34 PICTURE OF ORGANIZED NATURE. 



Some are remarkable for affording volatile oil ; others, 

 for their poisonous qualities : for instance, the Fen- 

 nel, Cummin, Fennel-flower, Hemlock, Water-hem- 

 lock, and, in warmer countries, the Assafcetida (Fe-

 for their root ; as, the Parsnip, Carrot, and Water- 

 Parsnip (Slum sisarum). This Order does not ap- 

 pear to extend beyond the region in the 30th degree. 



12. The Fig- Worts (ScrophnlariaB) are herbaceous 

 at some distance from the snow-line ; remain in the 

 same state in the Temperate Zone ; and become 

 shrubby in the Torrid. The plants, Antirrhinum, of 

 which the A. alpinum inhabits the Alps, the Scrophu- 

 laria, and the Digitalis, belong to this Order. 



13. The Dwarf- rose-bays (Rhododendrd) begin in 

 herbaceous shrubs between the Alpine plants. Aza- 

 lea procumbens and lapponica, according to Wahlen-

 rather the natives of colder than of warmer climates. 

 The most beautiful species, however, are peculiar to 

 warm countries only. 



14. The Order of Rose- like plants (Rosacece) con-

 and admits of several subdivisions. At some di- 

 stance from the snow line it commences with some few
