A leading figure among Colonial botanists has lately been 

 removed from us in the person of George Henry Kendrick 

 Thwaites, for many years Superintendent of the Eoyal Botanic 

 Gardens, Peradeniya, Ceylon. Mr. Thwaites was born at Bristol 

 in 1811, and was in early life engaged as an accountant in that city. 

 He soon turned his attention to entomology and botany, his first 

 botanical note, on the occurrence of Asplenium lanceolatum near 

 Bristol, appearing in the ' Phytologist ' for October, 1841. In 1846 

 he published, in the ' Annals and Magazine of Natural History,' a 

 note " On the occurrence of tetraspores in Alg^e," this being the 

 first of a large number of papers on the structure and life-history 

 of the lower cryptogams, in which Mr. Thwaites showed his capa- 

 bility for careful and original work. Of these papers, those on the 

 process of conjugation in the DidtoJiiaccte are especially important ; 

 and in recognition of his work Montague, in 1845, dedicated to him 

 the genus Tlucaitesia, It was about this time that he marked for Mr. 

 Watson a 'London Catalogue,' indicating the flowering plants seen 

 within ten miles of Bristol, Avhich is quoted for North Somerset and 

 West Gloucester in ' Topographical Botany.' On the death of Mr. 

 Gardner, in 1849, Mr. Thwaites was appointed his successor as 

 Sui)erintendent of the Peradeniya Gardens, — a post which he filled 

 until the appointment of Dr. Trimen in 1879. On his arrival in 

 Ceylon he at once devoted himself to an investigation of the flora of 

 the Island. From 1852 to 1856 he contributed descriptions and 

 figures of new Cingalese plants to Hooker's ' Journal of Botany'; 

 and in 1858 issued the first part of the ' Enumeratio Plantarum 

 Zeylaniae,' which was completed in five j)arts, the last appearing in 

 1864. This, which contains descriptions of a large number of new
