gerrimis nunc 1 - 3-dentatis seu lobo divaricate* instructis in rachin 

 marginatum decurrentibus ; involucro involucellisque subnuliis ; flori- 

 l us albis; fructus alis disco angusto oblongo paullo angustioribus ; 

 vittis Semini adhasrentibus, lateralibus geminis. — Ostrander's Mead- 

 ows, Yosemite Valley, alt. 8,000 feet, Bolander. Stem 2 or 3 feet 

 high. The nearly full-grown fruit, including the wing, is oval-oblong, 

 about 4 lines long and 2£ wide ; mericarps flat. The stout root not 

 sweet-scented. 



Angelica Breweri : glabra vel tenuiter puberula ; petiolis spatha- . 

 ceo-dilatatis ; foliis triternatis vel triquinatis ; foliolis lato-lanceolatis 

 argute dentatis (dentibus cuspidatis) reticulato-venulosis, lateralibus 

 sessilibus basi insequali hinc srepe adnata ; involucro involucellisque 

 nullis ; floribus albis ; fructu puberulo oblongo, alis crassis angustis ; 

 vittis in valleculis lateralibus quandoque geminis ; semine facie concavo 

 (sectione transversa lunata) doi-so sub vittis sulcato. — Sierra Nevada, 

 near Ebbett's Pass, and on the Big-tree road, alt. 6,000 feet, Prof. 

 Brewer [and near Donner Lake, Prof. Torrey, with mature fruit]. 

 Stem apparently tall and stout. Fruit 4J- lines long, with wings less 

 than half the width of the disk, cellular, and as thick as the edges of 

 the much-flattened seed : the vittas large, adherent on the one side to 

 the groove of the seed into which it is received, on the other to the 

 thin pericarp. 



Ferula Californic a =iLeptotcenia ? Californica,~jSutt. The ma- 

 ture fruit of this, now collected by Bolander [also by Prof. Torrey], 

 but already quite well described by Torrey, in Bot. Whippl. Expl., 

 is traversed with numerous conspicuous, although slender, often anas- 

 tomosing vittaa, and the winged margin is no thicker than in some 

 species of Ferula, to which this plant appears clearly to belong. Its 

 dilated leaflets are in the manner of Narthex. 



Ferula (Leptot^enia, Nutt.) dissecta, with vittse obsolete, as 

 in several Old- World species of Ferula, has usually, and in some of 

 Nuttall's own specimens, an obvious involucre of many bracts ; the 

 fruiting pedicels very short. 



Ferula (Leptot^enia, Nutt.) multifida, if, as is likely, the plant 

 in Spalding's Clear Water collection, has no involucre and longer ped- 

 icels to the flowers and fruit : the latter I have not seen full grown. 

 There are some indications of one or two more species. 



Peucedanum Euryptera (Euryptera lucida, Nutt.), the good 

 figure of which in the Mexican Boundary Survey, t. 27, is not cited
