HviLta.—In moist pastures throughout the district, very plentiful, 
from Oct. to March ; near Lopollo at an elevation of 4500 to 5500 ft. ; 
fl. and fr. Nov. and Dec. 1859 and Feb. 1860. No. 1520. Cf. Cou.. 
Carp. 750. An annual herb, with the habit of a Centaurium and with 
small yellow flowers. Lopollo in damp places ; seeds Feb. 1860. 
Probably this species. Cox. Carp. 749. 
From a note attached to S. affinis, with which species Welwitsch 
had at one time associated this plant, it appears that the latter is a 
powerfully bitter herb and was usually employed with very good 
effect by the colonists in Huilla as a tonic, in lieu of Centauriwm 
umbellatum Gilib. which is not indigenous in Huilla. A decoction 
prepared from this plant, together with Faroa salutaris, is a potent 
restorative after fever ; its virtues were tested by Welwitsch. This 
is probably the plant referred to by Welwitsch, Synopse Explic. p. 55, 
n. 145, under the Portuguese name of “ Fel da terra de flor amarella.”

Hvui1a.—A parasitical, filiform, erect, 2- to 6-flowered herb ; habit 
of Centaurium; stem simple or sparingly branched, quadrangular ; 
leaves ovate-acuminate, connate at the base, rather rigid, distant, 
opposite ; flowers yellow; calyx deeply lobed ; the segments ovate- 
lanceolate ; corolla-lobes lanceolate ; stamens inserted between the 
corolla-lobes, exserted ; filaments in some flowers nearly straight, not 
at all curved below the anthers ; anthers variable in shape, sometimes 
long-spathulate or oblong-claviculate and longer than the style, in 
other cases shortly spathulate, almost shorter than the style and 
hollowed out with one side as it were arched. Parasitical among 
grasses and on clumps of Cyperacee along the banks of the Monino 
river in spongy or swampy places; fl. and fr. Jan. 1860. No. 1521. 
An annual, erect, lovely, little herb, scarcely 8 in. high ; habit almost 
of Curtia tenella Cham. ; stems filiform, mostly shortly bent at the 
base, promptly straightening, simple or with one branch above the 
middle or trichotomous ; branches ascending 1- to 3-flowered ; leaves 
minute, ;, to 4 in. long, sub-connate at the base, ovate-lanceolate, 
keeled, subulate at the apex, squamiform so that the stem seems 
partly leafless, adpressed to the stem ; internodes about 1 (? to 15) 
in. long; cymes 1- to 16-flowered; flowers ebracteolate, yellow, 
mostly pentamerous, 4- to 6-merous ; 5- and 6-merous flowers seen on 
the same specimen ; corolla salver-shaped ; the tube swelled at the 
base, constricted below the limb; the lobes ovate rather obtuse ; 
stamens exserted ; anthers sub-sagittate at the base without glands at 
the apex or with very small glands, but present only on one or two 
of them, at length spirally twisted ; style straight, filiform, exceeding 
the stamens ; stigma globose-cespitate, pileiform, widely hollowed at 
the base and there obtusely bilobed ; capsule 2-celled ; placentation 
free, 4-lobed ; seeds oblong-subquadrate, various in shape, when not
