SAXIFRAGACEAE. 



SCHIZOPHRAGMA. 



(Family Saxifragaceae). 



Shrubs, climbing by aerial roots: 

 deciduous. Stems terete, rather 

 slender, finally with exfoliating 

 cortex: pith rounded, greenish, 

 spongy. Buds rather small, the 

 terminal somewhat larger, the 

 lateral mostly developing into* 

 short spurs, solitary, with a couple 

 of exposed scales. Leaf-scars op- 

 posite, U-shaped, somewhat raised, 

 nearly meeting: bundle-traces 5: 

 stipule-scars lacking. 



Winter-characters of 8. hydran- 

 geoides are given by Schneider, 

 f. 223; and Shirasawa, 282, pi. 12. 

 This and the following genus 

 are often called climbing hydran- 

 geas, but the climbing habit is 

 found also in Hydrangea. 

 Twigs red-brown, sometimes loose- 

 ly hairy. S. hydrangeoides.
