Mr. Andrews had added many notes throwing full light upon 

 the habitats and the habits of such of these plants as have been 

 found within his own field of observation. These field notes I 

 shall here print, under quotation marks ; having in mind not 

 only their eminent usefulness as helping to understand the 

 forms of Persicaria in the Connecticut valley, but also models 

 of field-note making for any who, in other sections of the 

 country, may interest themselves in the study of the group. 



P. FLUiTANS (Eaton), Greene, Leafl., i. 26. Quite typical 

 specimens, taken from Flander's Pond, Southington, 6 Sept., 

 1904. Mr. Andrews remarks : " The plants were all growing 

 in the water of an artificial pond, the leaves and stems all 

 floating. Even when starting near the shore, or at the water's 

 edge, they invariably took to the water and not to the shore. 

 There were no muddy-shore plants or indications of them." 



This interesting note gives not the least promise of any ful- 

 filment of the prediction which I hazarded in my last paragraph 

 upon this species on page 37. 



P. cocciNEA (MuhL), Greene, Leafl., 35. The straggling 

 riparian state described at the top of page 35 is sent by Mr. 

 Andrews, from about Tyler Pond, Southington, 4 Sept. 1904. 

 "Only one colony, on the border of a small natural pond ; the 

 soil a sandy loam. This colony was growing on ground dry at 

 the time, but well within the limits of the water when the 

 pond is at its height. In other years I have known this colony 

 to extend quite around the pond and to flower profusely." 



More noteworthy, however, is a series from Springfield, Mass., 

 18 Aug., 1904, all the plants sterile, the interest centering in 

 some obviously prostrate branches which, by certain familiar 

 characteristics of the leaf, would at first view seem to make it 

 certain that they had been floating leaves. We had hitherto 

 met with no such prostrate branch with aquatic-looking foliage 

 in this common species. But here is Mr. Andrews' distinct 

 attestation that these were not, as he found them, floating leaves: 

 " Shores of water shop pond; some growing on a grassy border, 

 some on the muddy shore ; but none were seen in the water
