f453. Malacothrix (Leptoseris, Nutt.) sochoides, Torr. $• Gray, Fl. 2. p. 486. 

 Low, sandy hanks of the Rio del Norte : May. (490.) — This is also in Coulter's Cali- 

 fornian collection ; which likewise contains a remarkahle undescrihed species, apparently 

 of this genus.* I notice a singular character in M. sonchoides, M. Coulteri, and espe- 



exsertEe. Achenia lineari-oblonga, teretia, multicostata, erostria, callo sublaterali. Pappus simplex uniserialis, 

 niveus, e setis 14-22 gracillimis eleganter plumosis basi paleato-dilatatis constans. — Herbas perennes glabra ; 

 caule e radice fusiformi tuberosa erecto, ramoso ; foliis integris vel pinnatilobatis, ramis superne longe 

 nudis pedunculiformibus apice subincrassato monocephalis ; capitulis ante anthesin nutantibus; floribus flavis. 

 / 1. P. nuta.ns: gracillima ; foliis angustissime linearibus elongatis e basi subamplexicauli seDsim filiformi- 

 attenuatis integerrimis seu pinnatilobatis, lobis filiformi-subulatis ; involucro cylindrico 20-floro glabrato, squa- 

 mis exterioribus subquinque, interioribus 8 ; acheniis scabridis extimis puberulis; paleis pappi oblongis seta 

 plumosa 5-6-plo brevioribus. — Scorzonella (§ Ptilophora, Torr. <$- Gray, Mss.) nutans, Geyer, Mss. (under 

 Crepis), Hook, in Lond. Jour. Bot. 6. p. 253. — " Dry, sunny, loamy declivities of Spokan and Coeur d'Aleine 

 Mountains ; June. Root nearly as large as the little finger, succulent and almost transparent, full of a bitter- 

 ish milky juice, eaten raw by the Indians." Geyer. Also collected by the Exploring Expedition between 

 Spokan and Colville. — The involucre when young, like the base of the stem, is slightly and minutely glandu- 

 lar-pulverulent ; otherwise glabrous. 



2. P. major (sp. nov.) : foliis spathulato-lanceolatis inferne attenuatis vel in petiolum marginatum angus- 

 tatis integerrimis seu laciniato-dentatis ; involucro campanulato glandulosi-puberulo multifloro, squamis exteri- 

 oribus 8 - 9, interioribus 10- 13 subulato-acuminatis ; ovariis glaberrimis ; pappi setis ima basi tantum scari- 

 oso-dilatatis. — £. laciniata : foliis elongato-Ianceolatis laciniato-pinnatilobatis, supremis integerrimis lineari- 

 attenuatis ; involucro fere glabro. — Clear Water, on the Kooskooskee, Oregon, Mr. Spalding. — Stems a foot 

 or more in height, or in the var. /3. lower. Leaves half an inch or more in width. Heads three fourths of 

 an inch long, larger than in the foregoing species. Mature achenia unknown ; but the fructified ovaries are 

 very short, abrupt at both ends, and perfectly glabrous. The smoother involucre and the more slender foliage 

 of the variety here indicated tend to unite this with P. nutans ; but in the extremely short chaffy base of the 

 setae of the pappus, and in the more numerous involucral scales and flowers, it entirely accords with P. major. 



Allied to this genus, but nearer to Oporinia, is no. 1815 of Hartweg's Californian collection, which before 

 this, probably, has been characterized by Mr. Bentham. 



* Malacotheix? (Malacolepis) Coulteri, Harv. <$- Gray, PI. Coult. ined.) : glaberrima, glaucescens : 

 caule superne ramoso ; foliis lanceolatis oblongisve inferne dentatis seu pinnatifidis basi auriculata amplexi- 

 caulibus, ramealibus cordato-amplexicaulibus acuminatis fere integerrimis ; capitulis (magnis) subcorymbosis 

 breviter pedunculatis ; squamis involucri subglobosi multiflori pluriseriatim imbricatis omnino nisi costa
