Sasa fortunei in the Botanical Garden of Kunming

Sasa called on German as a dwarf bamboo, bamboo is a genus of the subtribes Arundinariinae. The distribution area of ​​about 60 species located in China, Japan, Korea and eastern Russia.

Features

Sasa is a genus of perennial, shrub-like growing bamboo species. The rhizomes are leptomorph and form long, which grow underground shoots. The internodes are thick-walled, terete, glabrous and sometimes white floured among the nodes or sparsely hairy fluffy. The branches grow individually and are often similar in length to the straws. The Halmscheiden are permanent and papery to leathery, almost. Auricles can be formed. The Halmblattspreite is lanceolate. The leaves usually have no auricles. The ligule is a membranous ciliated or unbewimperter hem. The base of the leaf blade has a stalk -like connection to sheath. The leaf blades are arranged very large and palmate compared to the stalks and can transverse leaf veins have. The leaf edges die off in the winter.

As inflorescences loose panicles or grape are formed, the base can be enclosed by a small bract. The spikelets are purple or red at maturity and bear four to eight florets. Fertile spikelets are stalked. The Ährchenachse is not divided and extended the last florets. The glumes are more or less hairy, the Spelzenränder are ciliated long. The lower glume is shorter than the upper, and may even be completely absent. The lemma is ovate or oblong - lanceolate, almost leathery and long mucronate. The palea is doubly keeled. The three corpora cavernosa are ovate, thin, translucent, and have ciliated margins. The six stamens are far out of the florets and have yellow anthers. The ovary is ovoid and wearing only a short style with three feathery scars. As fruits dark brown caryopsis are formed at maturity.

Geographical distribution

The natural range is in China, Japan, Korea and eastern Russia. Eight species are endemic to China.

Use

Due to the large expansion of the rhizomes some species in Japan are used for attachment of shelves.

Diseases

In various species of the rust fungi Puccinia longicornis, Puccinia sasicola and Puccinia mitriformis occur.

System

Sasa is a genus of the tribe bamboo ( Bambusae ) in the family of grasses ( Poaceae ), subfamily bamboo plants ( Bambusoideae ). It is assigned to the subtribes Arundinarieae. The genus was first described in 1901 by Tomitaro Makino and Keita Shibata in the Japanese magazine Botanical Magazine. Synonyms of the genus are Neosasamorpha Tatev. , Nipponobambusa Muroi, Sasaella Makino and Sasamorpha Nakai. The genus name comes from the Japanese and Sasa is probably a short form of Sasai na také, which means " niederwüchsiger bamboo " is.

There are at least two subgenera distinguished:

  • Subgenus Sasa: ​​The stalks and inflorescence axes are not floured know the Halmscheiden are shorter than the internodes, auricles may be present, the branches go off at an angle of 20 to 30 degrees from the stem base, the Laubblattspreiten are colored matt. The subgenus associated with more than 40 species, including guangxiensis Sasa, Sasa longiligulata, oblongula Sasa, Sasa and Sasa rubrovaginata tomentosa.
  • Subgenus Sasamorpha: The stalks and inflorescence axes are floured clearly knows the node are flat or only slightly increased, the Halmscheiden are longer than the internodes, the branches go off at an angle of 10 degrees from the stem base, the Laubblattspreite is shiny. The subgenus are assigned five to 22 species, including hubeiensis Sasa, Sasa and Sasa qingyuanensis sinica.
