DR. HOOKER ON THE VEGETATION 
Involucri squame sub 2-scriales, enerves, margine scariosz. Recep- 
taculum planum, foveolatum, nudum. Flores numerosissimi, perplu- 
rimi foeminei; tubus corolle gracilis, pappo et stylo gracili dimidio 
brevior. Pappus albus, nitidus, 1-serialis, pilis filiformibus flexu- 
osis scaberulis. Achenium parvum, pallidum, glaberrimum, valde com- 
pressum, oblique obovoideum, margine subincrassato. Fl. masc. pauci, 
5-dentati. 
This belongs to the section with V. attenuata, DC., and is most nearly 
allied to an Abyssinian one called V. inulefolia, Steud. 
2. Adenostemma viscosum, Forst. 
Hab. In Fernando Po, alt. 4-8000 ped. (fl. Dec.) 
Herba 3-4-pedalis, corollis albis. 
I believe that there is but one species of this genus in the Old World ; it 
is a native of Abyssinia (A. Schimperi, C. H. Schultz), of South Africa, of 
all Tropical Asia and the Pacific Islands. The Fernando Po form is the 
common Indian one. 
3. DicHRocEPHALA OBLONGA, H.f.  Hispidulo-pilosa, caule tereti 
apice ramoso, foliis sessilibus patulis lineari- v. oblongo-lanceolatis acu- 
minatis irregulariter pinnatifido-lobatis marginibus recurvis lobis sub- 
remotis incisis lobulis acutis v. mucronatis, capitulis late oblongis pur- 
pureis, involucri squamis 6-3 herbaceis pubescentibus, receptaculo 
columnari. ` 
Hab. In cacumine Clarence Peak, alt. 10,700 ped. (fl. Dec.) 
Herba erecta, rigidula, 1-2-pedalis. Folia 13"-2" long.; 4-3" lat. 
Capitula $3" long.—D. chrysanthemifolie, DC. (Abyssinica, C. H. 
° Schultz) proxima, differt habitu rigido, caule simplici, foliis angus- 
tioribus rigidis acutius lobatis, et preecipue capitulis oblongis, involucro 
oligophyllo et receptaculo columnari. 
The nearest ally of this is D. chrysanthemifolia, a native of Abyssinia 
and India. 
4. HeELicHRYSUM(XEROCHLAZNA)Mannlil, H. f. Caule robusto villoso 
apice ramoso ; foliis densissimissessilibus, patulis demum reflexis, semi- 
amplexicaulibus oblongo-lanceolatis acutis integerrimis enerviis subtus 
marginibusque tomento appresso niveis, pedunculis basi capitulisque 
magnis albis v. pallide stramineis foliaceo-bracteatis, involucri squamis 
numerosissimis hyalinis splendentibus acuminatis. 
Hab. In cacumine Clarence Peak, alt. 10,000 ped. (f. Dec.) 
Herba robusta, dense foliosa, pedalis et ultra, tomentosa. Caulis strictus 
erectus, teres, simplex, densissime foliatus. Folia 2"—3" long., $^-lata, 
acuta et apiculata, inferiora supra glabrata, inferne dense appresse 
lanata, superiora utrinque laxius lanata v. araneosa. Capitula sub- 
paniculatim corymbosa, bracteis foliaceis fere tecta, expansa 1 +' lata, 
pedunculis arancosis bracteolatis. Involucri squame perplurime, mul- 
tiseriatee, suberectze, floseulis 1" excedentes, apicibus acuminatis vix 
recurvis, externa araneose, cetera glaberrimee, internee minores et
