9. MiCcROGLOSSA DENSIFLORA, H. f., n. sp. Ramis teretibus, petiolis 
foliisque subtus glanduloso-pubescentibus, foliis 3-4 unc. long. petio- 
latis ovato-lanceolatis serratis longe acuminatis, corymbis densifloris, 
involucri campanulati squamis 3-4-seriatis obtusis marginibus ciliatis, 
floribus radii ligula elongata, pappo albido. 
Hab. Cameroons Mountains, alt. 7000 feet. (Fl. Dec., Jan.) 
Alte scandens. Caulis robustus, sulcatus. Folia membranacea, superne 
scaberula, subtus pubescenti-tomentosa; petiolo glanduloso-piloso, 
subvilloso. Corymbi ampli, densiflori. Involucra campanulata. Flores 
radii ligula tubo fere zequilonga. 
Manifestly a species of Microglossa, though differing from the 
generic character in the much longer ligula of the ray-flowers 
and white pappus. 
10. DicHROCEPHALA LATIFOLIA, DC.

11. DicHRocEPHALA CHRYSANTHEMIFOLIA, DC. 
Hab. Cameroons Mountains, alt. 7000 feet. (Fl. Jan.) 
This and the above are very common tropical weeds. 
12. DicHRocEPHALA OBLONGA, H. f. (ante, vi. 12). 
Hab. Fernando Po, alt. 10,700 feet. (Fl. Dec.) 
Possibly a form of D. chrysanthemifolia; but if so, a very 
peculiar one. 
13. BLUMEA ALATA, DC., var. Natalensis. 
Hab. Cameroons Mountains, alt. 7000-8000 feet. (Fl. Dec.-Feb.) 
A widely distributed and very variable African and Asiatic 
plant. 
14. VERBESINA (PnEsTINARIA) MONTICOLA, H. f., n.sp. Glaber-

amplis elongatis oc-nerviis, acheniis planis lineari-oblongis margine et 
pice setosis, aristis 2 brevibus scabridis. 
Hab. Cameroons Mountains, alt. 5000-7000 feet. (Fl. Nov.-Jan.) 
Herba l-3-pedalis. Caulis nodosus, crassitie penne corvine, rigidulus.

sepe 3-fida. Pedunculi unciales et ultra. Capitula radio incluso 13 
une. lata. Involucrum late hemisphericum, squamis extimis linea- 
ribus foliaceis, interioribus late oblongis obtusis chartaceis nitidis,

longas strictas desinentes. Fl. radii foeminei, l-seriales, ligula auran- 
tiaca, ad 10-nerviis, tubo brevissimo piloso, achenio abortivo, stylo
