Calceolaria Alba - One of the most attractive, with narrow dark green leaves, slightly toothed.
Calceolaria Amplexicaulis - A fine kind with soft green leaves clasping the stem and many lemon-yellow flowers.
Calceolaria Hyssopifolia - One of the best of the dwarf kinds, bearing loose clusters of lemon-yellow blossoms from early summer till autumn, the foliage resembling that of Hyssop.
Calceolaria John Innes - A remarkably fine plant raised at the John Innes Horticultural Institute, Surrey, the result of crossing C. plantaginea and C. polyrrhiza.
Calceolaria Kellyana - A curious hardy hybrid, with short downy stems, 6 to 9 inches high, flowers about an inch across, yellow with numerous small brown dots top of the stems.
Calceolaria Pavonii - A noble kind, from 2 to 4 feet high, with large light green, much-wrinkled foliage, bearing large, pale yellow, slipper-shaped blossoms.
Calceolaria Plantaginea - A low-growing plant spreading by means of short side growths; the leaves, formed in rosettes, are broadly ovate, with toothed margins and attain a considerable size in moist positions.
Calceolaria Polyrrhiza - creases rapidly by means of wide-spreading rhizomes, and quickly finds its way into conditions which suit it.
Calceolaria Violacea - A distinct kind, with small helmet-shaped flowers, rich purple and spotted; succeeds well on warm borders or the rock garden, and, if slightly protected, withstands mild winters in the south.
Especially noteworthy are the Andine Acaena, Gunnera, Fuchsia and Calceolaria.
In some corollas the two lips become hollowed out in a remarkable manner, as in calceolaria, assuming a slipper-like appearance, similar to what occurs in the labellum of some orchids, as Cypripedium.
They are hooded and pouched like a Calceolaria flower, and about an inch across every way.
