Descriptive Notes of Species & Varieties.
C. Amalia, Siebold. — A slender-growing variety of the patens group, furnished with ternate leaves, the leaflets of which are ovate and entire.  The large star-shaped flowers, five to six inches across, are borne singly on the peduncles, and are composed of six or occasionally more (seven to nine) oblong-lanceolate sepals, which are narrowish towards the base, and broadest above the middle; the colour is a very light bluish lilac, paler towards the base of the sepals, the stamens being also of a lilac hue.  The plant is of Japanese origin, and was introduced by Dr. Von Siebold; it is figured in the Flore des Serres (x., t. 1051), but with the sepals narrower than in the natural flower.
