Plants are listed in alphabetical order of their current scientific names. In the case of intergeneric hybrids e.g. X Dactylodenia, the "X" is ignored.
A typical entry looks like this:
*Acaena inermis Hook. f. Spineless Acaena
Raasay: Recording Units:10
Ten kilometre squares: NG 53, 54
First Record: JWHH et al. 1934-36.
Rona: Not known.
A native of New Zealand naturalised from East Suisnish to Inverarish and scattered elsewhere. Mostly along roadsides.
Herb. LANC: KBB 1935 Raasay.
In many cases a diagram showing the 1 km square distribution on Raasay is also shown. These maps have been produced with Alan Morton's DMAP software. On these maps the tidal islands of Fladday and Eilean Tigh have been moved away from Raasay relative to their true positions in order to show the distribution on these islands separately.
Maps are provided for taxa that occur in 4 to approximately 92 of the 100 recording units (see below). There are a few exceptions to this for the sake of inconsistency.
Where appropriate, the status of a taxon as per The Vascular Plant Red Data List for Great Britain is given in purple. This applies to "Nationally Scarce", Endangered", "Vulnerable" or "Near-threatened" species.
Nomenclature follows Stace 2010. For microspecies, Hieracium and Pilosella follow Sell and Murrell, 2006 whilst others follow the 2007 BSBI Plant List. See also The Naming of Plants.
Scientific names are followed by the relevant authority using standard abbreviations.
The following symbols are important:
* Not native to Raasay and Rona in the estimation of the author.
[ ] Records enclosed in square brackets are doubtful or thought to be errors.
“Raasay” is used to include its associated tidal islands of Eilean Fladday and Eilean Tigh. "Rona" includes Garbh Eilean.
For Raasay, Recording Units are 1 km squares. In the case of 1 km squares shared by Raasay and Fladday or Raasay and Eilean Tigh, separate recording units are used for each island. There are 100 recording units. The Recording Unit figures and the 10 km squares refer to records made by SJB from 1983 to 2014, mostly from 1992 to 2004, unless enclosed in brackets (10km squares only) in which case they refer to earlier records that have not been seen since.
There are parts of six 10 km squares on Raasay, NG 53, 54, 55, 63, 64 and 65. Where a plant is known from all six, the entry for ten kilometre squares is shown as "All". Rona is mostly in NG65 but the northernmost part is in NG66.
The remaining layout is:
Details of records where thought important, comments on habitats and how common and widespread the plant is etc.
Herbarium specimens known to the author are referred to as Herb. XYZ: recorder, year, location det. (determiner) as far as known, where XYZ is the standard abbreviation for the herbarium (Kent & Allen, 1984).
Herbarium work has been limited. I have visited BM, E, K, HAMU and SUN, received indirect information on other herbaria and made use of online resources. These include ABD, MANCH and NOT. All herbaria available on the Small British Herbaria Project website on 10 Feb 2006 have been searched.
Place names are generally given in south to north order.
Comments in red are things I need to tidy up! These are now limited to a few dates of first records.
