IPOMŒA.—The Ipomœas are nearly allied to the Convolvuli, and are among the most lovely of all shrubs. The rosy-red Kâmalatâ, the Love’s Creeper of the Hindus, is a plant by which all desires are granted to such as inherit the Indian Paradise. Ipomœa Bona-nox, “Good-night,” is so named in allusion to its opening its flowers in the evening.

IRIS.—The Iris of “all hues” derives its name from the goddess Iris, one of the Oceanides, a messenger of the gods, and the especial attendant of Juno. As goddess of the rainbow, she is represented with its variegated colours glistening in her wings. Thus Virgil says:—

“Iris on saffron wings arrayed with dew

Of various colours through the sunbeams flew.”

Iris is usually depicted as descending from the rainbow, and her glorious arch is said not to vary more in its colours than the flower which bears her name. Columella observes—

“Nor Iris with her glorious rainbow clothed

So fulgent as the cheerful gardens shine

With their bright offspring, when they’re in their bloom.”

The Greeks plant the Iris on tombs, possibly because the goddess Iris was believed to guide the souls of dead women to their last resting-place, as Mercury conducted the souls of men. The Iris was one of the flowers dedicated to Juno, and with the ancients was wont to be employed as the symbol of eloquence or power; hence the Egyptians placed this flower on the brow of the Sphinx, and on the sceptres of their monarchs. The three leaves of the blossom represent faith, wisdom, and valour. The Iris is supposed to be the flower which forms the terminating ornament of the sceptre of the ancient kings of Babylon and Assyria.——The Franks of old had a custom, at the proclamation of a king, to elevate him upon a shield, or target, and place in his hand a reed of Flag in blossom, instead of a sceptre, and from thence the kings of the first and second race in France are represented with sceptres in their hands like the Flag with its flower, and which flowers became the armorial figures of France.——There is a legend that Clotilda, the wife of the warlike king Clovis, had long prayed for the conversion of her husband, and at length Clovis, having led his army against the Huns, and being in imminent danger of defeat, recommended himself to the God of his sainted wife. The tide of battle turned, he obtained a complete victory, and was baptised by St. Remi. On this occasion, owing to a vision of St. Clotilda, the Lilies (Iris) were substituted in the arms of France for the three frogs or toads which Clovis had hitherto borne on his shield. In the pictures of St. Clotilda, she is generally represented attended by an angel holding a shield on which are the three Fleurs de Lys. This occurred early in the sixth century. Louis VII., in consequence of a dream, assumed it as his device in 1137, when engaged in the second expedition of the Crusaders, and the Iris-flower soon became celebrated in France as the Fleur de Louis, which was first contracted into Fleur de Luce, and afterwards into Fleur de Lys, or Fleur de Lis (Lily-flower—although it has no affinity to the Lily), and was incorporated in the arms of France, and formed one of the embellishments of the crown.——Pope Leo III. presented Charlemagne with a blue banner, semée of golden Fleurs de Lys, and the banner coming from the Pope was supposed by the ignorant to have descended from heaven.——Other traditions respecting this blue banner relate that an angel gave it to Charlemagne, that St. Denis gave it to the kings of France, and that an angel brought it to Clovis after his baptism.——The Fleur de Lys appertains to the Bourbon race, and was made the ornament of the northern radius of the compass in honour of Charles of Anjou, who was King of Sicily at the time of this great discovery. When Edward III. claimed the crown of France in 1340, he quartered the ancient shield of France with the lion of England. After many changes of position, the Fleur de Lys finally disappeared from the English shield in the first year of the present century. (See also [Flower de Luce]).
