European Hackberry - Celtis australis

European hackberry fruitThe European Hackberry (Celtis australis) is a tree species that also goes by the names European Nettle tree and Lote tree and is possibly the tree that the "Lotus-eaters" ate from as referenced by Homer.

The large specimen of the Celtis australis in the picture below is located in the "Concepción" historical botanical garden in Malaga, Spain at the beginning of the "Around the World in 80 trees" trail.
large Celtis australis treeThe fruit of the European hHackberry is a small berry like "drupe" that hangs on the end of a short stem connected to the base of the leaf stem. The size of the fruit is about one half inch in diameter.
Below is another view of the large tree (image above) from a different angle.

The leaf of the Celtis australis is simple in shape with serrate margins and measures about 2-3 inches long. The top side is a darker green than the bottom side which is also "fuzzier" also.

The bark is light gray and with age develops interesting shapes. One of the shapes in the picture below looks a bit like an eye.

I found another large example of the European Hackberry tree on the grounds of the Cathedral of Málaga. From the size of its trunk it looks like it has been growing there for a rather long time.

Western Hemlock - Tsuga heterophylla

The Western Hemlock (Tsuga heterophylla) is the State tree species of Washington State. Being originally from Eastern Washington I have to admit that I was surprised to discover that the Western Hemlock was our state tree. I would have guessed that the Western Red Ceder or the Ponderosa Pine would have been much better choices. As it turns out my feeling was not unjustified. The following quote is from official Washington State government website...

http://www.leg.wa.gov/legislature/statesymbols/
“In 1946, an Oregon newspaper teased Washington for not having a state tree. The Portland Oregonian picked out the western hemlock, Tsuga heterophylla for us, but Washington newspapers decided to choose their own and selected the popular western red cedar. State Representative George Adams of Mason County pleaded with the Legislature to adopt the western hemlock. The hemlock, he said, would become "the backbone of this state's forest industry." Adams' bill passed the Legislature and was signed into law in 1947.”

One of the distinctive features of the Western Hemlock is its "floppy" top and branches. One way to pick out the Hemlocks in the forest is to look for the trees that have the top sort of flopped over to one side as if they were too limp to stand up straight at the top. Also in the image above you can see how the end of the branch is somewhat limp.

The "needle-like" leaves of the Western Hemlock are somewhat flat and do not occur in bunches like a lot of other evergreens. They are about 1/2 - 3/4 of an inch long.

These pictures are not actually from a tree in Washington State but rather from a tree in Stanley Park in Vancouver B.C. that was conveniently labeled with the little plate below.

The Quote "Root of hemlock digg'd i' the dark" comes from "The Tragedy of Macbeth" scene one spoken by the Third Witch. It is a bit strange that this quote is used in connection with the Western Hemlock because the "Hemlock" that is referred to in the quote is not a tree and has no resemblance what so ever to this tree. Rather it is a poisonous perennial herbaceous flowering plant with the species name Conium maculatum. It looks like somebody did not do their homework right.

The cones of the Western Hemlock are quite small (less than an inch long) which makes them a favorite for use in arts and crafts as well as for potpourri.


A similar tree is the Eastern Hemlock (Tsuga canadensis) that is the state tree of Pennsylvania.

50 American State Trees Trivia

Did you know that there are only 39 state tree species that compromise the 50 official state trees? This is due to the fact that some of the official state trees species are shared by more than one state.

The Sugar Maple (Acer saccharum) is the state tree of no less than FOUR states! New York, Vermont, West Virginia, and Wisconsin all have the Sugar Maple as their state tree.

In addition there are three more tree species that are each claimed by three different states.

- Indiana, Kentucky and Tennessee have the Tulip Poplar as their state tree.
- Connecticut, Illinois and Maryland have the White Oak as their state tree.
- Missouri, New Jersey and Virginia have the Flowering Dogwood as their state tree.

Five more trees are shared claimed by two different states

- Colorado and Utah have the Blue Spruce as their state tree.
- North Dakota, Massachusettshave the American Elm as their state tree.
- Florida, South Carolina have the Cabbage Palmetto as their state tree.
- Kansas,Nebraska have the Eastern Cottonwood as their state tree.
- Maine, Michigan have the Eastern White Pine as their state tree.

Mississippi has the Southern Magnolia as its state tree and Louisiana as the State Flower.

Three states have two official state trees.

- California (Giant Sequoia and Coastal Redwood)

- Nevada (Singleleaf Pinyon and Bristlecone Pine)

- New Jersey (Red Oak is the official tree and Flowering Dogwood is the memorial tree)


19 States have Evergreen conifers as their state trees

-10 are Pine trees
-4 are Spruce trees
-2 are Hemlocks
-1 is Redwood
-1 is a Douglas Fir
-1 is a Cypress

6 States have Oak trees

5 States have Maple trees

2 States have Cottonwoods

2 States have palm trees

Only one State has a fruit tree as the state tree (Texas - Pecan)

No state has the Western Red Cedar as its official state tree

There are no true firs (genus Abies) among the state trees (Douglas Fir is not a true fir)

Petrified Tropical Forest in Chemnitz Germany


The petrified logs in this image are located in the Chemnitz Museum of Natural History. Researchers have been studying a number of petrified logs that have been dug up over the years in this town in Germany, some of which have been found whole and in a vertical orientation as if the trees were buried while still standing. Studies on several of the logs have lead researchers to believe that the logs are part of a petrified tropical forest that is encased in the sediment and ash layer of an ancient volcano.

One of the tree species tentatively identified at the site is "Arthropitys ezonata Goeppert", a tropical tree species that is long extinct. In fact, all of the logs found at Chemnitz are of tree species that are now extinct.

I first heard about this story from Gus at Eucalytologics who sent me a link to an article in Spiegel Online.
