is rather too sweeping. It is true that conclusions founded 



on microchemical methods are not so well based as those on quantitative 

 determinations. It is also true that when the conclusions of other in- 

 vestigators coincide with his own, Kraus should cite these with due 

 credit, which he too often fails to do. In this work, however, we have a 

 firm point of departure, and with these well sketched "Grundlinien" it 

 is to be hoped that the additions will be rapid until we can have the work 

 with the title, Physiologie des Gerbstoffs.

just completed III Teil, 1. Abteilung b, in six parts. It contains Phyto- 

 laccacese, and Nyctaginacese by A. Heimerl, and Aizoacese, Portulacaceae, 

 and Caryophyllacese by F. Pax. The chief changes among North Ameri- 

 can Nyctaginacese are that Oxybaph us is included under Mirabilis,and Pen- 

 tacrophys under Acleisanthes. The name Aizoacese may sound strange, 

 but it stands for our Ficoidese. Our genera of Portulacacese stand as 

 usual, but in Caryophyllacese the changes are numerous and radical. In 

 the first place, the Illebracese are brought back. Lychnis seems to dis- 

 appear from our native flora, our species being divided among Agrostem- 

 ma, Melandryum, Viscaria, etc. For instance, Lychnis GUhago Lam. be-

to find out. Moehringia is restored to generic rank, and another Arena- 

 ria, A. physodes DC, becomes Merckia physodes Fisch. Tissa Adans. re- 



places Lepigonum or Spergularia, as followed by Dr. Britton in Bulletin 



of Torr. Club (May). It will be a task interesting to some of our botan- 

 ists now to reconstruct our specific names on this new basis. 



A REVisroN of North American Rhamnacese has just been published 

 by Dr. Wm. Trelease, being a reprint from the Trans. St. Louis Acad. S»., 

 Vol. V, No. 3. The order contains 12 North American genera, and the 

 following changes from Watson's Bibl, Index are noted : Scutia disap- 

 pears, S. ferrea Brogn., becoming Condalia ferrea Griseb.; C. Mexicana 

 Schl. is added from Arizona; Reynosia latifolia Griseb. is added from b. 

 Florida; Rhamnus Insidus Kellogg, is included under R. crocea Nutt. , 

 Sageretia Wrightii Watson is added from New Mexico and Texas ; Coin- 

 brina reclinata Brogn, is added from S. Florida. 



Volume L,Part 6, of PUtonia (March-May, 1889), has an interesting 

 table of contents. This part completes the volume, which is suitably in- 

 dexed. The amount of botanical work represented by this first volume 

 may be inferred when it is known to contain 6 new genera, 180 new 

 species and 3 new varieties. This does not include the numerous trans- 

 ferred species. The present part contains the following papers : Vege-
