fore the leaf has expanded, and this element of time may’ be a 
third reason for the limitation noted. On the other hand, the 
outer portion of the leaf may furnish for similar reasons later in 
the season a better feeding ground for the subsequent forms of the 
rust fuugus. * Byron D. HALsten. 
RUTGERS COLLEGE, March 20, 1894. 
Sherardia arvensis in New Jersey. A plant of Sherardia arven- 
sts was found’ by Mrs. Wm. Z. Flitcraft, of Woodstown, N. J., 
Vice-President of the Naturalists’ Field Club of that place, on 
May 16, 1894, in the Library Hall lot in Woodstown, owned by 
Mr. Flitcraft. The lot around the building has been in grass for 
many years, with the exception of a border around it planted in 
rose bushes. The plant was found in the grass plot just inside 
of this border. The one’ specimen is all that was found, and was 
pulled up by Mrs. Flitcraft by the root, so as to better determine 
its character, as the plant was altogether new to her. Miss Cor- 
nelia Woolman, a member of the Field Club, pronounced it Sher- 
ardia arvensis, which was confirmed by myself, and also by. Prof. 
N.L. Britton. How it came in the lot is unknown. It may have 
come from seed deposited with manure or grass seed sown on 
Some bare patches of the lawn within the past two years. It is 
Possible that there are other roots near the place it was found, 
and the plot will not be mowed again for some time, so that other 
Specimens may, if possible, be secured.

Note on Cassia armata. In the article on “The Genus Cassia 
in North America,” which appeared in the BuLtetin for May,* 
the species C. armata S. Watson is characterized as herbaceous. 
Mr. S. B. Parish, of San Bernardino, Cal., has kindly informed the 
author that it is in reality a shrub about four feet in height, and 
adds the following note in regard, to its distribution: ‘It grows 
in dry, rocky places in the Mojave Desert, but not abundantly. 
Daggett is the most western known station, and it ranges thence 
fast, hits the adjoining borders of Arizona and Nevada. The San 
Diego locality quoted by Mr. Pollard is probably a mistake.” 
The error of calling the plant herbaceous appears in the origi-
