Family: Rubiaceae Dichotomous Key

Common Name: MADDER FAMILY
Habit: Annual to tree, vine. Leaf: generally opposite (whorled), entire; stipules generally fused to stem, adjacent pairs occasionally fused, or occasionally leaf-like and appearing like whorled leaves. Inflorescence: cyme, panicle, spike, cluster, or flower 1, generally terminal and +- axillary. Flower: generally bisexual; calyx +- 4(5)-lobed, occasionally 0 (Galium, Crucianella) or 6 (Sherardia); corolla generally radial, 4(5)-lobed; stamens epipetalous, alternate corolla lobes, generally included; ovary generally inferior, chambers generally 2 or 4, style 1(2). Fruit: drupe, berry, or 2 or 4 nutlets [capsule].

Genera In Family: +- 500 genera, 6000 species: worldwide, especially tropics; many cultivated, including Coffea, coffee; Cinchona, quinine; many ornamental. Note: Diodia teres Walter doubtfully in California.

Genus: Galium Dichotomous Key

Common Name: BEDSTRAW
Habit: Annual, perennial herb, occasionally subshrub, glabrous to hairy, generally scabrous; dioecious, bisexual, or flowers unisexual and bisexual. Stem: 4-angled, occasionally ridged lengthwise. Leaf: generally in whorls of >= 4, including leaf-like stipules. Inflorescence: panicles, axillary clusters (cymes), or occasionally 1 in axils. Flower: bisexual, or unisexual with sterile stamens or pistils; calyx 0; corolla generally rotate, occasionally +- bell-shaped, generally +- green, yellow to white, occasionally pink or red, lobes generally 4; ovary 2-lobed, styles 2, bases +- fused. Fruit: 2 nutlets or berry.

Etymology: (Greek: milk, from use of some species for curdling) Note: Ovary and fruit generally +- equally hairy on a pl; staminate plants generally identified by vestigial ovaries, pistillate plants generally by vestigial anthers. Galium saxatile L., Galium schultesii Vest, and Galium verum L. are lawn weeds in California.
