If Mauriciae figures are taken as a basis for comparison the following forms
stand out. all the specimens examined here from wood, had Gemmiparous
stems, which however varied in abundance from plenty to very few, so few that
considerable examination was necessary to find them
While always the involucral bracts were serrated irregular serrate the figure
by Mauricia shows the entire form from these they varied to forms with fewer
or smaller teeth often both, but no bracts were found that were quite entire.
Mauriciae figures the leaves as equally bilobed plicateate, acute to acuminate
that seemed constant on well formed stems, but it was not unusual to come
across deformed specimens where the leaves were very small, as small as or smaller
than a small Cephalodella & in such cases there was also a very considerable
amount of variation in shape, nearly a few lobes would be struck, but the sinus could
be acute to obtuse, with almost parallel to wide apart tips.
Mauricia gave the cells as 16-24, I find them averaging 17 at a mean even
giving larger new base where from 20-25. irregular in size & arrangement, &
always much undulated, but not so strongly. while occasionally gemmiparous shoots were
as figured by Mauricia, it was frequently the case that they were with stem the stem,
& below made like the leaves on ordinary stem. This fig & of stem does not show the
summer form. This occasionally met with, they seem more like the lower leaves
shown in figure stem. The perianth, bilobate & bifid, usually had the teeth
extended into tubes up to 8 cells long, but there was considerable variation of this
character, some showing fewer & shorter ridges, but ridges seemed always present, &
they seemed to be somewhat flattened & incurved above. The gonidia are quite frequently
rather distinct from stem of fronds of Mauricia, but attract attention mostly by their
bright red colour.
