ORDEB, CVIII. PEDALINEJE. (By C. B. Clarke.) 



Herbs or undershrubs. Leaves opposite, or the upper alternate, entire 

 toothed or divided. Flowers irregular, (in the Old- World species) axillary, 

 solitary or rarely clustered ; pedicels short ; bracts or very small. Calyx 

 deeply 4-5-lobed. Corolla tubular- ventricose ; limb obscurely 2-lipped ; 

 lobes 5, imbricate. Stamens 4, didynamous ; rarely 2. Ovary 2- (sometimes 

 1-) celled; style filiform, stigma shortly 2-lobed; ovules few or many, 

 superposed. Capsule 2- or 3-4-celled, indehiscent or dehiscent. Seeds (in 

 the Indian species) wingless, exalbuminous. Species 40, in the warmer 

 parts of both hemispheres, 



The Indian species are readily distinguished from Bignoniacece by their herbaceous 

 habit and wingless seeds, and from most Scrophularinece by their few or 1-seriate 

 seeds.
