OBSERVATIONS UPON BRASSICA BRIGGSII, Wats. 
By E. G. Varennz. 
In the summer of 1880, during a visit to the West of England, 
in 
said was known by the name of Charlock or Garlic. He 
observed that it was a great pest all over the cultivated land of the 
> aerate and had been known as such during the memory 
an. 
The plant thus indicated by Mr. Curnow had neither the 
botanical characters nor don habit of growth of Sinapis arvensis, L., 
the Charlock which is so well known as an abundant weed in the 
corn-fields of the Hast ah: England. It agreed, however, igs) 
well with Sinapis siete. L., by being very abundan in the 
localities in which it grows, in being difficult of extirpation, ha 
also in being an old-established weed. 
On further examination and investigation, this Newlyn plant 
turned out to be an annual Brassica, with a slender tap root, 
agreeing in its botanical characteristics fe that which has been 
named Brassica Briggsii by the lat Watson. It certainly 
bears a great resemblance—as Mr. Water also thought—to the 
Brassica hig’ angie L., as it is ‘elineated in Plate 2234 of ‘ English 
Botany.’ But @ flowers of Bra a Briggsii ave true turnip- 
flowers, of a oon brighter bet oh class than are those of 
B. Sieatiggs A in the ‘English Botany’ plate. 
Some of the seeds of Brassica Briggsii brought to Kelvedon 
from Newlyn last year were sown in a garden-pot in the early part 
of the spring-time of the present year. They soon vegetated. 
the vey young growth of the plants the first leaves which appeared 
after the ee hg leaves had fully formed were green m 
colour, and beset with a number of bulbous caducous hairs. 
About Keema time the plants were fairly in foliage,
