312 THE JOUllNAL OF BOTAJfY 



Swaziland." " The plant is a very prolific seeder, and as the seeds are 

 so well adapted for wind distribution, it is no wonder that it is 

 spreading so rapidly. As the plant is a climber there appears to be 

 little danger of it invading the natural veld, but there is every possi- 

 bility of it becoming a nuisance in plantations, and it certainly is a 

 nuisance in gardens. The writer has seen poplar trees in Pretoria 

 covered with it, and if it is allowed to go unchecked will probably 

 smother them." 



We regret to record the death of Joha^ Oskab Hagsteom, 

 which took place at Vestra Emterwik, where he had been minister 

 since 1910, on June 7. He was born on May 21, 1860, at Bottna 

 in Sudermania, was educated at the University of Upsala, and 

 was ordained in 1885. In 1891 he began to study Potamogeton, 

 which he elaborated for Neumanns Sveriges Flora (1901) and Lind- 

 man's Sveml: Fanerogamenflora (1918). His most important work 

 was the Critical Researches on Potamogeton, published in 1916 in 

 Konigl. Svenska Vetenskap. Handl. Band 55 : this, written in Latin 

 and English, is the fullest and most careful publication on the genus, 

 and wiU always remain a tribute to his memory; it was noticed in 

 this Journal for 1918 (p. 115), where it is described as " essential to 

 botanists who wish to obtain a full knowledge of the genus." 



The contents of the most recent number of MalpigJiia (xxix. 

 fasc. v-vi) are mainly supplied by the editor, Dr. L. Buscalioni, who, 

 besides a continuation of his monograph of Sauraja, contributes a 

 paper " Sopra alcuni apparecclii per attenuare I'inquinamento del 

 pozzi delle Cisterne," and, with G. Raccella, " Intorno ad alcune 

 singolari anomalie delle radici di una plantula di Amggdalus com- 

 mtmis.'' In " Flora mediterranea australiore e Sahara," Dr. Nicotra 

 continues his researches on the Mediterranean floi'a. 



The Archivos do Jardi7?i Botnnico do Bio de Janeiro (1922) 

 contains the second part of A. Ducke's account of new or little-known 

 plants of the Amazon region. Numerous new species are described 

 and four new o-enera — Faracliimarrhis {Fuhiacece, allied to Chi- 

 marrlus), Jacqueshuheria {Ccesalpinece), LeCointea (Swarf ziete), 

 and Glycydendron {Crotonece) are established. There are twenty- 

 four plate's, mostly impressions from dried specimens ; dissections of 

 the flowers of the new genera are intercalated in the text. 



The Kew Bulletin (n. 6) contains a "host list" of South African 

 FolyporecB by P. A. van de Bijl, Professor of Phytopathology at 

 Stellenbosch, and a continuation of ''Decades Ke we n ses, '' 'mc\w(^mg 

 a new genus of Acanthacese {Isotheca Turrill) and of " Diagnoses 

 Africanse." 



The last part of the Contrihitions from the Gray Herbarium 

 (Ixiv. ; Ap. 18) is entirely from the pen of Dr. B. L. Eobinson ; it 

 contains an enumeration "of the Mikanias of northern and western 

 South America, and " Records preliminary to a general treatment of 

 the Fupatoriece,'' these being mostly of plants which have been 

 met Avith during the past year from various regions. 



The Orchid Review for September contains a paper, w^ith figure* 

 on Spiranthes Romanzojlana, by Col. Godfery.
