BOTANY. 1] 
It differs from Nuttall’s description of A. macrophylla, in Gambel’s Plants, by its tomentose 
pedicels, leaves more approximated, denser umbels, and the absence of brown color in its flowers. 
Grows abundantly in river bottoms. Posé creek; August. 
GENTIANZ. 
Eryruraa TRIcANTHA, Griseb. in D. C. Prodr., vol. 9, p. 60, (nova var.) Our plant is inter- 
mediary between E. tricantha and E. Muhlenbergii, all, probably, being varieties of one species. 
A very showy and beautiful little plant. Fort Miller; July. ’ 
-POLEMONIACEA. 
Gana ELONGATA? Stend. in D. C. Prod., vol. 9, p. 30. Our plant differs from D. C.’s, de- 
scription by being scarcely puberulent, although the capitula are densely lanate, by having 
mostly four segments on each side of the leaves, and by the tube of the corolla being much 
exserted. Tulare valley ; August. 
CONVOLVULACE. 
‘CuscuTA suBINcLUSA, (nova species.) Flores dense glomerati subsessiles. Calyx subovatus, 
lobis late ovatis obtusis imbricatis. Corolla primodum tubo cylindrico limbo, patente ; deinde 
germine aucto fauceque marcescente contracta, sublageniformis ; segmenta ovata, latiora supra 
basim, dimidia tubi longitudine. Antherx elongate, infra angulis subsessiles, semi-incluse. 
Filamenta antheris breviora. Squamelle marginibus parallelis maxime ad apicem fimbriatis, 
conniventes. Germen biapiculato-globosuin, bistyle. Styli duplo fere germine longiores, tubi 
longitudine, subineequales, stigmata capitata. 
Flowers subsessile in dense clusters. Calyx subovate, with broadly oval-obtuse and imbri- 
cated lobes. ‘Pube of the corolla cylindrical and afterwards rather lageniform by the increase 
of the germ and shrinking of the fauces. - Lobes of the limb ovate, broadest above the base, 
half the length of the tube.. Anthers subsessile under the dividing angles, half included. 
Filaments shorter than tH@ anthers. Scales parallel-sided, fringed chiefly on the top, conni- 
vent. Germ globose, bi-apiculate with two styles about double the length of the germ, rather 
| unequal ; stigmas capitate. Ona willow. Tejon Pass ; September. 
Comerass 035 Probably the same as the above, but of smaller size, (for want of nourish- 
ment?) and past full florition. Grows on Artemesia dracunculoides, same locality. 
BORAGINE. 
HetrorroriuM ourassavioum, Linn. in D.C. Prodr., vol. 9, p. 558. Muddy localities, Tejon 
valley ; August. 
SCROPHULARIACE, 
ANTIRREINUM cornuTUM, Benth. Pl. Hartw., p. 328. Posé creek; August. 
Antrrruinum Counrerranum, Benth. Var. appendiculatum, (nova var.) Differs from the de- 
scription in D. C. Prodr., vol. 9, p. 529, by the shortness of the peduncles; stem simple, 
erect, glanduloso-pubescent, violet-colored below ; leaves on short petioles, ovate lanceolate, 
smooth ; many sterile setiform branches, bracteate at top, springing from the axils ; flowers 
in a subsecund raceme, almost subsessile. Calyx and corolla strongly pubescent, upper seg- 
ment of the calyx broadly lanceolate, the rest linear lanceolate. Perhaps a new species. 
Posé creek ; August.
