HuiLLA.^ — An annual herb, 3 to 11, usually 3 to 6 in. high ; rhizome 

 parasitical, after the manner of Striga, adhering to the roots of 

 neighbouring plants by means of its short whitish fleshy very brittle 

 fasciculate fibres, chiefly afEecting bulbous or tuberous CyperaceEe ; 

 stem erect, acutely tetragonal, bright green, filled with a very loose 

 pith, rather sparingly branched towards the apex; leaves lanceolate- 

 elliptical, semi-amplexicaul, herbaceous-green, obtusely keeled ; flowers 

 horizontally nodding, almost like Mimulus ; calyx 5-cleft, the lobes 

 binged-keeled ; corolla hypogynous, somewhat salver-shaped, very 

 Wright sulphur in colour, sub-bilabiate, marcescent ; the tube but little 

 exceeding the calyx ; the lobes of the limb 5, ovate, very patent ; 

 stamens 5, inserted on the lower part of the corolla-tube, included, 

 equal ; filaments flattened at the insertion of the anthers, incurved- 

 thickened, longer than the anther-cells ; anthers oblong-linear, 2-celled, 

 •dehiscing longitudinally, with one gland at the apex and two glands 

 at the base, at first exceeding the stigma, at length adhering to the 

 enlarged stigma, forming a ring round the neck of the stigma and quasi- 

 «pigynous by the rupture of the filaments ; the apical gland stalked, 

 eUipsoidal-spathulate, central ; the basal glands smaller, suborbicular, 

 shortly stalked, lateral ; ovary obovoid-elliptical, 2-c6lled, the edges of 

 the valves introflected, the cells many-ovuled ; style central, falling 

 short of the anther-tips or longer, firm, shorter than the thickly club- 

 shaped, rather compressed pubescent stigma which is broadly winged 

 on. both sides ; capsule ovoid, turgid, 2-celled ; placenta at length 

 4-parted, tolerably large, spongy, at length free from the capsule ; 

 seeds very numerous, minute, cinnamon-brown or tawny, subglobose, 

 angular, minutely scrobiculate or foveolate. Parasitical in spongy 

 and marshy densely herbaceous places on clumps of Cyperacese, in 

 company with species of Drosera, Lobelia, Striga, Scleria, Xyris, 

 Eriocaulon, etc., near Lopollo ; in the Monino meadows by the stream ; 

 fl. and fr. Dec. 1859 and Jan. 1860. No. 1516. In elevated spongy
