the English East India Company, served in the Carnatic wars " : he 

 died at Lucknow, Sept. 13, 1800. Most of the drawings have been 

 named by William Koxbm-gh, who, in his Flora Iiidica, described 

 some new species from material sent by Martin, whom he com- 

 memorated in Andropogon Martini. 



The Journal of tJie Linnean Society (Botan}^ : xliv. no. 299 ; 

 July 31), contains "A Kevision of some Critical Species of Echinm,'''' 

 by C. C. Lacaita. Under this heading five papers are brought 

 together : 1. Five Critical Species — E. judceum, sp. n., E. austrule 

 Lam. ; E. Coincyanum, nom, nov., E. pycnanthum Pomel, E. salman- 

 ticum Lag. ; 2. The genus in the herbaria of Tournefort, Jussieu, and 

 Lamarck ; 3. The Echia of Sibthorp's herbarium ; 4. The Linnean 

 Species ; 5. The Echia of Miller's Gardener s Dictionary. Mr. 

 Lacaita has made an exhaustive study of the old material, not only in 

 the herbaria mentioned, but in the Sloane Collections and others in the 

 National Herbarium, and his paper is well described by him "as a 

 quarry from which any monographer of the genus may dig material." 

 The other papers in the number are " Plant-Distribution from the 

 Standpoints of an Idealist," by H. B. Guppy, and " On a Malay Form 

 of Ghlorococcum humicoW (with tw^o plates) by B. Muriel Bristol. 



The Essex Naturalist (xix. pt. 1 ; April 1918-June 1919) 

 contains an exhaustive account by Mr. Miller Christy of " Samuel 

 Dale (1659 P-1739) and the Dak Family " ; a note by Miss Lister 

 on Haheriaria chlorantlia var. tricalcarata ; a supplementary report 

 on the Lichens of Epping Forest by Robert Paulson and Percy 

 G. Thompson : and a description by W. G. Clarke of three Essex her-' 

 baria, one formed by John Freeman (1784-1864), and two by Joseph 

 Freeman (1813-1907) : the herbaria have been presented by Mr. W. 

 H. Freeman (grandson and son) to the Essex Field Club Museum. 



The last issue of the Becords of the Botanical Survey of 

 India (vol. vi. no. 8 ; Jan. 1919) contains an interesting paper by 

 Mr. C. C. Calder on "The Species of Occalis now wild in India." 

 These are nine in number — O. Acetosella, O. Griffith ii, O. variabilis 

 v-dLX. rubra, O. Pes-caprce, O. corniculata, O.puhescens, 0. tetraphyllay 

 O. latifolia, and O. corymhosa, of which the third, fourth, sixth, 

 seventh, eighth, and ninth are completely naturalized introductions ; 

 the naturalization of O. Bes-caprce is now reported for the tirst time. 

 Mr. Calder gives interesting details of the distribution of the species, 

 of each of which a plate is given. 



In The Ohio Journal of Science for April is continued the series 

 of papers dealing with the effect of the great eruption on Mount 

 Katmai in Alaska on plant-life and the remarkable recovery of vege- 

 tation around Kodiak "where the new plant covering consisted 

 almost entirely of old perennials which had survived and come up 

 through the ash." In the present instalment Mr. \l. F. Griggs 

 records the first stages of the process in the valley of Katmai liiver : 

 here one of the most notable survivals was Equisetum arvense, which 

 " was able to penetrate deposits so thick that nothing else could come 

 through." A series of illustrations from photographs add to the 

 interest of the paper.
