Obs. — Divstinguished from Lrj. nvrjjijUifolia by the IonL,'er and 

 more narrowly ovate antical lobe, and the smaller postical lolje, 

 smaller cells with thicker walls and anj^les, and lar<^er stipuhs. 



''Lcj.xcrpijUi folia is a smaller plant, colour more rarely yellowish, 

 leaves rounder and with a much longer and more turgid postical 

 lobe, sometimes equalling half the antical." (11. Spruce.) Dr. 

 Carrington was the first to publish any notice of this species as 

 native to our Isles, when he described it as var. thymifolia of Lcj. 

 nerpyUi folia in his '* Irish Cryptogams." Proi. Lindberg afterwards 

 ])ublished it as Lcj. Moorci, but later considered it along with 

 Dr. Spruce identical wdtli Lcj. fava (Sw.), which has a very wide 

 geographical distribution. Plants with perfect perianths are 

 extremely rare.
