138 THE LADIES' FLOWER-GARDEN 
GENUS III. 
THERMOPSIS, B. Br. THE THERMOPSIS. 
Lin. Syst. DECANDRIA MONOGYNIA. 
many-seeded. Perennial herbs, clothed with sillty villi. Leaves tri- 
foliate. Stipules ovate-lanceolate, leafy. Racemes terminal. Flowers 
pedicellate, twin, or somewhat verticillate, yellow. (Cr. Don.) 
Generic Character. — Calyx oblong or campanulate, 4 — 5-toothed, 
somewhat bilabiate, convex behind, and attenuated at the base. Petals 
five, about equal in length. Vexillum with reflexcd sides. Keel 
obtuse. Stamens permanent. Legume compressed, falcate or linear. 
Description, &c. — The species belonging to this genus appear to have given a great deal of trouble to botanists, 
as they have been removed two or three times to different genera. They are all handsome plants, vwth large yellow 
pea-flowers, closely resembling those of the different kinds of Cytisus, or Lupine. The name of Thermopsis, 
indeed, indicates this latter resemblance, as it is from two Greek words, signifying like a Lupine. 
1.— THERMOPSIS RHOMBIPOLLA, Nutt. THE RHOMBOID-LEAVED THERMOPSIS. 
shorter than the petiole ; lower flowers of the raceme twin, on very 
short pedicels. 
Synonvme. — Cytisus rhombifolius, Fraser. 
Specific Character. — Leaves stalked ; leaflets rhomb-ovate, some- 
what cuneated, rather silky-pubescent ; stipules obliquely ovate, acute. 
Description, &c. — The flowers are yellow, and closely resemble those of a Cytisus. The plant is a native 
of Louisiana, and it was introduced in 1811. 
2.— THERMOPSIS FABACEA, Dee. THE BEAN-LIKE THERMOPSIS. 
Synonymes. — T. rhombifolia, Rich.; Sophora fabacea, Pall, f Specific Character. — Leaves stalked ; leaflets broad-oval ; stipules 
S. lupinoides, var. Lin. ; Thermia rhombifolia, Nutt, ; Cytisus broad-ovate, obtuse, shorter than the petioles ; racemes with alternate 
rhombifolius, Pursh. flowers. (G. Don.) 
Enoraving.— Bot. Mag. t. 3611. 
Description, &c. — This species is found on the whole of the western side of North America, from north to 
south ; but nowhere on the east. It is also found in Kamtschatka. It is quite hardy, and it is readily increased 
by dividing its creeping root. It grows best in sandy soil. It was first introduced in 1824 ; but afterwards 
again in 1837. 
3.— THERMOPSIS LANCEOLATA, R.Br. THE LANCEOLATE-LEAVED THERMOPSIS. 
simple, like stipules, the rest trifoliate ; leaflets oblong- lanceolate ; 
stipules twice the length of the petioles, or more, flowers twin ou the 
racemes ; pedicels shorter than the calyx. {G. Don.) 
Synonymes. — Sophora lupinoides. Pall. ; Podalyria lupinoides, 
Willd. 
Engraving.— Bot. Mag. t. 1389. 
Specific Character. — Leaves nearly sessile, lower and upper ones 
Description, &c. — This species bears considerable resemblance to the last in its flowers, though its leaves 
are smaller. It is a native of Siberia, whence it was introduced so long back as 1775, though it is rarely to be 
met with in gardens. It is quite hardy, but it is very liable to be eaten by slugs. 
4.— THERMOPSIS CORGONENSIS, Dec. THE ALPINE THERMOPSIS. 
Synonymes. Sophora alpina, Pail. ; Podalyria alpina, Willd. a kind of half whorl ; flowers twin on the racemes, nearly sessile ; 
Specific Character. — Leaves sessile, or on very short stalks ; leaf- calyx villous. {G. Don.) 
lets ovate, acute ; stipules like the leaves, and with them constituting 
Description, &c. — This species is much smaller than the others. It is a native of the Altaian Mountains, 
whence it was introduced in 1824. It is quite hardy.
