KOEBEBLINIACEAE. 



241 



KOEBERLINIA. All Thorn. 

 (Family Koeberliniaceae). 



Shrubs, horridly spiny by the 

 ascending or horizontally spread- 

 ing terete branchlets which taper 

 somewhat acuminately into very 

 sharp black spines: pith moder- 

 ate, round, continuous. Buds soli- 

 tary, sessile, not evidently scaly, 

 very minute. Leaf-scars lacking, 

 the minute scales which repre- 

 sent the leaves drying on the 

 twig. The branching is some- 

 times alternate and very irregu- 

 lar, and sometimes decussately 

 opposite, as is the disposition of 

 flower buds. 



Koeberlinia presents very much 

 the appearance of some of the 

 spiny Rhamnaceae, but differs 

 from them in technical charac- 

 ters. Only the one species is 

 known. 



Velvety and minutely scabrous. K. spinosa. 



Winter-characters of Idesia polycarpa, of the family Fla- 



courtiaceae, are given by Schneider, f. 84; and Shirasawa, 



283, pi. 13.
