‘OBSERVATIONS UPON BRASSICA BRIGGSII. 861 
showing the upper glaucous leaves and the bright es flowers, 
and having plenty of seed-pods formed. Unfortunately an 
amateur gardener picked up the ‘eterna things re weeds, so 
that the opportunity of hatte, a fresh supply of seeds was lost. 
However, enough had b een to warrant the conclusion that 
Brassica Briggsit was not a Save 1 plant. 
ome very young specimens of these seedling Brassicas were 
in the middle of May, and another specimen to Mr. Bri oe er 
Plymouth. 
Mr. Watson, as the readers of this Journal well know, first 
ani out the fact that turnip-Brassicas are easily distinguishable 
from rape- and cole-seed, when very young, wai a colour of the 
es 
of the young Brassica Briggsii sent to him. The remarks Mr. 
Watson made concerning the young leaves, in a pores received 
from him, were to the effect that ‘‘the Brassica is Brassica Briggsit, 
I suppose ; its pei green colour quite well jails it from 
Napus and Ruta 
Mr. Briggs lies the young leaves which he received from 
me to be similar to those grown from the a of the B. Briggsit 
which he met with at Torpoint, Cornwall, in 1878. 
On visiting Penzance again towards the Bi of the past July, 
it was plain enough that the first crop of Brassica Briggstt had been 
destroyed when the summer produce of the fields was lifted a nd 
carted away ; but very soon afterwards, in the month of August, 
shane sag’ young turnips about dung-heaps and by the side of 
rn-fields, Brassica Briggsit sprung up very quickly, and it showed 
itself ace at the end of the month. Growing freely 
am onget the summer-sown turnips, it was a trouble to the boys

up ane which were the cultiv at plants to be allowed to remain.

Yeo, Devon, in 1870, it had not attracted the notice of botanists in
