by another resemblance, their sudden growth under favorable condi- 
tions. In some places there were clumps of M. uniflora, twenty-five 
stems or more, 15 cm. high, the whole growth of which could not have 
taken more than the two or three days since the rain began; they 
had not grown through the layer of pine needles, but had pushed it 
up; the layer of needles rested on the top of the clump, but so loosely 
that a moderate rain would soon bring it down. After that I saw 
M. uniflora and M. Hypopitys everywhere in the pine woods. 
Among the plants which I mentioned in my first note as not having 
been found in Eastham, but which I collected this season, are Asclepias 
syriaca and Spiraea latifolia, but neither was common. Of the 
Spiraea there were perhaps a dozen individuals, close together, but 
unusually well developed, each one and a half to two meters high. 
They were on land recently reclaimed from the influence of the sea, 
and everything in that station was larger than the normal. Nothing 
in this year’s collecting invalidates the list that I gave of genera that 
one would expect, but that I did not find; Rudbeckia, Arctium, 
Geranium, Thalictrum, Anemone, Aquilegia, Berberis, Desmodium 
and Crataegus; to these I can add Agrimonia, Aralia, Arisaema, Leon- 
todon, Mimulus, Nepeta, Osmorhiza, Sanicula, Saxifraga, Urtica, 
Veronica, and Vicia. While it is likely that representatives of some 
of these genera may yet be found here, it may be fairly assumed that 
the conditions are not favorable to them. Nearly all the species 
that this year’s collecting added to the list belong to the category 
of “specialties” as understood in my first note, species found only in 
limited stations; among them Myriophyllum humile, Sagittaria 
latifolia, Polygonum Muhlenbergii, P. sagittatum, Apocynum andro- 
saemifolium, and Helianthus divaricatus; none of them worthy of 
much note elsewhere, and here only on account of their scarcity and 
isolation. Of marine species, only one is to be noted, Suaeda mari- 
tima; in previous years all my Suaeda was S. linearis, this year all 
S. maritima; probably both species are common, but I had not noticed 
the distinction. Of the “domestic species” I can note Euphorbia 
maculata; I had been on the watch for this species, so common in : 
most places, but it was not until September of this year that I found 
it; there was only a single plant, colored bright red, but without a 
trace of a spot on the leaves. Of Taraxacum erythrospermum I found 
two plants only, and of Anthemis arvensis var. agrestis only one. 
Eragrostis megastachya was common near my house. It is a handsome
