Near J. palustris T. Anders., but distinguished by its smaller leaves and narrow bracteoles. Justicia (§ Rostellaria) minor T. Anders. Hab. Darar and Smith Eiver, September, 1894.

Hab. Sheik-husin, Sept. 21st, 1894. The short main stem branches immediately above its base, sending out long slender erect branches 4-5 dm. long and only 1*5 mm in diameter below. They are minutely puberulous, and their internodes bear four longitudinal furrows. The largest leaves have slender petioles 8 mm. long, and a blunt ovate blade 22 x 13 mm., which bears a few short appressed hairs on both surfaces, those beneath being longer. The peduncle of the 2-3-5-flowered in- florescences, and the short pedicels, are almost filiform. The calyx is 5-partite almost to the base, the segments are 3-4 mm. long, becoming longer (4-5 mm.) and linear- subulate in the fruit ; they bear besides the short hairs a few capitate glandular hairs. The corolla-tube is 6 mm. long by 3 mm. in diameter at the mouth ; the upper lip is 5 mm. by 5 mm. broad at the base, narrowing to 3 mm. above. The lower lip is 5 by 5 mm., the lobes 1-1 '5 mm. long. The stamens, which are inserted half-way up the corolla-tube, are 6 mm. long, including the anthers, the halves of which are separated by a connective 1-5 mm. long. The anthers are 1 mm. long. The ovary is 1-5 mm. long, the flexuose style 7 mm. The disc encircling the ovary-base is about -25 mm. high. The narrow fruit is 11 mm. long, the seeds are borne in the upper two-thirds. A well-marked species, characterised by its small leaves and very lax few-flowered lateral inflorescences. It recalls somewhat in its foliage I. Oerstedtiana Lindau, but its leaves are much smaller.
