I don't know if this qualifies for the culture section, but I don't know where else to put it. Can someone explain the difference between D. limpidium and D. dicheoides and others of that type or point me to a reference? I've looked at the archive of Peter's thread. Woods shows a picture of the flowers, but I was unable to find it in the text (and I was unable to find an index except to the pictures, Mr. Bill indeed!). Lavarack et al don't list it, nor does Baker. Thanks.
