A little annual plant allied to Clarkia, found near the 

 Russian colony of Ross in New California, and communicated 

 to the Garden of the Horticultural Society from that of the 

 Emperor at St. Petersburgh in 1836. 



It flowers in about six weeks from the time of germina- 

 tion, and although not to be compared with Clarkia pul- 

 chella in point of beauty, is a neat and by no means weedy 

 plant, and perfectly hardy. 



* From ivxctpic in the sense of agreeable ; in allusion to the appearance of 

 this plant.
