3. P. tenuiflora (Pursh !)—The specimen in Mr. Lambert’s herbarium is
a very poor one, and the flowers have nearly all fallen off. It is very possibly
the same wrth P. obtusiloba, although that species is canescently hairy
(when young) and very slightly glandular; while Pursh’s plant is gla-
brous and the glands are conspicuous.
4. P.longifolia should be stricken out: the synonym is already adduced
under Phaca longifolia, p. 346, where it properly belongs.
8. P. flonbunda, and 9. P. obtusiloba.—Notwithstanding the manifest difference
in the calyx between this and the succeeding species, we have speci-
mens so neariy intermediate in this respect, that wë have good reason to
doubt whether P. obtusiloba is more than a variety. The racemes of thé
™ r,ar-ef “ uch,fe^ er-fl°wered, and the leaflets shorter and broader.
1 he fruit of P. flonbunda is oval, pointed, not wrinkled, but covered with
glandular dots. _ The habit of P. obtusiloba is not unlike Baptisia tinetoria ■
and we suspect it may prove to be P. tenuiflora, as remarked above.

of Lewis (in herb Lamb.) is just the P. brachiata, as fig u r e d ^
Hooker; but is m fruit The figure of Pursh is taken from a flowering specimen
of Nuttall s m the same herbarium (although Pursh makes no men-
tion of having seen any specimen besides that of Lewis), which is only a
different state, and scarcely to be distinguished as a variety. *

Falls of the Ohio, Mr. Wm. Jones! (communicated by Dr. Clapp.)
June.—Stems about 2 feet in length, rather stout, branched from the base,*
diffuse or ascending; the young branches, petioles, calyx, &c. a little pubescent
with appressed hairs. Lower petioles about the length of the leaflets
(an inch or more) ; the upper ones very short. Leaflets reticulated, sometimes
retuse, entirely destitute of glands, as is the whole plant. Stipules of
the lower leaves about half the length of the petioles, obttise ; the Uppermost
as long as the petioles, acuminate. Flowers rather large, apparently pale
blue, the _ keel and wings tipped with violet-purple. Fruit not seen__A
very distinct species. The habit of the plant is somewhat like Trifolium
pratense*

from specimens in an advanced state, when the inflated calyx becomes as
long as the withered Corolla. .

roundish-cuneiform, dotted. Stipules small, membranaceous.
Under the name of P. macrostachya two species have been confounded, as
we had suspected. / These Hooker has recently distinguished, and we therefore
substitute the following amended characters.
26. P . macrostachya (DC.): pubescent; stem, petioles, and peduncles
scabrous with elevated glands ; leaves pinnately 3-foliolate; leaflets lanceolate
ovate, thickly dotted on both sides, acuminate, acute at the base; stipules
small, lanceolate; spikes cylindrical, dense, very long, ofi peduncles 4
times the length of the leaves; the raehis, calyx and bracts very villous
with mostly blackish hairs; calyx not glandular, longer tha* the rhombie
acuminate-cuspidate bracts, the lower tooth nearly as long as the corolla.__

Nootka, Lagascaj ex De Candolle ! California, Douglas /—The spikes
are often 4 inches in length, and narrow; the villous pubescence which is
blackish in Douglas’s plant, is Whitish in the specimen of De Candolle, but
there is no other difference.
26 (a). P. strobilina (Hook Arn.): stem, petioles,, stipules, peduncles,*
and bracts hirsute, and scabrous with fuscous stipitale glands; leaves pinnately
3-foliolate; leaflets broadly rhombic-oval, nearly glabrous above,-
dotted with glands, clothed with a soft pubescence beneath; petioles elongated;
stipules large, broadly ovate, cuspidate-acuminate, membranaceous;
spikes oblong, large and thick, on peduncles scarcely longer than the leaves;
bracts broadly ovate, acuminate, glandular, larger than the flowers; calyx
hirsute with mostly blackish hairs; the lower tooth as long as the eorolla, the
others unequal.—Hook. Sf A m .! bot. Beechey, suppl. p. 332, t. 8 0 .’ P.

California! Douglas!—Stem striated, tall. Leaflets 2-3 inches long.
Spikes thick, about 2 inches long; the bracts Conspicuous, and often almost
concealing the large purple flowers. Ovary and style clothed with villous
hairs.—Very different from the original P. macrostachya, which we had not
seen when our account of the genus Was published. The P. macrostachya
of Lindley we have seen in cultivation, but have no specimen. Judging
