The Essex Records 1820 -2007.

Following the introductory paragraph to each taxon, the records are set out in columns. The first being the letter and alternative number (in brackets) code for the 100 x 100km square, followed by the 10 x 10km square number, arranged in conventional order from south to north, moving from west to east; the second column gives the 1 x 1km square or the 100 x 100m square Ordnance Survey grid reference if known; the third the vice county, and the final column the available details of the individual record. Approximate grid references for older records are suffixed by a?

 

Chara globularis Thuill. ( C. fragilis)

This taxon is quite common and widely distributed in Essex ponds, and can withstand quite high levels of nutrient enrichment. The form most frequently encountered having small oval spine cells but no projecting spines, and usually two circlets of tiny globular stipulodes. It is usually a neat, C. vulgaris-sized plant that can be very attractive when festooned with green oogonia and orange antheridia. It is separated from C. virgata rather empirically, on whether or not its primary and secondary cortical rows are equally developed, the latter variety having more prominant primary rows. Other characters are variable, but globularis usually has internodes longer than the branchlets, whereas virgata has them more or less equal, and is a smaller, more delicate plant of waters with a low nutrient status.
