ROSACEAE. 



NEVITJSIA. 

 (Family Rosaceae). 



Loosely branched shrubs re- 

 sembling Spiraea and Physocar- 

 pus: deciduous. Twigs slender, 

 long, somewhat zig-zag, decur- 

 rently ridged from the nodes: 

 pith relatively large, rounded, 

 white, continuous: medullary rays 

 rather coarse. Buds rather small, 

 solitary, sessile, ovoid, ascending, 

 with about half-a-dozen some- 

 what keeled or striate scales. Leaf- 

 scars alternate', round-cordate, 

 slightly raised and decurrent: 

 bundle-traces 3, more or less 

 doubled: stipules persistent as 

 small scales from the decurrent 

 ridges above the leaf-scar. 



Neviusia is intermediate in ap- 

 pearance between Spiraea and 

 Physocarpus. It is one of the 

 very local genera and consists of 



a single species which was made known to botanists and in- 

 troduced into cultivation by the reverend Dr. Nevius of Ala- 

 bama, who sent to the Missouri Botanical Garden the plant 

 from which the accompanying sketch was made. 



Winter-characters of 2V". alabamensis are given by Schnei- 

 der, f. 137. 



Twigs golden-brown, puberulent: buds glabrate. 



N. alabamensis.
