It is nearly related to Saxifraga bronchialis L. and 5". triaispidata Retz. But 

 it is easily distinguished from the former by its tricuspidate basal leaves with 

 glandular ciliate margins and from the latter by its white flowers. It also differs 

 from the both by having more slender stems bearing a few flowers and also by its 

 glandular-ciliate sepals. 



The plant is named after the name of its collecter, Mr. Shozo Nishida, 

 Assistant of Botany in our College, who has been making a special study of the 

 flora of the Yilbari mountain range for the last four years.
