LATIN / BINOMIAL / SCIENTIFIC / BOTANICAL PLANT NAMES 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. The list below shows the meanings of the specific epithets, grouped by meaning.

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...
±	Approximately, tendency towards, not all do, varies, airy-fairy get-out clause!
flore pleno	'with full flower' - Double-flowered. Associated more with cultivated varieties

Map Areas
Myriad	100km x 100km (shown as bolder blue lines on OS maps)  Reqs 2-letter Grid Ref, eg SD
Hectad	10km x 10km (an OS 'tile')  A myriad divided into 100 square areas. There are ~3854 hectads in the British Isles discounting some tiny ones near the coast occupying as little as 1m2. Reqs 2-figure Grid Ref, eg SD15. [You might sometimes come across this notation: SD15:43 (with colon and any number). That number (43) signifies how many plants were recorded in that square]
Quadrant	5km x 5km  (not to be confused with quadrats below). Not an OS grid unit; a hectad divided into 4 square areas.  Reqs 2-fig Grid Ref suffixed by one of these four 2-letter combos: SW, NW, NE, SE. eg. SD15NE
Tetrad	2km x 2km   Not an OS grid unit; a hectad divided into 25 square areas.  Reqs 2-figure Grid Ref plus a 'DINTY' (A-Z, with 'O' missing) letter, eg SD15T
Monad	1km x 1km (aka 'Grid Square')  A hectad divided into 100 square areas.  Reqs 4-figure Grid Ref, eg SD1252 A monad grid is shown below on Roger Goldings combined 'MonaDinty' chart. The monad grid here being the 00 to 100 black numbers.
MonaDinty  (Roger Golding)	Roger Golding writes: "When writing lists of taxa at monad level, I find that it is easy to get confused by the unusual ordering of Letters (DINTY/Tetrad) and Numbers (Monad). So I created this version of the DINTY grid and added the 4 monad numbers for each DINTY letter. I hope others find it helpful too "
Hectare	100m x 100m [abbrev. ha] (aka Centisquare)  A monad divided into 100 square areas.  Reqs 6-figure Grid Ref, eg SD123523
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)  (Cucaera.co.uk)	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.
