Schizomeris<br />
Classification: Chlorophyta (Family<br />
Schizomeridaceae)<br />
General habit: pl<strong>an</strong>ts uniseriate in lowers regions<br />
but becoming multiseriate above, yellow-green to<br />
grass-green in color, loosely attached to rock<br />
surfaces in streams<br />
Species in Hawai‘i: S. leibleinii<br />
Isl<strong>an</strong>d distribution: O‘ahu, Maui<br />
Distinguishing features: main axis composed <strong>of</strong><br />
only a single filament in the lower areas, but<br />
becoming multiseriate (composed <strong>of</strong> several<br />
filaments) in the upper regions, brick-like cells,<br />
chloroplast plate-like <strong>an</strong>d <strong>of</strong>ten encircling <strong>an</strong>d filling<br />
the cells, especially in mature regions<br />
Compare with: not likely to be confused with other<br />
