Borinda KR 4175 - Himalaya Bamboo

[pierre]

Dr. Chris Stapleton, Royal Botanic Garden Edinburgh, hatte ein Bambus aus Himalaya 1995 nach England mitgebracht und nannte Borinda KR 4175 .  Borinda ist nach dem Botaniker Norman Loftus Bor (1893-1972), der in Indien viele Gräser bestimmt hat. Also eine Namensverknüpfung von Bor und India.

KR 4175 habe  ich 2007 beim Jos van der Palen (http://www.kimmei.com/indexd.htm) erstanden, zuerst hatte ich im Topf gepflanzt ,  habe ich heute raus genommen und nach 2 harte Winter 2009 und 2010 ausgeflanzt..

New combinations in Borinda (Gramineae—Bambusoideae)

Summary. Following fieldwork in Yunnan and the recent introduction of several Sino-Himalayan
bamboos, an additional 10 species are now considered to belong in the genus Borinda Stapleton. B.
albocerea, B. edulis, B. frigidorum, B. fungosa, B. hsuehana, B. lushuiensis, B. papyrifera, and B. perlonga from
Yunnan, and B. fansipanensis from N Vietnam, were all originally described in Fargesia Franch., while B.
schmidiana from S Vietnam was originally described in Arundinaria Michx. This extends the distribution
of Borinda along a continuous belt of mountain ranges from western Nepal to southern Vietnam, and
brings the total number of species in the genus to 18.


The genus Borinda was created for clump-forming temperate Sino-Himalayan
bamboos that could not be accommodated in Fargesia because of their more open
synflorescences, with paniculate rather than racemose branching, and a cylindrical
rather than unilateral arrangement of paraclades. Eight species from Nepal, Bhutan
and Tibet were initially placed in the genus (Stapleton 1994). Field study in Yunnan,
examination of herbarium material, and observation of introduced plants has now
shown that the distribution of the genus is substantially wider, extending along a
continuous chain of mountain ranges from Annapurna in West Nepal, to Lang Bian
Mountain (Lam Vien) in southern Vietnam, only 150 miles from Ho Chi Minh City
(Saigon). An additional ten species are now considered to belong in Borinda,
increasing the number of species in the genus to eighteen.
Borinda was named in honour of Dr Norman Bor, Head of the Grasses Section
and Deputy Director of the Royal Botanic Gardens, Kew, in recognition of his life's
work, most of which was devoted to the forests and grasses of N E India (Hubbard
1975). B. macclureana (Bor) Stapleton is representative of the type of the genus.
Speciation and endemism in these temperate bamboos is apparently high. Valleys
from the high Tibetan plateau, and well-separated peaks arising from the lower
plateau of Yunnan and N Vietnam are all relatively isolated. Many of these montane
habitats are severely threatened by deforestation, over-grazing or mining, and
survival of these bamboos in degraded sites is not assured, especially after flowering.
Nevertheless several Borinda species presently provide non-timber forest products of
considerable economic importance, and their culms are systematically extracted
from remaining areas of natural forest or cultivated clumps.
The majority of the species in this genus were described for the first time in the
1980s, nearly all from sterile material, and often from a very limited number of
collections. Considerable work remains to refine species delimitation, and to relate
newly described species to earlier names based upon inadequate flowering
specimens, many lacking vegetative parts.

Himalaya dürfte unsere Temperaturen aushalten, nur leider unsere Winterfeuchte nicht. Gerade bei Monocots ist stehendes Wasser in den Triebaugen und folgender Frost ein großes Problem. Dort wo er herkommt, Schneit es im November und der Schnee bleibt als Mütze bis März liegen und schützt so vor Nässe und Kälte.
