A few documents received from Robert Pitman back in 2002? regarding Yucca filamentosa/flaccida/concava/smalliana. Do others agree with this?

Hello Tim

Thanks for the documents containing the descriptions.
I think that significant deviations in filamentosa-flaccida complex there.
What has led in the past to the fact that the species filamentosa, flaccida, concava, smalliana were formed.
I am now of the opinion that can be in the south and in the north occurring flaccida numerous local transitional forms because of the large distribution area between the south filamentosa occurring,
which may be described differently (filamentosa, concava, smalliana, flaccida).

Since we often have plants without origin here, I prefer to talk about filamentosa/flaccida-complex und a categorization in types.

Also Remember the report by Rentsch and Leebens-Mack.

Have a nice weekend
Thomas

Hello,

I tried many years ago ((January 2001) to make my own key to this name-mess : http://www.bennyskaktus.dk/YfilaKey.htm

At the time of writing, I had hoped that all my young plants grown from seeds collected in habitat, in time would have grown to maturity, but unfortunately has it proved to be difficult to grow them up here in northern Denmark. I really would have liked, to be able to compare the different plants originating from the different locations with each other, when they were grown in the garden of ours.

I will now read the material of Robert Pitman and compare it with my own "key", maybe we are in the same track?.

Have a nice day

Benny
