petals 10 to 14, narrowly obovate; sepals shorter than the petals, reflexed; akenes nearly 
2 lines long, flat, with sharp edges; beak short and curved; heads compact, ovate or 
globular. 
This is by far the most common species, and usually the only one collected by begin- 
ners. It varies greatly. The leaves are sometimes simply three lobed and sometimes 
much cut up. [R&. Bloomeri, Wat., belongs here. See p. 122.] 
6. R. macranthus, Scheele. Stems stout, 2 to 5 ft. high; flowers 14 to 18 lines in 
‘diameter; petals commonly 5 or 6, broadly obovate, shining yellow. 
§ 38. Akenes rough; otherwise as in § 2.

7. R. hebecarpus, Hook. & Arn. Rather slender, more or less hairy; flowers 
minute; petals 5, not more than a line long; sepals hairy, about equaling the petals. 
8. R. muricatus, L, Smooth; flowers 5 or more lines in diameter; akenes large 
and rough, with recurved beaks. Introduced from Europe. 
4 AQUILEGIA, Tourn. CoLumsBine. 
Sepals 5, regular, colored and petal-like; petals 5, produced backward (upward) into a 
long tubular spur; stamens numerous, exserted, the inner ones reduced to thin scales; 
pistils 5; styles slender. Flowers nodding, showy, terminating the branches. 
1. A. truncata, Fisch. & Mey. Stems1 to 3 ft. high; flowers usually red, tinged 
with orange or yellow; leaves usually ternately compound, leaflets lobed. 
5. DELPHINIUM, Tourn. Larkspur. 
Sepals 5, colored and petal-like, very irregular, the upper one prolonged backwards at 
the base into a long spur, which (in our epecies) contains spur-like prolongations of the 
upper pair of petals. Petals 4, small and irregular. Stamens many. Pistils 1 to 5. Erect 
herbs, with palmately-cleft, lobed, or dissected leaves, and racemose flowers. 
1. D. simplex, Dougl. Canescent throughout, with a fine, short, somewhat woolly 
pubescence, rarely smooth; stem stout and strict, 1 to 3 ft. high, leafy; leaves all much 
dissected with linear obtuse lobes, on stout, erect petioles; racemes usually dense and 
many-flowered, the pedicels often short and nearly erect; flowers small, blue, varying to 
nearly white or yellowish; sepals 4 or 5 lines long, about equaling the stout, straight 
spur; ovaries and capsule pubescent. 
2. D. variegatum, Torr. & Gr. Foliage similar to the last, but the flowers much 
larger, on longer pedicels, forming a short, open raceme; ovary and capsule pubescent. 
3. D. decorum. Fisch. & May. Lower leaves 5-lobed, sparingly toothed, the upper 
with narrow divisions. Flowers similar to the last, but the spur is usually longer, and 
the ovary and capsule smooth. 
4. D. Californicum, Torr. & Gr. Stems stout, 2 to 7 ft. high; leaves large, 3 te
