SCALY BUDS AND NAKED BUDS 



81 



FIG. 79. Alternate leaves of cultivated cherry, with 

 buds in their axils, in October 



living through the colder months of the 

 year, and are also scaly buds. 



In the herbs of temperate climates, and 

 even in shrubs and trees of tropical regions, 

 the buds are often naked; that is, nearly or 

 quite destitute of scaly coverings (Fig. 78). 

 These are best suited for a season or a 

 climate which is both warm and moist. 

 The scales, of whatever sort, with their coat- 

 ings of hair or of resinous material, are of 

 use mainly in protecting buds from sudden 

 changes of temperature or too rapid loss 

 of water. The latter, in climates like that 

 of southern California or the Mediterranean 

 coast, would be during the rainless summer.
