Plasmopara nivea, Schroe 
In 1917 this well-known antes on the U eo appeared 
on parsnips late in the season, _— noted abundantly near 
Wisbech in the end of September. In October Messrs. 
H. Wormald and E. W. Sow forwarded material from near 
Ashford and Haslemere respectively, and signs of its presence 
were observed later in several other — The fungus shows 
first as pale spots or ill-defined areas on the upper surfaces of 
the leaf with a delicate white mould peotmidiag below. With 
age the spots increase in size and become dark in colour, form- 
ing irregular blotches several centimetres across, similar in form 
and appearance to those caused by Phytophthora infestans in 
potato, a character which distinguishes it from any of the other 
diseases previously mentioned. In one garden near ‘Wisbech 
where parsnips were grown between fruit trees, a considerable 
amount of the foliage was destroyed by this fungus.

J. Hurcuinson. 
Amongst a donation of Canary Islands’ seeds for distribu- 
Se 
tion, Dr. G. V. Perez, of Orotava, Tenerife, has forwarded to 
Kew several pounds of “ Pagasaste,” Cytisus proliferus, var. 
palmensis,* Christ, ‘‘Gacia,”’ Cytisus stenopetalus, Christ, and 
** Gacia eee Cytisus pallidus, Poir. In various communi- 
cations to erez has repeatedly urged the importance 
of Canary Island fodder plants, especially the “ Tagasaste,” for 
planting in warm dry countries, such as North and South 
Africa, Festal tes and the near east; whilst ‘‘ Tagasaste’’ was 
the subject of a pamphlet by Dr. Perez’s father, Dr. V. Perez, 
and Dr. P. Sagot, published in’ Paris in 1892. The Kew 
Bulletin for 1891, pp. 239-244, contains a number of extracts 
from the Kew Reports giving particulars of the abt of 
‘*Tagasaste ’’ seed from Kew to various Colonies, and some of the 
results therefrom; and Sir Daniel Morris, in the Kew Bilin, 
1893, pp. 115-117, gave his own personal observations of the 
junction with the present notes. Recently Mr. J. H. Maiden 
has given a comprehensive account of the shrub in the Agricul- 
Gazette of New South Wales, for October, 1915, pp- 
a he 
mya the present paper treated as a separate species, C. _palmensis,
