HuiLtia.—A very elegant herb, annual or biennial, 2 to 5 in. high, 
decussately branched from the base ; root and stems, etc., abounding 
in a very better principle and furnishing by far the best tonic medi- 
cine used by the negroes for dysentery and with still better effects 
in intermittent fevers; radical leaves rosulate, narrowly lanceolate- 
linear, 1 to 23 in, long ; ’ stem-leaves similar or also linear, sessile, semi- 
amplexicaul, Crater erect, deep green, rather fleshy, opposite or the 
uppermost ones at the base of the heads of flowers quaternate and 
resembling a tetraphylleus involucre ; flowers at the apex of the stem 
and branches umbellate-capitate, clear-blue violet-coloured or milk- 
white ; calyx quadrangular, 4-cleft; the lobes erect, broadly mem- 
branous at the base, gradually narrowed and obtuse at the apex, 
obtusely keeled on the back, equalling the corolla-tube, mostly 
obscurely purple; corolla funnel- shaped, hypogynous; the tube 
gradually widened upwards ; the limb-lobes 4, erect-spreading in 
flower, marcescent ; stamens 4, inserted on the corolla-tube between 
the lobes, exserted ; filaments flattened-filiform, equal, each furnished 
below the base with a semi-lunar gland on the corolla-tube ; anthers 
obscurely flesh-coloured or purple, eglandular, longitudinally dehiscing, 
not twisted, introrse ; style straight, filiform, purple, gradually ter- 
minating in the very narrowly truncate and delicately papillose sub- 
bilobed or simple stigma. In damp sandy pastures throughout the 
plateau of Huilla, between Nene and Humpata, from 4200 to 5500 ft. 
alt., very plentiful, in company with Trifolium polystachyum, var. 
psoraleoides (Welw. herb. no. 1902), 7. subrotundum, var. obcordatum
