Bamboo subfamily of plants

The bamboos are evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. The word "bamboo" comes from the Kannada term bambu (ಬಂಬು), which was introduced to English through Indonesian and Malay.

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. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.



Culm is bright green when young, which becomes yellowish green in mature and turns yellowish brown when drying. Young shoots are purplish green in color. Culm is straight. Branching only at top. Aerial roots absent. Internode length is 15–30 cm, and diameter is 3–8 cm. Culm walls are very thick which is almost solid with a very small lumen. Node prominent.

Culm sheath is yellowish green in young plants turns straw colored when mature. It is cylindrical with a triangular blade. Length of the sheath proper is 12.5–17 cm in length and 10–13 cm wide. Blade length is 3–5 cm. Auricles are small. Upper surface of the sheath covered with hairs. Lower surface of the sheath is not hairy. Sheaths persistent.

<i>Bambusa vulgaris</i> species of plant

Bambusa vulgaris, common bamboo, is an open-clump type bamboo species. It is native to Indochina and to the province of Yunnan in southern China, but it has been widely cultivated in many other places and has become naturalized in several. Among bamboo species, it is one of the largest and most easily recognized.

Arundinaria appalachiana, commonly known as hill cane, is a woody bamboo native to the Appalachian Mountains in the southeastern United States. The plant was elevated to the species level in 2006 based on new morphological and genetic information and was previously treated as a variety of Arundinaria tecta. As a relatively small member of its genus, it usually only attains heights of 0.5 to 1.0 metre with an either dense or diffuse habit. It is one of only three temperate species of bamboo native to North America. Hill cane is common on dry to mesic sites on upland slopes, bluffs and ridges in oak-hickory forests. In contrast to its sympatric relatives, Arundinaria gigantea typically appears along perennial streams, while A. tecta is found in swamps and other very wet areas.

Bambusa lako, known as Timor black bamboo, is a large species of bamboo originating from the island of Timor; its black culms may reach 21 m (69 ft) in height. A 2000 molecular study places it as closely related to the similar Indonesian species Gigantochloa atroviolacea, from which it was separated in 1997; it may soon be placed in that genus. Bambusa lako can only be grown in climates that are mostly frost free.

Engleromyces sinensis is a species of fungus in the family Xylariaceae. It was described as new to science in 2010, based on specimens collected in 1958 and incorrectly identified as Engleromyces goetzii. The fungus is known only from China, where it grows on bamboo culms. It forms fruit bodies in the shape of two roughly circular buff-colored lobes measuring up to 50 cm (20 in) in diameter that envelop the bamboo. E. sinensis has been used as a folk remedy against cancer and infection in Tibet, Yunnan, and Sichuan Provinces. Several bioactive metabolites have been isolated and identified from the fungus.
