Crossosomataceae
Crossosomataceae is a small plant family, consisting of four genera of shrubs found only in the dry parts of the American southwest and Mexico. This family has included up to ten species in the past, although as of 2021 six species are still recognised. ''Crossosoma'' are shrub-like plants which can vary from being 50 cm to 5 meters tall, with small alternating leaves that surround the stem, or leaves clustered in small spurts (fascicles).Richardson, P. (1970). Morphology of the Crossosomataceae. I. Leaf, Stem and Node. Bulletin of the Torrey Botanical Club, 97(1), 34-39. doi:10.2307/2483988 ''Apacheria'', however, has opposite leaves. ''Crossosoma'' has usually white flowers that are generally bisexual and have 5 petals attached to a nectary disk, but in ''Velascoa'' the flowers are campanulate and have an extremely reduced nectary disk.

Glossopetalon
''Glossopetalon'' is a small genus of shrubs in the plant family Crossosomataceae. These plants are sometimes called greasebushes. They are native to Mexico and the western United States, where they can be found on dry mountain slopes. These are usually small shrubs, although ''Glossopetalon spinescens'' can reach up to three metres in favoured locations. They have thorny, tangling branches and white flowers with petals that are easily shed, giving them an untidy appearance. Glossopetalon pungens, ''G. pungens'' is not thorny, and is a vertically prostrate subshrub which is usually found as a small tangled mat of stems hugging sheer cliffs. ''Glossopetalon'' was Species description, described by the American botanist Asa Gray in 1853. Gray first placed his new genus in the Celastraceae Family (taxonomy), family, but twenty years later thought it was most closely related to ''Staphylea'', then in the Sapindaceae, and a few authors accepted this classification at the time (1880).

Velascoa
''Velascoa'' is a monotypic genus of flowering plants belonging to the family Crossosomataceae. It only contains one known species, ''Velascoa recondita'' Calderón & Rzed. It is native to a single location (as far as known at the time of discovery) in Landa de Matamoros Municipality in Querétaro in central Mexico. The genus name of ''Velascoa'' is in honour of José María Velasco Gómez (1840–1912), a Mexican painter, polymath and naturalist. The Latin specific epithet of ''recondita'' means 'hidden', and was chosen to allude to being found in truly hidden locations, far from roads and villages, and for its habit of growing hidden in cracks amongst limestone boulders on inaccessible, vertical cliffs. Because of the harsh climate, it took botanists five years, after discovering the plant, to collect flowers and mature fruit of an individual to make a good holotype, so the new species could be properly described. It was first described and published in 1997 in volume 39 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crossosoma Bigelovii
''Crossosoma bigelovii'', known by the common name ragged rockflower, is one of only a few species in the flowering plant family Crossosomataceae. It is native to the Mojave, Chihuahuan, and Sonoran Deserts of North America. It has been reported from the states of Arizona, California, Nevada, Baja California, Chihuahua, and Sonora.

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
