2.
These few notes are all I can gather for the present from Lindheimer's letters
and labels, but I will induce him to make fuller observations of this
kind as of much interest for botanical geography. — For a few more
notes see Algarobia glandulosa below.

List of plants contained again in Lindheimer's Collection of 1844 and allready
distributed amongst the plants of 1843.
7.b. Cocculus carolinus D.C. fruiting specimens, collected on the Colorado
river in October.
The female plants have apparently more frequently hastately 3-lobed leaves, than
the
male plants.
8. Streptanthus hyacinthoides Hook. Prairies between Brazos & Colorado
rivers, April and May. — Flowers
nodding, siliques erect; our specimens mostly simple, with linear leaves; some
larger
ones
are branching with linear-lanceolate leaves.
11. Polygala leptocaulis Torr & Gr. along rivulets, west of the Brazos, in May.
18. Paronychia drummondii-bottom-woods and sparsely in
the low prairies Torr & Gr. Sandy prairies west of the Brazos, in
patches together
May. — The specimens differ from those in collection of 1843 by being young plants,
with
good leaves, just beginning to flower.
24. Sida lindheimerii Dry prairies west of the Brazos, June to August. Corolla
yellow,
12 to 16 lines in diameter. I have seen forms of Sida elliottii T & Gr. which somewhat
resemble
our plant, as the peduncles are sometimes elongated. though they never reach the
length
of the leaf; the flowers are of the same size, but the leaves are narrower, smooth
above, the carpells only about 9 in number, nearly orbicular and only slightly
bimucronate.
29. Rhynchosia minima DC naked clayey soil between the Brazos &
Colorado. Septmeber.
39. Dalea aurea Nutt Dry prairies west of the Brazos in May & June
40. Petalostemon obovatus Torr & Gr. Perennial. Dry prairies west of San
Felipe in July.
49. Acacia hirta Nutt. ripe legumes.
51 Vachellia farnesia W. & A. Margin of the Brazos-bottom-woods and
sparsely in
the low prairies west ward, undoubtedly indigenous.
55. Oenothera speciosa Nutt Prairies west of san Felipe, in heavy soil; fl in
March & April.
60. Gaura sinuata Nutt. roadsides and naked declivities west of the Brazos,
April & May.
80 Gutierrezia texana Torr & Gr. Dry prairies between the Brazos & Colorado.
Sept. & Octob.
83. Solidago leptocephala Torr & Gr. Wet places in the prairies west of the
Brazos. Sept.
94. Echinacea angustifolia D.C. In clayey prairies west of San Felipe, April &
May.
96 Helianthus cucumerifolius Torr & Gr. Sandy soil west of the Brazos, Aug.
& Septemb.
We have had occasion to observe this and the nearly related H. praecox, No.
97. and
find them very distinct. Besides the characters enumerated before we find the leaves
of H. cucumerifolius always cordate at base and deeply coarsely
serrate, of a deep
green colour; the involucral scales elongated, with subulate tips, at first erect and
not
covering the disc before the opening of the flowers, afterwards at least partly
reflexed;
coroll of disc flowers with a very short tube and long and wide neck, disc especially
after flowering, hemispherical. — The leaves of H. praecox are mostly
abruptly
attenuate into the petiole, more or less, sometimes indistinctly in other specimens
deeper toothed, but never serrate, of a pale, somewhat cinereous hue; involucro
coroll of disc flowers with a long thin tube and short neck; therefore the disc
much smaller than in the other species, and after flowering nearly flat;
Achenia considerably smaller. — It flowered in our nothern climate
together with the its relative from June to October; in its native place
(Galveston island) Mr Lindheimer's found it in flower in April; it is probably
a biennial plant there germinating in the latter part of the summer, and
coming to perfection early in the following spring.

104. Gaillardia amblyodon Gay in light sandy soil west of the Brazos; May to
July.
rays bright red, brownish purple at base.
107. Hymenopappus artemisiae folius DC Sandy soil, principally in open
bushes near
the Millcreek, 16 miles west of San Felipe. In flower from March to September.
— Lowest leaves entire (in shady places and in later specimens) or lyrate, or usually
pinnatifid, with entire or even with incisely toothed lobes.
110. Marshallia caespitosa Nutt Growing sparsely on dry prairies near the
millcreek
April. — Stems 12 to 15 inches high; lowest leaves spathulate, obtuse 3-nerved;
chaff scales of pappus large, broadly ovate acuminate; but otherwise not
differing from the common form as described by Torrey & Gray.
137. Herpestis cuneifolia Pursh Margin of rivulates and ponds, west of San
Felipe, June.
138. Buchnera americana L. β parviflora, Open prairies west of the
Brazos, April to July.
145 Salvia azurea Lam. Prairies west of the Brazos, May.
153 Monarda ? penicillata covers large spots patches of dry prairie
west of
the Brazos. May to August. It appears to take in the inland regions
of Texas the same place as "the somewhat similar M. punctata in the
lower litoral districts; its pungent taste is similar to the latter one, but
not so strong" Lindh. —
161. Utricularia subulata Lin Wet meadows near San Felipe, April & May.
169. Stillingia silvatica {sylvatica} L. Prairies west of the Brazos, May.
174 Euphorbia bicolor
175 Tragia urens L. on the abrupt banks of rivulets near the millcreek.
May to July. "not stinging!" Lindh.
184. Commelina angustifolia Mich Open grounds, cultivated fields. May to
July.
189. Moraea — — in wet prairies sparsely, but rather common between
the Brazos & Colorado; April to August.
198. Phalangium angustum probably only a variety of Ph. exculentum. Dry prairies
west of the Brazos, April.

215. Brasenia peltata Pursh in clear rivulets in the prairies between the
Brazos
& Colorado; July.
216. Draba cuneifolia Nutt Dry grassy places near Catspring, west of the
Brazos,
in March. — We find amongst our specimens some with nearly, and
others with entirely smooth glabrous silicles. This would indicate that
Draba micrantha
Nutt which differs from D. caroliniana Walt chiefly in the pubescence of the
fruit, is only a variety of this latter one
