Poison Ivy

I never got a good shot of the poison ivy when it was in bloom. But now it’s really drawing attention to itself with color. Many songbirds eat the seeds and fruit. Bears, rabbits and deer eat the foliage with apparent immunity–in fact only hamsters and primates are known to have allergic reactions to it! Of course, it is identifiable by its three leaves, regardless of other variables– it can be a shrub, a trailing or a climbing vine. The poison is urushiol, a compound found in the sap. Urushiol oil can still be active for years after the plant is dead, so an old vine is still poisonous. Also, mangoes are in the same family, and people who are sensitive to poison ivy can have a similar reaction to mangoes. Jewelweed is a natural remedy for poison ivy. Native. Virtually unknown in Europe. Anacardiaceae family.

Poison Ivy (Toxicodendron radicans)

Thin-leaved Sunflower

Near the aqueduct bridge. I include the leaf picture to show how much the leaf helps in identification. You can see the leaves are directly opposite each other (instead of alternate). Also they have toothed edges. The really distinctive thing about them is that in addition to that central dividing line (the midrib), they have two prominent veins running somewhat parallel to the midrib. That seems to be a consistent characteristic among sunflowers. This variety is only 2-5 feet tall. Native. Aster family.

Seaside Goldenrod

Flowers from August through November. Bigger flowerheads than most goldenrods. Aster family. Native.

Seaside Goldenrod (Solidago sempervirens)

Thin-leaved Coneflower

Related to Black-eyed Susan (both a kind of coneflower), but generally with smaller flower heads. Composite family. Native.

Thin-leaved Coneflower (Rudbeckia triloba)

Wreath Goldenrod

A.F. Irit thought this would make a good wreath, and that turns out to be the name of this goldenrod, one of the few varieties that has the flowers in clusters near the stem like this, and not in terminal clusters. You can see that the stem is blue-gray, inspiring the other name. Native.

Bonus pictures: this plant is near a high aqueduct bridge which overlooks a tributary to the Charles River. The bridge is covered with graffiti…

 

Chicken Mushroom

I think we have already included this kind of fungus (Sulphur Shelf), but this is a nice example. Now Irit and I always test-feel them! Cold! Clammy! Edible but no thanks!

Chicken Mushroom (Laetiporus sulphureus)

Common Beggarticks

Another tall plant in the Centennial meadows. Like the other plants with tick in their name, this has barbed seeds that attach to passing creatures for distribution. Aster family.

Common Beggarticks (Bidens frondosa)

Fernleaf False Foxglove

Even as most of the wildflowers are looking toasted or wilted, I’m still coming across new and unfamiliar flowers. These blossoms are not so pretty, but the buds are very distinctive and beautiful. False foxgloves are partially parasitic on oak trees, and therefore always grow near oaks. Figwort family. Native.

Fernleaf False Foxglove (Aureolaria pedicularia)

Yellow Coral Fungus

With new wildflowers scarce, I do find other things catch my eye, like these small yellow fingers of fungus. I hope this is the correct identification.

Yellow Coral Fungus (Clavaria amoena)

Sulphur Shelf

The procession of new flowers has slowed, but a little rain has brought out lots of fungus. Today we noticed this ruffly specimen. It’s edible, and not the same as another edible mushroom I posted, Hen-of-the-woods. Can be prepared like chicken, but only eat young fresh ones! And start with just a little! Psh.
