Much resembling P. Baconia, but the calyx-lobes are not imbricate 
and are persistent on the fruit.

GoLunGo ALTo.—A shrub, 12 ft. high, with a widely spreading leafy 
head ; trunk 2 in. in diameter at the base; branches erect-spreading ; 
leaves evergreen ; flower-buds greenish ; fruit drupaceous, juicy, either 
sub-globose or didymous, soft and turning black when ripe, 1- to 
2-seeded. In the forests of Sobato Quilombo ; fl.-bud and ripe fr. 
middle of July 1856. No. 3203 and Co... Carp. 647. 
CazENGo.—A shrub, 3 to 5 ft. high, with a coffee-like habit, white 
flowers, and coriaceous evergreen leaves. In shady forests along the 
river Luinha, and also between Cambondo and the Luinha ; Dec. 1854. 
Colonial name “ Primo de Caffé.” The specimens were given to Wel- 
witsch by Senhor Pereira, and are without corollas. No. 3188. 
The condition of the specimens renders these determinations some- 
what doubtful. 
4, P. radicans Hiern, sp. n. 
A small low-growing shrub, about 6 in. high ; the little trunks 
bending down trailing or decumbent and rooting, glabrate ; 
branchlets pubescent with short hoary spreading hairs, erect or 
ascending, leafy towards the extremities ; leaves (perhaps not fully 
developed on the specimens) opposite, elliptical or somewhat 
obovate, obtusely narrowed at the apex and apiculate with a 
cartilaginous tip, unequally narrowed at the base, firmly char- 
taceous, dark-green and puberulous or hispidulous at least along 
the midrib above, rather paler or browner and more hairy beneath, 
1 to 14 in. long by 3 to § in. broad ; lateral veins about 4 on each 
side of the midrib, inconspicuous ; petiole 4, to 3 in. long, hispidu 
lous ; stipules ovate, subulate-acuminate, almost connate at the 
base, hairy at the back, glabrous inside, about % in. long, deciduous ; 
flowers white, fragrant, tetramerous, about 1 in. long when ex- 
panded exclusive of the exserted style, on short hoary-pubescent 
pedicels, few or several together in abbreviated lateral axillary or 
terminal cymes or terminating short lateral branchlets ; bracteoles 
small, stipuliform ; calyx 4 in. long, shortly hairy outside, cam- 
panulate, somewhat compressed, the limb ;; in. long, 4-cleft, the 
lobes ovate or deltoid, hairy on both sides ; corolla scattered with 
pubescent hairs outside, salver-shaped ; tube 3 to 1 in. long, 
hairy inside, slender; throat bearded ; lobes oval-oblong, pointed 
at the apex, about + in. long, comparatively glabrous inside, but 
with some hairs especially near the base, contorted in the bud 
dextrorsely (as seen from above), spreading or reflexed in flower ; 
anthers linear, about } in. long, glabrous, twice as long as the 
filaments, exserted; ovary 2-celled; ovules solitary, on fleshy 
placentas ; style slender, glabrous, entire, exserted nearly } in. 
beyond the expanded corolla. 
Huit1ia.—In thickets near Lopollo ; fl. Dec. 1859, No. 3184. 
Nearly related to P. subcana Hiern or to P. canescens DC., it differs 
from each by its low habit ; in length of flower and breadth of leaf it 
approaches P. incana.
