[Mediawiki-l] template

[wiwo wowi]

I have seen in the spanish wikipedia, in the entry "calamar", that there is
some kind of template on the right-hand side.

I have some plants and I would like to create a wiki for them to my personal
use. I would like you tell me how could I create a similar template as the
one displayed in the above wikipedia entry with the fields I want.
