F. Baroni, Baker. (Plate XXVII. figs. 1-6.) 
A much-branched erect shrub, glabrous in all its parts, with 
thick woody compressed ascending branchlets with grey bark, 
distinctly thickened at the nodes, and the alternate internodes 
compressed on different sides. Leaves opposite (or fascicled at 
the nodes through the suppression of a branchlet), obovate, 
obtuse, entire, moderately firm in texture, green and glabrous on 
both surfaces, narrowed gradually from the middle to the base, 
not fully developed till after the flowering time, under an inch 
long when the flowers are expanded. Flowers geminate or fas- 
cicled at the nodes and tips of the branchlets; pedicels at most 
i-j in. long, sometimes bractless, sometimes with a minute 
lanceolate bract a short distance from the base. Calyx ¢ in. long, 
cut down nearly to the base into 5 acute lanceolate segments. 
Corolla whitish, with a cylindrical tube j-4j in. long and an 
obscurely bilabiate limb of five subequal obtuse segments nearly 
4 in. long. Longer stamens and style exserted out of the corolla- 
tube, but falling far short of the tip of the limb.—Central Mada- 
gascar, Baron 1737! Allied to Ruellia, from which it differs by 
its short cylindrical corolla-tube, long limb, and two very im- 
perfect stamens.
