T. Clausen</p><!-- --><p>Species 3 (3 in the flora).</p><!-- --><p>Sedella is distinctive in its solitary basal seeds, each in an indehiscent utricle. The plants are often red or reddish. In two species, the utricles have sticky glands that may help dispersal; also, they float in water. Despite some reports, every species has a nectary at the base of each pistil, as in most Crassulaceae.</p><!-- --><p>Clausen proposed the name Parvisedum because he thought Sedella Fourreau of 1868 to be an earlier homynym, but U. Eggli (1992) pointed out that Sedella Fourreau was not validly published. However, Á. Löve and D. Löve (1985) have used “Sedella” in the sense of Fourreau.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Stamens 10; flowers 4-10 mm diam., petals widely spreading, erect in fruit; styles 0.3-1.2 mm. |[[Sedella pumila|Sedella pumila]] |-id=key-0-1 |1 |Stamens 5; flowers 2-4 mm diam., petals erect or ascending, sometimes appressed in fruit; styles 0.2-0.4 mm |[[#key-0-2| > 2]] |-id=key-0-2 |2 |Pistils subglabrous; petals 2.5-3.5 mm; calyx bases tapering to pedicels; seeds 1-1.3 mm. |[[Sedella leiocarpa|Sedella leiocarpa]] |-id=key-0-2 |2 |Pistils stipitate-glandular; petals 1.5-2 mm; calyx bases thickened for 1 mm; seeds 0.7-0.9 mm. |[[Sedella pentandra|Sedella pentandra]] |} </div></div><!-- -->{{#Taxon: name=Sedella |author=Reid V.
