 leaves, minutely hoary-pubescent. Calyx-segments about 1 line long, obtuse, 

 the 2 outer ones ovate, the B inner usually narrower. Corolla-tube about 2 

 lines long, the lobes rather shorter, papillose inside as well as the throat but 

 not hairy, the right-hand edges overlapping in the bud. Ovary glabjrous. 

 Follicles i to 1ft. long. Seeds about 8 lines long, with a short beak at the

The bark of these trees is a valuable tonic, and largely used in cases of fever. It was first

 white in pedunculate cymes, generally from 6 to 8 at extremities of the 

 branchlets. Peduncles from 1 to 2in. long, angular and hoary pubescent. 

 Cymes trichotomous. Bracts minute, ovate-lanceolate, ciliate. Cs,lyx-segments
