other botanists, and generously placed at their disposal the 
material and information which he had collected. Among scien- 
tific papers written at his suggestion or based on his work, the 
following may be mentioned :—The Statices of the Canaries of the 
Subsection Nobiles (Ann. Bot. xx. pp. 205, 301); Echiums from 
the Atlantic Islands (Kew Bull. 1914, pp. 116, 265); Tagasaste

Witttam Tyson.—We record with regret the death of Mr. 
William Tyson, which occurred at Grahamstown on April 14th, 
1920. Though born in Jamaica in 1851, Mr. Tyson belongs essen- 
tially to South Africa, where for many years he was an ardent 
plant collector. As early as 1877 he began collecting near Port 
Elizabeth, and in subsequent years he made extensive additions 
to his store, both when on tour with the Superintendent of Woods 
and Forests and during periods of residence in a number of dis- 
tricts. His field included the Karroo, the Cape Peninsula, East 
Griqualand, Pondoland, and the district round King William’s 
own. His collection supplied the material for several new species 
as well as for the genus Tysonia. Some hundreds of the East 
Griqualand and Pondoland specimens are at Kew, while the 
Herbarium Normale Austro-Africainae was considerably enriched 
as a result of his efforts. A record of Mr. Tyson’s correspondence 
with Kew reveals his keen interest in the welfare of the Cape, as 
i by his scheme for tree-planting in the Murraysburg 
district. In latter years he resided at Port Alfred, and specialised 
in marine algae, his interest in which prompted a recent visit to 
the Pondoland coast; he hoped also to increase his hanerogamic 
collection, but ill-health unfortunately hampered his activities.
