spicata, T. and G., a Crategus which further investigation may 
prove to be a new species, A/etris farinosa, L., and Panicum vis- 
ctdum, Ell. : 
On the 28th I had an opportunity of spending an hour or two 
at the “Rocks.” This is a section of serpentine, if my limited 
knowledge of geology is not at fault. Large boulders lie scattered 
around, and on a level with the surface are large flat rocks of the 
same formation, some ofthem many square feet in extent. Nearly 
all of these were covered with lichens, especially a species of 
Cladonia. 
On some of them I found Zalinum teretifolium, Pursh, Cro- 
tonopsts linearis, Mx., and the withered stalks of what seems to 
be an Arenaria. 
In the serpentine belt I found, in addition to the plants above 
mentioned, Yucca filamentosa, L., in fruit, Marshallia lanceolata, 
Pursh, Gratiola pilosa, Mx., Callicarpa Americana, L.,and Poly- 
podium incanum, Pursh, while on its borders were Parthenium 
integrifolium, L., Oxydendrum arboreum (L.), DC., Psoralea melt- 
lotoides, Mx., Lobelia Nuttallit, R. and S., and two forms of Vi- 
burnum nudum, L. 
Another trip on the 4th of July as far as the southern borders 
of this section yielded such things as Jatropa wrens, L., var. stim- 
wlosa, Muell., Rhynchosia erecta, DC., Polypremum procumbens, 
L., the long, trailing form of Tephrosia spicata, T. and G., Rhexia 
Mariana, L., Evriocaulon decangulare, L., and Xyris Caroliniana, 
Walt. 
Little expeditions within a radius of a mile or two of head- 
quarters brought forth some pretty good things. 
In the woods a’short distance below the house I found a num- 
ber of fine plants of Clematis ochroleuca, Ait. In another place 
on the edge of a field is a large patch of Thymus Serpyllum, L., 
which must have escaped from the church-yard about one hundred 
yards east of it. 
Delphinium Ajzacis, L., is rather common, one field especially 
being almost blue with it. This plant I have sent out under the 
name D. Consolida, L., but a more careful study of it has shown 
that the latter name is wrong.
