Petals usually deciduous stamens usually many buds not scaly. 

Scaly buds are such as have their outer leaf rudiments transformed into scales there are often coated with a waxy or resinous substance without and a downy lining within, to protect them from sudden changes in climate. Buds of this character are common among shrubs and trees of temperate regions. 

Undergroimd Stems.—A rhizome is a creeping underground stem, more or less scaly, sending off roots from its lower surface and stems from its upper. The rhizome grows horizontally, vertically or obliquely, bearing a terminal bud at its tip. Its upper surface is marked with the scars of the bases of aerial stems of previous years. Examples Triticum, Rhubarb, etc. 

Scale Leaves.—Scale leaves are reduced foliage leaves. They are found on certain rhizomes, above ground stems, such as Dodder, etc., on bulbs, and forming the protective scales of scaly buds. 

Free lateral stipules are seen in Leguminosce, Rosaceoe, Beeches, etc. They are free on either side of the petiole and supplied by vascular tissue from the petiolar bundle mass. In appearance and duration they may be either green, foliaceous and persistent or membranous to leathery, scale-like and caducous. Caducous scaly stipules only function as bud scales through the winter and fall in spring as the buds expand.

Traditional Medicine. Root, leaves, and seeds (fruits) of both species have been used in treating cancers decoctions or tea of the root have been used in treating rheumatism, catarrh, gout, and stomach ailments. The root is used as a diuretic, diaphoretic, and mild laxative, among other uses. Decoctions and teas of roots and leaves have been used both externally and internally for skin problems (e.g., eczema and scaly skin) (foster and duke lust tyler 1). The Micmac Indians used the roots and buds to treat sores, and a tea made from the seeds or roots was used by the Cherokee as a blood cleanser (moerman).
