probably the reason that the true plant so long escaped notice. 

 B. bulbocastanum was first observed by the late Rev. W. H. Coleman 

 at Cherry Hinton, near Cambridge, in 1838, and was determined 

 by Mr. H. C. Watson, by comparison with the Linncean herbarium. 



Pimpinella, (Linn.) Burnet-Saxifrage. 

 Linn. CI. v. Ord. ii. 

 Name altered, as Linnaeus informs us, from bipennula, or twice 

 pinnate ; in allusion to the division of the leaves. 



1. P. Saxifraga, (Linn.) common Burnet-Saxifrage. Engl. Bot. 

 t. 407. Reich. Icones. t. 1869. 



Locality. Dry pastures, on banks, and road-sides, in a sandy, 

 gravelly or chalky soil, frequent. P. FL July, September. Area, 1. 

 2. 3. 4. 5. General in all the Districts. Varying in size, and also 

 in the form and division of its leaves. Some writers make several 

 varieties of it, but these are simply occasioned by the different age 

 of the plant, and the greater or lesser expansion of its foliage, 

 according to the soil in which it grows. 



2. P. magna (Linn.) great Burnet-Saxifrage. Engl. Bot. t. 408. 

 Reich. Icones, t. 1868. 



Locality. Woods and hedges, chiefly on a chalky or limestone 

 soil, rare. P. Fl. July, August. Area, 1. * * 4. * 



South Division. 



1. South-east Dktrict, " Hedge-rows near Downton," Dr.Maton. 

 "Nat. Hist. Wilts." 



North Division. 



4. North-west District, " Corsham," Dr. Alexander Prior. This 

 plant has not been observed in either station of late years. Larger 

 in all its parts than the foregoing species, with the leaflets of the 

 upper leaves much broader and less divided. 



Sium, (Linn.) Water- Parsnep. 

 Linn. CI. v. Ord. ii. 

 Name according to Theis, from the word sko, water; from which 

 come the English word sea, and the Greek scio, to shake. 



1. S. angustifolium (Linn.) narrow-leaved Water Parsnep. Engl. 

 Bot. t. 139. Reich. Icones, t. 1878.
