(The plants recognized by landscapers and 

 horticulturists as "rhododendrons" fall into two 

 main categories: lepidote (scaly) and elepidote 

 (nonscaly). Botanically, the lepidotes are found 

 in subgenus Rhododendron and the elepidotes 



in subgenus Hymenanth.es. The leaves of the 

 lepidotes have minute surface^ scales and are 

 generally smaller than those of the elepidotes. 

 The lepidotes include, among others, species 

 native to the southeastern United States (for 

 example, R. minus), to subarctic regions (for 

 example, JR. lapponicum), and to the Alps and 

 Pyrenees (for example, R. ferrugineum) . Many 

 of the subarctic and alpine species and their 

 hybrids do not thrive in the summer heat of the 

 southeastern United States. 



The elepidotes (R. maximum and R. 

 catawbiense, for example) are species generally 

 recognized by the layperson as rhododendrons. 

 Some of the elepidotes have leaves that are 

 glabrous (without hairs), while others have leaves 

 with indumentum (matted branched hairs) on 

 the lower surface. Azaleas are also members of 

 the genus Rhododendron. Approximately 15 

 deciduous species are native in the eastern 

 United States, and a number of these have been 

 crossed with Japanese, Chinese, and east- 

 European species to develop showy hybrids (for 

 example, the Ghent, Knap Hill, Exbury, and Ham 

 hybrids). The evergreen azaleas are of east-Asian 

 origin. Their degree of leaf retention may vary 

 with severity of the climate.)
