In /. natans^ a succulent species from the marshes of central Asia, dis- tinguished under the generic name of Hydrocera^ the fruit is more or less fleshy and indehiscent; and in that way this species is to the Balsams what Chymocarpus is to the Nasturtiums proper (page 16). Thus constituted this genus contains about a hundred and thirty species,* mostly natives of the warmest regions of the Old World; we meet, however, with a couple in North America and two or three in Northern Europe and Asia. They are herbs, sometimes suflBnitescent, glabrous or covered with hairs, with alternate or oppo- site leaves, exstipulate, with a petiole often glandular at the base. The flowers are solitary or in cymes in the axil of the leaves or of the bracts which sometimes replace them at the summits of the branches. They are accompanied by two lateral bractlets, and their weight often draws them to the summit of the bent down peduncle, while their spur at first posterior may become anterior or Fig. 49.
