Rubus idaeus .- Frambueso (Chordon) Raspberry.

El frambueso (Rubus idaeus) es una planta que crece particularmente en claros de bosques o prados, en especial donde el fuego o las talas han dejado un espacio abierto para que medre esta colonizadora oportunista. Es de fácil cultivo y tiene tendencia a extenderse a menos que se la mantenga bajo control. Prefiere suelo profundo y ácido pues los calcáreos producen clorosis.
Su fruto es la frambuesa (o frambuesa roja) una polidrupa de sabor fuerte y dulce roja, que sale durante el verano tardío o el otoño temprano. Esta fruta del bosque es parecida a la zarzamora pero más pequeña y blanda.

Rubus idaeus (Raspberry; occasionally as European Raspberry, Framboise, or Red Raspberry to distinguish it from related species) is a species of Rubus, native to Europe and northern Asia.[1][2] A closely related plant in North America, formerly often regarded as a variety Rubus idaeus var. strigosus, is now usually treated as a distinct species Rubus strigosus (American Raspberry).
It is a perennial plant which bears biennial stems ("canes") from the perennial root system. In its first year, a new stem grows vigorously to its full height of 1.5-2.5 m, unbranched, and bearing large pinnate leaves with five or seven leaflets; normally it does not produce any flowers. In its second year, the stem does not grow taller, but produces several side shoots, which bear smaller leaves with three or five leaflets. The flowers are produced in late spring on short racemes on the tips of these side shoots, each flower about 1 cm diameter with five white petals. The fruit is red, edible, sweet but tart-flavoured, produced in summer or early autumn; in botanical terminology, it is not a berry at all, but an aggregate fruit of numerous drupelets around a central core. In raspberry, as in other species of the subgenus Idaeobatus, the drupelets separate from the core when picked, leaving a hollow fruit, whereas in blackberry the drupelets stay attached to the core.

It typically grows in forests, forming open stands under a tree canopy, and denser stands in clearings. In the south of its range (southern Europe, central Asia), it only occurs at high altitudes in mountains.[6] The species name idaeus refers to its occurrence on Mount Ida near Troy in northwest Turkey, where the ancient Greeks were most familiar with it.

Hola Julian,
bella immagine, ottimi POV e composizione con la luce laterale che evidenzia molto bene le caratteristiche del frutto di lampone, la definizione è buona, molto belli i colori e la luce. Interessante questa tua ricerca dei fiori, dei semi e dei piccoli frutti delle varie piante a volte poco conosciute.
TFS.
Maurizio

Julian-

A nice picture and an excellent description of the growth of raspberries (which I see in my back yard here in the US). You should also note that the "hairs" are actually the dried flower parts of the individual drupelets. Your berry shows them as much bigger than for my own berries- probably a difference between the European and North American varieties.

If you want a very different view of a raspberry, including a closer view of the dried flower parts, check out my TN post here (http://www.treknature.com/viewphotos.php?l=3&p=171443). I hope you ate that one after taking its picture!

Bob
