RANUNCULACEAE 433 
. .2. Aquilegia coccinea Small. Foliage light green. Stems solitary or tufted, 3-8 
dm. tall, erect or ascending, usually branching above, commonly sparingly pubescent about 
the nodes: leaves larger than those of A. Canadensis, otherwise quite similar ; leaflets sub- 
orbicular to cuneate in outline, with 3 main lobes or divisions, glaucous beneath, the seg- 
ments incised or lobed: pedicels minutely glandular-pubescent : sepals ovate-lanceolate, 
acute or short-acuminate, 17-21 mm. long, scarlet: corolla mainly scarlet : spurs 3-3.3 cm. 
long, rather abruptly narrowed below the middle, the lamina yellow: styles not twice as 
long as the ovary: follicles straight, fully 2 cm. long, each tipped with the erect style 
which is much shorter than the body. 
On cliffs and in rocky woods, western Virginia to Nebraska and Alabama. Spring. 
3. Aquilegia australis Small. Foliage palegreen. Stems erect, usually solitary, 3-9 
dm. tall, branching above, finely pubescent, or glabrate in parts: leaves with slender 
petioles, except on the upper part of thestem ; blades twice ternate ; leaflets thin, reniform, 
suborbicular or orbicular-obovate, 1-2 cm. long, glaucescent, especially beneath, crenately 
toothed or lobed, rounded or subcordate"at the base: sepals erect, lanceolate or oblong- 
lanceolate, acuminate, 16 mm. long or less, scarlet: corolla mainly scarlet: spurs 3-3.5 
em. ong, rather abruptly narrowed below the middle: styles more than twice as long as 
the ovary: follicles about 1.5 cm. long, the body about as long as the bristle-like style. 
On limestone cliffs and bluffs, Florida and Texas. Spring. 
10. DELPHINIUM I. 
Annual or perennial herbs, with erect often branching stems. Leaves mostly cauline : 
blades palmately lobed or divided. Flowers in racemes or panicles, showy. Sepals 5, the 
posterior one prolonged into a spur. Petals 2 or 4, small, the two posterior ones spurred, 
the lateral, when present, inconspicuous. Carpels few, sessile, many-ovuled, forming fol- 
licles at maturity. 
Plants annual: carpel 1: petals 2, united. 
Follicles glabrous. 1. D. Consolida. 
Follicles pubescent. ; 2. D. Ajacis. 
Plants perennial: carpels 3: petals 4, distinct. 
Follicles erect : racemes elongated. 
Leaf-segments narrow, the ultimate divisions linear or narrowly oblong. 
Bractlets some distance below the calyx. 
Spur about twice as long as the petals: sepals obovate. 3. D. albescens. 
Spur thrice as long as the petals: sepals oblong. 4. D. macroceratilís. 
Bractiets close under the calyx on the thickened end of the pedicel. 
Sepals greenish or yellowish white : segments of the upper leaves oblong. 5. D. virescens. 
Sepals blue or bluish: segments of the upper leaves narrowly linear. 
Seeds strongly wing-margined. slightly rugose-squamellate. 6. D. Carolinianum. 
Seeds not wing-margined. strongly squamellate. 7. D. vimineum. 
Leaf-segments relatively broad, the ultimate divisions lanceolate. 8. D. urceolatum. 
Follicles widely spreading : racemes short. 9. D. tricorne. 
1. Dek hinium Consdlida L. Plant glabrous, or somewhat pubescent. Stems erect, 
3-8 dm. high, divaricately branched : leaf-blades short-petioled or sessile, all divided 
into narrowly linear cleft or toothed segments: racemes terminal, rather loose, 15-30 cm. 
long: flowers short-pedicelled, blue or white, 2.5-3.5 em. long: spur slender, bent near 
the middle : petals 2, united : follicles erect, glabrous, 8-10 mm. long, each tipped with a 
short slender beak. 
Wetec places, New Jersey and Pennsylvania to Florida. Naturalized from Europe. Locally 
ugitive further northward. Summer. FIELD LARKSPUR. KKIGHT'S-SPUR. LARK-HEEL. 
2. De'phinium Ajàcis L. Similar to D. Consolida, but usually taller, commonly 
5-12 dm. high. Leaves with shorter and more diverging segments: racemes longer, 
mostly 2 4 dm. long, more densely flowered : follicles 12-15 mm. long, pubescent, each 
with a short stout beak. 
Minner. Gide Tees from gardens mainly in the Atlantic States. Naturalized from Europe. 
3. De!phinium albéscens Rydb. Plant finely pubescent, at least above, and some 
what viscid, the roots woody.. Stems 3-15 dm. high: leaves variable ; blades 5-15 dm. 
broad, repeatedly divided into linear segments or those of the lower leaves oblong: ra- 
cemes simple, often becoming 5-6 dm. long: pedicels 1-2 cm. long, erect: bractlets 2-4 
mm. below the calyx or at maturity 6 8 mm. below it: sepals white or nearly so, each 
with a blue spot : spur twice as long as the petals, nearly straight, usually horizontal : lateral 
tals bearded, 2-cleft, the lobes not diverging: follicles cylindric, pubescent, 15-20 mm. 
ong : seed: sharply angled, 1.5-2 mm. long, brown. 
In drs ground, Manitoba to Minnesota, Illinois, Texas and Colorado. Summer.
