Carpochaete bigeliovii Gray
(Bigelow's Bristlehead)


Family: Asteraceae

Status: Native

Synonyms:
None

Carpochaete bigeliovii has slender sometimes almost viney branches with fascicles of leaves in the axils. The flowers are white or rose colored with five long terminal lobes and are individually larger than most flowers in composite flowerheads. The inital impression is not necessarily that of an obvious member of the Asteraceae. The long and conspicuously two parted stigma is strongly exerted. As with all Asteraceae, the stamens are fused. The stamens of Carpochaete bigelovii are completely hidden within the long floral tubes. There are typically 3 or 4 florets per discoid flower head (no ray flowers.) The phyllaries and leaves are gland dotted. The elongate pappus scales are purple, plumose near the tip and hyaline margined.
