We have indicated the affinity between Scropliularinece and Solanea;. They have also many characters 

 in common with other families having an irregular anisostemonous corolla, and especially with Acan- 

 thacece and Bignoniacece. Acanthacece differ in the aestivation of the corolla, the curved ovules, the 

 processes of the placenta which support them, and the absence of albumen ; Bignoniaccce in the winged 

 exalbuminous seeds, and the ovary girt with a fleshy ring. Many genera belonging to the sub-order 

 Rhinanthidece are root-parasites like Orobanchece (Rhinanthus, Mclampyriim, Pedieularis, Odontites, 

 Euphrnda, Bartsia, Castilkja). 



Scrophularinea; are found in all climates, but most abundantly in temperate regions, and very rarely 

 towards the poles and equator. Their medicinal properties vary greatly, chemical analysis yielding 

 bitter and acrid principles, combined with resinous and volatile substances. Some as Veronica offidnalis, 

 called in France European Tea are tonic, astringent and vulnerary; others are antiscorbutic (V. Becca- 

 bunga). Scrophularia nodosa and aquatica, foetid and nauseous herbs, are resolvents and sudorifics. 



The Large-flowered Snapdragon is acrid and bitter ; it was formerly used as a diuretic. The common 

 Toadflax is supposed to cure jaundice and skin diseases. Eyebright (Euphrasia officinalis) possesses a 

 bitter principle ; a water distilled from it is used in ophthalmia. The seeds of Melampynon pratense 

 are emollients if used externally, but mixed with wheat flour render the latter bitter and poisonous. 



Gratiola officinalis (the Gratia Dei, or Poor Man's Herb) contains a resinous and acrid principle, and is
