 [189()] 80. Shrub; innovations hairy. Leaves up to 3 by \\ in., 

 narrowed at either end, hispid, ultimately glabrate, beautifully reticulate- 

 veined beneath ; petiole up to ^ in. long. Spikes hardly 1 in. long, 

 terminal on lateral branches, subglobose ; bracts nearly \ in. long,

 pubescent. Corolla-tube |-1 in. long, linear-cylindric, not inflated at 

 the top ; lobes 5, subequal, ovate, patent. Stamens 2, not exseited ; 

 anthers of 1 hemi-ellipsoid cell ; filaments glabrous ; pollen globose, 

 with 3 large stopples, and longitudinal smooth depressions reaching the 

 pole. Pistil glabrous ; style with 2 small subequal oblong lobes. 

 Capsule \\ in. long, stalked, narrow-ellipeoid (all seen are 1-seeded 

 with the lower ovule infertile) ; seeds nearly smooth. — Lindau in Engl.

This plant is exceedingly like Eranthemuni hypocrateriforme. Lindau makes the 

 present genus have " Rahmen-pollen," and to thus differ from Eranthemum (which has 

 Spangen-pollen ") and be nearer Grapfophiillum . Buspolia appears to me hardly 

 wortli separating from Eranthemum. 1 see no tangible difference in the pollen.

Calyx 5-partite nearly to the base ; segments equal, narrowly lanceo- 

 late. Corolla with 2 large lips ; posticous emarginate ; anticous 3-lobed. 

 Stamens 2 (with 2 rudiments) ; anthers 1-celled, mucronate at the 

 base ; pollen subglobose, nearly smooth, stopples 3 large. Ovary and 

 style glabrous ; branches of the style 2, very small, equal ; ovules 2 in 

 each cell. Capsule ellipsoid, ^-seeded, long-stalked; seeds without 

 hairs, nearly smooth. — Leaves entire. Flowers purple, in short cymes;
