of the Galapagos Archipelago. 207 
Also a very distinct species, with much shorter leaves than L. tenuifolia, 
and shorter cilia at the base: the peduncles too are more abbreviated and 
stouter. 
153. AaERATUM CONYZOIDES, Linn. Sp. Pl. 1175. DeC. Prodr. vol. v. p. 108. 
Hab. Charles Island, Charles Darwin, Esq. A very widely-diffused native of the tropics, 
both in the old and new world. Some of the specimens have no pappus whatever, 
and in others the pappus is shorter than in the ordinary state of the plant. 
154. ERIGERON TENUIFOLIUM, Hook. fil.; fruticosum, ramis inferné denudatis 
cicatricosis, foliis patentibus angusté linearibus acuminatis basi ciliatis, 
capitulis terminalibus pedunculatis subeorymbosis, pedunculis folio bre- 
vioribus, involucri obconici squamis linearibus pluriserialibus. 
Hab. Charles and James Islands, Charles Darwin, Esq. 
Rami lignosi, teretes, crassitie penne anatinze, cicatricibus foliorum delapsorum subannulati, 
superné subfastigiatim di- trichotomé ramosi, cortice pallidé fusco. Folia versus apices 
ramulorum fasciculata, patentia, 1 unc. longa, vix 4 lin. lata, glaberrima v. parcé pilosa, 
marginibus subrecurvis basi ciliatis in ramum subdecurrentibus. Pedunculi plurimi, 
1 unc. longi, validi, in axillis foliorum summorum, inferiores longiores, unde corymbosi, 
bracteati, bracteis in squamas involucrales gradatim desinentibus. Capitula obconica 
v. subeampanulata, basi angustata, } unc. longa. Involucri squamze plurime, gradatim 
longiores, angusté lineares, subscariose, post anthesin patentes v. reflex. Recepta- 
culum pauló convexum, papillosum. Flores radii pauci, ligula oblonga revoluta 3-nervi ; 
disci tubo parcé piloso, dentibus glanduloso-incrassatis. Stamina ecaudata. Stylus 
fl. radii ramis linearibus, obtusis, marginibus incrassatis; disci brevioribus, cono dorso 
glanduloso terminatis. Achznia compressa, subtrigona, puberula. Pappus 1-serialis, 
rigidus; setis inzequalibus, scabrido-pilosis, flavidis. 
This species and the following nearly agree with the character of Solidago, 
but the habit and inflorescence are entirely different, and the involucres are 
neither cylindrical nor elongated. The scales of the involucre are more imbri- 
cated and conical than in Erigeron, the flowers of the ray fewer and probably 
yellow. Mr. Bentham, who has had the kindness to inspect both the Composite 
and Leguminose of this curious collection, agrees with me as to the propriety 
of including these in Erigeron, though they form a group in that genus quite 
distinct from any other.
