Walt., Rhytiglossa humilis, Nees); but in Ansellia 
the tail of the lower anther is well developed, so that 
the group Ansellia cannot be united with Dianthera 
unless, with Lindau, the unmanageably long series of 
species of Justicia 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. Sp. Plant. 21. Shrubby, nearly glabrous. 
Leaves 3 by 14 in., ovate, acuminate, shortly acuminate at the base; 
petiole $3 in. long. Spikes 43 by ? in. long, strobilate; bracts some 
what 4-ranked, $ by } in., ovate, acute, white green-nerved ; bracteoles 
4 by 4 in., similar to the bracts. Sepals 4 in. long, linear, pubescent. 
Corolla } 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 4 by } 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. (typ 
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 Nicoteba nilgherrensis aud N, versicolor as 
species, 
This species also occurs in India and Malaya,

rather densely hairy; otherwise as J, Betonica.
