St. Joseph's I.; Sitting Rabbit; S.Mich. (Wright). The last two species 

 of gooseberry were seen at Sitting Rabbit growing within three 

 feet of each other, in a beach composed of fragments of limestone, 

 very prolific. Though the former species is generally cultivated, 

 the latteris preferable, the fruit being larger, with a pleasant tart 

 in place of the fiat sweetness of the former, and the branches less 

 thorny. Its branches are spreading or procumbent; those of the 

 former erect and rigid. By this difference they are easily distin- 

 guished at a distance.
