660 SUPPLEMENT— RANUNCULACE^. 



n. ISOPYRUM Linn. hort. Ups., Sf gen. no. 701; Geertn. Jr. t. 65; 



Sclik. handb. t. 153. 



Sepals 5, petaloid, deciduous. Petals 5, small, tubular or conchiform, 

 sometimes wanting. Stamens 10-40. Ovaries 3-20 : ovules few or numer- 

 ous: stigmas lateral. Follicles ovate or oblong, S'-several-seeded, sessile or 

 slightly stipitate, acuminate with the style. Seeds smooth or granulated.— 

 Annual or perennial slender herbs, with 2-3-ternately divided membrana- 

 ceous leaves ; the segments 2-3-lobed. Flowers axillary and tenninal, 

 rather small, white, on slender petioles. 



§ Petals none. — Enemion, Raf. 



1. I. biternatum : petioles auricled at the base ; carpels 3-6, broadly ovate, 

 divaricate, sessile, strongly nerved with 3-4 oblique veins on each side, 

 2-seeded ; seeds obovate, compressed, with a conspicuous cord-like raphe, 

 and a smooth and shining (very minutely pubescent) testa. — I. thalictroides, 

 (var.) Short! cat. fl. Kentucky, 1. p. 8; Hook.! in jour, hot. p. 187, 

 (note). Enemion biternatum, Raf. ! in jour. ph/s. (1820) 2. p. 70. 



Add to the localities already cited ; Middle Florida, Dr. Chapman ! — 

 This is certainly a distinct species, and not an apetalous state of I. thalictroi- 

 des, the young fruit of which we have at length been able to examine : but 

 the structure of the seed in that species is nearly similar to ours, except that 

 the raphe is not prominent, and the ovules vary from 4-6 in number. — The 

 following s]iecies accords with the Enemion of Rafinesque in wanting the 

 petals; while in the form of the carpels, the number of the seeds, and the 

 granulate testa, it approaches the original Isopyrura (Leptopyrum, Reichenb.), 

 I. fumarioides, Linn. 



2. I. occidentale (Hook. & Arn.) : petioles slightly dilated at the base; 

 carpels 6-7, oblong, sessile, at length spreading, marked with numerous 

 transverse veins, 8-9-seeded ; seeds oval, gibbous, with a minutely granu- 

 lated testa. — Hook. Sf Am.! hot. Bcechey, suppl. p. 316. 



California, Douglas .'—Root unknown. Flowers smaller than in the 

 preceding species. 



12. AQUILEGIA, p. 12. 



1. A. Canadensis. — On limestone cliffs, Florida, Dr. Chapman ! — Stem 

 a little pubescent, as is often the case in the Northern States. 



2. A. c(erulea. — Add syn. Hook. Sf Arn. ! bot. Beechey, suppl. p. 317, t. 

 72. (A. macrantha in the plate.) — Flowers very large. 



13. DELPHINIUM, p. 30-33. 



3. D. Californicwn.^-Add syn. D. exaltatum. Hook. Sj- Arn. ! hot. Beech- 

 ey, suppl. p. 317. 



5. D. Menziesii. — Our plant (the D. simplex. Hook. ! ) is not the D. Men- 

 ziesii of De Candolle or Hooker, which is the same with D. pauciflorum, 

 Nutt. Of the present plant we have numerous forms which we cannot 

 distinguish from D. azureum. Our description should therefore be cancelled. 



6. D. azureum. — To var. y. add syn. D. Menziesii P. ochroleucum, 

 Nutt. — The other forms of D. simplex (our D. Menziesii, p. 31), of which
