Shawangunks, as in the pine barrens, the most abundant shrub), and 
the substitution of Pinus rigida, Mill., the pine barren pine, on the 
mountains, for the P. Strobus, L., of the surrounding country, con- 
tribute to the list of plants whose natural habitat is low sandy ground 
rather than elevated mountain districts, though the last named may 
hardly be regarded as typical of sandy regions. 
The reason for these somewhat remarkable occurrences is easily 
found in the similarity of the soil on the mountains, in chemical 
composition, to that of the plains bordering the coast, this being with 
some of these plants evidently more potent than climate, for the average 
annual temperature of these mountain districts is seven or more degrees 
lower than that of the sea-coast.* This has its effect, however, in 
modifying the flora,, as seen in the Poteniilla tridentata and Pyrus 
Americana, DC, of High Point, Siellaria borealis, Bigel, and Haben- 
aria viridis, L., var bracteata, Reich., of its slope; Arenaria Grmtlan- 
dica^ L., and /uncus trifidus^ L., of Sam's Point, with other plants of 
northern range. 
Notes on South-western Plants,— The appearance of Dr. Gray's 
long-expected work on Compositae calls for changes in the names 
under which several of my plants were distributed. 
'^662,=^Malacoihrix sonchoides^ T. & G., but the crown is plainly 
about 30-toothed, 
*666 \ ^^^^^^^^^ multilobafuSy T. & G. 
*203=7>7:v/^ angustifoHa, DC., var. latiuscula, Gray. 
'^fi^o=.Senecio Douglasii^ DC. 
'^6^\^=Bigelovia Drummondii, Gray. A form of Bigelovia gniye- 
olens, Gray, collected at Casuino, A. T., differs from the description 
in having the leaves distinctly rigid. 
*78o is not Verbena poly stachy a, but probably an extreme form of 
Vn stricta^ Vent. It requires further comparison. 
The following notes should be published as extending the ranges 
of species beyond those credited to them. 
Lonicera involucrata, Banks, Mt. Humphreys, A. T. 
Galium Rothrockii, Gray, Mogollon Mts., N. M. . 
Stevia Plu?mnerce, Gray, Mogollon Mts., N. M. 
Kuhnia eupatorioides, L., at various places in N. M., and A. T. 
Brickellia floribunda. Gray, Burro Mts., N. M. 
Aphantostephus Arizonicus, Gray, Central N. M. 
Erigeron glabellus, Nutt, Mogollon Mts., N. M. 
Erigeronflagellaris, Gray, Central Arizona. 
Erigeron Rusbyi, Gray, Mogollon Mts. of South-western N. M., 
not of A. T. 
Helianthus Maximiliani, Schrader, Central Arizona. 
Coreopsis Drumrnondii^ T. & G., Central Arizona. 
Schkuhria Hopkirkia, Gray, Western N. M. 
Hymenopapptis Mexicanus^ Gray, Northern Arizona. 
Polypteris Hookeriana^ Gray, Central N. M.
