UNIQUE NUMBER: 649867
DUE DATE: 24 April 2020
, Question 1
1.1) A good classification system should allow one to identify an unknown
plant successfully as part of a family or group – if you cannot identify it
then it means it is a poor system for the specific circumstances.
Classification systems are based on many characters and has a predictive
value. This means, if one species of a genus has a character that was not
known when the genus was described, it is quite possible that other
species in the genus have the same character. Natural classification
systems usually have a very high predictive value when a taxon assigned
to a family, because they follow a multi-disciplinary approach.
1.2) Three ways in which disjunct distribution pattern could develop:
❖ There may be long-distance distribution of taxa from one area to
another with no suitable habitat in between, for example:
colonisation of islands.
❖ Taxa may formerly have had a broad continuous distribution, but all
that may remain are relicts, for example: the Protea spp on the high
mountains in Central Africa.
❖ Taxa may have originated independently in different areas.
1.3) Data is collected from nature, the labs, gardens, herbariums, the
libraries and computers and then it is interpreted by modern or
traditional ways.
Traditional approach
❖ Collection of data is derived from nature, libraries and multiple
herbaria
❖ Interpretations of the data collected are then based on theory,
descriptions and observations
Modern approach
❖ collection of data is derived from botanical gardens, laboratory
and computers
❖ Interpretation of the data collected are based on methods that
are experimental, analytical and synthetically oriented
