The leathery, evergreen leaves are elliptic to lanceolate, 12 to 25 mm long, and 

 less than 12 mm wide. They are somewhat resinous and glabrous above, white hairy 

 beneath, with entire revolute margins, and a prominent midrib. 



The plumose style on the fruit is 50 to 75 mm long. The flowering period extends 

 from May to June, and fruit ripens from May to August. Curl leaf mountain mahogany 

 averages 51,865 cleaned seeds per pound (114/g) (Plummer and others 1968). 



Hybridization: Natural hybrids (fig. 12 and 13) between true mountain mahogany 

 {C . montanus) and littleleaf mountain mahogany have been observed in most places where 

 their respective ranges overlap.
