At the same meeting Mr. James Groves presented a paper on 

 Charophyta collected by Mr. Thomas B. Blow in Ceylon. He pre- 

 faced his remarks by referring to the great services Mr. Blow had 

 rendered in making large collections of these plants in the course of 

 travels in many parts of the world ; and to the great beauty and 

 excellence of the specimens, some of which were exhibited, due 

 to Mr. Blow's care and attention in floating them out, in spite of the 

 work having often to be done under very difficult conditions. The 

 first visit to Ceylon was in November 1895, when some of the plants 

 were immature, the second in January 1898, when they were in good 

 fruiting condition. The collection, by far the most extensive which 

 has been made in the Island, consisted of 13 species, one of which 

 was regarded as new. Only one of them occurred in Europe, the 

 rest being mostly confined to the tropical and subtropical regions of 

 the two hemispheres, and a few to Southern Asia and the Malay 

 Archipelago and the Philippine Islands. 



The New Phytologist (xx. n. 4 : Nov. 2) contains a continuation

 tions of three-and-a-half years on the growth and reproduction of the 

 alga3 of a pond near King's Norton, Birmingham ; and an article by 

 Dr. Fritsch on " Thalassiophyta and the Algal Ancestry of the 

 Higher Plants," based on Dr. Church's Oxford Botanical Memoirs 

 No. 3. 



The Botanical Gazette for October contains an interesting paper

 by J. C. Willis ; on the endemic species of the Canary Islands by 

 H. B. Guppy and on endemism in the Bahama Flora by Norman

The Naturalist for November contains a description by Mr. It.

 which at Adel, near Leeds, was briefly mentioned in our last issue 

 (p. 335). From the same number we learn of the death of Frederick 

 Arnold Lees, which occurred at his residence — Meanwood, Leeds, 

 on Sept. 17 ; we hope to give some account of his work later. 



The new part (Stuttgart, 1921) of Bibliotheca Botanica is 

 devoted to a continuation of K. Domin's " Beitrage zur Flora und 

 Pflanzengeographie Australiens." The orders treated (in Englerian 

 sequence) run from Casuarinacece to Amarantacece : many new 

 species are described, and there are four plates, with illustrations, in 

 m the text. We note that in Proteacece Knight's specific names are
