CiusTATELLA. CAPPARIDACE/E. 123 



herbarium of Maj. Le Conte, which approaches in the foliage and the very unequal 

 petals to Cristatella; a curious genus, which should perhaps be considered a section 

 of Polanisia, if indeed all these genera ought not to be restored to Cleome, accord- 

 ing to the opinion of Brown. 



L P. graveolens (Raf.): viscidly pubescent and glandular; leaves 3-loli- 

 olate; leaflets (and bracts) oblong, shorter than the petiole; sepals (purplish) 

 soraewhat unequal; petals cuneate, emarginate; stamens mostly 10 or 11 ; 

 style shorter than the ovary ; pods broadly lanceolate, turgid, attenuate at the 

 base, reticulated, rough with a glandular pubescence. — Raf. I. c. ; DC.

On the gravelly banks of rivers and lakes, from L. Champlain ! and On- 

 tario ! to Arkansas ! June-Aug.— Branching, 6-18 inches high. Raceme 

 many-flowered. Sepals glandular on the back. Petals yellowish-white : 

 claws filiform. Filaments purplish. Nectary concave, truncate, very short. 

 Style at length deciduous. — Odor of the plant strong and unpleasant. 



2. P. tenuifolia : viscid-glandular ; leaves 3-foliolate, nearly glabrous ; leaf- 

 lets (and bracts) fihform-linear, longer than the petiole ; petals very unequal, 

 suborbicular, entire, on short claws; stamens 9-11; style longer than the 

 ovary ; pods linear, terete, niinutely reticulated, glabrous. — Cleome tenuiib- 

 lia, herb. Le Conte. 



Georgia, Le Conte .'—Stem afoot high, branched, slender. Leaflets about 

 an inch long. Raceme few-flowered ; pedicels filiform. Sepals glabrous, 

 nearly equal. Filaments nearly equal. Nectary minute, cuneiform, emargi- 

 nate. Style persistent. 



5. CRISTATELLA. Nutt. in jour. acad. Philad. 7. p. 85. t. 11. 



Sepals somewhat united at the base, spreading. Petals 4, on filiform 

 claws, fimbriate-toothed or laciniate ; the two lower much smaller. Torus 

 minute, bearing a conspicuous tubular and truncate petaloid nectary between 

 the ovary and the upper sepal. Stamens 6-14 : filaments nearly equal, de- 

 clined. Ovary declined: style filiform. Pod linear, stipitate. — Annual 

 minutely viscid-glandular 3-foliolate herbs, with the habit of Polanisia 

 tenuifolia. Leaflets narrowly linear, longer than the petiole. Raceme 

 few-flowered, leafy : pedicels filiform. Flowers small, white or pale yel- 

 low. 



1. C. erosa (Nun.) : stamens 10-14; petals white; lamina of the lower 

 ones lacin lately parted ; sepals acute. — Nnft. ! I. c. p. 86. t. 11. 



On sandy hills near Red River, Nuttall ! and near Fort Towson, Dr. 

 Leavemoorth! June-July. — Rather slender, branching, 8-14 inches high. 

 Sepals oblong-lanceolate, shorter than the claws of the petals. Superior pe- 

 tals very broadly cuneiforai, sparingly lacerate-toothed : lower ones cuneiform, 

 cleft nearly to the base of the lamina ; segments linear, slightly dilated and 

 cleft or toothed at the apex. Nectary about the length of the smaller petals, 

 yellow, tubular, toothed at the summit (cleft on the side next the ovary, ac- 

 cording to Nuttall; but in the specimens from Dr. Leavenworth, the tube is 

 undivided). Pod narrowly linear, slightly torulose, many-seeded, ascending, 

 much longer than the stipe, crowned with the slender style. Seeds circinate, 

 minutely roughened.
