3. EUTOCA, R. Br. Eutoca. 
Placentae each 4 - many-ovuled ; the pod 8 - many-seeded: 
otherwise as in Phacelia. Chiefly annuals. (Name from cvtokos , 
fruitful , in allusion to the more numerous seeds than in Phacelia.) 
1. E. parviflora, R. Br. Low, diffuse, somewhat hairy; 
stems slender ; leaves pinnatifid; the uppermost 3-cleft or sometimes 
entire, sessile; lobes of the lower ovate, of the upper oblong, entire ; 
raceme solitary, elongated; fruiting pedicels much longer than the 
calyx; stamens about the length of the (pale blue) corolla; ovary 
12- 16-ovuled. (Phacelia parviflora, Pursh. Cosmanthus, DC.) — 
River-banks, Penn, and southward. April-June. — Plant 5'-8' 
high, with small flowers. 
Order 74. POEEMONIACEiE. (Polemonium Fam.) 
Herbs, with alternate or opposite leaves, regular 5 -me-

volute in the bud, a S-celled ovary and 3-lobed style; the 
pod 3- celled, 3-valved, loculicidal, few—many-seeded ; the 
valves usually breaking away from the triangular central 
column. — Seeds between anatropous and amphitropous, the 
coat frequently mucilaginous when moistened and emitting 
spiral threads. Embryo straight in the axis of copious hard 
or fleshy albumen. Calyx 5-cleft, persistent. Corolla with 
a 5-parted border. Stamens often unequal or unequally in¬ 
serted on the tube of the corolla. Flowers cymose-pani- 
cled. (Only two genera are indigenous in the Northern 
States, but several North American species of Giiia, &c., 
are becoming common in cultivation.) 
1. POLEMONIUM, Tourn. Greek Valerian. 
Calyx bell-shaped. Stamens equally inserted at the summit of 
the very short tube of the open-bell-shaped corolla; filaments slen¬
