1909] Collins,— On the Flora of lower Cape Cod 129 
Fleshy fungi vary in frequency; in damp seasons there is sometimes a 
most abundant growth of Amanita muscaria and one or more species 
of Boletus, all through the pine woods; giants, all of them. 
'l'he three classes, marine, domestic and general, include only а 
minority of the species noted; more were found in special limited 
stations. There is absolutely no drainage in the eastern part of the 
town, and in each pond or swamp, within its own hollow, lives a flora 
independent of the others and with a character of its own. The water 
was very low in the summers of 1907 and 1908, and there was an 
excellent chance to study the floras of these neighboring but isolated 
stations. Meeting-House Pond may be taken as an example; Castalia 
odorata was plenty; at times the water was so low that the dry leaves 
crackled under my foot as I walked near the shore; its duplicate in 
miniature, Nymphoides lacunosum, floated in a band, a short distance 
from the edge. Pontederia cordata, Lobelia Dortmanna and Erioca ulon 
septangulare covered quite a zone, from where the water had been in 
the spring, to some distance below its summer level. Around the blue 
water was a broad belt of white sand, like the cornea about the iris; 
this was variegated by vines of flowering cranberry, and geometrical 
patterns made by a prostrate purple grass. Hydrocotyle umbellata 
grew where there was any shade, Gratiola aurea and Xyris caroliniana 
were plenty near high water line. In July, all around the pond, 
among the grass, was the beautiful Sabatia dodecandra; I did not 
find it at any other station in the town; as this passed away, its place 
was taken by Coreopsis rosea, and in late summer two white Eupato- 
riums, E. hyssopifolium and E. perfoliatum, formed adjacent con- 
centric rings, the former on the inside. No other pond had just this 
combination, and each had some special character of its own. One 
was fairly alive with Myriophyllum tenellum, which was absent from 
the others; another made a specialty of Potamogeton, which was lying 
in great windrows on the shore. 
The limitation of species to single localities makes it rather unsafe 
to say that any species does not occur in Eastham, but I feel sure that 
any species I did not see, if occurring at all, must be rare. As species 
of single stations may be noted, among others, Apios tuberosa, Vitis 
labrusca and Spiraea tomentosa; S. latifolia was not seen at all. Epilo- 
bium coloratum and E. adenoclaulon were found, but no E. angusti- 
folium. Asclepias incarnata var. pulchra was not uncommon, 4. 
amplexicaulis was generally distributed, 4. tuberosa I saw once only;
