8 MONANDRIA— MONOGYNIA. Chara. 



4. C. translucens. Great Transparent Chara.

 simple, cylindrical, obtuse, with a small point, and trans- 

 verse internal partitions ; fertile ones axillary, compound, 

 partly forked. Bracteas none.

C. translucens major flexilis. Vaill. Mem. de I'Ac. des Sc. for 

 1719.\S.t.3.f.8. 



In pools, rare. 



Near Shrewsbury. Rev. E. Williams. At Browston, Suffolk. Pro- 

 fessor Hooker. Found by Mr. Arnott, and Mr. D, Don^ in 

 various parts of Scotland. Hook. Scot, 



Annual. June, July. 



This is our largest species. Root creeping, of many branching 

 slender fibres, with small knots. Whorled branches near two 

 inches long, barren, all simple, spreading widely, furnished here 

 and there with transverse, often oblique, internal partitions : 

 fertile ones axillary, compound, tumid, ultimately forked, with a 

 dotted anther, and one gcrmen, occasionally two^ at the division, 

 without any proper bracteas. 



5. C. nidifica. Proliferous Chara. 



Smooth, transparent, without prickles. Whorled branches 

 simple, elongated, without internal partitions ; fertile ones 

 axillary, compound. Bracteas unequal. 



C. nidifica. Fl. Dan. t. 76\. Engl. Bot. v. 24. t. 1703. Comp. 2. 



In salt-water ditches. 



At Shoreham harbour, Sussex, and near Cley, Norfolk. Mr. Borrer. 



Annual. August — October. 



Firmer, and rather stouter, than CJlexilis, but much more slender 

 than the last, and more divaricated tlian either. The axillary 

 branches, which bear fructification, and rather numerously sur- 

 round the main stem, within the long slender whorled branches, 

 being themselves whorled and subdivided, cause the bushy or 

 proliferous aspect, which at first sight marks this species. Three 

 or four small, unequal, cylindrical bracteas accompany each 

 flower, as in C. vulgaris and liispida. The anther is often stalked^ 

 especially, as it seems, when the plant is occasionally dioecious. 



6. C. gracilis. Slender Shining Chara. 



Smooth, transparent, shining, without prickles. Whorled 

 branches acute, repeatedly forked ; often fertile, as well 

 as the axiUary compound ones. Bracteas none.
