As is the case with all flowers that have the advantage of 
special adaptations for self-fertilization, every flower matures 
seeds. THoMAS MEEHAN. 
Note on some Introduced Plants in Eastern Massachusetts. 
I have been quite interested in the plants I have found about 
Parker River Mill, a small blanket manufactory started here three 
or four years since. In. the last two years I have visited the 
grounds occasionally, and of rare plants for our vicinity I 
have found the following: Helenium tenutfolium, Echinosper- 
mum Lappula, Monarda punctata, Coreopsis senifolia, C. pal- 
mata, Evrodium cicutarium, Medicago denticulata, M. maculata, 
_ Trifolium Macrei, T. tomentosum, Solanum rostratum, Physalis 
_ Pennsylvanica, Veronica Buxbaumii, Helianthus letifiorus, and 
 Dipsacus Fullonum. Also Tragopogon pratensis, from another 
mill near by. 
Some of these plants have appeared but once, and others 
Now seem to be permanent residents in the grounds, although 
they live under disadvantages, as the debris of all kinds is spread 
upon the small enclosure. 
Sherardia arvensis appears to be well established at New- 
buryport, Mass., it having seeded well and increased since it was 
Noticed four years ago.

Additions to our State (California) Flora.—E. L. Greene. (West

This descriptive list comprises six species. Malva borealis, 
of the Botany of California, proves to be MV. parvifiora, L., while 
M. Nicensis, Allioni, has not heretofore been credited or dis- 
tinguished. In the city of San Francisco itself the author finds 
Paronychia Chilensis, DC. From the collection of Mr. and 
Mrs. Lemmon in the mountains of San Luis Obispo County the 
following new species and varieties are described: Thelypodium 
Lemmoni, Eschscholtzia Lemmoni, and Chenactis tenuifolia, var. 
Orcuttiana.
