CAPPARIDACEAE 489 
3. POLANISIA Raf. 
Annual often clammy-glandular fetid herbs, with erect stems. Leaves alternate, 
without stipules: blades simple or 3-foliolate, the upper ones often reduced. Flowers 
somewhat irregular, in terminal bracted racemes. Sepals 4, imbricated, spreading, some- 
times purplish, deciduous. Receptacle inconspicuous, developed into a solid gland on the 
upper side. Petals 4, hypogynous, deciduous : blades imbricated in aestivation, entire or 
notched at the apex, narrowed into very slender claws, turned toward the appendage on 
the receptacle. Stamens 12-32: filaments filiform, purple, more or less declined, the outer 
ones shorter: anthers introrse. Ovary elongated, viscid-glandular, sessile or short-stalked : 
style filiform, deciduous: stigma depressed. Capsule elongated, silique-like, flattened, 
sessile, 2-valved at the apex. Seeds numerous, conduplicate. CLAMMY-WEED. 
Stamens slightly longer than the petals. 1. P. graveolens. 
Stamens much surpassing the petals. 
Petals 10 mm. long or shorter: filaments 10-12 mm. long. 2. P. trachysperma. 
Petals 12 mm. long or longer: filaments 30-50 mm. long. 3. P. uniglandulosa. 
1. Polanisia gravéolens Raf. Heavy-scented, clammy-pubescent. Stems 1-8 dm. 
tall, branching, rarely spreading : leaf-blades 3-foliolate ; petioles about as long as the ter- 
minal leaflet, slender; leaflets 1.5-3.5 cm. long, the blades elliptic to oblong or ob- 
ovate, obtuse or acutish, entire, nearly sessile: racemes 1-3 dm. long: lower bracts 3- 
foliolate, upper bracts 1-foliolate : sepals oblong, 3 mm. long, abruptly acuminate: petals 
white to pink, 4-5 mm. long; claws shorter than the suborbicular blades, which are 
notched at the apex: stamens hardly longer than the petals: capsules linear-oblong, 3-5 
cm. long, erect: seeds 2 mm. broad, minutely roughened. 
On gravelly or sandy shores, Quebec to the Northwest Territory, New York, Tennessee and Colo- 
rado. Summer. 
2. Polanisia trachyspérma T. & G. Stout, clammy-pubescent. Stems simple or 
branching : leaf-blades 3-foliolate ; petioles longer than the leaflets, stoutish ; leaflets 1—4 
em. long, the blades elliptie, oval or obovate, obtuse or acutish, entire, sessile: racemes 
3-10 mm. long: bracts 1-foliolate, ovate, 0.5-1 cm. long: sepals lanceolate, 5 mm. long, 
ciliate, acuminate : petals 4, 8-10 mm. long ; claws as long as the notched blades or longer: 
stamens long-exserted : capsules erect, linear, 4-6 cm. long, about twice as long as the ped- 
icels : seeds 2 mm. broad, pitted and wrinkled all over. 
In dry soil, Iowa to British Columbia, Texas, Arizona and Nevada. Summer and fall, 
. S. Polanisia uniglandulósa (Cav.) DC. Foliage clammy-pubescent. Stems erect, 
2-7 dm. tall, simple or branching: leaf-blades 3-foliolate ; petioles about as long as the 
leaflets or longer; leaflets 1-3 cm. long, the blades elliptic, oval, ovate or obovate, ob- 
tuse or acutish, entire, sessile or nearly sessile: racemes 0.5-3 dm. long: bracts chiefly 
1-foliolate, ovate : sepals lanceolate, about 5 mm. long, acuminate, glandular and-eiliate : 
petals 4, about 1 em. long; claws longer than the obovate or cuneate notched-blades : 
stamens conspicuously exserted : capsules linear-oblong, erect, 3-7 cm. long, hardly stipi- 
tate, about twice as long as the pedicels: seeds 2 mm. broad, minutely wrinkled. 
In dry soil, along the Rio Grande, Texas and Mexico. Spring to fall. 
4. PEDICELLARIA Schrank. 
Glabrous pubescent or glandular herbs. Leaves alternate, without stipules: blades 
palmately[3—7-foliolate, commonly petioled. Flowers nearly regular, white or purplish, in 
terminal leafy-bracted racemes. Sepals 4, spreading, deciduous. Receptacle depressed- 
hemispheric. Petals 4, hypogynous, often imbricated, entire or crenulate, narrowed into 
slender claws, inserted under the receptacle. Stamens 6: filaments filiform, distinct above, 
united below and adnate to the stalk of the ovary for at least its length. Ovary long- 
stalked : style wanting: stigma depressed. Ovules numerous. Capsule elongated, silique- 
like, somewhat flattened, its stalk apparently jointed at the junction of the filaments. 
Seeds conduplicate, with a rugose or tuberculate testa. [Gynandropsis DC. ] 
1. Pedicellaria pentaphylla (L.) Schrank. Annual, bright green, clammy-pubes- 
Cent. Stem 5-10 dmi? tall, branching : leaf-blades palmately 3-5-foliolate ; petioles longer 
than the leaflets ; leaflets 2-6 cm. long, the blades oval to obovate, acute or short-acumi- 
nate, serrulate: racemes 1-4 dm. long: bracts suborbicular, oval or broadly obovate : 
sepals lanceolate, 4-5 mm. long, acuminate : petals white or pink, 5-10 mm. long: blades
