A tree in the courtyard of the residency, Golungo Alto; fl. and fr. 
July 1855. No. 3359. <A tree of 10 to 15 ft., rarely reaching 20 ft. ; 
. trunk straight, bare below, much branched above forming a spreading 
nearly globose head completely covered with white flowers. At the 
borders of primitive forests throughout the district; fl. and fr. be- 
ginning of Aug. 1856. No. 3360. A shrub sometimes erect, in other 
cases quasi-scandent with its branches elongated, bare at the base, 
divaricate, somewhat climbing among other shrubs or tall grasses ; 
flowers whitish but the corymbs appearing pale-yellow on account 
of the yellowish involucral scales. In thickets and beds of tall reeds 
near Quibixe ; fl. and fr. Sept. 1855. No. 3361. In the village (of 
Sange), close to the Tacula (cf. Pterocarpus tinctorius Welw. Herb. 
No. 1867), and Intsia cuanzensis O. Kuntze ; fl. and fr. 30 Oct. 1855. 
No. 3362. A low tree with numerous white flowers and more or less 
ovate leaves not auriculate at the base. Sange, fr. Sept. 1857. Cou. 
Carp. 661. A small sufficiently elegant tree of 15 to 20 ft. high, or 
in the secondary woods only 10 to 12 ft. high; trunk straight, slender ; 
bark very bitter; head ovoid-hemispherical ; leaves membranous, 
caducous ; flowers very abundant, corymbose-paniculate, white. In

CaZENGO.—A shrub 6 to 8 ft. high, shaped like a tree ; flowers pale-

Luinha, about 2000 ft. alt. ; fl. and fr. end of June 1855. No. 3356. 
Pungo ANDONGO.—A shrub-like little tree but with a single trunk, 
frondose at the apex; flowers from whitish to lilac. In hot stony 
thickets about Caghuy and Luxillo, sporadic ; fl. and fr. end of May 
1857. A remarkable form on account of the sete of the pappus being 
very thick, and at the apex clavate- thickened ; in this respect No. 3350 
in Golungo Alto approaches this form. The young leaves are tawny- 
velvety. No. 3353. 
This is the plant mentioned by Welwitsch, Apont. p. 586, n. 34, 
where it is described as remarkably ornamental and well worth culti- 
vating. The Molilus furnish a tonic, bitter bark, and are in frequent 
use in cases of fever and diarrhoea. (See Welwitsch, Apont. p. 548 
under n. 84.) The specimens associated here under this name com- 
prise several different forms which perhaps will subsequently require 
to be arranged under distinct subspecies. Welwitsch in a note remarks
