106 LEAFLETS. 
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 27. 
P. cocctnEA (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
