4. VERNONIA (LEPIDAPLOA) CLARENCEANA, H. f. (ante, vi. 11). 
Hab. Fernando Po, alt. 7500-8500 feet. (Fl. Dec.) 
5. STENGELIA CaLvoana, H. f., n. sp. Ramulis velutino-pubescen- 
tibus, foliis caulinis lanceolatis sessilibus deorsum longe attenuatis 
basi auriculato-bilobis membranaceis acute dentatis, corymbis laxe 
8-10-floris, capitulis late hemisphzrico-campanulatis, involucri foliolis 
extimis linearibus herbaceis intermediis in laminam maximam oblon- 
gam dilatatis intimis coriaceis obtusis, pappi setis multiseriatis com- 
pressis pilosis, acheniis teretibus glaberrimis, receptaculo amplo 
plano lzevi. 
Hab. Cameroons Mountains, alt. 2500-7000 feet. (Fl. Dec.) 
Suffrutex 8-12-pedalis. Caulis robustus, ramosus, sulcatus. Folia in- 
feriora ignota, caulina 6-10 unc. longa, membranacea, superne glaber- 
rima, subtus ad nervos pubescentia. Capitula longe pedunculata, 
2 unc. diametr. Involucri squame crasse coriacez v. herbacez, basi 
confluentes, extimze subsquarrose ; intermediz lamina oblonga 3 unc. 
longa, colorata ; intimze oc-seriatze, lineari-oblong, concave, coriaceæ. 
Pappus subrufescens, niteus. Corolle cyanew; tubus gracilis, ore 
ampliato. Stamina exserta, antheris breviter caudatis. 
A very fine species, allied to the following and to S. Adoensis, 
Schimp., but differing from both in the sessile cauline leaves with 
auriculate bases. 
6. SrENGELIA INSIGNIS, H. f., n.sp. Ramulis robustis pubescen- 
tibus et glanduloso-pilosis, foliis graciliter petiolatis lanceolatis acu- 
minatis basi anguste inzqualiter bilobis argute dentatis glaberrimis, 
corymbis laxe 10-12-floris, capitulis late hemisphaerico-campanulatis, 
caeterum fere S. Calvoane. 
Hab. Cameroons Mountains, alt. 3000-7000 feet. (Fl. Dec.) 
A totally distinct species from S. Calvoana, differing in the 
glandular hairs of the stem and corymb, and the slender petioles 
of the much smaller leaves, which are attenuate at the base and 
there unequally bilobed. The capitula strongly resemble those of 
S. Calvoana ; but the laminæ of the intermediate scales are smaller, 
shorter, and broader, and the innermost scales are less numerous, 
and have short, rather membranous appendages. 
7. ADENOSTEMMA VISCOSUM, Forst. (ante, vi. 12). 
Hab. Fernando Po, alt. 4000-8000 feet. Cameroons Mountains, alt. 
/900feet. (Fl. Dec.-Feb.) 
8. MIKANIA CHENOPODIIFOLIA, Willd. 
Hab. Cameroons Mountains, alt. 4000-7000 feet. (FI. Dec.- Feb.) 
A common tropical littoral plant on both coasts of Africa and 
in the Indian Archipelago.
