REPORT FOR 1912. 



253 



J. RiDDELSDELL. " Under var. petraeum^ Sm., I believe ; leaves thinly 

 hairy beneath ; racemes glandular-pubescent." — E. S. Marshall. 

 " Comes under var. Broyyifieldianum, Syme. The leaves are nearly 

 glabrous above." — G. C. Druce. 



Sedum Fabaria, Koch. [Ref No. 4910.] Tubney, Berks, July 

 1912.— G. C. Druce. 



Sedum Brucei, Graebner. [Ref. No. 5248.] Besilsleigh, Berks, 

 Aug. 1912. See Jieport 1912, pp. 160-162. Flowers shall follow next 

 season. — G. C. Druce. 



Sedum rupestre, L. Limestone crags, The Leete, Flintshire, v.-c. 

 51, July 22, 1912.- C. Waterfall. 



Callitriche palustris, L. [Ref. No. 146.] Stream, Ouchterlony, 

 Guthrie, v.-c. 90, N.C.R., Aug. 15, 1908. —R. and M. Corstorphine. 

 " Yes, the restricted C. venialis, Kuetz., and a new county record." — 

 G. C. Druce. "Only one specimen sent."— J. Cryer. 



Callitriche ? Silversprings, Kimble, Bucks, July and Sept. 



1912. — F. L. Foord-Kelcey. " No fruits present; probably C. verna." 

 — C. H. Ostenfeld. " The only fruit on my sheet has keeled (not 

 winged) lobes, and long, loosely reflexed, persistent styles ; these 

 characters point to C. polymorpha, Lonnr. The habit is that of a 

 large-leaved C. stagnalis.'' — E. S. Marshall. " On the specimen sent 

 I can find no fruit, and it is essential in the genus (except the 

 antumnalis section) to have fruit to safely decide. Still, by the 

 arrangement of the leaves, their structure, &c., I think this is 

 C. ohtusangula, Le Gall., but such specimens are never quite satis- 

 factory." — A. Bennett. " Probably G. verualis, but it is sterile, and 

 fruit is necessary for determination in this section." — J. Groves. 

 " I have known this plant in the above station for some years. I 

 have never obtained ripe fruit, but from its general appearance 

 I strongly suspect it may be C. polymorpha, which is now believed 

 to be a hybrid of stagnalis and intermedia." — G. C. Druce. 



Callitriche autumnalis, L. Marlee Loch, Perthshire, v.-c. 89, Aug. 

 1911. — M'T. CowAN, jun. ''Yes, the ordinary form of the species." — 

 A. Bennett. 



Callitriche truncata, Guss. Running stream, Grande Mare, Guern- 

 sey, Aug. 16, 1912. — W. C. Barton. " Yes, the plant recorded as 

 truncata, Guss., which I gathered in this locality where it is always 

 barren, but my Lancresse specimens show peduncled fruit, and they 

 probably belong, with the Westerham Kentish specimens, to var.
