subampliato coronata, compressula, superne alte 5-carinata, demum 
ab apice 4-valvia, valvulis apiculatis, apiculo sublineari cellulas 5 
longo, ¢. 2 (apice ipso ¢. 3) lato. Calyptra paulo brevior pyriformis

Amenta ¢ minuta albida crebra lateralia, f. caulino subduplo breviora, 
incurvula, late ovoidea, compressa; bracteze 3-5-jugee confertee.
