CHARACEAE. 215 
CHARACEAE.* 
Chara fragilis, Desv. 
Native. First record: Marquand, 1891. 
Plentiful in deep pools at Grande Mare. Also in the pool close 
to Fort Doyle. Var. barbata, Gant. Grande Mare. ‘A form 
with prominent primary cortical cells, and unusually well-developed 
spine-cells.’ (Groves.) Var. capillacea. Coss. & G. In a quarry 
pool at the eastern side of Lancresse Common. 
Chara aspera, Willd. 
Native. First record: Marquand, 1891. 
In pools at Grande Mare. Var. subinermis, Kuetz. Grande 
Mare. 
Chara baltica, Bruz. Var. affinis, H. & J. Groves. 
Native. First record: Marquand, 1891. 
Plentiful in one of the shallow pools at the south side of Grande 
Mare. If the draining of the marsh is proceeded with, this rare 
British Chara, like several other interesting plants, will soon be 
extinct in this island. 
Chara vulgaris, L. 
Native. First record: Babington, 1839. 
The most frequent species in Guernsey. Pool by Fort Doyle. 
Plentiful in an old quarry pool at Portinfer. I have also found it at 
Herm. No locality is specified for this species in FZ. Sarn. Var. 
longibracteata, Kuetz. Sparingly in 1892 in a small roadside 
pool at Cobo. Var. papillata, Wallr. Roadside pool on the 
eastern side of Lancresse. 
Nitella translucens, Ag. 
Native. First record: Marquand, 1891. 
Very rare. Ditches behind Ivy Castle in 1890 and 1891: in 
small quantity, but extremely fine and fruiting abundantly. 
(The only species belonging to this order mentioned in Gosselin’s 
old list is Chara hispida, Prickly Chara. In 77%. Sarn. Babington 
records two species: C. vulgaris, L., and C. hispida, L., both as 
seen by him. It is impossible to say now whether the true 
C. hispida existed in this island in former times, but it is almost 
certain that it is not to be found at the present day; and therefore 
the doubt arises whether some other species was mistaken for it by 
the old botanists. ) 
* I am indebted to Messrs. H. and J. Groves for kindly examining and determining 
all my gatherings of Guernsey Characeae.
