12 ECONOMIC BOTANY OF ALABAMA 



cypresses. But that has not been demonstrated either. So for the 

 present at least it seems best to treat our red cedars as all one 

 species. 



Its known distribution by regions is as follows : 



lA. Rocky places near Elkmont. Florence, etc. 



IB. Very abundant on limestone on mountain slopes and river cliffs, 

 and scattered in the red valley lands. It seems to be the commonest tree 

 in the region at present, and perhaps always has been. 



IC. Weeden Mountain, Madison Co., and Little Mountain, Colbert Co.; 

 on sandstone. 



2A. On sandstone cliffs, frequent but nowhere abundant. 



2B. On shaly bluffs, etc., mostly along rivers. 



3. Fairly common on limestone outcrops and in flatwoods, especially 

 in Jefferson County. 



4. On high cliffs. Cedar Mountain, Clay County. 



5. Rather rare, mostly in rocky places along the Coosa River and else- 

 where. 



6A. Occasional along roadsides, but rare in perfectly natural places. 

 6C. Old fields, etc., and possibly native in a few places in Autauga 

 and Dallas Counties. 



7. Common on chalk outcrops and river bluffs, especially westward 



8. Bluffs, etc., rare. Montgomery and Barbour Counties, and perhaps 

 in the northern edge of Wilcox. 



lOE. On limestone near Clayton and Lawrenceville, and along the 

 Pea River in Coffee County. 



low. Abundant in northeastern Wilcox County and adjacent Butler, 

 on limestone at the base of the Eocene. A good deal of it was cut oi* 

 long ago by a pencil mill at Greenville. 



n. Frequent on limestone outcrops and bluffs. Said to have been 

 exported from the vicinity of Suggsville about ninety years ago. 



12. Limestone outcrops mostly. Covington, Geneva and Houston Coun- 

 ties. 



13. ,A.long creeks near Brewton. 



15. On shell mounds and shores of estuaries. 



GRAMINEAE (OR POACEAE). Grass Family 



Tnckules about 4.500 species, in all parts of the world. The 

 bamboos and their relatives, native of warm climates, are woody, 

 but the great majority of grasses are herbaceous. Their seeds 

 and foliage furnish more food for man and beast than any other 

 family of ]ilants. Some yield fiber and building material, and 

 many are cultivated for lawns or for ornament. 



ARUNDINARIA, Michaux. Canes and reeds. 



This genus is not very fully understood, partly on account of 

 the scarcity of flowers and seeds, and the number of species in 

 North America may Ije anywhere from one to three or foiu'. In 

 Alabama there seem to be two. or possibly three.
