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.”
