Halimocnemis pilosa. July. Halimocnemis. This genus is characterised by the ripening fruit, the perianth of which developes no wings or other protuberances, whereas the leaves harden and coalesce thus forming a protective cupule in which the fruit is placed. The species are true summer-plants growing on clayey and saline soil. The habit of H. pilosa is illustrated (fig. 77), and related to this we have H. macranthera and H. villosa. These species.
