OF BRITISH PLANTS. 181 



PILL-WORT, from its small globular involucres, L. pilula, 

 dim. of pila, a ball, Pilularia globulifera, L. 



PIMPINELL, or PIMPERNELL, Fr. primprenelle, M.Lat, 

 bipennella, from having secondary little pinnae, or feather- 

 like leaflets; in old authors, as Evelyn in his Acetaria, and 

 Lyte, the burnet, of which the Italian proverb says : 

 " L'insalata non e bella Ove non e la Pimpinella." 



Poterium Sanguisorba, L, 

 in modern works more generally 



Pimpinella Saxifraga, L. 



RED-, a plant entirely different from the above, 

 as are the two following species, and in no way agreeing 

 with the name as just explained. Why it was called so, is 

 unknown. Anagallis arvensis, L. 



,, WATER-, Samolus Valerandi, L. 



and in Lyte Veronica Beccabunga, and V. Anagallis, L. 

 YELLOW-, Lysimachia nemorum, L. 



PIN-RUSH, Juncus effusus, L. 



PINE-TREE, L. pinus, a word that J. Grimm considers to 

 be a contraction of picimis, pitchy, and others as related 

 to Skr. pina, fat, L. pinguis, in allusion to its resinous 

 secretion. Isidore says that it was called so " ab acumine 

 foliorum : pinum enim antiqui acutum nominabant " (from 

 the sharp point of its leaves ; for picked was by the ancients 

 called pinum}. The derivation of it from the Celtic pen, 

 a peak, as the usual habitat of these trees, is highly im- 

 probable ; and Wedgwood's, from the English word pin, in 

 respect of its pin-shaped leaves, no less so; for although 

 this word may be an old one in the Germanic languages in 

 the sense of " a peg," it is only within a few centuries that 

 it has been applied to a small familiar article of female 

 dress. Pinus, L. 



GROUND-, from its terebinthinate odour and lowly 

 habit, a translation of its Gr. name ^a/wu-Trm;?, 



Ajuga chamsepitys, L.
