There are two species of baby's breath in British Columbia. These may be separated as follows:
1. Inflorescence glandular-hairy; calyx teeth 3-4 mm long.........G. scorzonerifolia 1. Inflorescence glabrous; calyx teeth 1.5-2.0 mm long...............G. paniculata |
General:
Perennial herb from a stout rhizome; stems erect, several, usually much branched, glandular above, 0.3-1.0 m tall.
Leaves:
Basal leaves lacking; stem leaves opposite, rounded to linear-oblong to lanceolate, 2-8 cm long, 1.0-3.5 cm wide, obscurely 1-3 nerved, unstalked; stipules lacking.
Flowers:
Inflorescence of a few flowers in a large, diffusely branched, leafy-bracted, panicle-like cluster; flowers stalks glandular-hairy; petals 5, white to pale pink, oblanceolate, rounded to somewhat notched, stalklike at the base, slightly exceeding the calyces, about equalling the 10 stamens; sepals 5, glandular-hairy, the white membrane below the notches contrasting strongly with the usually purplish back of the 5 lobes, united, forming a tube 1.5-2 mm long, fused nearly to the tip.
Fruits:
Capsules egg-shaped, 2-3 mm long, 4-valved; seeds 2-5, nearly black, 1.5-2 mm long, prominently cross-wrinkled and pimply in longitudinal, concentric rows.
If more than one illustration is available for a species (e.g., separate illustrations were provided for two subspecies) then links to the separate images will be provided below. Note that individual subspecies or varietal illustrations are not always available.
