This handsome tree differs entirely from the only species, which has hitherto been described, namely Enolcena 

 Wallkhn of Professor DeCandoUe, the founder of the genus. Its leaves and inflorescence are covered with a 

 thin stellate and grey tomentum, whereas in that species they are densely hairy. • Its leaves are entire, and long- 

 acuminate, the flowers disposed in a terminal panicle, and the leaflets of the involucre linear-oblong ; in that species 

 the former are lobed, and the latter axillary, besides being much larger, and furnished with broader and fringed 

 involucres.
