JEFFERSONIA, Bar. THE JEFFERSONIA. 
Lin. Syst. OCTANDRIA MONOGYNIA. 
Generic Chab4cteii. — Calyx of four sepals. Petals ciglit. Stamens | cumference of the apex. Seeds numerous, furnished at the base with 
eight, with short filaments. Capsules opening by the whole cir- I a lacerated arillus. (G. Don.) 
Description, &c. — There is only one species which was formerly considered to belong to Podophyllum, 
but which was separated from that genus on account of the natural opening of the capsule. The new genus 
was found by Dr. Barton, and named by him in honour of Jefferson, the president of the United States.

Specific Character. — Leaves profoundly cleft into two lobes. 
Peduncles 1-flowered. Flower white ; anthers yellow. Calyx 
deciduous, coloured. Seeds shining. (C Don.) 
Description, &c. — A very pretty little plant, which flowers when not more than three or four inches 
high ; though, after the flowers fall, the stem and leaves grow to the height of a foot or more. It is a 
native of Tennessee and Virginia in North America ; always growing in moist places. In gardens it succeeds best 
in peat soil, mixed with sand and a little loam ; and it should always be kept in a shady situation. It is 
generally increased by dividing, the root ; and it is sometimes killed by severe frosts. The seed-vessel, after 
the petals have fallen, bears considerable resemblance to that of the poppy. The species was introduced in 1792.

way above the petals. 
Lin. Syst. POLYANDRIA P0LY6YNIA. 
Oeneric Character. — Calyx of four sepals, girding the base of the 
tonis. Petals sixteen to twenty-eight, adnate to tlie torus, elevated 
about the ovary and covering it, so as to appear at first sight inserted in 
Descbiption, &c. — The Water Lilies are all showy aquatic plants, with fleshy stem-like main roots, fringed 
with numerous fibres. The leaves are very large and flat ; and floating, with the stem in the middle. The flowers 
are very large, and generally white, but sometimes rose-coloured or blue, but never yellow ; and they are 
generally so placed as to seem to repose on the surface of the waters. The common white Water Lily (A^ alba) 
is perhaps the most beautiful species.
