1A93637B8B825BC1B35947D81D423950.taxon	diagnosis	Diagnosis. Lysimachia barcae is morphologically most similar to L. hillebrandii Hook. f. ex A. Gray from which it differs by its combination of mature stems villous to tomentose (vs. glabrate), petioles 1 – 3 mm long (vs. 4 – 10 mm), leaves cordate to subcordate or rounded at base, veins conspicuously raised on abaxial surface (vs. leaves cuneate to attenuate at base, veins only slightly raised on abaxial surface) and pedicels pendulous, 35 – 70 mm long (vs. erect, 12 – 45 mm).	en	Wood, Kenneth R., Wagner, Warren L., Fawcett, Susan, Heintzman, Scott (2025): Lysimachia barcae (Primulaceae), a new endemic shrub from Wainiha, Kaua‘i, Hawaiian Islands.

Leaves well-spaced, alternate, firm-chartaceous, ovate, rarely lanceolate, blade (35 –) 40 – 70 × (18 –) 20 – 45 mm, leaves abaxially and adaxially sparsely reddish-brown hirsute to pilose, often more densely so on veins, primary and secondary veins prominent on abaxial surface, purple-red, tertiary veins pellucid, margins entire, flat to weakly revolute, apex acuminate to attenuate, occasionally falcate, base cordate to subcordate or rounded, petioles 1 – 3 mm long, reddish-brown tomentose or pilose. Flowers solitary in leaf axils, 6 - to 7 - merous, pedicels slender, pendulous, 35 – 40 mm long, elongating to 60 – 70 mm long in fruit, with pilose hairs light tan to rusty; calyx 6 - to 7 - lobed, lobes persistent, lanceolate to broadly lanceolate, 5 – 6 × 2 – 3 mm, pilose to strigose; corolla campanulate, lobes obovate, 10 – 14 × 5 – 7 mm, purple, tinged yellowish on margins, veins dark purple, outer and inner surface glandular-punctate; filaments connate from base to 1 / 3 or 1 / 2 their length, 5 – 6 mm long, dark purple, anthers 1.2 – 1.4 mm long; stigma capitate, 1 × 1 mm, yellow-green, style 7 – 8 mm long, dark purple, ovary superior, glabrous, subglobose, ca. 2 × 2 mm, dark purple.

1A93637B8B825BC1B35947D81D423950.taxon	etymology	Etymology. Lysimachia is named for Lysimachus (ca. 361 – 281 BC), King of Thrace and is derived from the Greek lysis (release from) and mache (strife) (Wagner et al. 1990). The species epithet honours its discoverer, Nicolai Barca, Field Coordinator for The Nature Conservancy of Hawai‘i, Kaua‘i Program, in recognition of his many years of keen observations, hard work and dedication protecting the native forests of Kaua‘i.	en	Wood, Kenneth R., Wagner, Warren L., Fawcett, Susan, Heintzman, Scott (2025): Lysimachia barcae (Primulaceae), a new endemic shrub from Wainiha, Kaua‘i, Hawaiian Islands.
