the coast, where it is probably naturalized from Europe, but occasionally occurring 
as an apparently indigenous plant in the interior, 
++ ++ Style long and attenuate, stigmatic at the tip, persistent or the upper part deciduous. 
= Petals 5: early root-leaves onl y 3-parted, later ones 3 to 5-foliolate. 
6. R. septentrionalis Poir. Low, hairy or nearly glabrous: stems ascending, or 
in wet ground some of them procumbent or forming runners: leaves 3-divided, the 
divisions all stalked, broadly wedge-shaped or ovate, unequally cleft and cut: petals 
obovate : achenes strongly margined, with a stout straightish beak, (R. repens of most 
American authors)—Moist or shady places, 
7. R. fascicularis Muhl. Low, pubescent, with close-pressed silky hairs: root a 
cluster of thickened fleshy fibers: radical leaves appearing pinnate, the long-stalked 
terminal division remote from the (usually) sessile lateral ones and 3 to 5-divided or 
parted into oblong or linear lobes : petals (often 6 or 7) spatulate-oblong: achenes 
scarcely margined, with a slender, straight, or rather curved beak.—Our earliest 
“buttercup,” and occurring throughout the State, 
== Petals 7 to 16: no creeping or procumbent stems. 
8. R. macranthus Scheele. Hirsute: stems erect, or declining, 3 to 9 dm. long . 
leaves nearly as in R. septentrionalis, but many 5-divided: petals 8 to25 mm. long, 
obovate tooblong: achenes numerousin a large head, ovate or orbicular, conspicuously 
thin-edged, at length with a rather short and broad flat-subulate beak.—Low ground 
throughout Texas, where it seems to be the most characteristic and common « but- 
tercup.” 
6. AQUILEGIA Tourn. (COLUMBINE. ) 
Perennial herbs, with ternately compound leaves and lobed leatlets, 
large and showy flowers terminating the branches, sepals and petals 
colored alike, the latter produced backward into large hollow spurs 
much longer than the sepals, and erect many-seeded pods, 
1. A. chrysantha Gray. Tall, 6 to 12 dm, high, many-flowered: flowers bright 
yellow throughout: sepals lanceolate- oblong, hardly exceeding 2.5 em. in length, a 
little longer and not broader than the limb of the petals: spurs very slender, over 
5 em. long.—In the mountains of western Texas, where it is the most abundant 
“‘columbine” and one of the showiest of flowers, 
2, A.longissima Gray. Somewhat pubescent, with silky hairs, 9 dm. high: flowers 
“lake, white, and straw color:” sepals lanceolate, broadly spreading, 2.5 to 3 em. long: 
petals narrower than in the last, spatulate, about 18mm. long, the claw opening by a 
narrow orifice into the very slender elongated spur, which is 12 em. long or more.—A 
Mexican columbine, but discovered by Dr. Havard in the upper cafions of the Chisos 
Mountains. 
7. DELPHINIUM, Tourn. (LARKSPUR. ) 
Perennial herbs (our species), with palmately divided or cut leaves, 
a terminal raceme of blue flowers, 5 irregular petal-like sepals (the 
upper one prolonged into a spur), 4 irregular petals (the upper pair 
with long spurs which are included in the calyx spur), and many-seeded 
pods. 
1. D. Carolinianum Walter. Stem 3 to 6 dm, high, slender, often softly pubescent : 
leaves deeply 3 to 5. parted, the divisions 2 to 3 times cleft; the lobes all narrowly 
linear: raceme strict: flowers sky-blue or whitish : Spur ascending: pods erect, (D, 
azureum Mx,)—In the valleys of southern and western Texas.
