BUCKINGHAMSHIRE BOTANY. 159 
calities. Possibly those localised ‘* by Colebrooke ” may by ranked 
equally with the plants of either county : but Nos. 4, 5, and 7 are 
certainly to be referred to our county. We may observe that, 
among these eight species, are three which have no claims to 
be considered as indigenous in Bucks—ZJnula Helenium, which now, 
as then, affects “ orchards ;” <Archangelica officinalis, which is, at 
best, but a naturalised plant, and regarding which Gerarde 
expresses some doubt; and Xanthium Strumarium, which no- 
where establishes itself permanently, and seems to have been 
more frequently met with in former times than it is at present. 
Myrica Gale is not now to be met with in Middlesex or Bucks, a 
although Dr. Trimen informs me that it is still abundant in 
Windsor Park. 
John Parkinson, in his ‘ Theatrum Botanicum, or Theater of 
Plants,’ published 1640, gives the following as Buckinghamshire 
plants :— ' 
9. Clematis Fitalba L. (Old Man’s Beard).—‘ In the hedges of 
fields, and by the highwayes side, in Buckinghamshire.” 
10. Anagallis arvensis (carulea) (Blue Pimpernel.) — ‘ At 
Beconsfield in Buckinghamshire.” 
“ Zactuca virosa L.—‘In the borders of fields and by the 
hedges and lanes sides of Buckinghamshire.” 
12. Ceterach oficinarum L. (Scaly Spleenwort).—‘‘ On Beckens- 
field church in Barkeshire.” 
13. Asplenium Ruta-muraria L. (Wall Rue).—*‘ At Beckonsfield 
in Buckinghamshire.” 
It is probable that all of these may be still found in Parkinson’s 
localities. Zactuca virosa is rare with us, but abounds on the 
slopes at White Hill, on the way to Beaconsfield ; I have never 
seen Ceterach on Beaconsfield church, but it is possible that it may 
still remain there in some corner out of sight: as in some of its 
present localities, ¢.g., a wall at Downley—there are but one or 
two very small plants, which might easily escape notice. 
William How’s ‘ Phytologia,’ published in 1650, is interesting 
as being “the first attempt at a Flora of England, all previous 
works having been general systems of botany, including all known
