He enriched the fame colleftion with various other bota¬ 
nical papers, of which one of the moll important was his 
account of the Sitnarouba bark, and its ufe in the dyfen- 
tery, in the year 1729 and 1731. He published feveral fe- 
parate works, among which are, j. Eloge de M. Fagon, 
avec rHiiloiredu Jardin Royal de Paris, & une Introduc¬ 
tion a la Botanique, 1714. 2. Difcours fur le Progres de 
la Botanique, 1718. 3. De Analogia inter Plantas & Ani- 
jnalia, 1721. He edited the polthumous papers of Barce- 
lier, and reduced the plants obferved by him to the Tour- 
nefortian fyltem ; and likewife reprinted the Inltitutions 
of Tournefort, and added an Introduction, and Life of 
the author. 
JUSSIEU' (Bernard de), brother to the preceding, alfo 
a phyfician and botanift, was born at Lyons in 1699. He 
was made a doCtorof the faculty of Paris in 1728, and ob¬ 
tained the place of botanical demonftrator in the royal gar¬ 
den, and admiilion into the Academy of Sciences. He 
was an excellent botanift, but was prevented by his mo- 
defty from writing much. He gave, in 1725, an improved 
edition of Tournefort’s Hiftoire des Plantes qui naiffent 
aux Environs de Paris, a vols. 12010. and alfo publilhed 
a Catalogue of Trees and Shrubs which may be reared 
about Paris, 1735. He communicated a few botanical pa¬ 
pers to the Academy of Sciences, which are printed in its 
Memoirs. Bernard was confulted by Louis XV. on the 
formation of a botanical garden at Trianon, and had feve¬ 
ral conferences with the monarch, who exprelfed great ef- 
teem for him. But, as his modefty did not permit him to 
afk for any thing, nothing was given hint., not even the reim¬ 
bursement of the expence of his journeys . He vifited England, 
where he was made a fellow of the Royal Society, and 
whence he carried the firft plants of the cedar of Lebanon 
feen in France. This botanift difcovered by his experi¬ 
ments the manner in which the feminal farina of plants is 
made to explode ; and alfo confirmed Peylfonel’s opinion 
that moft corallines, corals, and madrepores, are animal, 
and not vegetable, productions. He publilhed a memoir 
of the efficacy of eau-de-luce againft the bite of a viper. 
He palled his life in the privacy of a man of true fcience, 
univerfally efteemed for his knowledge and virtues; and 
died in 1777. 
JUSSIEU'A,/. [fo named by Linnasus from Antony 
de Juffieu.] Tree-Primrose; in botany, a genus of the 
clafs decandria, order monogynia, natural order of caly- 
canthemae, (onagrae, JuJf.) The generic characters are— 
Calyx: perianth five-cleft, fuperior, fmall; leaflets ovate, 
acute, permanent. Corolla: petals five, roundiffi, fpread-

Ejfential CharaBer. Calyx four or five parted, fuperior ; 
petals four or five. Caplules four or fiye celled, oblong, 
gaping at the corners ; feeds numerous, minute. Gartner 
remarks, that Ludwigia indeed differs fufficiently from 
this genus in the fabric and fituation of the receptacle of 
the feeds, but that the diftinftion between Jufiieua and 
Oenothera is merely factitious and imaginary. 
Species. 1, Juffieua repens, or creeping juffieua: creep¬ 
ing; flowers five-petalled, ten-ftamened ; leaves ovate-ob¬ 
long. Roots Ample, filiform, Ihort. Stem branching, 
«reeping; branches long, fubdivided, divaricating, fiome- 
what fucculent, round, fmooth. Leaves on ffiort petioles, 
fcattered, fmall, blunt, fpreading, entire, very fmooth ;

Native of Jamaica, in moift watery places, flowering in 
the fpring. Browne fays it is frequent in the low lands 
about Piaintain-garden river.

cending, Ample, even. Items; leaves petioled, ovate-ob-
