Terrestrial Phase. Plant upright from a creeping or under- 
ground rootstock about 6 dm. high, rather leafy, foliage petiolate 
ascending: blades ovate elliptic or elliptic lanceolate, 12-20 cm. 
long abruptly acuminate, both faces of the leaf rough with scattered 
short hairs or nearly glabrous, veins and veinlets rough with 
appressed bristly hairiness instead of muricate,scabrous: bracts 
of the spike strigose on the back and ciliate with long hairs on the 
margin: spike 3—7.5 cm. long: peduncle purple with short spread- 
ing glandular hispidulous hairs: ochreae thin sparingly strigulose 
roughened with short sharp hairs. 
Riparian stage of the variety not as yet found in our locality. 
I have found the plants in great abundance in low places where 
but a few inches of water stood in spring which was completely 
dried up in summec and fall. It does not seem to invade deep water 
in our region, and blooms normally in the terrestrial phase. I have 
collected it from a small pool in the middle of a cultivated field 
southeast of the University, also near the ice house east of the 
University, where its terrestrial sterile branches run high up on the 
sand and gravel embankment of the road. It is here found 
together with another amphibious Persicaria which for want of 
proper material collected in flower, I have not been able to determine 
but which may be a terrestrial form of P. mesochora, stranded 
whea the marshy pool was cut off by the road from one of the lakes. 
I have also found the plant during the last season around Hudson 
Lake west of South Bend, Ind., abundantly in flower and fruit.
