"The most abundant woody plant is Amorpha canescens, which ia 

 common all over the sand hills. Next comes the Western Sand Cherry 

 (Primus besseyi). On the sand hills around Thedford the third in 

 order is Ceanothus ovatus. Kuhniastera villosa, which should, perhaps, 

 be classed among the undershrubs, is as common as any of the class. 

 All these belong to the true sand hill flora. Nearly all the other 

 woody plants are confined to the Middle Loup and Dismal River Val- 

 leys. A few, as for instance, Salix fluvialilis, Symphoricarpus occidenta- 

 ls, Primus americana, Amorpha fruticosa are also found in some of the 



The other woody plants along the streams are Comas stolonifera, 

 Ribes floridum, Rhus radicans, Rosa fendleri, Rosa arkansana, Ribes 

 aureum, Rhus trilobata, Acer negundo, Fraxinus pennsylvanica, F. 

 penniylvanica lanceolata, Populus deltoides, Celtis occidental, Juni- 

 perus virginiana, Parthenocissus quinquefolia, Vitis vulpina, Celastrus 

 scandens, Rubus occidental, Ribes gracile, Crataegus coccinea, Ulmus 

 americana and Rhus glabra.— Charles E. Bessey.
