Polemoniaceae (Phlox family)

"Stem: hairy or glandular. Leaf: alternate, simple, entire to generally pinnate-lobed, linear to ovate [fan-shaped]; basal short-petioled; cauline sessile. Inflorescence: heads or clusters, terminal, or flowers 1--3 in axils. Flower: calyx lobes connected by narrow membrane forming a pitcher-like projection at sinus, enlarging, not rupturing in fruit; corolla salverform to funnel-shaped. Fruit: ovate to elliptic, explosively dehiscent, valves reflexed on dehiscence. Seed: 1(2--3) per chamber, oblong, generally gelatinous when wet, brown. Chromosomes: 2n=16. Species In Genus: 15 species: North America, southern South America. Etymology: (Greek: glue, from wet seed surface) Note: Annual species self-pollinated; perennial herb species generally cross-pollinated. " [Jepson]

Phytochemistry

Twenty plant species were observed for tannin content. C. linearis showed the highest levels at 1.85%. [Khan et al., 2015]

"At the generic level nearly all species accumulate A-7-rutinoside, K- and Q-3-rutinosides, Q-3- galactoside, Q-3-arabinosylgalactoside and Q-3- gentiobioside. C. macrocalyx is the only species lacking the 3-rutinoside pathway and, with C. diversifolia, lacks the Q-3-galactoside and A-7- rutinoside." [Wilken1982]

"Analyses of extracts among populations of the 14 species of Collomia revealed the occurrence of 13 mono-, di- and triglycosides based on the flavonoids, acacetin, kaempferol, patuletinand quercetin. The glycosides included those having arabinose, galactose, glucose and rhamnose as mono-, bio- or triosides at the 3-, 5-, 3,7- or 7-position. Analyses of floral extracts from ten species revealed the occurrence of two anthocyanins, cyanidin and delphinidin 3-(p-coumarylglucosyl)-5-glucoside.... delphinidin-3-(pcoumarylglucoside)-5-glucoside in C. mazama and cyanidin-3-(p-coumarylglucoside)-5-glucoside in C. rawsoniana [7]."
