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.
