''E. pallida'' is similar to ''E. angustifolia'', but plants often grow taller, ranging from 1.5 to 2.5 ft (45 to 75 cm) tall, with some growing 3 feet (90 cm) or more tall. Plants normally grow with one unbranched stem in the wild, but often produce multi-stemmed clumps in gardens. They have deep taproots that are spindle shaped, wider in the center and narrowing at the ends. Stems are green in color or mottled with purple and green. The leaves are elongated lanceolate or linear-lanceolate in shape with three veins. Flower head rays are narrow, linear, elongated, and drooping, ranging from 1 to 3 inches (2.5 to 7.6 cm) long. The flower heads are from ¾ to 3 inches (2 to 7.6 cm) wide with pale rose-purple or nearly white colored petals. The flowers have white pollen. The fruits are cypselae and are tan or bi-colored with angled edges.

It is native to the United States where it is found growing in dry soils, in rocky prairies, open wooded hillsides, and glades. It grows natively as far north as Michigan and southward in to Alabama and Texas, and has been introduced outside of its native range into Connecticut, Georgia, Maine, Massachusetts, Minnesota, New York, North Carolina, and Virginia. E. pallida blooms from May into July. The states of Tennessee and Wisconsin list the species as threatened, mostly due to habitat loss and over-collection of roots.

A sensitive TLC method to identify Echinaceae pallidae radix.

Abstract. In this work a fast, simple and sensitive qualitative TLC method was developed to identify Echinaceae pallidae radix and to distinguish this drug from similar ones. The TLC method is based on the lipophilic compounds of E. pallida. Three mobile phases provided good separation, e.g. toluene/ethylacetate 7 + 3 (v/v). A marker substance was found which shows a blue fluorescence at an excitation wavelength of 366 nm after detection with a spray agent containing 95 volume parts ethanol 96%, 5 parts trifluoroacetic acid 99% and zinc ions in 0.15 molar concentration. After spraying the chromatogram was heated at 110 degrees C for 7 min. This method is superior to HPLC methods to characterise mixtures of Echinacea extracts in terms of selectivity due to this post-chromatographic derivatisation and subsequent fluorescence detection.[4]
