The herbarium is ordered according alphabetically.
All collecting data is documented electronically. At present I use a
HP 690 Jarnado palm top computer to document specimen data in the field.
All locality data is recorded using a Garmin 2 plus GPS. With these facilities,
it is possible to totally eliminate any data back-log, which usually occurs
after a lengthy collecting trip. By these means I am able to give a full
report on plants collected within a day of returning home.
All relevant data concerning the herbarium are kept in relational database
based on Mi-crosoft Access 2000. This facility is regularly used to compile
taxon lists for various projects that I am involved with. The pleasure
of this system is that the information is not fixed.
Herbarium labels are compiled by exporting the relevant specimen data
into a MS Word 2000 mail merge document. The reason for this is multiple.
A database package does not support desktop publishing through its report
generator with the result that labels gener-ated via it look displeasing.
Secondly, where acronyms are used in the database, the words are written
out in full.
The herbarium also houses a collection of approximately 2000 photographic
slides taken mostly of:
1. Plants endemic to the Soutpansberg and there habitat
2. Succulents of the Soutpansberg
