| Question | Answer |
| Connifer Characteristics | -Important in cold regions -Cones (Strobilis and ovulate) -Needle/Scale-like Leaves -NO flowers or Fruits |
| Cupressaceae (Cypress and Cedars) | -Trees and Shrubs -Mon/Dioecious -Small, scale-like leaves often pressed to branchlets Flattened/fleshy ovulate cones (Juniperus, Taxodium) |
| Juniperus (Cedars) | -Trees/Shrubs -Thin, scaly bark separates in long, loose strips -Evergreen, needle shaped, pointy leaves either spread from branchlet or closely pressed and overlapping -fleshy/leathery cones |
| Juniper berries isn't correct. | Berries are fruits produced by angiosperms, and not fleshy cones as in junipers. |
| Taxodium (Cypress) | -Trees w/ Buttressed trunk -Reddish brown, furrowed, scaly bark -Deciduous, soft, alternate, flattened, spreading leaves -hanging pollen cones -Female cones globose w/ leathery scales |
| Pinaceae (Pines) | -Needle/scale-like leaves. Evergreen -Winter buds covered in scales -Woody cones, usu. long (Abies, Picea, Pinus, Tsuga) |
| Abies (True Firs) | -Trees, Cone to cylinder-like growth form -young bark smooth w/resinous pockets, becomes thick and rough w/age -Leaves flattened w/o stalks, evergreen. -Male cones hanging, Fem cones erect -Boreal to cold temp. regions |
| Picea (Spruces) | -Tree w/tall, tapering trunk & slender branches -Thin, scaly bark -Evergreen, flat, or angled, needles on a Sterigma -Monoecious -Pollen cones cylindric, Ovulate cones w/ many scales |
| Pinus (Pines) | -Trees w/spreading branches -Evergreen, 2-5 needles per fasicle -Pollen cones oblong to cyllindric, Ovulate cones w/ overlapping, spined scales |
| Tsuga (Hemlocks) | -Irregular trees w/central leader -Branches spreading & drooping -Deeply furrowed bark, Red-brown to Cinnamon -2 ranked, small, linear, flat, flexible evergreen leaves -Green, leathery ovulate cones, or small yellowish pollen cones |
| What are the meanings of Monoecious and Dioecious? | Monoecious = 1 house. Male and Female cones on the same plant. Dioecious= 2 houses. Male and female cones occur on separate plants. |
| Difference between Non-native and Invasive | Invasives are non-natives that reproduce and escape their original introductions, often to the detriment of native spp. |
| What is 2-ranked? | Leaves are arranged directly above one another in one plane. |
| Woody Opposite Families (MADCapH) | Adoxaceae (Elderberries) Caprifoliaceae (Honeysuckles) Cornaceae (Dogwoods) Oleaceae (Olives) Rubiaceae (Coffee/Madder) Sapindaceae (Soapberries/Maples) |
| Adoxaceae (Elderberries, Viburnum) | -Large shrub -Leaves Simple or Compound, Toothed -Flowers small, whitish, in flat-topped inflorescences -Fruits fleshy, colorful, 1+ seeded, small, abundant (Sambucus, Viburnum) |
| Sambucus (Elderberries) | -Large Shrub -Opposite, Compound leaves -Large pith in stem -Large, flat-topped inflorescence of small flowers/infructescence of small colorful fruits |
| Viburnum | -Medium-large shrub -Opposite, Simple leaves w/ Prominent Veins -Axillary/Terminal buds long/tapered (claw shaped) -Large, flat-topped, slightly rounded inflorescence/small colorful fruit |
| Viburnum dentatum, or Arrowwood Viburnum is important to what? | Pollenators, saddleback caterpillars, and brachonid wasps. |
| Caprifoliaceae (honeysuckles) | -Shrubs/woody vines, rarely herbs/trees -Evergreen or deciduous -Simple, Opposite leaves, sometimes united at base -Flowers funnel/bell shaped (bilateral) (Lonicera) |
| Lonicera (Honeysuckles) | -Med/Large shrub or woody twining vine -Simple, Opposite, Entire leaves -Cyme inflorescence, bilateral, fragrant flowers |
| Cornaceae (Dogwood) | -Trees/Shrubs -Opposite or Alt, Simple, Entire, Arcuate Veins -Inflorescence sometimes w/showy bract -Drupes (Cornus) |
| Cornus (Dogwood) | -Trees/Shrubs -Simple, Opposite, Entire, Arcuate veins -4merous white flowers, sometimes clustered -Fruits red, white, or blue |
| Oleaceae (Olives) | -Mostly trees/shrubs -Opposite, simple, pinnate compound or palmate w/3 leaflets, entire -Petals absent on native spp (wind pollenated) -Various fruit types (Fraxinus) |
| Fraxinus (Ash) | -Trees -Opposite, Pinnately compound w/5-11 leaflets, or palmate w/3 -Non-showy flowers, absent petals -Samara fruit |
| Rubiaceae (Coffee/Madder) | -All habits -Opposite or Whorled, often hairy -Flowers 4-5merous -Fruit varies (Cephalanthus) |
| Cephalanthus (Buttonbush) | -Shrubs/small trees -Opposite/whorled, deciduous/evergreen, Simple, Entire leaves -Small, funnel shaped in dense flower heads, 4merous -Fruit in two, 1-seeded nutlets |
| Sapindaceae (soapberry/maples) | -Trees, shrubs, woody vines -Simple or compound Opposite leaves -Small flowers w/ developed nectar disc -Sometimes bisexual -Various fruits (Acer, Aesculus, Sapindus) |
| Acer (Maples) | -Trees, rarely shrubs -Opposite, simple (rarely compound), lobed, sometimes toothed leaves -Flowers small, petals absent, unisex or bisexual -Winged schizocarp fruit |
