V. Tweedieana, glanduloso-pubescens, suffruticosa; foliis petiolatis e basi
cuneatâ ovato-lanceolatis acuminatis inciso-serratis, spica capitatâ, corollæ
tubo calyce duplò longiore : laciniis cuneatis bilobis, caule erecto.
Verbena Tweedieana. Niven in bot. mag. t. 3541.
Stems erect, suffruticose, from a span to a foot high,
copiously clothed, like the rest of the plant, with soft glandular
pubescence. Leaves opposite, stalked, ovate-lanceolate,
acuminate, soft and membranous, deeply and unequally serrated,
two inches long, the base cuneate and entire. Flowers
in a short capitate spike. Peduncle three or four inches long.
Bractes solitary, ovate-lanceolate, acuminate, entire, about
half as long as the calyx. Calyx tubular, 5-angular, teeth
erect, subulate. Corolla salver-shaped; tube cylindrical,
pale yellow, glandulai’, bearded within, twice longer than the
calyx; limb spreading, 5-partite, of a rich crimson; segments
cuneate, deeply notched, the anterior one rather
larger. Stamens four, inserted in the mouth of the tube,
pale yellow. Ovarium glabrous. Style inclosed, glabrous,
dilated, and compressed laterally at the apex, the sides prolonged
into two unequal teeth between which is seated the
gland-like stigma.
This lovely species of Verbena is nearly related to V. cha-
mcedrifolia, given at TAB. 9. of this work, and is chiefly
distinguished by its taller and upright stems, softer leaves,
shorter capitate spikes, and larger flowers of a rich crimson.
It promises to be quite as hardy as that species, and will
prove an equally brilliant ornament to the flower border.
