- Pistil
- The pistil is the female portion of the flower located at the center of the blossom. It consists of the style, stigma, and ovary.
- Stamen
- The stamen is the male portion of the flower, and it is clustered around the pistil. It includes the filament and anther. Most flowers have multiple stamens.
- Petal
- Also known as the corolla, the petals enclose the reproductive organs of a flowering plant. They are often brightly colored to attract pollinators, and lend beauty to the plant.
- Sepal
- Also known as the calyx, the sepal encloses the flower when it is in bud form. When the sepals open, the petals are revealed. They are often (but not always) green and leafy-looking.

Orchid
The Orchid family is the largest family of flowering plants, containing some 25,000 species. Orchids, like the grasses and the palms, which they resemble in some ways—for instance the form of their leaves—are monocotyledons. They have one cotyledon, or embryonic leaf, in contrast to the two of most flowering plants. Orchids have simple leaves with parallel veins. Their shape is highly variable between species.
- Vanilla
- Lady's Slipper
- Orchid
Lily
Plants in this family have linear leaves, mostly with parallel veins, and flower parts in threes.
- Turk's Cap Lily
- Wild Garlic
- Onion
- Trillium
- Fawn Lily
- Tulip
- Hyacinth
Mustard
The family was formerly named Cruciferae ("cross-bearing"), because the four petals of their flowers are reminiscent of crosses.
- Cabbage
- Broccoli
- Cauliflower
- Brussels sprouts
- Mustard
- Horseradish
- Watercress
Pink
The leaves are almost always opposite, rarely whorled. The blades are entire, petiolate and often stipulate. These stipules are not sheathforming. The flowers are regular and mostly have 5-way symmetry, i.e. with 5 petals and 5 sepals, but sometimes with 4 petals. The sepals are free from one another or united. The petals are fringed or deeply cleft at the end.
- Carnation
- Bladder Campion
- Swamp Milkweed
- Common Milkweed
- Butterfly Plant
- Sand Milkweed
- Whorled Milkweed
- Deptford Pink
Buttercup
Plants in the Buttercup family are mostly herbaceous plants, but with some woody climbers (such as Clematis) and subshrubs (e.g. Xanthorhiza). Leaves are very often more or less palmately compound. The flowers have many free stamens arranged in a spiral and usually many free pistils. Flowers are most often grouped in terminal racemes, panicles or cymes.
- Delphinium
- Columbine
- Marsh Marigold
- Thimbleweed
- Clematis
- Hellbore
- Larkspur
- Buttercup
Cactus
Cacti are distinctive and unusual plants, which are adapted to extremely arid and hot environments, showing a wide range of anatomical and physiological features which conserve water. Their stems have expanded into green succulent structures containing the chlorophyll necessary for life and growth, while the leaves have become the spines for which cacti are so well known.
- Saguaro
- Barrel Cactus
- Prickly Pear
- Rabbit Ear
Rose
Members of the Rose family have 5 sepals and 5 petals which are flat and wavy at the margins. Each flower has at least ten stamens. All members of the rose family have a hypanthium, which is a bowl-shaped part of a flower consisting of the bottoms of the sepals, petals, and stamens stuck together.
- Rose
- Apple
- Blackberry
- Strawberry
- Raspberry
- Apple
- Plum
- Peach
- Cherry
- Pear
Bean
All members of this family have five-petaled flowers in which the superior ovary ripens to form a "pod", technically called a legume, whose two sides split apart, releasing the seeds which are attached to one or both seams. A significant characteristic of legumes is that they host bacteria in their roots, within structures called root nodules. These bacteria have the ability to take nitrogen gas out of the air and convert it to a form of nitrogen that is usable to the host plant. This process is called nitrogen fixation.
- Bean
- Lupins
- Clover
- Alfalfa
- Peas
- Peanuts
- Soybeans
- Lentils
- Mimosa
- Kudzu
Parsley
The parsley family has flower clusters being in the form of a compound "umbel". The small flowers are radially symmetrical with 5 small sepals, 5 petals and 5 stamens.
- Cumin
- Parsley
- Carrot (Queen Anne's Lace)
- Dill
- Caraway
- Fennel
- Angelica
Smartweed
The seeds of the plants belonging to the smartweed family have a triangular shape. Leaves of these plants have a peculiar pair of sheathing stipules known as ocreae.
- Buckwheat
- Sorrel
- Rhubarb
- Knotgrass
Bellflower
The Bellflower family consists mostly of herbs, shrubs, and more rarely small trees, which usually have milky non-toxic sap. Leaves of these species are often alternate, more rarely opposite. They are also simple and without stipules. Flowers are bisexual, bell-shape, consisting of a narrow tube-like corolla with small spreading lobes. Flowers are fairly often blue. Fruits are often berries, but can also be capsules.
- Bluebell
- Harebell
- Lobelia
- Balloonflower
Mint
The flowers in the Mint family typically have petals fused into an upper lip and a lower lip. The leaves emerge oppositely, each pair at right angles to the previous one or whorled. The stems are frequently square in cross section, but this is not found in all members of the family, and is sometimes found in other plant families. The flowers are bilaterally symmetrical with 5 united petals, 5 united sepals. They are usually bisexual and have a flower cluster that looks like a whorl of flowers but actually consists of two crowded clusters.
- Basil
- Mint
- Rosemary
- Sage
- Savory
- Marjoram
- Oregano
- Thyme
- Lavender
- Perilla
- Self-heal
Aster (Daisy)
Plants in the Aster family typically have one or both of two kinds of florets. The outer perimeter of a flower head like that of a sunflower is composed of florets possessing a long strap-like petal, termed a ligule; these are the ray florets. The inner portion of the flower head (or disc) is composed of small flowers with tubular corollas; these are the disc florets. The composition of asteraceous inflorescences varies from all ray flowers (like dandelions, genus Taraxacum) to all disc flowers (like pineapple weeds).
- Aster
- Common Daisy
- Oxeye Daisy
- Black-eyed Susan
- Lettuce
- Chicory
- Sunflower
- Safflower
- Jerusalem Artichoke
- Goldenrod
- Chrysanthemum
- Dandelion
- Boneset
- Strawflower
- Ragwort
Snapdragon
The plants are annual or perennial herbs with flowers that are zygomorphic (can be divided by only a single plane into two mirror-image halves, much like a person's face), or rarely actinomorphic (can be divided into symmetrical halves by more than one longitudinal plane passing through the axis, much as a pie can be cut into several equal and identical pieces).
- Butterfly Bush
- Figwort
- Foxglove
- Mullein

