RUB 
chona and gardenia. Jussieu, taking a more accurate and 
comprehensive view of the subject, has greatly extended the 
order, while he has, at the same time, better defined it than 
any preceding botanist. This order is the 57th of his series, the 
2d of his 11th class. The order of rubiaceae is thus defined : 
—Calyx of one leaf, superior, simple; its limb divided, 
or occasionally undivided. Corolla regular, mostly tubular, 
with a divided limb. Stamens definite, four or five, seldom 
more, inserted into the tube of the corolla, alternate with 
its segments, and equal to them in number. Germen in¬ 
ferior ; style one, very rarely double; stigma generally 
double. Fruit in some cases of two lobes, or grains, each 
lobe single-seeded, not bursting, but having the appearance 
of a naked seed; in others a simple capsular or pulpy fruit, 
often of two cells, in each of which the seeds are either so¬ 
litary or numerous; in a few instances there is but one cell, 
in some others many ; the fruit, of whatever description, is 
either crowned with the permanent limb of the calyx, or 
marked with a rim, or scar, where the latter had been. The 
corculum is oblong, slender, inclosed in a large, horny, 
lateral albumen. Stem herbaceous, shrubby, or arboreous. 
Leaves in a few instances whorled, in most opposite, their 
footstalks generally connected at the base, through the 
medium of a simple pair of stipulas, or sometimes a fringed 
kind of sheath, embracing the stem or branch. Plants of 
this order are readily known, even without flowers, by 
their leaves or stipulas. The shrubby and arborescent kinds 
are principally natives of tropical climates, where they greatly 
abound. 
RUBIANA, an inland town in the north-west of Italy, in 
Piedmont, province of Susa. Population 2800. 
RU'BICAN, adj. [cubic an, Fr.] Rubicon colour of a

RUBICON, the ancient name of a small river in the north¬ 
east of Italy, which flowed into the Adriatic to the north¬ 
ward of Rimini. In modern times antiquaries have differed 
much as to its identity, some supposing it to be the Piscia- 
tello, others the Marecchia, and by far the greatest number 
the Luso. It formed the boundary between Italy proper and 
Cisalpine Gaul; but it is chiefly remarkable in ancient his¬ 
tory as the limit prescribed by the Roman senate to the 
advancing army of Caesar, when the ambitious designs of 
that commander became strongly suspected. He disregarded 
the prohibition, and advanced to Rome. 
RU'BICUND, adj. [rubicond, Fr. rubicundus, Lat.]

RUB1GALIA, or Robigalia, a feast celebrated by the 
RUB 
Romans, in honour of the god Rubigus, or the goddess 
Rubigo ; to engage those deities to preserve the corn from 
blasting and mildews. 
The Rubigalia were instituted by Numa in the eleventh 
year of his reign; and were held on the seventh of the 
calends of May, which is our twenty-fifth of April; being 
about the time when the blight or mildew, called by the 
Latins rubigo , uses to attack the corn. 
Varro fixes it to the time when the sun enters the 16th 
degree of Taurus. Indeed the true time seems rather to have 
been on the 18th day before the equinox, and the true rea¬ 
son, because then Canicula, or the Little Dog, sets; which 
is esteemed a malific constellation. 
Hence they sacrificed a dog to Rubigo: Ovid says, the 
entrails of a dog, and those of a sheep; Columella, only a 
sucking puppy. Festus insinuates, that the victim must also 
be red. 
RUBIN, or Roboan, a small island of the Red sea, at

the Red sea.
