Branched, erect, aromatic subshrub; stems woody and smooth. Leaves pinnately to bipinnately divided into linear segments; lamina narrowly ovate in outline; sparsely sericeous with pyriform-headed glandular hairs in between; petiole shorter than lamina. Inflorescences of 2-4-flowered pseudo-umbels; pedicels shorter than hypanthium. Sepals 5, imbricate, connate at base, apex sometimes reflexed. Petals 4, white, pronouncedly unguiculate; posterior 2 auriculate, claws inrolled forming false tubes, with wine-red markings at base, twice as long as anterior petals. Stamens 7, fertile.
