Primula. Primula sp.
Primula.—The leaves of the various species of this genus produce irritation when handled, due to a secretion in the glandular hairs. For a study of primula dermatitis, see Forster, J. A. M. A., 1910, lv, p. 642. From the roots of Primula grandiflora, Bongault and Alland have separated a crystalline polyatomic alcohol, primulite, which is said to be identical with the hepatomic alcohol, volemite. (C. R. A. S., 135, 796.) Two glucosides, primverin and primulaverin, and an enzyme, primverase, were isolated by Goris and Mascne. (Chem. Cb., 1910, No. 3.)
