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.

Frutex ramis tenuibus elongatis laxiter ramulosis ; foliis parvis petiolatis ovatis vel in ramalis interdum oblongis, obtusis, atrate viridibus sparse et breviter pilosis ; inflorescentiis axillaribus laxissime paucifloris ; bracteolis minutis ; calycis segmentis subulatis hispidulis ; coroll^e tubo infundibuliformie, labio postico ovato emarginato, antico sub- rhomboideo lobis apicalibus subaequalibus brevibus rotundatis ; antherse partibus valde sejunctis ; ovario ovato cum disco brevi circumdato ; capsula fusiforme, seminibus 4. 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.
