MONOLOPIA lanceolata, Nutt. Gambel's plant, in Jour. Acad. Nat. Sci. vol. i. 

 p. 175. 



M. Heermannii, spec. nov. Herba tomentosa parvula, caulibus fere e radipe race- 

 mosis, corymbosis, 3 — 5-pollicaribus ; ramis monocephalis ; foliis parallelo-linearibus, 

 fere pollicaribus ; omnibus supra medium rachis 5 — 7-lobatis ; lobis rachique pla- 

 nis, obtusis, superioribus sparse dentatis ; capitulis terminalibus ; involucri late cam- 

 panulati squamis ad medium connatis, segmentis 8, ovato-lanceolatis, valde tomen- 

 tosis; radii floribus 8, ovato-oblongis, involucro plus duplo longioribus, dentibus 

 duobus ad apicem minutissimis ; styli ramulis oblongo-linearibus, basr marginatis ; 

 corollse disci dentibus brevibus, intus asperis. Achsenium maturum non vidi. 



A congener of M. baliice/oUa, Benth. PL Hartw. p. 317. Only one specimen from 

 Mr. Pratten ; but I have four or five from Dr. Heermann, collected at Calaveras. 

 Monolopia Heermannii differs essentially from M.baliioefolia in its leaves being always 

 5 — 7-parted, whilst in the latter they are either entire or 3-lobed. 



MALACOTHRIX tenuifolia, Torr. and Gr. Fl. Am. vol. ii. p. 487. Leucoseris 

 tenuifolia, Nutt. 



MACRORHYNCHUS retrorsus, Benth. PL Hartw. p. 320. " Planta perennis, laxe- 

 piloso-lanata vel demum glabrescens, foliis lineari-lanceolatis, retrorsum pinnatifidis ; 

 involucri squamis exterioribus apice foliaceis, interioribus lineari-lanceolatis, rostro 

 achseniis plus triplo longiore. 



Same size as M. troximoides, with larger heads. Leaves 4 — 6 inches long, very 

 acuminate, rachis larger, segments 4 — 8 on each side, lanceolate, retrorse, and all, as 

 well as the apex of the leaves, terminating in a glandular callus, and some having a 

 tooth at the base. Immature achenia with prominent ribs, beak 5'" long." 



M. heterophyllus, Nutt. Mr. Pratten's specimens are larger than those collected 

 in Oregon by Mr. Nuttall, who represents this plant as a dwarf species. They are of 

 the same size as those I have received from Dr. Torrey, collected by Col. Fremont; 

 but I have others from Calaveras (Dr. Heermann's) that are not less than a foot high, 

 with flowers from li to li" in diameter. 



CAMPANULACE.E. 



CAMPANULA pkenanthoides, spec. nov. Elata ramosa, foliis inflorescentise sessi- 

 libus, lanceolatis, acutis, basi latioribus, marginis infra medium utrinque bidentatis. 

 Floribus coeruleis, subnutantibus, 3 — 5-paniculatis, spicam laxam inferne ramulosam 

 constituentibus ; calycis tubo globoso-truncato ; corollis campanulatis, profunde divisis, 

 lobis lanceolatis ; stylo exerto, reflexo ; stigmate clavato, ramis tribus erectis brevibusque 

 ad summum instructo. GSstivatio prenanthidis.
