88 Mr. C. C. Babington on the British species of Chara. 



which I am indebted to Mr. Borrer ; and as it does not seem to 

 have been noticed elsewhere, I have ventured to record it as a 

 new species, and honour it with the name of my valued friend. 



In a marsh ditch at Henfield, Sussex, Mr. Borrer. 



Annual. July. 



10. C. polyspermia (A. Br. !) ; monoecious, stem slender equal 

 flexible transparent, branchlets finely pointed those of the pri- 

 mary whorls sterile once or twice unequally branched : middle 

 subdivision longest, the other branchlets on axillary branches 

 numerous densely crowded much subdivided with short inter- 

 nodes, nucules and globules placed at the nodes of the branch- 

 lets " between the lateral rays " (or bracts ?) .

Sc. Nat. ser. 2. i. 352 ; Mutel Fl. Franc, iv. 162. 

 C. fasciculata, " Amici" A. Braun. 



A small plant resembling the preceding species, and having 

 like them bird's-nest-like masses of branchlets. My specimens 

 are slightly incrusted, as is stated to be the case in those found 

 in France. Nucules small with faintly marked striae. Granules 

 small. 



I gathered this species in the year 1833 near Haslingfield in 

 Cambridgeshire, but have not been able to find it there again. 

 As numerous specimens were obtained by a party at that time, it 

 is probably preserved in many collections under the name of C. 

 nidifica, with which denomination it was sent to Prof. Braun and 

 named by him as above. Mr. Borrer possesses specimens found 

 at Livermere near Bury St. Edmonds by the Rev. G. R. Leathes. 



Annual. April. 



Section II. Chara. Crown of the nucule of " five cells forming 

 a simple circle and sometimes spreading, persistent " (A. Braun). 

 Stems usually coated with smaller tubes. 



Charce vera. Granule taking the place of one of the bracts. — 

 Diplostephana (A. Br.). A double row of spines (stipules) 

 at the base of each whorl. 



a. Stem coated with as many tubes as there are branchlets in each 

 whorl. — Branchlets coated. 



11. C. crinita (Wallr.) ; dioecious, stem slender coarsely striated 

 thickly beset with setaceous patent clustered spines, branchlets 

 abbreviated, bracts whorled slender equal, nucules narrowly ob- 

 long shorter than the bracts. 



C. crinita, Wallr. Ann. Bot. 190. t. 3 ; A. Braun in Flora, xviii. 70 ; 



Ann. Sc. Nat. ser. 2. i. 355 ; Mutel Fl. Franc, iv. 165.
