Hab. Albemarle Island, Charles Darwin, Esq. 
Herba spithamzea, vagé ramosa, ramis ascendentibus gracillimis. Folia pauca, ! unc. longa. 
Pedunculi filiformes, 2-3-unciales. Capitula vix 2 lin. lata. Flores radii pauci, 1-seriati ; 
disci tubulosi, nervis incrassatis. Receptaculum planum, paleis lanceolatis onustum. 
Stylus fl. radii ramis obtusis, fl. disci ramis appendicibus valdé elongatis terminatis. 
Acheenia lzvia, integumento crassiusculo non crustaceo. 
Much the most slender species of the genus with which I am acquainted. 
172. APLOPAPPUS LANATUS, n. Sp.; fruticulosus, totus arachnoideo-lanatus, 
foliis membranaceis angusté lineari-spathulatis acuminatis integerrimis 
v. remoté serratis marginibus revolutis crispatulo-undulatis, capitulis

Specimen mancum 4-pollicare basi validum lignosum; ramis gracilibus herbaceis. Folia 
3-1 unc. longa, vix 1} lin. lata, integerrima, rariüs remote arguté serrata. Capitula 1 
unc. longa, e floribus radii inconspicuis primo visu discoidea, Receptaculum alveola- 
tum, fimbrilliferum. 
A very distinct species, allied to Heterotheca in the flowers of the ray 
being neuter, very few in number, and incompletely developed.

These specimens are starved and very diminutive. It is more than pro- 
bable that this, the former and H. ranunculifolium, DeC., will all merge into 
one species. |