- A seed needs warmth and water to grow roots.
- The flower sprouts up and down at the same time, send a shoot upwards, and a root downwards.
- The flowers grow more leaves.
- The blossoms open.
- Bees and other insects pollinate the flowers.
- The flowers form seeds.
- The seeds are dispersed and take root.
- The cycle repeats.

Poison Ivy, Poison Oak, and Poison Sumac all fall into this category. Poison ivy grows all over North America, and is most fond of disturbed areas such as stream banks and roadsides. Poison oak grows primarily in Texas, Oklahoma, and the Southeastern and Western United States. Poison Sumac is found in subtropical and warm temperate regions throughout the world, with the highest diversity in southern Africa.
Another plant to watch out for is the wild parsnip (Pastinaca sativa). This plant has an edible tuber, and indeed was cultivated for this for centuries. But if contact with the plant is made with wet (or sweaty) skin, followed by exposure to sunlight, it can cause a purple rash that can last several weeks. In some cases, the discoloration caused by the rash can be permanent.

It is sometimes difficult to assign a color to a flower. Some varieties of a flower in a given species will have blossoms in one color, while another variety will have them in another. Some flowers are difficult to call blue or violet, as the color lies somewhere in between. Red and violet flowers can also be in between. Use your best judgment to meet this requirement. We present a few possibilities here, so do not feel constrained by this list.

This requirement is a fun activity that your Pathfinders are sure to enjoy. Select the flowers carefully, either from your garden (or one you have permission to "raid"), or from a store that sells flowers (a florist or a grocery store). Smell them to be sure they each have a discernible odor, and then determine their identities (you can use a key to do this). Cultivated flowers will generally have a stronger aroma than wild flowers. Allow each Pathfinder to sniff all the flowers without blindfolds so they can learn the smells. When a Pathfinder is ready, apply the blindfold, and hold the flower near the nose. Allow each flower to be sniffed and have the Pathfinder announce its supposed identity. If the Pathfinder cannot get two out of five in the first, try, allow him (or her) to smell them again without the blindfold and be sure the flower can be identified without the blindfold. Then try again.

- 1. Birds:
- 2. Honeybees:
- 3. Bumblebees:
- 4. Butterflies:
- 5. Moths:
It may be necessary to use a pair of binoculars for this requirement, as birds are highly unlikely to visit any flower a Pathfinder is hovering over. Hummingbirds are the most likely avian visitors you will see visiting a flower for food. Bumblebees can be distinguished from honey bees by their size (bumblebees are two or three times larger).
6e
This can be an excellent activity for a campout. The post-dusk observations are quite suitable as a vespers activity, and the daytime observations work well during the Sabbath morning services.
Compare this requirement with requirement 7 of the Shrubs honor.
