Authenticity
Despite popular lore, many clan badges attributed to Scottish clans would be completely impractical for use as a means of identification. Many would be unsuitable, even for a modern clan gathering, let alone a raging clan battle. Also, a number of the plants (and flowers) attributed as clan badges are only available during certain times of year. Even though it is maintained that clan badges were used long before the Scottish crest badges used today, according to a former Lord Lyon King of Arms the oldest symbols used at gatherings were heraldic flags such as the banner, standard and pinsel.
There is much confusion as to why some clans have been attributed more than one clan badge. Several 19th century writers variously attributed plants to clans, many times contradicting each other. It has been claimed by one writer that if a clan gained new lands it may have also acquired that district's "badge" and used it along with their own clan badge. It is clear however, that there are several large groups of clans which share badges and also share a historical connection. The Clan Donald group (clans Macdonald, Macdonald of Clanranald, Macdonell of Glengarry, MacDonald of Keppoch) and clans/septs which have been associated with Clan Donald (like certain MacIntyres and the Macqueens of Skye) all have common heath attributed as their badge. Another large group is the Clan Chattan group (clans Mackintosh, Macpherson, Macgillivray, Macqueen, Macbain, Farquharson, Davidson) which have been attributed red whortleberry (sometimes called cranberry in Scotland), or bearberry, or boxwood. The leaves of these three plants are very similar, and at least one writer has claimed that whatever plant which happened to be available was used. One group, the Siol Alpin group, of clans are said to have claimed or are thought to share a common descent. The Siol Alpin clans (clans Grant, Gregor, MacAulay, Macfie, Macnab, Mackinnon, Macquarrie) are all attributed the clan badge of pine (Scots fir). In some cases, clan badges are derived from the heraldry of clan chiefs. For example, the Farquharsons have pine attributed as a clan badge of theirs (pine also appears on the uniforms of the Invercauld Highlanders). Pine was actually used in the Invercauld Arms as a mark of cadencing to the basic Shaw-Mackintosh Arms.
