''Krameria bicolor'' is a perennial shrub or subshrub of the family Krameriaceae, the rhatanies. It is commonly known as white rhatany, crimson-beak, and ''chacate'' in Spanish (''cosahui'' in the state of Sonora).

It is a low lying, densely branched shrub, commonly up to , but exceptionally to beyond . The branches are spiny in form but not sharp nor firm at the tips. The leaves are grey-green to greenish, finely-haired, narrow and only one half to three quarters of an inch long. The color of the plant and branches is grayish-green to gray, or whitish-gray, to dull browns or tinged with red. The flowers are often sparse and sometimes inconspicuous, but plants in some locales can bloom prolifically in red flowers. The plant is used for dyes in the basketry of Seri people in Mexico. The shrub is adapted to dry, desert environments, but it can take advantage of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Krameria
''Krameria'' is the only genus in the Krameriaceae family, of which any of the approximately 18 species are commonly known as rhatany, ratany or rattany. Rhatany is also the name given to krameria root, a botanical remedy consisting of the dried root of para rhatany ('' Krameria argentea'') or Peruvian rhatany ('' Krameria lappacea''). The biological action of rhatany is caused by the astringent rhataniatannic acid, which is similar to tannic acid. Infusions have been used as a gargle, a lozenge, especially when mixed with cocaine, as a local hemostatic and remedy for diarrhea. When finely powdered, the dried roots furnished a frequent constituent of tooth powders. The powdered roots have also served, especially in Portugal, to color wines ruby red. The root bark contains an almost insoluble free red substance called ratanhia red. ''Krameria'' are found across the Americas, with most native to the tropical regions. They are perennial shrubs which act as root parasites on othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of The Mojave Desert
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Flora Of Texas
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) 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''. 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 Thurman ...
