HALLIERACANTHA Stapf. 



Hallieracantha pulgarensis Elm. n. sp. 



A suberect biennial herb; stem 8 mm. thick, dark green, 

 terete, nodulose, redining and taking roots at the basal joints, 1 

 m. long or longer, branched only toward the top; branches sub- 

 erect and zigzag, fluted or rugosely angled, green and glabrous. 

 Leaves horizonially spreading, flat, membranous, dark green 

 above and much paler beneath, with cystoliths, well scat- 

 tering alternatingly or only opposed by an ovately lanceolate green 

 and sessile bract 1 cm. long, the larger lamina 18 cm. long 

 by 6 cm. wide at the midde, dull greenish when dry^ 

 slightly inequilateral, entire the usually recurved and sub- 

 falcate apex sharply acute to acuminate, base slenderly cu- 

 neate; midvein yellowish brown beneath, rather broad but 

 flattened, shallowly grooved on the upper side; lateral nerves 

 5 to 9 on each side, ascendingly curved, similarly conspic- 

 uous beneath, their terminal portion very coarsely reticulated; 

 petiole 1 cm. long or less, fluted or ridged, glabrous, can- 

 iculate on the upper side. Inflorescence usually solitary from 

 the leaf axils, erect, dark green, the strict 1.5 cm. long 

 peduncle striate and nearly glabrous; flowers several in an 

 umbel-like cluster at the end of the peduncle; pedicel 2 to 

 3 mm. long, puberulent or becoming subglabroas, subtend- 

 ed at the base by a number of bracts; bracts setaceous, 

 broadest at the base, erect, unequal, the outer or larger ones 

 nearly 3 mm. long, hispidulous; calyx pale green, linearly 

 setaceous, the 5 segments united at the very base, finely 

 glandular pubescent, 1 mm. wide at the base; corolla white 

 or creamy white, 1.5 cm. long, 5 mm. wide across the 

 upper inflated one half, glaiirous, the basal one third 

 constricted, 2-lipped; one of them with 3 rugose lobes and 

 conspicuously reticulately veined; the opposite lip much nar- 

 rower and shorter, striately veined, broadly notched at the 

 apex; both of the stamens are fertile; filaments slenderly 

 curved, 5 mm. long, glabrous, attached below the middle of 

 the corolla; anthers broadly ovate, 1.5 mm. long, basifixed, 

 notched at both ends, slightly superposed; ovary brown and
