Alkali Bulrush

Image of Sea Club-Rush

Description:

Known also as Salt marsh bulrush, Seacoast bulrush, Cosmopolitan bulrush, Bayonet grass (although it is not a grass species), and others.Plants here were mostly around three to four feet tall (although they can be somewhat taller, up to 1.5 m) and were growing in a small but fairly dense cluster, which is typical for this perennial, rhizotamous native species. Spikelets are mainly sessile. Styles of the western hemisphere subspecies are bifid (also referred to as 2-fid) which is difficult to see here but I was able to confirm that at higher magnification. Stems are triangular (i.e. triquetrous) and the involucral bracts greatly exceed the inflorescence.The species has a worldwide distribution with two different subspecies currently recognized. The taxonomy of this species is somewhat complex. The subspecies in the western hemisphere with the 2-fid styles is Bolboschoenus maritimus subsp. paludosus (syn. Bolboschoenus maritimus var. paludosus, Scirpus maritimus var. paludosus).A synonym for the species would also include Schoenoplectus maritimus but that name would not apply to the western hemisphere form since it was never combined with the subspecies epithet. And, other "Scirpus" species which are now in Schoenoplectus including S. acutus and S. americanus and S. pungens remain there. But not Alkali bulrush which has been moved into own separate genus, i.e. BolboschoenusJune 29, 2014, elev. approx. 4,340 ft., Salt Lake County regional park complex, growing with Typha latifolia, Eleocharis palustris, Fremont's cottonwood hybrids, and the very invasive Solanum dulcamara. Less than 50 plants, wet meadow habitat opened up by Russian Olive removal, but with many highly undesirable Russian Olive trees remaining which are slated for further removal activities.
