....  The grove is called Pando, which is Latin for "I spread" -- and spread it does. The grove is actually a single clonal colony of a male Quaking Aspen. Simply put, it is essentially one massive root system that began life an estimated 80,000 years ago. The root system currently has somewhere around 47,000 stems that create the grove of trees that keep the root system going.

.........  Les plantes ne sont pas programmées génétiquement pour mourir ?


Non, leur fin est toujours due à des éléments externes : une inondation, un coup de froid, un bûcheron, un incendie... Mais si tout va bien, il n'y a aucune raison pour qu'elles disparaissent. Chez les animaux et les hommes, les gènes s'éteignent par un mécanisme biochimique - la méthylation – qui est à l'origine de la sénescence – le vieillissement. Certains arbres et plantes paraissent échapper à ce processus : avec leur « croissance rythmique » – stoppée en hiver –, ils réactivent leurs gènes « éteints » à compter du printemps, et luttent ainsi contre la sénescence. En outre, à partir d'un arbre originel mort depuis longtemps, des « clones » se forment grâce à des mécanismes de multiplication végétative au niveau du sol, ce qui leur donne une durée de vie illimitée. Il suffit d'aller dans la banlieue de Londres, au jardin botanique de Kew Garden, pour voir une collection d'arbres potentiellement immortels. Les chênes y vivent éloignés les uns des autres au milieu d'immenses pelouses. Leurs branches basses traînent par terre et s'enracinent pour donner de nouveaux arbres, qui à leur tour en donnent d'autres. Si les conditions restent bonnes, pourquoi voulez-vous que ça s'arrête ? Le plus vieil arbre que l'on ait identifié pour l'instant, le houx royal de Tasmanie, a 43 000 ans. Sa graine initiale aurait germé au Pléistocène, au moment de la coexistence entre Neandertal et l'homme moderne. Le premier arbre sorti de la graine est mort depuis longtemps, mais la plante, elle, ne meurt pas, plusieurs centaines de troncs se succèdent sur 1 200 mètres..

Wrong species of Maple leaf on new Canadian bank notes

Wrong species of Maple leaf on new Canadian bank notes | Botany Roundup: Worthy Plant News | Scoop.it

The Bank of Canada blundered by using a Norwegian maple leaf instead of the country's native variety on its new banknotes, plant experts have claimed.

Atlantic Canada Conservation Data Centre botanist Sean Blaney highlighted the difference between the leaf on new \$20, \$50 and \$100 notes and the North American sugar maple.

He said: "It's really hard to deny the image is of a Norway maple."

He said the Norway maple has more lobes - or sections - has a more pointed outline than the sugar maple and the lobe that rises in the centre is shorter than the sugar maple's.

Smallest flowering plant in the world - Wolffia angusta

Smallest flowering plant in the world - Wolffia angusta | Botany Roundup: Worthy Plant News | Scoop.it

Wolffia, commonly referred to as watermeal and misidentified as duckweed, is officially the world’s smallest flower, with each bloom weighing about as much as two grains of sand. It takes about 5,000 of these teeny-tiny flowers to fill a thimble, and they’re amazingly small when seen against the grooves in a human fingerprint. Woffia sometimes grow in colonies that form a dense-looking mat on sheltered waters. The only way to identify the exact species of a wolffia flower is to view it under a microscope.


Each wolffia flower has a single pistil and stamen and produces the world’s smallest fruit, called a utricle. It has no leaves, stem or roots, floating freely in quiet freshwater lakes and marshes. Woffia is highly nutritious, serving as food for fish and waterfowl in nature and occasionally cultivated for use as livestock feed or even human cuisine. It’s eaten as a vegetable in Burma, Laos and Thailand.
