the venillum. Stamens diadelphous. Sti)* of ovary sheathed by a 
little tube. Stigma emarginate. Legume many-seeded, and two- 
celled ; the seeds intercepted by dissepiments. (G. Don.) 
Description, &c. — The name of Apios is taken from Apion, a pear, in reference to the shape of the tuberous 
roots. There is only one species in the genus, which was formerly included in the genus Glycine. 
Generic Character. — Calyx campanulatc, with four almost obso- 
lete teeth, and one acute, elongated, one under the keel. Corolla 
papilionaceous, with a falcate linear carina, bent back upon the top of

Specific Character. — Roots tuberous. Leaves imparl -pinnate. 
Flowers in axillary racemes. Bratioles closely adpressed to the calyjf, 
but soon falling off. 
Description, &c. — This very elegant climber is a native of Virginia, and though frequently killed down to 
the root by the severity of British winters, it will shoot up again in spring, and grow to the height of ten feet or 
more before it flowers, which is generally in August or September. It is propagated by its tuberous roots, 
which are sweet and eatable, resembling those of the Jerusalem Artichoke, but they are more floury. The plant 
is cultivated in Germany for its tubers, which are sold in the markets. The species was introduced before 1640 ; 
but it is now rarely met with. 
GENUS XVIII. 
LUPINUS, Lin, THE LUPINE. 
Lin.Syst. MONADELPHIA DECANDRIA. 
Generic Character. — Calyx profoundly bilabiate. Corolla papilio- 
naceous, the vexillum with reflexod sides, and the keel acuminated. 
Stamens monadelphous, with the tube or sheath entire, five of the 
anllicrs are smaller, rounder, and earlier, and the other five, oblong, and 
later. Style filiform. Stigma terminal, roundish, bearded. Legume 
coriaceous, oblong, compressed, obliquely torulose. Cotyledons thick, 
but converted into leaves at the time of germination. Herbs or sub- 
shrubs with digitate leaves, constantly composed of from 5 — 1 5 leaflets, 
very rarely simple. Leaflets complicated before expansion, and while 
asleep, or through the night. Stipules adnate to the petioles. Peduncles 
opposite the leaves or terminal. Flowers alternate or verticillate, sessile 
or pedicellate, disposed in racemes and spikes, with one bractea under 
each pedicel, and with two braeteoles adhering laterally to the calyx, 
which are caducous, or wanting. (G, Don.) 
Description, &c. — The name of Lupine is derived from the word lupes, a wolf, because a crop of lupines was 
formerly supposed to destroy the fertility of the soil. But this opinion is singularly at variance with the practice 
of the modern Italians, who sow a crop of white lupines as a preparative for Corn. It is true that the Italians 
do not suffer their lupines to seed, but dig the green crop into the ground as soon as it is beginning to form
