Re: How many Sansevieria species?

     Hello Steve and all,

              Very much apreciated your answer Steve. I will
     check out the archive.
               We are extremely time tight for the next 7-9 weeks. But
      may drop in at times.
                Please take good care everyone and do not forget to
      watch out for all of our little  grumbling.

             Have A Happy Halloween all.
