First observed in Ireland by Mr. Shuttleworth, in wet bogs near 

 Rynvile, Cunnamara, where it has since been found by Mr. Babington

 Hill of Howth, in August 1835, where it had been mistaken for S. se- 

 taceus. (3. was found near Cork by the late Doctor Sealy. Fl. July. 

 !. a. has since been observed in several other parts of the country. 

 Mr. Moore finds it more abundant in the County of Deny than the 

 other species, and it appears to be the most common of the two in Ire- 

 land. In habit much resembling the last, but readily distinguished by 

 its peculiar fruit.
