Racemes 10–25, axillary, 100–160 mm, 15–25-flowered, axis glabrous or glandular-hispid; pedicels less than 3 per cm, glabrous or scarcely to densely short-glandular-hairy, rarely completely glabrous; bracts oblong, 3–5 mm, apex obtuse. Pedicels patent, (3–) 5–10 mm, equal to or ± shorter than subtending bract, glabrous or glandular-hairy.

Seeds 26–123, yellowbrown, ellipsoid to subglobular, planoconvex, 0.4–0.7 × 0.3–0.5 mm, 0.2–0.3 mm thick, smooth. 2n = 36.

Discussion

Veronica catenata seems to be a relative of V. anagallis-aquatica that is more cold-adapted, as seen in Europe (R. Götte 2007), and native to the flora area. Although no specimens were seen it may be found in Alaska, Connecticut, and Kentucky.
