|discussion=<p>The typical form of <i>Crassula aquatica</i>, with very short fruiting pedicels, grows chiefly in coastal salt marsh. It is rare and widely scattered in Alaska and Canada (W. J. Cody 1954), scarcely more common southward. M. Bywater and G. E. Wickens (1984) separated C. saginoides by pedicels elongate in fruit, sometimes to ca. 2 cm. It grows mostly inland and sometimes to 3000 meters, but from the specimens that they annotated, the ranges are not distinct. N. L. Britton and J. N. Rose (1905) and W. L. Jepson (1923–1925) have separated it, at least varietally, under other names, but most authors have included it without comment or at most have called it doubtfully distinct. I call it merely a phase of <i>C. aquatica</i> not needing a formal name (R. V. Moran 1992b). A typical strand plant is depicted in the lower left corner of the illustration panel on this page.</p>
