FIGURE 6. Comparison of herbarium specimens of Drosera margaritacea (left) and D. finlaysoniana (two plants on the right). Note the differences in inflorescence size, peduncle length and numbers of flowers per inflorescence. These features allow quick identification of herbarium material without microscopic indumentum inspections. Inset shows macro-photograph of stalked-milky white glands on petiole of D. margaritacea. Note that these glands retain their shape in dried material but lose stickiness (as tested with steel needle visible on right edge of this inset). Left specimen T. Krueger 7 (holotype; PERTH), right specimens T. Krueger 6 (PERTH, MIN). Photographs by T. Krueger.
