Calais eriocarpha: C. cyclocarphce et Bigelovii similis; foliis 

 Taraxaci ; acheniis pauUo gracilioribus acute costatis ; pappi paleis 

 (quandoque 3-4) ovalibus integerrjmis extus lanatis arista sesqui- 

 brevioribus. — Nipoma, on low hills. The woolly paleae of the pap- 

 pus present a striking feature. 



Calais aphantocarpha : C. Bigelovii similis ; acheniis pauUo 

 gracilioribus ; pappi paleis 5 minimis deltoideis subito in aristam 

 tenuem scabram achenio longior productis. — Bushy Knob, southeast 

 of Monte Diablo. Leaves and scapes (one to two feet high) and the 

 whole aspect not unhke Leontodon autumnale. Achenia of Eucalais, 

 the outermost villous. Pappus of Scorzonella, the pale£e being re- 

 duced to a mere basal dilatation of the slender awn, but only five in 

 number. 



Stephaxomeria lactucixa : caule subsimplici e radice perenni 

 tenuiter puberulo ad apicem usque lequaliter folioso oligocephalo ; foliis 

 lanceolatis seu linearibus parce spinuloso-dentatis vel integerrimis ; ca- 

 pitulis subcorymbosis ; involucri (semipollicaris) squamis lanceolatis 

 subimbricatis ; floribus circiter 10. — Dry hill near Big-tree Road in 

 the Sierra Nevada, alt. 6,000 feet. A somewhat anomalous and large- 

 flowered species of this genus, with the aspect rather of a reduced form 

 of Midgedium pulcheUum. Stem not much branched. Leaves from 

 1^ to 2^ inches long, sessile, not clasping. Scales of the involucre 

 somewhat broadly lanceolate, the outer ones of various lengths, and thus 

 gi'adually passing into the inner ones, making the involucre somewhat 

 imbricated. " Flowers delicate rose-color." Mature achenia not seen ; 

 but the ovaries wholly as in Stephanomeria. Pappus bright white, 4 

 or 5 hues long. 



Stephanomeria ? cichoracea : tomento tenui mox evanido gla- 

 brata ; caule rigido elate, ramis virgatis superne nudis racemoso-oligo - 

 polycephalis ; foliis caulinis lanceolatis coriaceis rariter pinnatifido- 

 dentatis vel denticulatis, dentibus spinescentibus ; involucro circiter 

 12-floro e squamis plurimis lanceolatis gradatim imbricatis (exteriori- 

 bus subsquarrosis) constante ; receptaculo favoso ; ligulis brevibus ut 

 videtur roseis ; acheniis hisvibus ; pappo sordido rigidulo breviter plu- 

 mose. — In the collection of Dr. Van Horn, from Fort Tejen, coram, 

 to Professor Brewer. A plant of wholly doubtful genus, with the 

 habit of Cichoriiim Intyhus, but more leafy up the stems or branches; 

 the leaves from 2 to 6 inches long, rigid, the larger ones furnished,
