Calais eriocarpha: C cyclocarphce et Blgelovii similis; foliis 

 Taraxaci ; acheniis paullo gracilioribus acute costatis ; pappi paleis 

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

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

 pus pi-esent a striking feature. 



Calais aphantocarpha : 0. Bigelovii similis; acheniis paullo 

 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 autumncde. Achenia of Eucalais, 

 the outermost villous. Pappus of Scorzonella, the paleae being re- 

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

 number. 



Stephanomeria lactucina : caule subsimplici e radice perenni 

 tenuiter puberulo ad apicem usque gequaliter 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 pulchellum. 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 

 gradually 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 lines long. 



Stephanomeria? cichoracea: tomento tenui mox evanido gla- 

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

 polycephalis ; foliis caulinis lanceolatis coriaceis rariter pinnatifido- 

 dentatis vel denticulatis, dentil)ns spinescentibus ; involucro circiter 

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

 bus subsquarrosis) constante ; receptaculo favoso ; ligulis brevibus ut 

 videtur roseis ; acheniis liEvibus ; pappo sordido rigidulo bi'eviter plu- 

 mose. — In the collection of Dr. Van Horn, from Fort Tejon, comm. 

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

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

 the leaves fi'om 2 to 6 inches long, rigid, the larger ones furnished,
