26 THE BOTANICAL MAGAZINE. [Vol. xxvn. No. sic 



Rah. Prov. ISE : Yokkaichi (M. Kawasaki !). 



This species grows on the sandy shore, and it was first 

 figured and described by Yokusai Iixuma in his work " Somo- 

 ku-Dzusetsu " Vol. XII. published in 1856. It is a species 

 stouter-stemmed and larger-flowered than in Arahis Thaliana 

 Lixx. Being annual this differs from A. petrasa Lam., and 



it has a resemblance to a certain form of A. petrogena Kerxer 

 of Hungaria in Europe in its superficial appearance. For the 

 specimens my thanks are due to Mr. Mitsujiro Kawasaki of 

 Yokkaichi, prov. Ise.
