Synopsis of the North American Amaranthacese, 

 III.: Edwin B. Uline and Wm. L. Bray. An 

 enumeration of the North American species of 

 this order, 'with synonymy and remarks upon 

 the recognized sisecies and varieties, together 

 ■ with descriptions of new ones. The genera 

 Frcelichia, Gossypianthus, G-mlleminia, and Clado- 

 thrix are treated in this installment. Frcelichia 

 interrvpta cordata, Gossypianthus lanuginosus 

 Sheldoni and Guilleminia densa aggregata are de- 

 scribed as new. 



Notes from my Herbarium, III.: Walter 

 Deane. In this note Mr. Deane describes his 

 methods of mounting plants. As his herbarium 

 is remarkable for the beauty of the specimens 

 his advice on these matters is especially valu- 

 able. 



Some Euphorbiacese from Guatemala: John P. 

 LoTSY. The last representatives of this order 

 from Guatemala acquired by Capt. John Don- 

 nell Smith are here enumerated by Dr. Lotsy. 

 Euphorbia rubrosperma, E. microappendiculata, 

 E. leucocephala, E. chamsepeploides, Croton elute- 

 rioides, C. Guatemalensis and Tragia Guatemalen- 

 sis are described as new. On two double plates 

 three of these new species are figured. 



Vegetal dissemination in the genus Opuntia : J. 

 W. TuoMEY. Professor Tuomey calls attention 

 to the fact that the persistency with which these 

 cactuses retain their moisture flts them for vege- 

 tal dissemination. The prostrate flat-jointed 

 forms spread by rooting where they touch the 

 ground and having the older parts die away, 

 while the cylindrical erect forms have barbed 

 spines by means of which their joints are trans- 

 ported. Few depend upon seed dissemination. 



A study of some Anatomical Characters of North 

 American Gramineie : Th. Holm. In this paper 

 , the author concludes the examination of the 

 species of Leersia and enumerates the anatomi- 

 cal characters of the leaves by which they can 

 be discriminated. 



Daniel Cady Eaton : George E. Davenport. 

 This is a short but appreciative biographical 

 sketch of the late Professor Eaton, by one who 

 has long been associated with him in the critical 



*Issned August 15, 1895. 40 pp., 5 pi. 



study of the ferns. A portrait accompanies the 

 sketch. 



The Nomenclature Question : A Further Di.?cus- 

 sion of the Madison Sides : B. L. Robinson. Dr. 

 Robinson replies to Mr. Co\'ille's criticisms in 

 the July number and again vigorously attacks 

 the doctrine of 'the rejection of thehomonyms.' 



Among Briefer Articles is one describing a 

 new genus of Umbellifei'se fi'om Mexico, which 

 the authors. Dr. John M. Coulter and Mr. J. 

 N. Rose, dedicate to Mr. Walter Deane under 

 the name of Deanea, with two species, D. nudi- 

 cauUs and D. tuberosa ; and one by Dr. Tre- 

 lease, asking for information in regard to the 

 distribution of our species of pignuts. An Edi- 

 torial \'igorously defends the Gazette against the 

 charge, by an auonymous correspondent of the 

 Journal of Botany, of suppressing free discus- 

 sion of the nomenclature question. Under Cur- 

 rent Literature Mr. Charles Robei'tson reviews 

 MacLeod's 'Fertilization of Flanders Flowers,' 

 and the editors notice a new issue in Ostwald's 

 ' Klassiker der exakten Wissenschaften. ' Two 

 pages of Notes and Netvs conclude the number. 



PSYCHE, SEPTEMBER. 



W. S. Blatchlby continues his account of 

 the winter insects of Vigo county, Ind., adding 

 26 more species of Hepteroptera. G. B. King 

 finds from repeated observations of frozen nests 

 that Formica obscuripes does not retreat into the 

 lower parts of the nest in winter, but remains 

 practically in all parts excepting close to the 

 surface, though, of course, wholly inactive ; 

 some of the parasites are noticed. In a supple- 

 ment, T. D. A. Cockerell describes a couple of 

 new bees and some new Coccidse and adds a note 

 on a Mutillid which ' as it runs over the ground 

 . . . looks extremely like a bit of thistle down 

 blown by a gentle breeze.'
