In my paper above cited, I mention that the present plant agrees quite

 f. Fl. Brit. lud. I. p. 13<i, and is also very like the European A. erenosa, 

 SCOP. Although I did not, at that time, see ANDERSON'S specimen, I 

 thought that the plant must be identical with A. tar fixacif alia. While 

 studying here at Kew, I have compared it with the type of the same 

 species, and have found that they are quite different. The Formosan plant 

 is distinguishable from the Indian in having nearly erect and stouter pods,
