38 [94] BOTANY. 
crassa, spongiosa. Herba Californica, glabra. Folia decomposita. Involucrum oligophyllum, 
Involucella 6—8-phylla. 
Cynaprum? (Microrzntra) Bieetovir. Hill sides, near Murphy’s, California; May 16. Stem 3 feet 
or more in height. Lower leaves a foot long, ternately decompound ; segments pinnately incised, 
with linear-lanceolate lobes. Umbels on long naked peduncles. Rays about 12, 2 or 3 inches in 
length. Involucre of 5—6 linear leaves. Involucels somewhat lateral, the leaflets lanceolate 
and reflexed, longer than the flowers. Umbellets monccious, many-flowered ; the male flowers 
mostly central. Petals apparently white. Fruit (immature) about 3 lines long; the ribs very 
indistinct.  Vittee extremely minute, forming an almost uninterrupted citcle around each meri- 
carp. Differs from Cynapium in*its much more compressed fruit, neatly obsolete ribs, and in 
having an involucrum. Very likely the mature fruit would show other differences. 
THASPIUM MONTANUM, Gray, Pl, Fendl. p. 57, and Pl. Wright. 2, p.65. Sandia mountains, . 
New Mexico; October. 
CoNIosELINUM CanavDeENsE, Torr. & Gray, Fl. 1; p. 69. Near Santa Antonita, in mountain 
marshes; October. In fruit. 
DEWEYA? ACAULIS (sp. nov.): humilis; foliis 5—-9-foliolatis e rhizomate repente crasso scapum 
nudum simplicem subsequantibus ; foliolis cuneatis sessilibus acute trifidis quandcque 3-5-fidis 
lobis patentibus acutis integerrimis ; umbella solitaria ; fructu subtereti, valleculis univittatis 
In crevices of rocks near Santa Antonita, New Mexico; October, Of this there are only one or 
two specimens in the collection, with some mature fruit, but no flowers. The genus is alto- 
gether doubtful ; but it may, perhaps, be referred to Deweya until it is better known ; although 
the fruit is but slightly campylospermous, so that the plant should, perhaps, be referred to 
the Seselinew. The seeds and the root-stock have a pleasant aromatic odor, much as in Ligus- 
_ ticum ; from which genus, as well as from Deweya, our plant differs in the single large vittz 
which fill the narrow intervals between the thick and corky, almost winged, rather obtuse ribs. 
Dewsya areuta, Torr. & Gray, Fl. 1, p. 641. Near San Gabriel; March 22; in flower. 
8. foliis triternati-sectis ; involucellis elongatis. D.? (n. sp.) Benth. Pl. Hartw., p. 312; 
Durand, Pl. Prati. p. 89. Mountains near Oakland ; April 5 ; in flower only. The Oakland 
plant must be only a form of D. arguta, with the leaves more divided than usual. 
APIASTRUM ANGUSTIFOLIUM, Nutt. in Torr. & Gray, Fl. 1, p. 644. Hill sides, Napa valley ; 
April 26; plains near San Gabriel; March 23. We dotibt whether A. latifolium is a distinct 
species rosie this. 
ARALIACER. 
ARALIA RACEMoSA, Linn. Spec. 1, p. 273? Bolinas bay, California; April 19; scarcely in fewer. 
The inflorescence is less compound, and the serratures of the leaves are auch coarser than in 
the eastern plant. Very likely this will prove to be a distinct species. 
CORNACEZ:. | 
Cornus Nurrart, pa Bide of Amer. t. 367: Torr. & Gray, Fl. 1, p. 655; Nutt. 
Sylv. 3, p. 51, t. 97. C. florida, Hook. Fl. Bor.-Am. 1, p. 277, (ex parte.) Hill silos and 
ravines, Duffield’s Ranch, Sierra Nevada; May 12; in full flower. This beautiful tree attains 
its highest perfection in lower Oregon, where Mr. Nuttall found it growing seventy feet high. 
The involucral leaves vary in form. They are sometimes nearly as broad as in O. florida. 
- Cornus sesstuis, Torr. (in Durand, Pl. Pratt. p. 89): floribus paullo ante folia late ovata subtus 
pubescentia nascentibus ; involucri foliis acutis ; petalis acuminatis. (Taz. VIII.) Wet ravines 
near Grass valley, California ; May 20; with young fruit. A small tree, (10-15 feet high,) with 
smooth, slender, flexile branches. Leaties 23 inches long and 1} inch wide, dull, closely approx- 
imated towards the extremity of the flowering branches. Umbel 15~20-flowered, appearing
