 roots, simple, nearly straight, furrowed, otherwise smooth and 

 rather lucid, marked with the circular scars of the fallen

 young well decorated Avith leaves, when old leafless, and 

 then floriferous. Leaves alternate, sessile, rather remote, nar- 

 row lanceolar, obtuse, finely ribbed; from four to five inches 

 long, by one broad. Racemes lateral, from the old leafless 

 stems or branches:, diverging, flexuose, with one large pale.
