Re: Dichotomus key "how to"

 

Rodney, please forgive if I am being dense, but if you are looking for a key to use as an example, then you may wish to check Dykes, W.R., The Genus Iris, Cambridge: 1913, which has the advantage of being in the public domain.
 
On page 17 is "Analytical Key to the Subdivsions of the Genus Iris." Then there is, per e.g., on page 19f a key to the subdivision apogons. This won't be the latest opinon on things but it is not entirely without interest.

How to use one. Sorry that wasn't clear.

Rod, 
Are you looking for how to construct a dichotomous key, or how to use one?

Hi All,

We'd like to include a "How to" on dichotomus keys in the next SIGNA. Does anyone have a good one that we could use?
