PLANT DIVERSITY IN FYNBOS: Overview of important fynbos plant families Diagnostic features, systematics, floral adaptations, evolution 12. ERICACEAE: 13. PROTEACEAE: Diagnostic features, distribution, classification, economic uses Field recognition, size, distribution and general information, economic importance 14. RUTACEAE/ POLYGALACEAE: 15. ORDER FABALES: Classification, field recognition of different families, Mimosaceae, Caesalpiniaceae and Fabaceae:Discussion on Polygalaceae vs. Fabaceae.

  6. 16. GERANIACEAE, OXALIDACEAE, SCROPHULARICAE: Field recognition, description, evolution 17. ASTERACEAE, LAMIACEAE: Field recognition, pollination, evolution. Field recognition, description and evolution. 18. GRASSES, SEDGES AND REEDS: ASSIGNMENT 1: A ONE PAGE SUMMARY: Using the Library’s interactive search for journal articles, search 5 relevant journal articles on any topic relating to identification or classification. Write a one page summary summarising the 5 journal articles (note: the summary should be a combined summary and not a summary of the individual articles). ASSIGNMENT 2: ESSAY 1 500 WORDS: Use one of the journal articles and write an essay of about 1 500 words on the topic. Your essay should have an introduction, materials and methods, results, a discussion and a reference list. References should follow the “Council of Science Editors (CSE)” format.
