Also, name and classifications of plants are changing all the time.

You are right in that Volume 1 is from 1983, was probably finished from the writing standpoint in 1982 - so it is nearly 30 years old and lots of name changes since then. I wonder is Susan's New Succulent Spiny Euphorbias from East Africa publication makes reference to any of the name changes, it was published in 1994. Does anyone have the original citing reference for each plant? I believe Tim made reference to it in one of his tags. What do the herbarium species look like?
The comment that cultivated plants lose their morphological similarity with wild plants is very valid in some instances. The one item that is missing as well is that there is a bunch of hybridized plants on the market with invalid names or dubious origins. Euphorbias were even listed in Harry Johnson's early 1939 catalogue for sale and in earlier catalogues as African Cactus. So the naming of the shrew begins.
