Symphyotrichum laeve (L.) Á. Löve & D. Löve. Smooth Blue Aster. CalPhotos. Jepson eFlora. SEINet Taxon.
Perennial herb, to 70 cm., rhizomatous or rooting at nodes; Leaves, alternate, cauline, linear, 120 mm. × 8 mm. wide, reduced and more lanceolate above, glabrous, margin very shallowly toothed and lightly ciliate, entire above; Inflorescence, panicle with 1° and 2° branches; Heads borne singly on 10-15 mm. pedicels, 8 mm. × 10 mm. wide; Phyllaries in 3+ graduated series, 3-10 mm. margins white to tips diamond-shaped green, all tips acute, few hairs; Receptacle epaleate; Flowers of 2 kinds; Ray flowers, fertile, tube green 3.5 mm. + blade blue 9.5 mm. × 1.5 mm, spatulate-oblanceolate; Disk flowers, outer reddish-purple, inner yellow, corolla, 6.5 mm.; Pappus, bristles, 5 mm.; Cypsela, 3 mm × 1.2 mm. wide, glabrous, veins, 4, prominent. Described from Coll. No. 1278, 20 August 2015. Only var. geyeri is recognized in Colorado per Weber & Wittmann (2012) and Ackerfield (2015). However, the green apical zones of these phyllaries are more diamond-shaped than lanceolate suggesting var. laeve, especially if the phyllaries are described as strongly unequal. The possibility that these plants should be assigned to var. laeve or that var. geyeri should be considered a synonym of var. laeve is discussed in FNANM.

Linum perenne L. (Syn: Adenolinum perenne (L.) Rchb. ) Blue Flax. CalPhotos. Jepson eFlora. SEINet Taxon.
Weber & Wittmann (2012) distinguish between L. perenne and L. lewisii with the character of heterostyly in which some plants have styles longer than stamens and others with styles shorter than stamens. They apply homostyly to L. lewisii noting that the styles and stamens are approximately equal. My plants (Coll. No. 1383) consistently have styles longer than stamens. The key in Ackerfield (2015), based on plant structure and overall shape is not helpful because of the range of characters observed with this collection.
