Daviesia cordata
species of plant

Description
Daviesia cordata is a slender, erect, glabrous shrub that typically grows to a height of 0.5–1.2 m (1 ft 8 in – 3 ft 11 in). Its leaves are reduced to scattered, spreading, egg-shaped phyllodes 35–120 mm (1.4–4.7 in) long and 22–55 mm (0.87–2.17 in) wide, with a heart-shaped, stem-clasping base. The flowers are arranged in groups of ten to fifteen in leaf axils on a peduncle 20–70 mm (0.79–2.76 in) long, each flower on a pedicel 4.0–6.5 mm (0.16–0.26 in) long with two circular bracts 5–15 mm (0.20–0.59 in) wide at the base. The sepals are 6–7 mm (0.24–0.28 in) long and joined at the base, the upper lobes joined for most of their length and the lower three triangular and about 1.5 mm (0.059 in) long. The standard is yellow with orange at the base and tip, circular to elliptic, 10–12 mm (0.39–0.47 in) long and 6–9 mm (0.24–0.35 in) wide. The wings are pinkish-red to purple and 9.5–10.5 mm (0.37–0.41 in) long and the keel pinkish purple and 8–9 mm (0.31–0.35 in) long. Flowering occurs from July to December and the fruit is a flattened, triangular pod 12–16 mm (0.47–0.63 in) long.
Taxonomy
Davieia cordata was first formally described in 1808 by James Edward Smith in The Cyclopaedia based on specimens collected from King George Sound.

Why this record matters
“Daviesia cordata” is worth following because a concise public description often conceals a longer documentary argument. Here, Daviesia, cordata and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 11, 2025. The linked authority identifier is Q5241750. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1808.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
