elaeagnus?

Can anyone tell me if elaeagnus multiflora ( goumi ) is the same plant as elaeagnus gris or elaeagnus rastrero. I am seeing conflicting information! There also seems to be two Elaeagnus ebbingei, one has purely green leaves while the other has yellow edges to the leaves known as a 'guilt edge'. Do both variants produce edible fruit?

Many thanks.....

the only references i found for Girs or Rastero, were not in english.
i doubt they are a true species, or even synonym.

A garden hybrid, E. macrophylla x E. pungens or E. x. reflexa.

so, it seems since it is a hybrid, i guess its possible that  one is E. macrophylla with Pugens
and the other is E. macrophylla and E. Reflexa

There is more info here (about 1/2 way down) on ebbingei
i have one, but its still too  small to fruit

i actually have goumi, autumn olive, basterd oleander/So-Shan (E. Latifolia i think)
the latter supposedly has much larger fruit. i have 1 seedling clinging to life ....
