£30 DIANDRIA MONOGYNIA. Justicia. 



Calyx of five linear-lanceolate, acute segments. Coral 

 ringent ; upper lip vaulted, with a bidentate apex ; under lip 

 broad, and three-cleft. Anthers double ; lower lobe with a 

 long curved, sharp spur. Capsule oblong, four-seeded, very 

 protuberant at the seeds. Seeds nearly spherical, rugose. 

 Obs. In the foliage, spikes, flowers, and capsule, this spe- 

 cies is exceedingly like J. Betonica, which however, is always 

 a tall, erect plant, with coloured bractes, while this is very 

 bushy, spreads on the ground, and strikes root abundantly 

 at the joints ; the bractes also are narrower, and greener.

Herbaceous. Leaves round, or broad-cordate. Spikes ter- 

 minal, four-sided, occasioned by four rows of roundish ciliate 

 bractes. Flowers solitary, in two rows on the fore-part of 

 the spikes. Anthers calcarate. Common amongst bushes on 

 a dry barren soil, over the coast of Coromandel. Flowering 

 time the wet and cold seasons. 



Roots perennial, somewhat granulated. Stems in young 

 plants erect, in old ones uncertain ; branches annual, small, 

 straggling, round, a little downy, jointed, and swelled above 

 the joints, from one to two feet long. Leaves opposite, short- 

 petioled, oval, or round, entire, pretty smooth. Spikes ter- 

 minal, peduncled, long, erect, generally four-sided, occasion- 

 ed by four rows of orbicular, short-petioled, opposite, ciliate 

 bractes ; besides these there are a pair of small pointed ones 

 which press the calyx laterally. Flowers a mixture of pale 

 yellow, and red ; standing in the axills of the two rows of 

 bractes that occupy the fore-part of the spikes ; on the back 

 part they are generally wanting. Calyx single. Corol ; up- 

 per lip emarginate, erect ; under lip broad, three-cleft. An- 

 thers double, the lowermost calcarate. Seeds two in each 

 cell, bristly.
