Brassica integrifolia (West) O. E. Schulz var. carinata. (A. Br.) O. E. 
Schulz. 21, Middlesex; grown at Streatham from seed of plants col- 
lected at Tower Hill, Middlesex, in September 1950 and sown May 1951; 
flower July 16th 1951; fruit October 3rd 1951.- — J. E. Lousley. “ In 
August 1950 I noticed a few small plants of an unfamiliar Crucifer with- 
in the railings of a shrubbery at Trinity Square, Tower Hill, London, 
Middlesex, v.-c. 21, but was unable to obtain, a specimen for identifica- 
tion. The following month Miss E. M. C. Isherwood sent me two plants 
with ripe pods from the same place, and I sowed seed in my garden at 
Streatham the following May and pressed flowering material on July 
16th, and fruits on October 3rd 1951. In cultivation the plants grew to 
nearly a metre tall and were very different iii facies from the dwarfed 
specimens originally found. The very glaucous leaA^es (especially on the 
under surface), and the strongly veined, flattened, inflated fruits are 
conspicuous features. Vigorous weeding left no opportunity for the 
plant to reappear at Trinity Square in 1951. It is recorded from 
Abyssinia, Eritrea, Somaliland, and Tanganyika Territory and has 
previously been found on an air-raid shelter at Chelsea — see J . Bot., 79. 
86-7, 1941.” — J. E. Lousley.
