1. L . bicolor; annuus, caule ramoso procumbente folioso foliisque pilosis vix sericeis,

latis, labio superiore bifido, inferiore elongato integro, alis vexillo longioribus, leguminibus

Hab. Common under the shade of solitary Pine trees, near the ocean, on the North-West coast of
America, and thence as far east as the Tallies of the Rocky Mountains. Douglas.—A humble, procumbent,
branching annual, with small purple or blue and white flowers. Specimens of it are in my Herbarium,
gathered by Mr. Menzies in California. /
2. L . micranthus; annuus, floribus subverticillatis sessihbus bracteolatis, calycis labio
superiore bifido, inferiore integro, foliolis 5—7 lineari-spathulatis ciliatis, leguminibus 6-
spermis transversim sulcatis, caule ramoso, radicibus granulatis.—Douglas in Bot. Reg. t.
1251.
Hab. On the gravelly banks of the southern tributaries of the Columbia, and barren ground in the
interior of California.—Of this I possess no specimen, and Mr. Douglas himself observes, “ that it has much
affinity with the L. bicolor, differing in flowering from four to six weeks earlier, in being more slender, in
the shortness of its ake, its nearly sessile flowers, fleshy leaves, granulated roots, larger pods, and the colour
and size of the seeds.”
3. L . pusittus; annua, parva, pilosissima, caulibus brevibus basi ramosis, foliolis 5-7-
oblongo-lanceolatis obtusis infeme attenuatis, racemis axillaribus lateralibus terminalibusque
sessilibus, floribus altemis ebracteolatis, bracteis longitudine calycis cujus labio superiore
bifido, inferiore duplo longiore bidentato, legumnubus hispidissimis dispermis, semimbus
orbicularibus planis.— Pursh, FI. Am. v. 2. p. 468. Nutt. Gen. v. 2. p. 93. De Cand. Prodr.
v. 2. p . 408.
Hab. On the barren grounds of the Columbia. Douglas.—This is a very singular species, with short,
sessile, many-flowered racemes. The membrane of the fllaments is very large, five of the stamens are
elongated and barren, five shorter with linear orange-coloured anthers. Legumes about an inch long, each
with two flat seeds. ,
* * Herba perennes.
f Flores carulei, purpurei, rarius albi.
4. L . lepidus; herbaceus, perennis, floribus alternis pedicellatis ebracteolatis, calycis
villosi labio superiore bipartito inferiore acuminato elongato, foliolis 5-7 lanceolatis utrinque
sericeis, caule florido erecto subunifolio. Lindl.—Douglas in Bot. Reg. t. 1149.
Hab. About Fort Vancouver, on the Columbia, and in the vallies of the Blue Mountains, North-West
America. Douglas.—This and the following species have the stem so bare of leaves, that it might almost be
called a scape j whilst in almost all the succeeding species the stem is very leafy.
5. L. minimus; herbaceus, dense sericeo-pilosus, parvus, caule 1-2-foliato, foliolis 7-9
lanceolatis acutis inferne attenuatis, floribus alternis verticillatisque, pedicellis ebracteolatis,
calycis labio superiore apice bifido, inferiore integro, radice parva subfusiformi.—Douglas,
MSS. in Herb. Hort. Soc.
Hab. Mountain-vallies in North-West America, near the Kettle Falls; and very abundant towards the
Rocky Mountains, along the course of the Columbia. Douglas.—This is a small species, scarcely a span high,
and allied to the following, but differing in its very dense and silky foliage, in the stem bearing only one or
two leaves, (but several radical ones,) and in the usually verticillate flowers.
6. L. perennis; herbaceus, floribus alternis pedicellatis bracteolatis, calycis labio superiore
subemarginato infer, integro, foliolis oblongis mucronatis subtus subvillosis, radice
repente. DC.—Linn. Sp. PI. p . 1015. Mich. Am. v. 2. p . 55. Pursh, FI. Am. v. 2. p. 467.

Hab. Canada. JMichaux. Shores of the Arctic Sea. Dr. Richardson. Upper Canada, plentiful. Douglas.
Cape Mulgrave, in Behring’s Straits. Messrs. Lay and Collie, in Captain Beechers Collection.—Dr.
Richardson’s specimens have the leaves more acute, and the plant itself somewhat more hairy than in Dr.
Boott’s specimens from the United States.
7. L . Nootkatensis; herbaceus, caulibus patenti-pilosissimis, floribus subverticillatis pedi-
cellatis ebracteolatis, calycis valde hireuti labio utroque integro, bracteis linearibus calyce
longioribus pilosissimis, foliolis oblongo-lanceolatis obtusis mucronatis infeme attenuatis
subtus sericeis. Donn, Cat. Cant. Pursh, FI. Am. v. 2. p. 458. Sims in Bot. Mag. t. 1311,
and t. 2136.—p. glaber.
Hab. «. North-West America. Menzies, Douglas. Nootka and Unalaschka. (Pursh, De Cand.)—a.
and p. Rocky Mountains, north of the Smoking River, in lat. 55°.—Of the only two specimens in Mr. Drummond
s Collection, one is quite glabrous; the other densely villous and exactly corresponding with the L.
Nootkatensis, cultivated in the Horticultural Society’s Garden, from seeds brought home by Mr. Douglas,
and which I consider to be the true state of the plant. It is well represented in the Bot. Mag. t. 1311,’
except that the raceme being in an advanced state, the bracteas are wanting, which appear to me to form an
essential character in the species; for here they exceed in length the flower-buds, till these are fully expanded.
The var. p. of Bot. Mag. t. 2136, is said to be fruticose and quite hardy.
