vating. They only require to be sown in the open ground in 

 any kind of soil. 



LXI. STANLEYA (in honour of Edward Lord Stanley, pre- 

 sident L. S. and F.R.S. a profound ornithologist.) Nutt. gen. 

 amer. no. 166. B.C. syst. 2. p. 511. prod. l.p. 200. 



LIN. SYST. Tetradynamia, Siliqubsa. Silique roundish, stalk- 

 ed above the torus. Seeds oblong, terete. Calyx spreading. 

 Smooth glaucous erect herbs. Cauline leaves alternate, pinna- 

 tifidly-lyrate or entire. Racemes elongated, terminal. Pedicels 

 bractless, filiform. Flowers yellow. Habit nearly of Brassica 

 on the one hand, and on the other to Clebme. 



1 S. PINNATI'FIDA (Nutt. gen. amer. 2. p. 71.) leaves interrup- 

 tedly pinnatifid. I/ . H. Native of Upper Louisiana at the junc- 

 tion of Point-Creek and the Missouri among broken calcareous 

 rocks. Cle6me pinnata, Pursh. fl. amer. sept. 2. p. 739. Leaves 

 thick, emulating those of a species of Brassica. Flowers yellow, 

 nearly like those of a species of Clebme. The leaves of this 

 species, from their analogy with Brassica, have been tried as an ali- 

 ment, but after it has been cooked it becomes powerfully emetic. 



Pinnatifid-leaved Stanleya. Fl. May. Clt. 1812. PL 3 feet. 



2 S. GRA'CILIS (D. C. syst. 2. p. 512.) upper leaves oblong, 

 entire, sessile, narrowed at the base. . H. Native of North 

 America between Wateree and Longaree. Cleome laevigata, Sol. 

 mss. in herb. Banks. Stems solitary, slender, sparingly branch- 

 ed at the top. Flowers small, yellow, hexandrous. 



Slender- stemmed Stanleya. PI. 1 to 1|- foot. 



3 S. AMPLEXICAU'LIS (Nutt. in Sillim. amer. journ. 5. ann. 

 1822. p. 297.) leaves entire ? stem-clasping ; flowers corymbose ; 

 pods nodding. Native of Eastern Florida in pine woods. Plant 

 smooth, glaucous. Pods 2 or 3 inches long. Flowers yellow. 



Stem-clasping-\ea\ed Stanleya. PL 1 to 1-| foot. 



Cult. The genus Stanleya grows most freely in peat or ve- 

 getable soil. They will thrive in the open border in a rather 

 shady situation. S. pinnatijida may be either increased by 

 dividing the plant at the root or by seeds, and the other two 

 species by seeds only. 



Tribe VIII. 



CAMELI'NEiE (plant agreeing with Camelina in important 

 characters), or NOTORHl'ZE^E (see sub-order II.) -LATISE'P- 

 TiE (latus broad and septum a dissepiment; dissepiment broad.) 

 D. C. syst. 2. p. 513. prod. 1. p. 201. Silicic with concave 

 valves, and with an elliptical dissepiment in its greatest dia- 

 meter (f. 46. r.). Seeds ovate. Cotyledons flat, incumbent, con- 

 trary to the dissepiment (f. 45. i.). The dissepiment in several 

 of the genera is incomplete, sometimes wanting altogether. 



LXII. STENOPE'TALUM (from ravoe, stenos, narrow, 

 and TrtraXov, petalon, a petal; petals narrow.) R. Br. in D. C. 

 syst. 2.. p. 513. 



LIN. SYST. Tetradynamia, Siliculbsa. Silicic elliptical, with 

 concave or flat valves ; cells many-seeded. Style none. Seeds 

 small, somewhat ovate, in 2 rows in each cell. A slender annual 

 smooth upright herb. Leaves scattered, linear, entire. Racemes 

 terminal, elongating as they come to maturity. Pedicels bract- 

 less, filiform, erect, one-half shorter than the pods. Petals 

 narrow. 



1 S. LINE A' RE (R. Br. in D. C. syst. 1. c.) Q. H. Native 

 of south-west coast of New Holland. Herb very slender. Stem 

 filiform, simple or sparingly branched. Leaves 7 or 8 lines 

 long, and half a line broad. Pods 2 lines long and 1 line broad. 

 Petals very narrow. 



Zmear-petalled Stenopetalum. PL 1 foot. 



Cult. The seeds of this plant should be sown in a pot, filled 



with a mixture of sand loam and peat, which should be placed in 

 a hot-bed until the month of May, when it may be planted out 

 in front of a wall, or in any warm situation in the open border, 

 where it will ripen its seed ; but the plant is certainly not worth 

 cultivating, except in botanic gardens.

 what globose, with ventricose valves, opening with the part of the 

 style (f. 46. r.) ; cells many-seeded.' Style filiform. Seeds oblong, 

 not margined. Erect usually branched herbs. Leaves stem- 

 clasping or sagittate, oblong, entire, sinuately-toothed, pinnatifid 

 or serrate. Racemes terminal, many-flowered, elongated after 

 flowering. Pedicels filiform, bractless. Flowers yellow.

2 C. SATI V VA (Crantz. austr. p. 10.) pods cuneated, pear- 

 shaped, with 4 ribs, terminated by a longish style ; leaves almost 

 entire, lanceolate. Q. H. Native throughout the whole of 

 Europe in cultivated fields, chiefly among flax, with whose seeds 

 it is often introduced from one country to another. It does not 

 long propagate itself in Britain spontaneously. It is also found 

 in the island of Cyprus, Tauria, and Siberia, &c. Myagrum
