 apex, broader and rounded at the base, rounded and slightly ridged 

 on the back, conspicuously depressed on the inner faces, 7 to 8 mm 

 long and 4 to 5 mm wide, the narrow hypostyle extending nearly to 

 the base of the nutlet. 



A broad-topped shrub 2 to 4 m high, with stout stems covered with 

 dark gray bark, and slender only slightly zigzag branchlets, light 

 orange-brown and marked by pale lenticels when they first appear, 

 becoming dark chestnut-brown and lustrous at the end of their first 

 season and dull brown the following year, and armed with many 

 slender straight or slightly curved chestnut-brown shining spines 

 3.5 to 5 cm long.

This species differs from the other described species of Anomalae 

 in the broad rounded or subcordate base of the leaves on the vigor- 

 ous shoots. It is named in memory of Peter D. Knieskern (1798- 

 1871), at one time a resident of Oriskany, New York, author of 

 "A Catalogue of the Plants found in Oneida County," " an inde- 

 fatigable collector, a keen observer, unsurpassed by few botanists 

 in his knowledge of the plants of the region in which he resided."
