 the tail of the lower anther is well developed, so that 

 the group Ansellia cannot be united with Dianthera 

 unless, with Lindaii, the unmanay^eably lonp series of 

 species of Juslicia be increased by sinking Dianthera 

 altogether in it. Lindau assigns these species of sect. 

 Ansellia as " typical " examples of his section 

 Rostellaria (characterised by Lindau as having 

 flowers in dense spikes). The sect. Ansellia, as 

 intimated by T, Anderson, is possibly best dealt with 

 by making it a separate genus. 

 Spikes usually with more than 2 flowers.

 arrangement of Lindau are but one.)

1. J. Betonica, Linn. S}). Plant. 21. Shrubby, nearly glabrous. 

 Leaves :> by 1^ in., ovate, acuminate, shortly acuminate at the base; 

 petiole J,-J in. long. Spikes 4J by | in. long, strobilate; bracts some- 

 what 4-ranked, ^ by ^ in., ovate, acute, white green-nerved ; bracteoles 

 J by \ in., similar to the bracts. Sepals \ in. long, linear, pubescent. 

 Corolla h in. long, white, rose-spotted. Filaments glabrous, dilated at 

 the top ; one anther-cell below the other, very long-tailed ; pollen 

 ellipsoid with 2 stopples, the longitudinal band passing completely round 

 the grain, with one row of patches on each side of each stopple. Pistil 

 nearly glabrous. Capsule ^ by i in., retrorsely hairy, 4-seeded ; stalk 

 ■^ in. long, solid, stout ; seeds rugose. — T. Anders, in Journ. Linn. Soc.

No example that matches at all closely the ovate-leaved J. Betonica, Linn, (type, 

 Rheede, Hort. Malab. ii. t. 21), has been seen by me from Africa except Carvalho's; 

 and the above distribution is given on the authority of Lindau, who possibly 

 (as T. Anderson) considered several of the succeeding species as mere varieties of 

 J. Betonica. But Lindau admits liicoteba nilyherrensis and N. versicolor as 

 species. 



This species also occurs in India and Malaya.

 rather densely hairy ; otherwise as J. Betonica.
