Had Miss McGhie lived in our "interesting" times, she would have been
a near neighbour of mine. Alas, though, she cannot now defend her reputation
from the slight on her botanical worth, printed in the last issue of the
Shropshire Botanical Society's Newsletter. May I therefore leap to the
lady's defence, and beat off an attack impugning her honour?
A site whose habitat is hostile to a particular suite of species nowadays
might have been eminently suitable for them many years ago. But many naturalists
underestimate the great extent to which secular ecological successions
alter habitats and the identities of species living at particular locations,
even during brief periods of only a few years. This fault is apparent
in the article discussing Miss McGhie's botanical records.
Juniper (Juniperus communis) was once quite common on the
hilly brakes of Deerfold Forest, about eight miles south-west of Ludlow
in north-west Herefordshire. Thus, the Hereford Times of June 5th,
1869, P.10, quotes a paper delivered by Henry Graves Bull: 'Common Juniper....
grows very freely on the eastern side of the Forest [i.e. west of Aymestrey].'
W.H. Purchas also reported Juniper from the Vinnals on Bringewood Chase
just west of Ludlow, presumably around the middle of the 19th century
before he left Herefordshire to live in Gloucestershire and Staffordshire.
And Sinker et al. report its rediscovery on Bringewood late in
the 20th century. I therefore think it reasonable for Juniper to have
also existed - if only as isolated plants - on the hillsides of south
Shropshire, for instance at Caynham Camp. Presumably Juniper declined
and approached extinction in north Herefordshire and south Shropshire
during the 19th century, as hillsides were cleared of scrub for pasture.
Wood Stitchwort (Stellaria nemorum) is easy to overlook
unless you've got your eye in for it, and Miss McGhie may have been more
observant than we latterday worthies. It grows in woodland on Wigmore
Rolls only six miles west-south-west of Ludlow, so as with Juniper, the
plant may have occurred (and perhaps still persists unnoticed) elsewhere
in woods about Ludlow.
Pale St John's-wort (Hypericum montanum) and Spring
Cinquefoil (Potentilla neumanniana) like abandoned quarries
where calcareous rock and soil yet remain fully insolated, succumbing
once trees and shrubs cast sufficient shade. Thus, they become victims
of a natural ecological succession, in contrast to the human influence
which did for Juniper. Both species live at Nash Quarry near Presteigne,
13 miles south-west of Ludlow, and Pale St John's-wort also persists in
an abandoned quarry near Leintwardine, six miles west of Ludlow. Moreover,
the landscape of south Shropshire is littered with small quarries for
building and road-stone, which had only recently been abandoned in McGhie's
time in the first half of the 19th century. Quarries with calcareous rock
and soil - such as those on Wenlock Edge, its southern extensions around
Craven Arms and Stokesay, and The Novers on the southern flank of Titterstone
Clee Hill - would have been ideal for the Hypericum and Potentilla
until more robust woody plants succeeded them.
Historical evidence, botanical probability and secular ecological succession
therefore suggest that many of Miss McGhie's more surprising records stand
every chance of being correct, and that it is over-harsh to impugn her
botanical reliability. It is more reasonable to conclude there is not
quite enough evidence to prove her records wrong than not enough to prove
they were right. True, she would have been botanically isolated in Ludlow,
perhaps only with Withering's Botanical Arrangement and John Galliers
of Stapleton and Leintwardine to assist her with identifying puzzling
plants. Galliers was a fellow-member of the Ludlow Natural History Society
in the 1830's, and must have come to Ludlow fairly frequently. On the
other hand, I doubt if McGhie met Joseph Babington, for he had left the
district by 1817 when Miss McGhie arrived (Shrewsbury Chronicle,
June 28th, 1844). However, I do not think that Miss McGhie was a botanical
novice by the time she came to Ludlow. Au contraire, she probably
possessed more botanical nous than most. Her father, Robert McGhie was
living in the (then) very fashionable Russell Place, Fitzroy Square, London
before he died in 1806 (Gentleman's Magazine, 1806, 76: 590), and
as a maiden lady Mary presumably lived there too, where she very probably
attended soirées at their neighbours the Marcets. Jane Marcet was a popular
botanical Anglo-Swiss authoress (Shteir, A.B., 1996, Cultivating Women,
Cultivating Science, John Hopkins University Press, Page 100), whose
parties would have brought Miss McGhie into contact with a wider botanical
world. Moreover, Miss McGhie may well have first widened her botanical
outlook while visiting or living in Jamaica, where her father had owned
an estate in the late 18th century, and Maryland, U.S.A., where her brother
Thomas lived before coming to Woodhampton near Little Hereford. Miss McGhie
may therefore have had a much broader and more varied botanical background
than any of her contemporaries in Shropshire.
Added to historical evidence for the creation of and subsequent changes
in habitats, and the known occurrence of uncommon plants in those habitats
around Ludlow, I conclude that Mary McGhie's records are more likely to
have been right than wrong, and recommend that we regard them in that
light.
Today, with so many better floras and more informed botanical colleagues
to call upon for guidance, we latterday botanists still make mistakes
in identification. Yea, even the best of us have bad days and blind spots.
Miss McGhie, too, will, of course, have been human.
