Small branching glabrous annual with dissected loaves. Flowers small, white, 

 in irregularly compound umbels. Rays and pedicels unequal. Involucre and 

 involueels none. Calyx-teeth wanting. Fruit somewhat laterally compressed, 

 elliptic-cordate, more or less tuberculate. Oil-tubes solitary in the intervals, 2 

 on the face. Seed-face narrowly concave. (Apium, Celery, and aster, Latin

1. A. angustifolium Xutt. Erect, di- or tri-chotomously branched from the 

 base, 4 to 8 (or 15) in. high; leaves opposite below, twice or thrice ternately 

 dissected into linear segments '._> to 1 in. long; umbels sessile in the forks or 

 opposite the upper leaves, consisting of 2 or 3 umbellets borne on unequal rays 

 (1 in. long or less), and of 1 or 2 usually sessile or sometimes pedieeled flowers 

 in the center; umbellets 3 or 4-flowered, the pedicels unequal (4 1 /> lines long or 

 less) or 1 flower sessile; fruit cordate, broader than high, less than 1 line long. 

 papillate-roughened all over; ribs inconspicuous. 



Dry mountain slopes of the Coast Ranges and Sierra Nevada; frequent. 

 Apr.-May. A plant of peculiarly irregular inflorescence. 



10. CONIUM L. 



Tall branching biennial with dissected decompound leaves. Flowers white, 

 in compound umbels. Involucre and involueels small. Calyx-teeth obsolete. 

 Fruit broadly ovate, somewhat laterally flattened. Ribs prominent. Oil-tubes

 1 to IVt in. long; bractlets ovate-lanceolate, commonly 3; fruit 1 \ ■_. lines long, 

 shorter than the pedicels. 



Naturalized from Europe in shady or moist ground. Widely distributed. 

 Poisonous plant, all parts toxic, although preparations from the leaves are 

 sometimes inert. 



11. VELAEA DC. 



Subglabrous perennials with thick yellow elongated odorous taproots. Leaves 

 mostly radical, pinnatelv or in ours ternately compound. Ours usually without 

 involucre, the involueels in our species of few small lanceolate bracts. Flowers 

 yellow, in compound umbels. Calyx-teeth mostly small. Fruit oblong or 

 orbicular, glabrous or pubescent, somewhat laterally compressed, with prom- 

 inent equal ribs. Oil-tubes conspicuous. 3 to (i in the intervals, 4 to 10 on the 

 face. Carpophore undivided. Seed-face strongly involute, enclosing a central 

 cavity. (Sebastin Eugene Vela, student of the Fmbelliferae.)
