 to northern India. With these there occur also a few cen-

 Panjab, as for example Ranunculus sceleratus, Convolvulus ar-

Sindh also contains a considerable number of species which 

 have not been met with elsewhere in India, but which are 

 Arabian or Nubian plants. Such are Zygophyllum alburn and
