This has been supposed possibly to be Rungia repens, Nees, a common weed in 
India; but the seeds differ, and the numerous axillary spikes give it a different 
aspect. 
57. MACRORUNGIA, C. B. Clarke. 
Sepals 5, united half-way up, or nearly free, coloured, scarious, free 
portions broad-lanceolate. Corolla red; tube scarcely 4 in. long; 
anticous lip 1 in. or more, without in the bud, sub-3-fid or subentire ; 
posticous lip broader, emarginate. Stamens 2; filaments long exserted, 
glabrous ; anther-cells 2, oblong, muticous, one placed a little below the 
other ; pollen ellipsoid, with 2 stopples and several rows of minute 
tubercles, obscurely banded. Capsule ovoid ; placente rising elastically 
from the base of the valves; seeds obscurely cerebrose-marked.— 
Shrubs, nearly glabrous. Leaves entire. Flowers in spikes; bract 
ovate, narrowly hyaline-edged ; bracteoles 0, or narrow.

From the fruit, Macrorungia must stand next Rungia or be sunk in it. The 
corolla is very unlike that of Rungia, as is the comparatively large tubular hyaline 
calyx. The spikes are looser than in Rungia, less strobilate, the bracts not (or most 
obscurely) 4-ranked, some of them (not those in one definite rank) empty. 
The distinction between Anisotes and Macrorungia lies in the elastic rising of the 
placentw in the ripe capsule in Macrorungia. Lindau has placed his Symplectochilus
