35. ANGELICA L. Angelica. 



Stout perennials, with a woody root. Leaves ternate-pinnately or pinnately 

 compoimd, usually with broad segments. Flowers white, or rarely greenish 

 j-ellow or purplish, in large imibels. Bracts scanty or none, in one species foU- 

 aceous; bractlets small or wanting. Cah"x-teeth mostly wanting. St^-lopodium 

 conic. Fruit flattened dorsally, ovate or oblong, glabrous or pubescent, with a 

 prominent crenulate disk. Dorsal and intermediate ribs strong, the lateral ones 

 broadly winged; wings distinct from those of the other carpel. Oil-tubes one to 

 several in each interval, or indefinite, 2-10 on the cormnissural side. Seed-face 

 plane or sHghtly concave. 



Oil-tubes mostly solitary in the intervals, not continuous around the seed; rays of the 

 umbels ascending. 

 Involucre and involucels of several foliaceous, lacerately toothed bracts. 



1. -4. Dawsoni. 

 Involucre none or consisting of 1-2 smaU bracts. 

 Involucels of many bractlets. 



Bractlets lanceolate, acimiinate. 2. A. Grayi. 



Bractlets Linear-filiform. 3. A. genuiflexa. 



Involucels none, or of a few linear-subulate or filiform bractlets. 

 Plant glabrous up to the inflorescence. 

 Fruit glabrous or nearly so. 



Fruit 3-3.5 mm. long: oil-tubes soUtary in the interval, except in the 



lateral ones, where they are usually in pairs. 4. A. leporina. 



Fruit over 5 mm. long: oil-tubes solitary in aU the lnter*-als. 



Leaves once pinnate, or the lower primary divisions short-petioled 



and again pinnate. 5. A. pinnata. 



Leaves temate and then pinnat«, the lower primary divisions long- 

 petiolate. 

 Di\-isions of the leaves and their teeth lanceolate, acuminate. 



6. A. arguta. 

 Divisions of the leaves and their teeth ovate, acute or obtuse. 



Teeth of the leaves acute: plant perfectly glabrous.

sUghtly pubescent on the sheaths, leaf-stalks, and veins 

 beneath. 8. A. Piperi. 



Fruit hispid: leaves twice compound. 



Rays numerous: leaflets broadly ovate or obovate; pedicels longer than 



the fruit. 9. A. dilatata. 



Rays few: leaflets lanceolate or linear-lanceolate; pedicels and fruit 

 subequal. 10. A. Kingii. 



Plant more or less scabroas or pubescent, at least on the sheath, leaf-stalks, 

 and veins beneath. 

 Fruit glabrous; leaves sparingly short-hispid on the sheaths, petioles, and 



veins. S. A. Piperi. 



Fruit hispid or rough-puberulent : leaves rough-pubescent. 



OU- tubes solitary in the intervals; pedicels and fruit rough-puberulent.
