Helix wines also have a distinctive new label, featuring an image of a snail.
Helix, the genus name for the Burgundian snail, is the creme de la creme of “escargot.” As the back label explains, the Tucker family has been wheat farming in and around Walla Walla since the late 1800’s.
With their granddad’s approval, they sold the Helix farm in order to build a new winery and create a second label.

A double helix typically consists geometrically of two congruent helixes with the same axis, differing by a translation along the axis, which may or may not be half-way.
A conic helix may be defined as a spiral on a conic surface, with the distance to the apex an exponential function of the angle indicating direction from the axis.

 Canary Islands Laurel Forest
The trees with laurel-like leaves in the Canary Islands must be regarded as a sort of living Paleo-flora, relict of a kind of sub-tropical humid vegetation which, until the end of the Tertiary period (late Miocene and early Pliocene), could be found in large parts of South Europe and North Africa.
The whitish flowers have a hint of brown but they are very showy for their calyx which is covered by the same white tomentum as the leaves; they are grouped in a close inflorescence, spike-like and sometimes branched at the base.
As in the case of Asplenium, this is a genus of fern with cosmopolitan range of which A. capillus-veneris is surely the most common representative.

 Apple snail (Ampullariidae) genera and species.
But according to Dall (1904) his work was published anonymous, was not for sale, didn't bear the name of the author or the name of the publisher and is invalid under the rules of nomenclature.
This genus description did fulfil the requirements of the nomenclature rules, although it was later restricted to the Old World Ampullariidae, with the exception of the West African genera Saulea (Gray, 1867) and Afropomus (Pilsbry and Bequaert, 1927).
However, Dall (1904) designated Helix ampullacea as the type species of Pila rendering Ampullaria Lamarck, 1799 a junior objective synonym of Pila Röding, 1798, despite his designation of Nerita urceus Müller, 1774 as the type of Ampullaria.
