EUPHORBIACEAE. 



175 



ANDRACHNE. 

 ( Family Euphorbiaceae ) . 



Small shrubs: deciduous. Twigs 

 5-angled or terete; the youngest 

 very slender, the older with some- 

 what flaking bark: pith small, 

 rounded, continuous. Buds small, 

 collaterally multiple, with several 

 ciliate scales, the axils often oc- 

 cupied by pedicel-scars. Leaf- 

 scars alternate, minute, half- 

 round, low: bundle-trace 1: sti- 

 pules more or less persistent at 

 the side. 



Neither Andrachne nor Securi- 

 nega is of much merit, but the 

 rarity of woody Euphorbiaceae 

 outside of the tropics make them 

 a little puzzling when they are 

 encountered. Winter-characters of 

 Securinega ramiflora are given by 

 Schneider, f. 125. As typical of 

 many anatomical studies to which 



reference is not made in this book, may be cited a paper on 



the phyllanthoid Euphorbiaceae by Rothdauscher, published 



in volume 68 of the Botanisches Centralblatt. 



Twigs terete, glabrous. (1). A. colchica. 



Twigs 5-lined, somewhat hairy. (2). A. phyllanthoides.
