Corolla somewhat curved, hardly 2-lipped ; tube much inflated in 
the upper half ; lobes 5, ovate, not very unequal. Stamens 2 fertile, 
2 represented by linear filaments without rudiments of an anther : 
anthers at equal height, muticous ; pollen subglobose, with 3 pores, 
the bands not reaching the pole; seeds hardly rugose; otherwise as 
Asystasia. 
Species, beside the one here described, 3 Indian. 
This genus differs from Asystasia by having 2 fertile stamens only, from 
Eranthemum by the upper half of the corolla-tube being swollen. Graptophyllum 
differs little, but by the strongly 2-lipped corolla. The other 3 species of the 
genus are Thyrsacanthus indicus, Nees, Eranthemum indicum, Collett & Hemsl. 
(in Journ. Linn. Soc, xxviii. 105, not of C. R. Clarke), and Eranthemum lateri« 
florum, C. B. Clarke. The pollen does not diffur from that of some Asystasias.
