localities which never fruits, and which I have always regarded 
as a sterile state of C. stagnalis growing in running water ; that 
species being usually a mud-dweller. — J. Groves. 
Oenothera rosea (Sol.) in Ait. Garden weed at Failand House, 
N. Somerset, August 1920. Dr. Rendle writes: “A native of 
Mexico, S. United States and S. America; it occurs as an alien 
in the Canary Isles and S. Europe.” — J. W. White. 
Danaa comubiensis Burnat. Burnham Beeches, Bucks, Aug. 28, 
1920. — W. R. Sherrin and L. B. Hall. The plant was very 
abundant, but the continuance of the species here is threatened, 
as the wood is being cleared. 
Garum verticillatum Koch. [469]. Boggy meadows, Colbren, 
W. Brecon, v.c. 42, Aug. 31, 1920 Recorded from the locality 
in “Journ. Bot.,” 1885, p. 86. — W. C. Barton. 
Galium Molluyo L. var. Bakeri Syme. Roadside between 
Birsay and Dunkadale, Mainland, Orkney, 4 Aug., 1920. — R. J. 
Burdon. Pending some note on this plant (I have seen no speci- 
men), see last Report, p. 104, where C.E.S. says Bakeri is “ better 
placed as a var. of G. eredum .” — H.S.T. 
G. saxatile x asperum 1 Growing with or near both parents 
on limestone ground north of Cheddar Gorge, N. Somerset, v.c. 
6, June 24, 1920, alt. c. 700 ft. Turns black on drying, like 
saxatile ; leaves otherwise more like those of asperum. One 
species seemed to-pass imperceptibly into the other, saxxitile being 
on the grassy ground further from the slope of the Gorge. See 
interesting article by Tansley in “Journ of Ecology,” Dec. 1917, 
“ On competition between G. saxatile L. and G. sylvestre Poll, on 
different types of soil.” — H. S. Thompson. Is any asperum 
apparent ? The texture of the basal leaves is that of saxatile , the 
ovaries (there are no ripe fruits on my two examples) show 
evidence of the characteristic tubercling of the fruit of that 
species, and the upper leaves of saxxitile are often as narrow and 
acute as in these specimens. — C. E. Salmon. Mr. Tansley prefers 
to withhold suggestive remarks upon this plant until after 
further culture and investigation at Cambridge. — H.S.T. 
Cirsium tuberosum Allioni ( Cnicus tuberosus Roth.). Rough 
pasture on coast, Nash Point, Glam., v.c. 31, Aug. 29, 1920. — 
H. S. Thompson. 
C. arvense Scop. [475]. By R. Wye in shade, Boughrood, 
Radnor, v.c., 43, Aug. 30, 1920. Growing on hood deposit. All
