Shrubs, with acrid and very tough (jiot aromatic) bark, entire leaves, and 

 perfect Jiowers with a regular and simple colored calyx, bearing usually 

 twice as many stamens as its lobes, free from the 1-celled and 1-ovuled ovary, 

 which forms a berry-like drupe in- fruit, with a single suspended anatro- 

 pous seed. Embryo large ; albumen little or none. 



1. Dirca. Calyx tubular, without spreading lobes. Stamens and style exserted. 



2 Daphne. Calyx-lobes (4) spreading. Stamens included. Style very short or none.

 above the middle, protruded, the alternate ones longer. Style thread-form ; 

 stigma capitate. Drupe oval (reddish). — A much-branched bush, with jointed 

 branchlets, oval-obovate alternate leaves, at length smooth, deciduous, on very 

 short petioles, the bases of which conceal the buds of the next season. Flowers 

 light yellow, preceding the leaves, 3 or 4 in a cluster from a bud of as many 

 dark-hairy scales, forming an involucre, from which soon after proceeds a leafy 

 branch. (Name of uncertain derivation.)
