my specimens a two-ovuled ovary; no doubt about it. So Hegel- — 
maier’s objection to its identity with S. polyrrhiza falls to the — 
ground. I had the other day a long letter from him, written be- _ 
fore he had received your second envoy. He was then thea busy — 
as military surgeon, (He was a medical man before devoting him- — 
self to botany.)” Mr. Austin,in a note dated Sept. 9th, writes: 
“The utricle contains but one ovule in all the fronds I have exam- ~ 
ined, but I think there is evidently an empty space on the other — 
side of the utricle, fully as Jarge as the space occupied by the single — 
ovule.” This isa good example of botanical sagacity. We still a 
think, however, that there is some peculiarity about the plant. The — 
tenuity of the nerves has been referred to. In the full grown plant, — 
now floating before us, there is a strong ridge down the middle of — 
the frond, giving it a different appearance from the common form. — 
However this may be, we believe the engraving from Mr. Austins 
drawing, which, through the kindness of a friend, we are enabled to — 
present, is the first accurate delineation of the parts of fructification _ 
of this plant which has yet been made. ve 
Explanation of the Plate-—Fig. 1. Frond, showing the nerves at @ — 
aaaaaa; young frond at b; fruit at ¢; with the seed d; rootlets 
at e.—Fig. 2. Cross-section of frond showing it to be biconvex, also 
showing the air-cavities—Fig. 3. Fruit.—Fig. 4. Seed, showing © 
the raphe at r, and the hilum at h; x is the apex of the seed, which — 
opens under pressure, when also the albuminous portion issues out — 
through this opening.—Fig. 5. Cross-section of seed, showing its 
three distinct parts, viz: a, album ; s, starch ; and#, testa, or outer — 
coat.—Fig. 6. Shows the albumen which has been pressed out of | 
the seed, and the germen, g, protruding from the apex.—Fig 7 18 — 
the same with the germen separated. ; 
78. Nuphar Inteam, Smith, Var. pumilum.—Common in the Hacken- — 
sack River, etc., near Closter. : 
Arabis levegata, DC.—Common on the Palisades. ee 
Draba verna, L.—I have never seen about Closter, nor on the Pali- 
sades north of Guttenberg. 
Viola rotundifolia, Mchx.—Not rare on the borders of swamps near 
_ Closter. The upright simple scapes produce the perfect flowers 
which are always abortive; while the prostrate branching stems 
roduce fruit in abundance, and are always covered with 
eaves. ao, et ee 
79, Lythrum lineare, L.—is this year quite abundant near Little 
Snake Hill: in prime, Sept. 12th. oc 
Artemisia biennis, Willd—Seems well established at Stapleton land. 
ing, Staten Island. It is a western species, that has lately 
begun to travel eastward as a weed. . 
Centaurea Melitensis, L.—I found in a kind of park, on Staten Island: 
it was obviously only a stray or waif. It has established itself 
in California, but I never heard of it before on this side of the 
continent. J. W. Conepon.
