LVL SCROPHULARINEJE. SCROPHULARIA FAMILY. 

 Herbs, or in some exotic species shrubs, with opposite or 

 alternate leaves and no stipules. Calyx persisting round the 

 fruit, usually with 5 teeth or segments, sometimes fewer. 

 Corolla monopetalous, usually 2-lipped, but sometimes nearly 

 regular, with 4, 5, or rarely more lobes, always overlapping 

 one another in the bud. Stamens usually 2, or 4 in 2 pairs, 

 very rarely 5, inserted in the tube of the corolla. Ovary and 

 capsule divided into 2 cells, with several seeds in each cell. 

 Style simple, usually ending in a 2-cleft stigma. 



A numerous family, widely diffused over the globe, from the Arctic 

 Circle to the tropics, although more abundant in temperate regions than 

 in the extremes of heat or cold, and, generally speaking, well-marked 

 by the 2-lipped or personate corolla, the stamens in pairs, and the several 

 seeds in each cell of the capsule ; but there are some anomalous genera 

 in which these characters are much modified, and two large and natural 

 exotic families, the Bignonia and Acanthus families, are only to be accu- 

 rately distinguished from Scrophularineae by an attentive study of minute 

 characters. To the first of these belong the Bignonias and Tecomas of 

 our hothouses, as well as the Catalpa, often planted in our gardens, and 

 (if taken in its most extended sense) the numerous hothouse Gcsnerias, 

 Gloxinias, Achimenes, &c. The Acanthacece include Justicias, RueUias, 

 and many modern hothouse genera, besides the European Acanthus, 

 which gives its name to the family. 

 Corolla rotate or concave, with a very short tube.
