? C. oblongifolia, Purren's list, Point Barrow to Mackenzie River, 
Herschell Isl. Two different forms have been collected. The 
first one (July 13th, 1906) is in full flower and with very young pods; 
it is erect with sub-adpressed ascending branches, ca. 15 cm. high, and 
approaches much to the typical C. officinalis from which it mainly differs 
in the nerveless pods. The second form (coll. July 17th, 1906) is much 
lower with spreading or arcuate-ascending branches; it was with unripe 
pods and approaches to var. arctica (SCHLECHT.) GELERT (I. c.), but has not 
so narrow pods nor its erect growth.

It is correct to alter RicHARDSoN’s name C. digitata, when the genus 
Dentaria is taken up in Cardamine, as we then have the older name 
C. digitata (LAM.) O. E. SCHULZ.
