660 BALSA MINACEAE 
5. Geranium Caroliniànum L. Annual or biennial. Stem simple below and erect, 
or branched at the base, the branches ascending or spreading, more or less glandular-pubes- 
cent: leaf-blades 3-6 cm. broad, reniform or orbicular-reniform in outline, slightly 
a et the main segments cleft or parted into oblong or linear-oblong lobes: peduncles 
and pedicels relatively short, thus causing the flower-clusters to be somewhat congested : 
outer sepals ovate, sometimes broadly so, 6-10 mm. long, each with a rather long awn-tip: 
petals pink or whitish, about as long as the sepals: carpel-bodies 3-3.5 mm. long, pilose 
with erect hairs: style-column 12-18 mm. long, with somewhat spreading often glandular 
hairs: seeds reticulated. 
In dry soil, southern British America and the United States. Also in Mexico and Bermuda. 
Spring and summer. 
6. Geranium Langloisii Greene. Resembling G. dissectum in habit, but stouter : 
leaves with relatively larger and less finely cleft blades: inflorescence not congested as in 
G. Carolinianum, copiously villous-hirsute, but the glands of the hairs inconspicuous : 
corolla pale rose-purple: seeds reticulated. 
In sandy soil, southern Louisiana. Spring. 
7. Geranium maculatum L. Stems erect, 2-6 dm. tall, from thick astringent root- 
stocks, pubescent with spreading or retrorse hairs, forked above. Leaves mainly basal ; 
blades 5-12 cm. broad, reniform or suborbicular in outline, deeply 3-7-parted, the segments 
toothed, incised or lobed ; petioles of the basal leaves several times longer than the blades : 
cymes open: peduncles 2-flowered : sepals 5, elliptic or elliptic-lanceolate or oblong, 8-10 
mm. long, awn-tipped, ciliate, villous especially near the edges : corolla rose-purple, 2.5-3 
cm. broad: petals 5, entire, pubescent at the base: carpel-bodies 3-3.5 mm. long, hirsute: 
style-column 2-3 cm. long, finely pubescent : seeds minutely wrinkled. 
Inrich woods, Newfoundland to Manitoba, Georgia, Alabama and Nebraska. Spring and summer. 
2. ERODIUM L Her. 
Annual or perennial, caulescent or scapose herbs, or shrubby plants. Leaves opposite 
or alternate, subtended by stipules: blades lobed or pinnately dissected, petioled. Flowers 
solitary or umbellately disposed at the end of axillary peduncles. Sepals 5, imbricated. 
Petals 5, imbricated, alternating with 5 glands. Stamens 5, alternating with 5 staminodia : 
filaments slender. Ovary 5-lobed, beaked: styles united. Capsule 5-lobed, each lobe 
separating elastically from an axis and rolled back with the curling style. Seed solitary 
in each cavity. Endosperm wanting. STORK’S-BILL. PINE NEEDLE. 
Leaf-blades pinnately divided : petioles pubescent with spreading hairs. 1. E. cicutarium. 
Leaf-blades palmately lobed : petioles densely puberulent. 2. E. Texanum. 
1. Erodium cicutàrium (L.) L'Her. Annual or biennial, villous, somewhat viscid. 
Stems simple, or branched at the base ; branches tufted, erect or ascending, usually forked 
above: leaves often numerous; blades pinnately divided, 5-16 cm. long, the segments 
finely and sharply pinnatifid ; petioles shorter than the blades, or upper blades sessile : 
peduncles longer than the subtending leaves, topped by a 2-12-rayed umbel-like cyme : 
sepals oblong, 4-5 mm. long, apiculate: corolla pink or purple, 8-10 mm. broad : etals 
5, oblong-obovate, hardly longer than the sepals, entire : carpels pubescent, 4-6 mm. long ; 
beak slender, 2-4 cm. long. i 
In waste places, Nova Scotia’to Oregon, New Jersey, Texas and Mexico. Adventive or naturalized 
from Europe. Spring to fall. 
2. Erodium Texànum A. Gray. Annual or biennial, strigose, not viscid. Stems 
more or less diffusely branched at the base ; branches spreading, 5-31 cm. long, usually fork- 
ing: leaves several; blades ovate in outline, palmately lobed, 1-3 cm. long, cordate, the 
lobes toothed or incised ; petioles longer than the blades, except the upper ones: pedun- 
cles longer than the subtending leaf, topped by a several-rayed umbel-like cyme : sepals 
elliptic, 6-10 mm. long, puberulent, awn-tipped : petals cuneate or obovate-cuneate, often 
ed twice as long as the sepals : carpels 7-9 mm. long, silky ; beak slender, 3.5-7.5 cm. 
ong. 
In dry soil, Texas to California and Lower California. Spring and summer.
