OY BRITISH PLANTS. 169 



ONE-BERRY, from its one central fruit, the trulove, 



Paris quadrifolia, L. 



ONE-BLADE, from its barren stalk having only one leaf. 

 Its Latin specific name implying " two-leaved " refers to 

 the flowering stalk. Maianthemum bifolium, DC. 



ONION, Fr. oignon, in a Wycliffite version of Num. xi. 5, 

 uniowns, from L. unio, some species of it mentioned by 

 Columella, Allium Cepa, L. 



WELSH-, not from Wales, but the G. wdlsch, 

 foreign, the plant having been introduced through Ger- 

 many from Siberia, Allium fistulosum, L. 



ORACH, formerly Arach, in Pr. Pm. Arage, in MS. Harl. 

 978, Arasches, Fr. arroche, a word that Menage and Diez 

 derive from L. atriplice. Its Gr. name %puo-o\a%ai/oz/, 

 golden herb, suggests a more probable explanation of it in 

 a presumed M.Lat. aurago, formed from aurum, gold, by 

 the addition to it of ago, wort, as in plantago, lappago, 

 solidago, etc., and this word aurago would become in French 

 arroche, as borago bourroche. At the same time its use in 

 the cure of jaundice, aurugo, may have fixed upon the 

 plant the name of the disease. 



" Atriplicem tritam cum nitro, melle, et aceto, 

 Dicunt appositam calidam sedare podagram : 

 Ictericis dicitque Galenus toilers morbum 

 Illius semen cum vino srepius haustum." 



Macer, c. xxviii. 1. 7.

 ORCHARD-GRASS, from its growing in orchards under the 

 drip of trees, Dactylis glomerata, L.

 by Scheler to be a transposition of rochelle, a small rock, 



Eoccella tinctoria, Ag.
