Tangential Section.—This section (Figs. 5, 6) shows the medul- 
lary rays to be arranged ina single series of from two to occasion- 
ally twenty superimposed cells. The resin tubes, occurring in the 
midst of a medullary ray (Fig. 6, enlarged 300) are quite numer- 
ous. They are of the usual character. 
As far as could be made out, there are no pits or markings on 
the tangential walls of the wood cells. 
I take pleasure in naming this supposed new species of fossil 
pine in honor of Dr. A. C. Peale, whose party I accompanied 
when it was obtained, and who has done so much, in connection 
with the Hayden and later geological surveys, to elucidate the 
geology of our Western States.

Reseda lutea moving Inland—In passing through a meadow ~ 
to-day, a mile or so out of the city upon high ground, my eye 
was attracted by several greenish lemon colored sprays of a mig- 
nonette. By turning to Volume I., Part 1, of the Synoptical Flora, 
the find is seen to agree with Reseda lutea L., which is “ sparingly 
naturalized from Europe” and localized as “ Nantucket, Mass. and 
in ballast ground.” The meadow where the specimens were found 
to-day is neither, and it becomes a new and interesting locality 
for a rare plant collected but twice before in New Jersey, so far aS _ 
can be determined, and then on ballast. It is not in Gray’s Field 
Book or Wood's Florist. Byron D. HALSTED.

The name which I gave to this new and interesting plant, col- , 
lected in 1894, had, unknown to me, been previously applied by 
Curtis to an entirely different member of the genus. It becomes ~ 
necessary, therefore, to rename the Florida form, and the above is — 
suggested, being descriptive of its habitat. It occurs only in the © 
hottest and driest sand, and is confined to and is the only member
