UMBELLIFER^E in 



covered with little bundles of prickles which are hooked and very fine. Flowers 

 yellow, large, sessile, solitary on the edge of the upper joints. Fruit ovoid, dark 

 purplish-red, pulpy and very red when cut, and covered with bundles of very fine

Rocks, walls, and banks, widely spread, May-July. Originally from Mexico, 

 it is often cultivated and frequently naturalized. Here and there other species 

 occur as escapes from gardens. 



UMBELLIFER/E. 



" The subdivision of Umbellifers into genera is much more difficult . . . and 

 the modern genera, founded upon a nice appreciation of minute differences in the 

 fruit and seed, are often very artificial, or still more frequently reduced to single 

 species, and require as complete a revision as the Crucifers and Composites."
