The synonymy and distinctive characters of the species of this section have been most carefully and — 
accurately worked up by Wenzel Batka, of Prague, from whose * Monographie des Cassien Gruppe Senna,’ 
1866, I have chiefly taken the following abstract, omitting several of the purely pharmaceutical syno- 
nyms, for the details of which I must refer to his work. 1 cannot, however, agree with him in raising the 
group to the rank of a genus: all the characters he gives pass so gradually into the usual Cassia characters 
through séveral species of the Pictæ group (little or not at all known to Batka) that Vogel and others of his 
predecessors, in admitting a section Senna, have included in it more or less of those connecting species ; and 
Vogel finally expressed his opinion that Senna must be given up as a section distinct from Chamesenna.
