Spreading dogbane, Apocynum androsaemifolium.
This has been bothering me forever - I've been seeing it on the trails around Cuyamaca forever, as it seems to sprout abundantly along the trails burned by the Cedar fire, surrounded by endless stands of Palmer's ceanothus. Except it's not listed in my go-to reference for when I have no idea what family a plant belongs to, the Lightner book San Diego County Native Plants which you can just flip through until you see it.
Tonight I googled something along the lines of "What plant families have opposite leaves?", which led me to "How to identify our 50 major temperate plant families" linked from the research-and-resources page of its author, a Rutgers professor, Lena Struwe (by way of a link from SDSU's Plant Systematics Resources), which listed the Apocynaceae family has having opposite leaves. Bringing up that family on Calflora, there was really only one possibility.
