almost subulate. Flowers about as large as the preceding species. Style
narrowly linear, pubescent nearly the whole length of the upper surface.
Legume large, glabrous.—Allied to the preceding, but quite distinct.
4. ASTROPHIA. Nutt. mss.
Calyx campanulate, 5-cleft; the 2 upper segments a little shorter. Style
flat, linear, pubescent along the inside. Legume broadly oblong, compressed,
few-seeded.—A perennial herbaceous silky-villous plant. Stem erect, branching.
Leaves pinnately 4-6-foliolate; the petiole terminated by an abortive
leaflet. Peduncles axillary, few-flowered.
A. littnralis (Nutt.! mss.)
“ Sand hills near the estuary of the Oregon.—Roots slender, horizontal.
Plant thickly clothed with a soft silky gray pubescence, branching from the
base, with numerous infertile axillary branchlets. Stipules more than twice
the size of the leaflets, oblong, inequilateral and somewhat produced at the
base on one side, but scarcely semihastate. Leaves small. Leaflets 2-3
pairs, linear-spatulate, about half an inch long and 1} line wide ; the terminal
leaflet scarcely one-fourth the size of the others (appearing like a slight
expansion of the apex of the petiole). On some of the branches the lowest
leaves are 3-cleft, instead of pinnate. Racemes pedunculate, about 5-flower-
ed. Perfect flowers not seen. Segments of the calyx lanceolate, acute,
about as long as the tube. Ovary 8-10-ovuled. Legume about 14 inch long
and half an inch wide, villous, with 2-3 perfect seeds. Seeds globose, brown,
with a linear semicircular hilum.—The plant has somewhat the habit of
Orobus, but the pod is flat and broad.” Nuttall.
T ribe II. PHASEOLEiE. Broun; Benth.
Corolla papilionaceous. Stamens diadelphous (9 & 1), or rarely
somewhat rnonadelphous. Disk usually a membranous sheath surrounding
the base o f the ovary. Legume continuous, never separating
into joints, but often torose and with cellular partitions between
the seeds, dehiscent. Seeds usually reniform, convex or compressed.
Radicle incurved.—Twining (sometimes erect or prostrate) herbaceous
or shrubby plants. Leaves usually pinnately trifoliolate (rarely
reduced to a single leaflet), sometimes unequally pinnate, stipellate.
Inflorescence axillary, seldom terminal, racemose or somewhat pani-
cled.
Subtribe 1. E uphaseoleje, Benth.—Ovary with several ovules. Inflorescence
racemose with the pedicels usually aggregated on alternate knobs.
Vexillum usually biappendiculate at the base. Style often indurated above
the middle. Cotyledons thick, nearly unchanged in germination, and either
rising out of the ground or remaining beneath the surface.
1. Leaves pinnately trifoliolate.
5. PHASEOLUS. L in n .; DC. prodr. 2. p. 390; Benth. Leg. gen. p. 73.
Calyx campanulate, 5-toothed or 5-cleft; the 2 upper teeth often more or
less united. Keel with the stamens and style spirally twisted or circinate.
Legume linear or falcate, more or less compressed, or somewhat terete, many-
seeded. Hilum small, oval-oblong, naked, or rarely with a small membranaceous
caruncle.—Herbaceous or suffrutescent, twining or trailing plants.
Leaflets manifestly stipellate. Pedicels usually in pairs. Kidney-Bean.

shorter than the tube: legume compressed, broad and Jalcate.—D re-

1. P. perennis (Walt.): perennial; leaflets ovate, acuminate, palmately

longer than the leaves; legumes pendulous.— Walt. Car.p. 182 ; Pursh,

Rocky woods and borders of swamps, Canada! to Florida ! and west to
Louisiana! July-Aug.—Stem 4-10 feet long, pubescent, climbing over
small shrubs or trailing on the ground. Leaflets 2-4 inches in length, and
often as broad as long; the terminal one usually subcordate ; the lateral ones
inequilateral, pubescent beneath. Stipules small, lanceolate. Racemes 4 -
12 inches long, slender, loosely flowered: pedicels 2-4 lines long, with 3 minute
hairy bracts at the base. Calyx somewhat bilabiate; teeth broad and very
short, the upper ones rounded. Corolla purple. Legume 14-24 inches long
and 4-5 lines wide, somewhat tumid, strongly falcate. Seeds oblong-reni-
form, dark purple.—Elliott considered the Northern plant as distinct from the
Southern one ; but we find no constant difference between them.
2. P. sinuatus (Nutt! mss.): perennial, nearly glabrous, prostrate; leaflets
reticulated, 2-3-lobed; the lobes obtuse; peduncles longer than the
leaves, mostly solitary, simple; legumes pendulous.
East Florida, Mr. Ware! (Nuttall) Tampa Bay, Dr. Burrows!—
Stem 4-6 feet long. Leaflets 1-14 inch long, somewhat coriaceous, sometimes
obtusely triangular, but usually almost equally 3-lobed. Stipules small,
lanceolate. Racemes 6-8 inches long; the flowers rather distant and chiel-
ly produced on the upper portion of the peduncle. Flowers and legume as
in the preceding species, from which it is at once distinguished by its lobed
and much smaller leaves; but it is possibly a mere variety of that plant.
§ 2. Stipules adnate to the petiole, produced and fre e at the base: lower
tooth o f the calyx as long or longer than the tube: legume linear,
straight, somewhat terete.—S trophostyles, Elliott.
3. P. diversifolius (Pers.): annual; stem usually prostrate; diffuse, re-
trorsely and roughly hirsute; leaflets broadly ovate, angular or 2-3-lobed,
sometimes entire, about the length of the petioles; stipules lanceolate; peduncles
longer than the leaves; flowers few, capitate; lower tooth of the
calyx narrow, longer than the tube; legume slightly pubescent, broadly linear,
nearly terete, 6-7-seeded ; seeds oblong-cylindrical, woolly.—Pers. syn.
