Species Nomenclature Map Areas

The purpose of the Latin or botanical name of plants is to provide some information about a particular plant that distinguishes it from other plants.

The first part of the binomial name always names the Genus to which the plant belongs (although this can change from time to time dependent upon the whim of taxonomists). The genus name is also descriptive of that particular genus, describing some aspect of it.

The second part of the binomial name is the species name; the adjective applied to the plant, called the specific epithet, which is often helpful in describing the plant. The specific epithet may tell us the colour of the flowers, the height of the plant, whether the leaves are long and thin or short and fat, whether the plant is prickly, where it comes from (which might give us a clue as to how hardy it is), what sort of conditions it occurs in naturally, how big it is, whether it's a climber or whether it's creeping, whether it's deciduous, an annual or perennial, has a bulb, is edible - or whatever else the person who first found and named it (either correctly or mistakenly) thought most remarkable, noteworthy and unique about it.

Like many other languages, Latin assigns genders to all its nouns, and the adjectives have to be compatible with the gender of the noun they describe. In plant names, therefore, those genera which are deemed masculine will end with -us, those that are feminine will terminate with -a, and those that are neuter will end in -um (plus some others with alternative endings), but all have much the same meaning. The gender of the specific epithet must be the the same as that of the species name. But the gender of the name does not refer to the sexual gender of the plant (most plants are hermaphroditic aka bisexual anyway), it refers to some abstruse and obscure concept invented by ancient civilisations such as Romans and other antiquities.  Grammatical Gender. Your Author wonders if some maverick taxonomist has either purposefully or unknowingly assigned different genders to any plant binomial names?

However, not all binomial names are in Latin. Some are in Greek, or a binomial combination of both Latin and Greek. Some are invented latinesque-type names which were never a part of the original Latin language, or are even a bastardised admixture of latin and greek forms melded into one word.

 Species Nomenclature  
 sens. lat. (or s.l.) sensu lato in the broadest sense : denotes 'no taxon'; it is used to mean that it encompasses all taxon of the species.
 senso stricto (or s.s.)  in the strictest sense : used to denote that it applies to only one taxon, e.g. Polypodium vulgare ss. (rather than Polypodium vulgare sl.)
 agg. aggregate: a group of closely related species or sub-species.
 sp.  Species (singular).
 spp.  Species (plural)
 subsp. (or ssp.)  A sub-species of the taxonomic rank having various small differences, but which can interbreed with each other
 subspp. (or sspp.)  ssp. (plural): A number of sub-species
 microsp. (or microssp.)  A microspecies of the taxonomic rank having a continuous spectrum of various small differences often perpetuated by apomixis (reproduction without fertilization) - a genetic swarm, as in Taraxacum (Dandelion) microspp. and Rubus (Bramble) microspp.
 var.  A differing variety of the species in question, a naturally occurring and distinct form of a plant, but of lower rank than is a sub-species.
 forma (or f.)  A form of lower rank than that of variety, used mainly for colour forms; only occasionally for single-difference variations.
 infraspecies  Of lower rank than that of species, in rank order: species, sub-species, variety, form.
 sect. or sectio  A sub-genus, an intermediate between a genus and a species.
 +  A chimera created by a grafting process, e.g. Aesculus + domestica (Dallimore's Chestnut), being a fusion between Horse-Chestnut and Yellow Buckeye
 cf.  Equates approximately to 'Compares favourably to'. Used when the species cannot be identified with certainty using the available evidence. [Not to be confused with Cf - the radioactive element Californium]
 cv.  Cultivar. 'cultivated variety, cv.' or man-made hybrid. The cultivar common-name is often shown between single quotes, e.g. Mallus domestica cv. 'Granny Smith'
 ct. / CT  Chemotype (not recognised as a part of the species name) - a chemotype is where certain species of otherwise anatomically identical plants can produce differing secondary metabolites (chemicals)
 nom. nud.  Latin: Nomen nudum = naked name). A name which is not currently accepted
 nom. illeg.  Nomen illegitimum - an illegitimate name
 nom. superfl.  Nomen superfluum - a superfluous name
 syn.  Synonym - a mis-applied name from another Author
 auct. brit  Auctorum Brit. - a name mis-used by British authors
 auct. non  Auctorum non - a previously used name for a species
<Genus Name>  a × b  Denotes a hybrid between species 'a' and species 'b'. e.g Epilobium lanceolatum x tetragonum
<Genus Name> × c  Denotes it is the 'common-name' of the hybrid (between two un-specified plants a and b). e.g. Epilobium x fallacinum
X <Genus Name> b  The large 'X' denotes that it is an inter-genera hybrid. Sometimes alternately shown as '<Genus Name A> X <Genus Name B> C' e,g. Secale X Triticum. The mere presence of Intergenera Hybrids implies that the taxonomy is wrong somewhere...

 Quadrat The area within a small sub-divided frame of any size but usually 0.5m x 0.5m or 1m x 1m which is placed on the ground (usually arbitrarily) for recording species
 Transect Walking in a set line (marked by rope, not necessarily straight) to record species. Because how many plants you recognise might depend on the resolution of your eyes the plants have to be touching the rope to count. Use a very hairy or very thick rope...
 The boundaries of most of the above areas are tied (quantised) to the UK Ordnance Survey grid, and are not located at arbitrary geographic locations (as far as their use in species recording is concerned - e.g. farmers may differ re hectares of arbitrary shape).
 Vice County Map (simple)
 Botanists cut up the UK into Vice Counties, where the boundaries do not constantly change at the whim of politicians or electioneers. Most are bounded by natural obstacles in the landscape such as rivers, hence the squiggly lines.
 Vice County Map (scalable)


 This Vice County map is scalable and uses Ordnance Survey maps which includes mountains, valleys and contours. Unfortunately if used on a mobile phone it doesn't use the mobiles internal GPS for your position. Your Author has pre-selected the modern OS map as background for the reader, but other maps are available by using the options menu near top right.
