( J. lanceolate ,JF 
BRITISH J UNGERM ANNIJE. 
under the name of lanceolata in English Botany is J. scalaris, a plant which I have observed in 
collections not unfrequently mistaken for it; although the species before us abundantly differs, 
not only in the absence of stipules, but in the large and naked calyx. 
In drying, as is well observed by Dr. Roth, the leaves become crisped ; but they rapidly 
recover their original figure on being immersed in water.
