12. R. bignonizefflora, S. Moore in Journ. Bot. 1880, 198, partly. 
Hairy, innovations pubescent somewhat viscous. Leaves 2 in. long, 
ovate, subobtuse. Flowers axillary, solitary; pedicels 1 in. long; brac- 
teoles # in. long, ovate, trunvate-based, sometimes petioled. Calyx ? in. 
long and more, divided nearly to the base ; segments 5, subequal, linear- 
ligulate, obtuse, 2 anterior united } in. up, 3 others nearly free. Corolla- 
tube 4 in. long, linear-cylindric portion of tube 24 in. long. Pollen 
globose, honeycombed. Capsule more than # in. long, contracted at the 
base, glabrous, perfecting 6 seeds.—Dischistocalyx bignoniiflorus, Lindau

This is hardly distinguishable from RB. megachlamys. The description (except 
as to the flowers being sometimes sessile) is taken from S. Moore’s type specimen. 
Lindau, l.c. 306, attributes to Dischistocalyx echinate pollen, but Welwitsch 5202 has 
the honeycombed pollen typical of Ruela; the wrong plant must have been ‘sent 
Lindau. 
13. R. Currori, 7. Anders. in Journ. Linn. Soc. vii. 24. Branch 
stout, divided, densely tomentose with very short grey-white hairs. 
Leaves petioled, ovate, entire, shortly softly hairy. Pedicels 3 in. long. 
Calyx } in. long, divided to the base into 5 subequal linear-ligulate 
segments, with many short soft hairs. Corolla 2 in. long (blue, fide 
T. Anderson); linear-cylindric portion of the tube 3 in. long, upper 
inflated portion very large. Stamens, anthers and pollen of the genus.

The material is so scanty, and in such poor condition, that I can add little to 
Anderson’s description except that the stamens and pollen are as of Ruellia. The 
leaves present are only # in. long, but they are on small lateral shoots ; the plant pro- 
bably bears very much larger leaves. The pedicels were probably 2-bracteoled at top, 5 
throughout this group. Corolla as of R. patula, but much larger. racteoled at top 
14. R. diversifolia, S. Moore in Journ. Bot. 1880, 198. Branches 
shrubby, with many soft spreading long white hairs. Leaves 14 by 1 in., 
ovate, subentire, base truncate, tip hardly acute, both faces softly hairy-
