Using the checklist
Arrangement
The arrangement of the checklist is alphabetical by family followed by genus, grouped under Pteridophyta,
Gymnosperms, Monocotyledons and Dicotyledons. All species and synonyms are arranged alphabetically
under genus. Numbering of monocotyledon and dicotyledon genera follows the Englerian system of De
Dalla Torre & Harms (1958), as used by SRGH, with modifications where necessary. This is mostly in
agreement with that given in Arnold & De Wet (1993). However, although arrangement and numbering of
Pteridophyta follows that of the PRECIS system (NBI, Pretoria), nomenclature follows that of Roux (2001).
Author citation abbreviations follow those given in Brummitt & Powell (1992), while authorities for genera
follow Brummitt (1992).
Taxonomy
Accepted names are in bold print while synonyms or previously-used names are in italics.
Flora zambesiaca and Kirkia volumes were used as the major taxonomic references, with nomenclature
checked and clarified using Lebrun & Stork (1991–1997). Where appropriate recent publications are
available, however, these were used instead, including the revised Trees of southern Africa (Coates Palgrave
2002). Hence nomenclature is not necessarily the same as that used by the National Herbarium in Pretoria
or other regional herbaria. Some groups have been reviewed by specialists (Commelinaceae—Bob Faden;
Dracaenaceae—Ratti Takawira; Liliaceae sensu lato—Shakkie Kativu; Orchidaceae—Werner Fibeck;
Poacaeae—Lyn Fish; Asclepiadaceae—David Goyder; Lamiaceae and Verbenaceae—Alan Paton;
Moraceae—John Burrows).
Synonyms
The synonyms for many families are very inadequately treated. It is hoped to add other older or inaccurately
applied names in a later edition. Only synonyms that are recent or known to appear in a number of publications
in use in Zimbabwe, or where the type is from Zimbabwe, are included. They are listed alphabetically under
the appropriate genus. The currently used name follows the equals sign (=), and only refers to usage in
Zimbabwe. Distribution information is included under the current name.
Aliens
All species known or suspected to be fully naturalised in Zimbabwe are included in the list. They are
preceded by an asterisk (*). Species only known from planted or garden specimens were not included.
Distribution
The letters N, W, C, E, and S, following each listed taxon, indicate the known distribution of species within
Zimbabwe as reflected by specimens in SRGH or cited in the literature. The map on page 4 shows these
geographical divisions. Although additional confirmed records are included where available, geographical
coverage is likely to be incomplete. Where the distribution is unknown, we have inserted Distr.? after the
taxon name.
