Based on information from many Botanical sources..
Extra reading or charts can be found under appendices as indicated. Appendix 1 is of a general nature. Figures are more definitive in the form of drawings
If you come across a botanical term that you are not sure of, please contact me. I might not know the answer but can try to find out
NOTE This is designed for downloading (only 44 pages) plus appendices and figures if you so desire. I find that hard copy is much more useful than checking up on the computer.
