Grindelia camporum E. Greene

Gumplant
Asteraceae (Sunflower Family)



 

Gumplant is an erect herbaceous perennial growing to 4' in height. It typically has several simple to openly branched, somewhat glabrous but sticky-resinous stems. The leaves are alternate with a broad clasping base, and are very resinous and almost leathery. The basal ones are narrowly oblong to broadly oblanceolate, usually sharply-toothed, and up to 7" long, while the cauline leaves are ovate to lanceolate, reduced in size, stiff, and entire to serrate.  The flowering heads are radiate and solitary at the ends of rather stout stems.  The involucres are ± hemispheric to globose, strongly resinous, and have long, green, narrow-acuminate phyllaries in 6-7 series with tips that are strongly reflexed to coiled 360°.  The heads are subtended sometimes but not always by phyllary-like bracts. There are usually 25-27 ray flowers with bright yellow ligules, and many yellow disk flowers that are 5-lobed and tubular with narrow corolla throats. There is a pappus of 2-6 narrow chaffy scales.  This gumplant is normally found on clay or sandy roadsides, grassy areas, streambanks and dry washes of chaparral and coastal sage scrub, growing up to 4000' in elevation in the South Coast and the West Transverse and Peninsular Ranges, and blooming from March to October.   These pictures were taken in the La Jolla Valley of Point Mugu State Park in the Santa Monica Mts. Vars. bracteosum and camporum have been lumped together in JM2.
