Scepe indivisis segmentisque ovato-oblongis acuminatis argute serratis 

 membranaceis ; pedunculis breviusculis monocephalis ; capitulo magno 

 (pollicem longo) ; involucro exteriori 8-pbyllo interius adcequante, phyl- 

 lis oblongis seu oblongo-lanceolatis ; ligulis (subpollicaribus) apice in- 

 ciso lobatis ; genitalibus prsesertim stylo longissimo valde exsertis ; 

 acheniis (immaturis) linearibus exalatis nunc flexuoso-curvatis margine 

 hispidulis apice setuloso-coronulatis aristis 2 brevibus seu bi-evissimis 

 fere nudis subterminatis. — Hawaii, Sandwich Islands : also in coll. 

 Remy, no. 278. 



Coreopsis (Campylotheca) Menziesii (sp. nov. Campylotheca 

 australis, Less, pro parte ?) : suffruticosa, fere glaberriraa, corymboso- 

 ramosa ; foliis bipinnati-(vel subternati-) sectis, summis 3 - 5-partitis, 

 segmentis longe anguste linearibus integerrimis ; capitulis parvis (2 lin. 

 longis) plurimis in corymbum digestis breviter pedunculatis ; involucro 

 exteriori breviore ; acheniis angustissime linearibus elongatis glaberri- 

 mis apice calvis rariusve obsolete 1 - 2-setulosis, exterioribus saepe 

 tenuiter subalatis, maturis leviter flexuosis vel tortis. — Variat inflores- 

 centia foliisque (segmentis interdum laciniatis) pi. m. pubescentibus. 

 Ligulas 3 lin. longee. — Hawaii and Maui, Sandwich Islands. Also 

 collected by Menzies, Chamisso ? and Remy. 



Coreopsis (Campylotheca) micrantha (Bidens micrantha, Gaud. 

 Campylotheca micrantha, Cass. C. australis, Less. excl. syn. Forst. 

 & Spreng.) : basi suffruticosa, glabra, paniculato-ramosa ; foliis pinnatim 

 3 - 7-sectis partitisve, summis nunc indivisis, segmentis lanceolatis seu 

 oblongo-lanceolatis grosse argute serratis nunc incisis nunc 3 - 5-fidis 

 venosis ; capitulis parvis (2 lin. longis) plurimis corymbosis ; involucris 

 subfequilongis ; acheniis elongatis angustissime linearibus glabris exa- 

 latis apice nudo aut truncate aut ssepius mucrones vel aristulas 1-2 

 breves Iseves gerentibus, maturis brunneis arete spiraliter contortis. — 

 Sandwich Islands, especially Oahu. Variable in the foliage, which is 

 commonly more dissected than in Gaudichaud's figure. Chamisso 

 seems to have had specimens of 0. Menziesii intermixed with va- 

 rious forms of the present species. The achenium, described by 

 Lessing as " anguste alatum " would appear to belong to the former 

 species. 



Bidens Sandwicensis (Less.): herbacea, glabra ; foliis membra- 

 naceis plerisque trisectis, segmentis ovatis seu ovato-lanceolatis acumi- 

 natis argute serratis, lateralibus petiolulatis vel sessilibus ; capitulis laxe 

 corymboso-paniculatis parvis radiatis ; involucri phylhs linearibus gla-
