plant. May be 0. opaca. AVc must attend to tlie fresh state 
to see if the characters are correct, viz. ; — 
1. syncarpa. Nucules and globules coated with mucilage, 
spires of nucules broad flattened, faintly separated. 
2. capitata. Similar, but nucules with rather acute promi- 
nent spires. 
3. opaca. Nucules and globules naked, spu’es prominent. —

C. translucens, Pers. Pond near Woodford, S. Essex, June, 
1877. — H. Groves. 
C. intricata, Both. Pond, Kelvedon, Essex, June 10, 1877. — 
E. G. Varenne. 
C. crinita, Wallr. Swan Pool, Falmouth ; coll, by W. Curnow 
for Mrs. E. A. Lomax, August, 1877. Differs considerably from 
my specimens from Burdock Pool. I think it may be only a form 
of C.fcctida. — 0. 0. Babington. 
C. fcetida, Braun. The Lizard, W. Cornwall, September, 1877. 
Coll, by Mr. Curnow for Mrs. E. A. Lomax. C. fcetida. from the 
Lizard is curious, and worth more attention. It may be different, 
but I cannot now settle that point. It is apparently the plant 
from near Kynance Cove, which I named C. fcetida, var. densa of 
Cosson last year. It is more like Cosson’s figure (Atl. FI. de 
Paris, p. 37, f. 8) than the Kynance Cove plant. — C. C. Babington. 
“ 6’. Impida." Shallow pool on downs, Lizard, W. Cornwall ; 
August 25, 1877. — W. B. Waterfall. C. j)olyacantha, I believe. 
I so named what is apparently the same plant for Mr. Kalfs from 
“ rivulet on Lizard Downs ” last year. — C. C. Babington. 
C. aspera, Willd. Canal, near Pirbright, Surrey, August, 1877. 
— H. & J. Groves. I so named this plant for Mr. Groves last 
year. It is, I believe, the C. aspera, v. capillata of A. Braun. — 
C. C. Babington. 
C. frayilis, Desv. Stream near Lyndhurst, S. Hants, June 26, 
1876. — J. Groves. 
C. frayifera, Durieu. Pond, Lizard Downs, July 31, 1877. — 
J. Kalfs. Chy-an-hal, near Penzance, 1867. — J. Kalfs, also W. 
Curnow for Mrs. E. A. Lomax. I have noAV an admirable series of 
this beautiful plant.. “ C. frayilis, stagnant pool near Land’s 
End,” from Mr. Waterfall, is, I quite think, C. frayifera [as also is 
probably a plant which jMr. Townsend got at Tresco, in Scilly, in 
1862] . — C. C. Babington.
