The calyx is a cone of fleshy, rounded sepals, and there are no petals. The fruit is an utricle that grows within the calyx. This rare plant, "Suaeda californica", grows in a restricted area within the intertidal zone of salt marshes. It is threatened by anything that alters the hydrology of the area, such as changes in sedimentation, including dredging, erosion, and recreation. It requires a porous substrate high in nitrogen, which may come from decaying plant matter and
MPEG Surround also successfully demonstrated. MPEG Surround's backward compatibility and relatively low overhead provides one way to add multichannel sound to DAB without severely reducing audio quality or impacting other services. Currently, the majority of digital TV broadcasts use stereo audio coding. MPEG Surround could be used to extend these established services to surround sound, as with DAB. Currently, a number of commercial music download services are available and working with considerable commercial success. Such services could be seamlessly extended to provide multichannel presentations while remaining compatible with stereo players: on computers with 5.1 channel playback systems the compressed sound files are
