GERANIUM FAMILY GERANIACEAE
The radially symmetrical flowers are showy and have 5 sepals and 5 petals. The petals fall, leaving an erect, beak-like structure, or "cranes bill", another name for geranium. (The name geranium itself is derived from the Greek geranos, or crane.) The leaves are opposite or alternate and are usually palmately lobed.
GINSENG FAMILY ARALIACEAE
The small, radially symmetrical, greenish or whitish flowers are in rather compact clusters and have 5 petals and 5 stamens, the calyx being absent or inconspicuous. The alternate leaves are usually compound.
A mostly tropical family, but includes the ginsengs, sarsaparilla, spikenard and English Ivy.
GOOSEFOOT FAMILY CHENOPODIACEAE
The small, inconspicuous greenish flowers lack petals and are in spikes or clusters in the leaf axils. The leaves are usually alternate and may be lobed or toothed.
Spinach, beets and swiss chard are in the goosefoot family.
GRAPE FAMILY VITACEAE
Mostly woody, climbing vines with tendrils. The alternate leaves are usually palmately lobed and/or toothed. The very small, radially symmetrical flowers are in a cluster opposite a leaf. Sepals are minute or absent and there are 4 or 5 petals (which fall off before opening in the Vitis genus). Fruit is a berry with several seeds.
GRASS FAMILY GRAMINEAE
The stem of a grass is hollow and jointed, and each leaf forms a sheath around a joint and then extends as the leaf blade. The tiny flowers lack petals and are interspersed with scale-like bracts in spikelets. The spikelets themselves are in heads, tassels or branched clusters. Fruit is a grain.
