This is hardly distinguishable from H. megacJdamys. The description (except 

 as to the flowers being sometimes sessile) is taken from S. Moore's type specimen. 

 Lindau, I.e. 306, attributes to Dischistocalyx echinate pollen, but Welwitsch 5202 has 

 the honeycombed pollen typical of Bueliia ; the wrong plant must have been sent 

 fiindau. 



13. R. Currori, T. 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 | in. long. 

 Calyx h in. long, divided to the base into 5 subequal linear-ligulate 

 segments, with many short soft hairs. Corolla 2 in. long (blue, fide

 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 aio as of Bueliia. 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, as 

 throughout this group. Corolla as of E. patula, but much larger.
