 Hab, Albemarle Island, Charles Darwin, Esq. 



Herba spithamaea, vage ramosa, ramis ascendentlbus gracillimis. Folia pauea, | unc. longa. 

 Pedunculi filiformesj 2-3-unciales. Capitula vix 2 lin. lata. Flores radii pauci, 1-seriati ; 

 disci tubulosi, nervis incrassatis. Receptaculuin planum, paleis lanceolatis onustum. 

 Stylus fl. radii ramis obtusis, fl. disci ramis appendicibus valde elongatis terminatis. 

 Achaenia laevia, 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 angust^ lineari-spathulatis acuminatis integerrimis 

 V. remote serratis marginibus revolutis crispatulo-undulatis, capitulis

Specimen mancum 4-pollicare basi validum lignosum; ramis gracilibus herbaceis. Folia 

 |-1 unc. longa, vix 1| lin. lata, integerrima, rariiis remote argute serrata. Capitula ^ 

 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. 



UMBELLIFERiE.

174. Helosciadium leptophyllum, DeC. Prodr. vol. iv. p. 105. 

 Hab. James Island, Charles Darwin, Esq. 



These specimens are starved and very diminutive. It is more than pro- 

 bable that this, the former and H. ranunculi/olium, DeC, will all merge into 

 one species.
