Since the matter has arisen for walnuts, I will try to approach the specific nature of walnut.
The essence is the what of the substance.
is absolutely impossible for man in this world can reach all making a walnut tree is a walnut tree and nothing else.
Being aware of the limitations of our finite understanding, but relied on the intelligibility of living beings, I will try to enumerate a few essential notes of nuts.
Walnut is a living being with a vegetative soul that allows you to feed, grow, repair and reproduce.
The walnut is a large tree, after the first year, none of your buds maintains dominance, so configured with multiple trunks of equal importance to build a well rounded cup.
The walnut is a good shade tree that has compound leaves with large leaflets, is deciduous.
The walnut has unisexual flowers, male are hanging catkins and the female separate clusters of two or three, with showy stigmas.
The walnut is a drupe fruit, the shell adopts an ellipsoidal shape, opens on two flaps. The fruit is oily, with a thin skin gently with a bitter and reminiscent involutions brain lobes.

The bark is smooth on young branches, and very rough over the years. The wood is heavy, and noble, very appreciated in carpentry.
Walnut is incompatible with the garlic, the nearby presence may cause his death.
all that together and other aspects unknown to me, are the essential notes of nuts, they all belong to the same species, because everyone responds to the specific nature.
That essence can manifest in many specific morphologies, depending mainly on soil conditions and climate.
could be included in essence to have pairs of chromosomes X, but could not include the nucleotide sequence because these sequences indicate the management of the amino acids of proteins with which it has to be built walnut and perform their vital functions and it is clear that not all walnut clones, there are many viable sequences for each protein using walnut, so setting one of them, does not define the specific nature of the walnut, which is common to all.
On the other hand, there are requirements and other incidental features, such as finding a nut that opens into three leaflets, is something accidental, not essential.
If any of the qualities we have mentioned, it is not essential, it is common to all the walnuts, then it is not an essential feature, but accidental.
If an evolutionist, I would that a species is something more definite and concrete, if you want to distinguish two species because there are walnut with paripinnate leaves and other leaves imparipinnate, and argues that blind chance has produced a mutation that caused the morphological change (which on the other hand can not prove) you have to accept if you want to be consistent, that the evolution does not serve any purpose but that is random, within a time, can produce a new mutation that stir the change, so what he Speech is variability within a species, if you will, over time, even in the case that at this particular time, and how far can one ensure, these two walnut trees that differ in specific detail not cross (which also rarely happens), because if the mechanism is that game randomness within a time, a new mutation may make it cross again.
I fully understand that the botanists who are dedicated to the taxonomy, looking for maximum accuracy and morphological or genetic distinction, but I'm talking about something else, a living being, they only study the one hand, the rest, unfortunately , have lost sight of.
