BANKSIANÆ.Banksia Roses.

(So called because all the species contained in this section agree in character with R. Banksiæ, a rose named in honor of Lady Banks.)

Stipules nearly free, subulate, or very narrow, usually deciduous. Leaflets usually ternate, shining. Stems climbing. The species of this section are remarkable for their long, graceful, and often climbing, shoots, drooping flowers, and trifoliate, shining leaves. They are particularly distinguished by their deciduous, subulate, or very narrow stipules. Their fruit is very variable.

R. BanksiæR. Br.Lady Banks' or Banksia Rose.—Without prickles, glabrous, smooth. Leaflets 3 to 5, lanceolate, sparingly serrated, approximate. Stipules bristle-like, scarcely attached to the petiole, rather glossy, deciduous. Flowers in umbel-like corymbs, numerous, very double, sweet-scented, nodding. Tube of the calyx a little dilated at the tip. Fruit globose, black. A native of China. A climbing shrub, flowering in June and July.

Description, etc.—This is an exceedingly beautiful and very remarkable kind of rose; the flowers being small, round, and very double, on long peduncles, and resembling in form the flowers of the double French cherry, or that of a small ranunculus, more than those of the generality of roses. The flowers of R. Banksiæ alba  are remarkably fragrant, the scent strongly resembling that of violets.

Thunberg speaks of the Rosa rugosa  as growing in China and Japan, being extensively cultivated in the gardens of those countries, and producing flowers of a pale red or pure white. The original plant is of a deep purple color. Siebold, in his treatise on the flowers of Japan, says that this rose had been already cultivated in China about eleven hundred years, and that the ladies of the Court, under the dynasty of Long, prepared a very choice pot-pourri by mixing its petals with musk and camphor.

More than one hundred distinct species are mentioned by botanists, in addition to those we have enumerated, but none of very marked characters or much known.
