I would add that Hihgland Horn

As to the thorns, my own experience is they go deep and nearly always go bad

Prunus spinosa L.
Blackthorn, Sloe Tree
This species forms a very spiny shrub (Polunin 1969) with a long-standing reputation for inflicting thorn injuries that take longer than expected to heal: "The thorns have something of a poisonous nature in the autumn" (Withering 1787); "From some effects which I have repeatedly observed to follow the ***** of the thorns, I have reason to believe there is something poisonous in them
" (Withering 1801).
Buhr (1960) reported that thorn injuries of the hands from this plant in 10 patients, most of whom were agricultural workers, required nearly four times longer outpatient treatment than did thorn injuries from hawthorn (Crataegus monogyna Jacq.) or from gooseberry (Ribes uva-crispa L., fam. Grossulariaceae).
Uteau & Bouget (1928) held that the fly-infested putrefying bodies of birds and small animals spitted on the thorns by shrikes accounted for the inflammation that occurs after blackthorn ******. These authors also noted that they had seen two cases of thorn-induced tetanus. However, Buhr (1960) recovered no unusual bacteria or other pathogens either from his patients or from cultures of blackthorns obtained from hedges. However, he did note also that one of his 10 patients developed tetanus of moderate severity. Other case reports include a horseman who unknowingly sustained a deeply penetrating thorn injury whilst leaping a hedge and who became increasingly debilitated until the thorn was eventually discovered 6 years later and removed (Wardell 1851); a 9-year-old schoolboy in whom the broken tip of a thorn produced a profuse foreign body reaction (Latham 1960); and a 61-year-old housewife who developed dyspnoea and a generalised vesicular rash, infected in places, after scratching her arm on a blackthorn (Cashmore 1960). It would appear that the tip of the rough long brittle thorn of the blackthorn snaps off more readily in the skin than does the short needle-sharp point of hawthorn.
Dermatitis from sloes is noted under Prunus domestica.
