(c) Semitropical or Gulp Strip. 



The Gulf strij), or southern part of the Austroriparian area (col- 

 ored orange on the map), reaches from Texas to southern Florida, 

 covers a narrow strip in southern Georgia, and iDrobably follows the 

 coastal lowlands northward into South Carolina, though not so indi- 

 cated on the map. It has a semitropical climate and is the home of a 

 number of plants and animals not found farther north, among which 

 are the cabbage palmetto, Cuban pine, ground dove, white-tailed kite, 

 Florida barred and screech owls. Chapman's nighthawk, the Florida 

 and boat-tailed grackles, and several small mammals. 



Crops of the Semitropical or Gulf Strip. 



The Gulf strij), though small iu area, is of very great importance 

 from the standpoint of agriculture and horticulture. It is the belt in 

 which rice, sugar cane, and the much-prized Sea Island cotton are pro- 

 duced in greatest quantity and value; and, as a fruit belt, has no 

 competitor except the Lower Sonoran areas of California and Arizona. 

 Bitter oranges, loquats, granadillas, figs, Japanese persimmons, pecan 

 nuts, and numerous varieties of peaches and grapes thrive here, and 

 the citrus fruits (oranges, mandarins, lemons, limes, and shaddocks) 

 are grown successfully in the Avarmer parts, particularly in peninsular 

 Florida, but in the northern parts have suffered severely from frosts. 

 The more important agricultural products are mentioned in the fol- 

 lowing list: 



CITRUS FRUITS. 



Bergamot oranges (P)'^. 



Bitter oranges. 



Lemons (P). 



Belair. Sicily. 



Eureka. Villa Franca. 



Genoa. 



' Tea is grown successfully at Summerville, near Charleston, S. C, and would 

 doubtless thrive in other parts of the Austroriparian belt; but the cost of pick- 

 ing the leaves is so great as to discourage its general cultivation. 



-' The letter (P) indicates that the fruit after which it is placed is cultivated suc- 

 cessfully in peninsular Florida only, except in a few cases where it thrives also 

 in the Mississippi delta below New Orleans.
