Abstract:

The genus Indigofera Linn. is one of the  largest  genera of papilionatae
of Leguminosae.  It comprises 700 species in the world, of which 80 species and 8 varieties
occur in China.  It was established by C. Linnaeus in 1752 and had been studied by J. Desvaux
(1813), A. P. De Candolle (1825), G. Bentham ex Harvey (1862), G. Bentham et J. D. Ho-
oker (1865), P. Taubert. (1894), P. Ch. Tisseraut (1913), and B. Gillett (1958) etc.
      In the present paper, the taxonomic history is reviewed and the evolutionary trends of
some important morphological characters  are discussed.  According to the plant habit, cha-
racteristics of leaves, shape of fruits and the number of seeds per fruit, Indigofera Linn. from
China are divided into 3 subgenera: Subg. I. Indigofera,  Subg. II.  Sphaeridiophors  Desv.,
Subg. III. Acanthonotus (Benth.) Benth. et Hook. f., in Subg. Indigofera, 14 subsections are
reported. A systematic key to the species is given.
