Kallyinenia reniformis^ Ag. A single specimen, with cystocarpic 
fruit, washed ashore at Revere Beach, Mass., April 27th, 1884. In 
appearance it much resembles some forms of Rhodyjuenia palmcttay 
Grev., but the color is a somewhat different shade of red; the micro- 
scopic structure is quite distinct. It is figured in Harvey, Phyco- 
logia Britannica, Plate xiii., and has not been previously recorded 
as found outside of northern Europe.

Corema Conradii.— Much may be done towards elucidating the 
probable origin and past history of our native plants, by carefully 
tracing their local and geographical distribution in the way Mr. John 
H. Redfield has done in his interesting paper on Corema Conradii 
in the Torrey Bulletin for September, p. 97. As the details given 
under the head of "Nova Scotia and Newfoundland " are meagre, 
and Mr. Redfield appeals to botanical brethren in the British Pro- 
vinces for further facts, I cannot well resist contributing my mite, 
notwithstanding the supplementary records in the October number, 
some of which relate to this Province. 
In the spring of 1864, soon after my arrival in Nova Scotia, I 
found the Corema blooming abundantly on*a bare ridge of quartzite 
rock, eleven miles to the north of Halifaxcity. Wherever there was 
a crevice or crack in the rock there were tufts of Corema, with stiff 
wiry stems. It was about the only flowering-plant on these barren 
rocks. I soon found that the Corema was not rare in the district, 
and could discern it in heath-like tufts on the bare rocky hills from 
the railway cars, in many places. The auriferous quartzite rocks to 
which I refer stretch along the Atlantic coast district of Nova Scotia 
throughout nearly its whole extent. Wherever they are bare enough 
to resist more leafy plants, Corema is apt to be found. It is usually 
associated with Vaccifiia, Corms Canadensis Gaiiltheria procumbens 
Polypodium vtilgare, and, less frequently, Arctostaphylos Uva-ursi. 
On level ground, where the soil is very poor, consisting of gravel or 
sand, the Corema also occurs, not only in our Atlantic Coast district, 
but in other parts of the Province; in such situations it does not 
grow in distinct tufts, but becomes more gregarious, exclusively occu- 
pying large areas, and is usually much dwarfed in growth, the stems 
being often only a very few inches high. I shall endeavor next sum- 
mer, by aid of my students and correspondents, to trace the distribu- 
tion of Corema throughout this Province with more exactness. 
In Nova Scotia the Corema has been so often mistaken for Scotch 
heather [Caliuna) that I have frequently wished it were less abund- 
ant. Compared with Corema, Empetrum nigrum is, with us, compar- 
atively rare.

Big grape-vines.— In the Bulletin for February, 1882, I gave a 
statement of a grape-vine I had visited and measured at Baisden s 
Bluff near Darien, Ga. There were two errors in the account, which
