ROSACEAE. 



CHAMAEBATIA. 

 (Family Rosaceae). 



Small hairy shrubs: evergreen. 

 Twigs terete with quickly ex- 

 foliating bark, rather slender: 

 pith small, rounded, brownish, 

 continuous. Buds small, oblong, 

 acute, 2-edged, with 2 or 4 scales. 

 Leaf-scars alternate, nearly en- 

 circling the twig, triangular, ob- 

 literated by the deciduous cortex 

 but evident on the denuded twig 

 as 3 subconfluent circles, each a 

 bundle-trace: stipule-scars lack- 

 ing. Leaves subsessile, elliptical- 

 ovate, thrice pinnate, with minute 

 overlapping rather acute leaflets. 

 Chamaebatia, like Chamaeba- 

 tiaria, is a delicate evergreen with 

 fern-like leaves cut into minute 

 leaflets. It is easily distinguished 

 from the latter genus in its more 

 decompound foliage with the very 



small leaflets glandular-mucronate. Neither genus is ap- 

 proached in delicacy of foliage by any other flowering plant 

 likely to be seen by the ordinary observer. 

 Twigs glandular-bristly, very smooth when denuded. 



C. foliolosa.
