evidently exotic nature of the wood and the fact that two distinctly 
tropical lichens, a Pyrenula and a Chtodecton, grew on the same sub- 
strate, show that it does not properly belong to the flora of the 
region where it was found.

Arthrocladia villosa, Duby, at Woods Holl., Mass.— A number 
of specimens of the above-named alga was collected by me during 
July and August, 1884. As the Rev. A, B. Hervey has examined a 
specimen, there can be no doubt as to the identification. 
Prof, W. G. Farlow puts Arthrocladia villosa into Addenda, p. 183, 
Marine Algae of New England, upon the authority of specimens found 
by Mr. Frank S. Collins at Falmouth Heights. In Torrey Bul- 
letin, Vol X., No. 9, p. io6, it is stated that Mr. Geo. W. Perry 
found specimens also at Menanhant, near Falmouth, 
My find is hence (so far as I know) the third one, and the 
locality is the most southern one yet reported.

Fertilization in Arenaria serpyllifolia,— Those who are con- 
tinually noting and recording adaptations for cross-fertilization m 
flowers are to my mind engaged in a useful work. Still, I often 
wonder why they miss the opposite illustrations. The common 
weed Arenaria serpyllifolia affords a neat instance of behavior, 
that results in securing self-fertilization. The flower is at its best 
state of expansion about 8 or 9 in the morning in this region. Ex- 
amined with a lens it will be found that the three pistils, in expanding, 
have curved horizontally to the east. In rotating, the stigmatic apex 
of the pistil catches every one its anther, and 'holds and retains it to 
the end. About the hour named, when the flowers are expanded, the 
pollen may be seen oozing from its cells and completely covering the 
stigma. The stamens of the outer tier mature pollen later, if indeed they 
have any at all, for I have never seen any that I thought truly pollen- 
iferous. I have examined many flowers but never found a pistil that 
had not caught its anther and received pollen in the way described.

Notes from Kansas.— In the Forest Trees of North America, 
Rhammis Caroliniana, Walter, is mentioned as found in Eastern Kan- 
' sas. I have not seen it, but R. lanceolata, Ph., is quite common here. 
Sapindus margjnatus, Willd., grows in Southern Kansas, but it is not 
credited to this State in the Forest Trees of North America, ine

and Southwestern Missouri the latter part of June, and collectea
