Week 3 (Bear Branch Nature Center)

Page history last edited by djl002 13 years, 10 months ago

Plants:

1)     White Pines

        Pinus strobus

        Pinaceae

        The ancient Greek word strobilos referred to the cone of a fir tree but was itself a reference to some ancient tree used for incense named strobus. The cones of white pine evidently were also burned in ceremony (my reference didn't say by whom). So the sci name refers to the long cones of white pine. White refers to the color of the wood and the bluish-white sheen to the needles.

Branches grow in tiers and needles grow in bunches, 5/bunch. 

Cones Needles  

 

 2)     Spatterdock

        Nuphar lutea

        Nymphaeaceae

        Belongs to water lily family; epithet means "yellow," which refers to the flower.

Hollow Stem

 

3)     Wild Blackberry

        Rubus pensilvanicus

        Rosaceae 

 

4)     Wineberry

        Rubus phoenicolasius

        Rosaceae

        Has distinguishable red hair-like spines.   

 

 5)     Multiflora Rose

        Rosa multiflora

        Rosaceae 

        Has compound leaves, with feathery appendages at bases of leaves.  Note the green stem. 

 

*      American Chestnut

        Castanea dentata

        Fagaceae 

        Some remnants of populations survive, due to their high susceptibility to a Chinese fungal disease. 

Toothed Leaf  

 

 6)     Amur Honeysuckle

        Lonicera maackii

        Caprifoliaceae

        An invasive, aggressive shrub with opposite branching, simple leaves, small, tubular white flowers and red berries.

 

7)     Japanese Honeysuckle

        Lonicera japonica

        Caprifoliaceae   

        An invasive vine with white flowers that turn yellow after pollination.

 

8)     Canadian Onion

        Allium canadense

        Alliaceae

         Forms allicin, which is the primary compound in garlic flavor.

 

9)     Garlic Mustard

        Alliaria petiolata

        Brassicaceae

        A leafy dicot with thick stems and flowers with 4 petals and 6 stamens.  Has fungicidal properties.

When just coming up in spring, looks very vaguely like violets because of the heart-shaped flowers.

 

10)     American Beech

          Fagus grandifolia

          Fagaceae

Terminal Bud Fruit

 

11)     Black Rasberry

          Rubus occidentalis

          Rosaceae

 

12)     Skunk Cabbage

        Symplocarpus foetidus

        Araceae

        This family also contains the philodendron houseplants.  S. foetidus flowers contain a "spathe," which is a modified leaf surrounding a "spadix," which is a fleshy cluster of flowers. This plant is often one of the first to bloom, due to the fact the heat it produces with its fast metabolism can melt snow from around the plant. 

Fruit  

 

 13)     Bloodroot 

        Sanguinaria canadensis

        Papaveraceae

        The plants in the poppy family produce a colorful sap.  The sap of S. canadensis happens to be orange.

 

14)     American Wild Strawberry (two of these- see 25, can we erase?)

        Fragaria virginica (virginiana?)

        Rosaceae

        This plant has compound leaves composed of three hairy, toothed leaflets.  It bears small, tasty berries.   

 

 

 

15)     Mayapple

          Podophyllum peltatum

          Berberidaceae

 

16)     Trout Lily

          Erythronium americana

          Liliaceae

 

17)      Musclewood/Ironwood

          Carpinus caroliniana

          Betulaceae

 

18)     Silky Dogwood

NOTE Change: I got the common name of this plant wrong, the Latin name is right, but the common name is 'silky dogwood' not 'red osier dogwood'.

          Cornus amomum

          Cornaceae

Terminal bud

There are more pictures of some of these plants on the picasa album to which I've linked. Just click on the link that says "view all" to see the rest.

Wendy and I created the log for this week, but we didn't want to put everything up at once. We've listed the specimens for which we had the best pictures, so hopefully other people got good shots of the other things too. If I've made any mistakes here please let me know!

I finished part of my album for this, so I linked the plants to the respective images in my album. More to come.

Regarding Silky Dogwood, I too had it in my notes as Red Osier Dogwood.....I am going to ask Dr. McMillan about this one.

That was my mistake, I had the common names mixed up, but I told you the correct sci name.
