Species AccountsFor each species, the current scientific and common names are given, followed by its status in thecounty. Then there is a description of its recorded history, generally starting with the oldest knownsites and working through to the most recent. Notes are given on the distribution or status beyondShropshire where this is useful but, given the number of Atlases and guides now available, noattempt has been made to cover this subject comprehensively. Almost all records are given in full,with the site name (where there have been changes the modern name is normally used), year andrecorder (often just the surname for the more prolific botanists). Unconfirmed and erroneousrecords are often given in the text but do not appear on the maps. If a species is thought not to havebeen correctly recorded in the county, the name is enclosed by square brackets. Species with morethan a few sites are mapped using tetrad dots, with open circles for pre-1995 records and blackdots for 1995 onwards.Aconitum napellus L.Monk’s-hoodArchaeophyte. Scarce.Monk’s-hood has been cultivated in Britain asa medicinal herb for thousands of years. It isalso now grown as an ornamental, and it is acommon and widespread garden escapethroughout Britain, being recorded in over 600hectads in the New Atlas. There are thought tobe three taxa: a putative native subspeciesA. napellus ssp. napellus, which occursnaturally only in western England and southernWales; an introduced European subspeciesA. napellus ssp. vulgare, which is widespread;and a garden hybrid, A. x cammarum, which isthought to be under-recorded. All three arewidely cultivated.Edward Whitehead (1789-1827) is widelycredited (e.g. Clarke 1900, Desmond 1994)with the discovery of ‘truly wild’ Monk’s-hoodin Britain, which he found growing along theLedwyche Brook at the base of the Iron Agehill fort of Caynham Camp (SO5473) in 1819;but it seems that Edward Williams and JosephBabington had both recorded it there some 20years earlier, and Leighton (1841) dismissed itas an introduction. This debate is still quiteunresolved, and there is a case for it to beviewed as a native, archaeophyte or neophyte.Joseph Babington’s comment (in Plymley,1803) is delicately worded: ‘This plant, whichis now, I believe, allowed to be indigenous,grows in an apparently wild state, in someplaces within a few miles of Ludlow.’Whatever its status, it is still present alongsome of the tributaries of the Teme. Forinstance, John Akeroyd has recorded it as20native along the Seifton Brook in SeiftonBache (SO4784, 1989). Elsewhere in thecounty it is almost certainly a garden escape. Itis difficult to be certain how many putativelynative populations there may be, but it is quitepossibly fewer than ten.43210987Aconitum napellus2 3 4 5 6 7 8Agrostemma githago L.CorncockleArchaeophyte. Rare.Corncockle was once a serious agriculturalpest, contaminating cereal crops with its bitterseeds. In 1841 Leighton considered it toocommon to record, so the first localised recordof it in the county was in 1849 (in cornfields atWhitchurch, SJ5441, H. Sandford). It seems tohave been eliminated from crops in the late 19 thcentury, as most of the more recent records forit are as a casual; for instance George PottsRare Plants of Shropshire
