Most of the Bay Area members of Rubiaceae are herbaceous, but a couple have woody stems and one is a large shrub. The ones found on Montara Mountain are all herbaceous annuals.
The leaves are whorled or opposite, and the flowers have a tubular 4 lobed corolla and 4 stamens. The fruit is distinctly two-lobed, which dry and separate into 1 seeded nutlets with hooked bristles.
All our Rubiaceae are of the "Bedstraw" type: sprawling, low growing annuals:
Galium Californicum (Bedstraw), Galium porrigens (Climbing Bedstraw) and Galium aparine (Goosegrass)
Flowers: White, tiny, 4 petaled, with alternate bracts; 3 to 5 per cluster.
Blooms: March - July
Leaves: In distinct whorls at regular intervals along stem; bright green, shiny, lightly haired with sharp point on end.
Fruit/Seeds: Spiny small twin seeds.
Location: Along trails and slopes throughout the lower elevations of the mountain.
Status: Native (probably) - Common.

|Further description & Comment: Long, sprawling annual stems that are four-sided, ribbed and spiny. Sit down in a grassy area along a trail and you'll find it: the whole plant seems to sort of stick to you and your clothing, and the seeds cling to your socks. Some books are not clear on whether it is a native or not.|

I'm not sure of the name "Goosegrass", but the plant (and similar relatives) was collected and dried to make a rustic mattress stuffing, hence the other name of "Bedstraw".
Galium sp. seem to be an effective soothing agent for the effects of Stinging Nettle (Urtica dioica). Although I haven't had the chance to try it, I have reliable testimony that it really does work!
Members of the genus have long been used by Native Americans and earlier eurpeans as medicine for skin lesions.
