Salvia scapiformis is an herb that is native to several provinces in China, along with Taiwan and the Philippines, growing at 100 to 1,200 m (330 to 3,940 ft) elevation. S. scapiformis grows on slender stems to 20 to 26 cm (7.9 to 10.2 in) tall, with mostly simple leaves that are basal or subbasal, rarely growing on the stem. Inflorescences are widely spaced 6-10 flowered verticillasters in terminal racemes or panicles that are 10 to 20 cm (3.9 to 7.9 in) long. The corolla is purple or white, approximately 7 mm (0.28 in).

A raceme is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers along its axis. In botany, an axis means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard and radish plants.

Panicle type of inflorescence

A panicle is a much-branched inflorescence. Some authors distinguish it from a compound spike, by requiring that the flowers be pedicellate. The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth.

There are three named varieties, with slight variations in leaves, verticillasters, and calyx:
