Stachyuraceae. 



Stachyurus. 

 ( Family Stachyuraceae ) . 



Shrubs, with some inflorescence- 

 branches developed the first year: 

 deciduous. Twigs glabrous, mod- 

 erate, rounded: pith relatively 

 large, round, continuous, white. 

 Buds rather small, sessile, soli- 

 tary, ovoid, appressed, with 2 

 more or less pointed scales. Leaf- 

 scars alternate, narrowly cres- 

 cent-shaped, somewhat raised, 

 rather small: bundle-traces 3: sti- 

 pule-scars short. 



Winter-character references to 

 Stachyurus praecox: Schneider, 

 f. 87; Shirasawa, 242, pi. 3. 



The family Stachyuraceae in- 

 cludes only the one genus, Stachy- 

 urus, and was known until re- 

 cently only through one species 

 from Japan and one from the 

 Himalayan region. Of recent 

 years, several Chinese species have been discovered. Those 

 that have been brought into cultivation, like Forsythia, some 

 of the bush honeysuckles, and the Asiatic magnolias, are 

 prized because they flower early, before their foliage expands. 

 Twigs and buds rather glossy brown: Japan. S. praecox. 



Twigs green or dull brown: China, S. chinensis.
