A TRIBE OF SCROPHULARIACE.£. 
The plants of this tribe are readily dis- —— — 
tinguished from Rhinanthee by the upper — — 
lobes of the corolla not galeate, from all — 
others by the anthers and stigmate. They 
nearly all, like the Rhinanthee and many 
Veronicee, blacken in drying. x 
In their geographical distribution the 
several species are more confined than in - 
most genera, having, as a whole, so wide a 
geographical range, owing perhaps to the 
same cause which makes so very beautiful 
a group so rare in our gardens, the difficulty 
of preserving the seeds. Of the eight 
well-known genera of true Gerardiee, the 
greater proportion are American, but three 
genera have representatives in tropical and - 
South Africa, and two in East India. No 
species are common to the Old and New 
World, nor even to Africa and Asia, orto 
North and South America; but every ge- — — 
nus (unless Sopubia be considered as one 
has some American species. There are 
none known in Europe, North Africa, North 
Asia, Australia, or Polynesia. The genus 
Centranthera, which is somewhat anoma- 
lous, extends from East India to North
