Posts Tagged ‘River birch Fruit’

This is another of those posts full of all of the things I’ve seen that wouldn’t fit in other posts.

1. Oak Apple Gall

This oak apple gall was about the same diameter as a quarter. Apple galls are caused by a wasp (Amphibolips confluent) called the oak apple gall wasp. In May, the female wasp emerges from underground and injects one or more eggs into the mid-vein of an oak leaf. As it grows the wasp larva causes the leaf to form a round gall. Galls that form on leaves are less harmful to the tree than those that form on twigs.

 2. River Birch Fruit

The female catkins of native river birch (Betula nigra) will form cone shaped fruit called a strobiles. The seeds in the fruit, called nutlets, are dispersed by the wind. River birch is a popular ornamental tree because of its peeling and curling reddish brown bark. It’s my favorite birch tree.

3. Robin

This robin let me walk right up to him and snap a few pictures.

4. Blue Jay

This blue jay didn’t want any part of having his picture taken and thought he was hidden.

5. Frog on a Log

This bull frog sitting on a log was fidgety and his movements told me that one more step would make him launch himself into the water. I didn’t take it, and he stayed dry.

6. Frost Bitten Sensitive Fern

Sensitive fern (Onoclea sensibilis) gets its common name from the way even a light frost damages it. This spring sensitive ferns and many other native plants miscalculated and came up early, and a late frost made their leaves wither and turn brown.

7. Interrupted Fern

Interrupted fern (Osmunda claytoniana) looks frost bitten, but it wasn’t. The brown parts are fertile, spore bearing leaflets that appear in the middle of the leaf, interrupting the green, infertile leaflets.

8. Interrupted Fern

 The fertile leaflets of interrupted fern are completely covered with spore-bearing structures called sporangia. The sporangia have small openings that the dust like spores are released through during the summer. The fertile leaflets will wither away and fall off after the spores are released, and by the time fall arrives each leaf will have a gap between its infertile, green leaflets.

9. Grapes

The flower buds of wild grape look like miniature versions of the fruit that will hang here later on.

10. Big Leaf Aspen Leaves

The white leaves of large toothed aspen (Populus grandidentata) mean the tree hasn’t started photosynthesizing. These trees, along with many oaks, are the last to green up in spring. Some call them white poplar (Populus alba,) but that is an entirely different tree, even though they are both in the poplar family.

11. Poison Ivy

The shiny, purplish bronze, spring leaves of poison ivy (Toxicodendron radicans) make you want to reach out and touch them, but if you do you’ll be sorry. It usually takes about two weeks before the itchy and sometimes painful rash goes away. This plant can grow creeping along the ground, as a shrub, and as a vine like the one pictured. If you spend any time in the woods in this part of the country it’s a good plant to get to know well before you meet face to face. Later, these shiny purple leaves will become green and won’t be quite as shiny, and the plant will blend right in to the background.

12. Royal Fern aka Osmunda regalis

American royal fern (Osmunda spectabilis) is probably the easiest fern to identify because there aren’t any other ferns that I know of that look like it. It can reach 5 feet tall and prefers growing near wateron stream and pond banks. I think that it is one of the most beautiful ferns in the forest. According to the book How to Know the Ferns, written in 1900 by Francis Parsons, the European version of the royal fern (Osmunda regalis) can grow to 10 feet in Great Britain.

13. Striped Wintergreen

Spotted wintergreen is an odd name for a plant with no spots, but that’s what someone decided to call it. It is also called striped wintergreen (Chimaphila maculate,) which makes more sense to me.  This native plant is a close relative of pipsissewa (Chimaphila umbellate,) which is called umbellate wintergreen. The small, white to pink, nodding flowers appear in July. This plant is rarely seen here-I’ve found it in only two places and both are areas that haven’t been disturbed by man in 100 years or more. The U.S.D.A. lists it as endangered in Canada, Illinois, and Maine, and in New York it is listed as vulnerable.
