angles, all covered with small lea ...
