22 botanical gazette. [January, 



scholtzia described by Professor Greene are all reduced to E. Californica, 

 for which fall reasons are given. The third part is-entitled " Miscellane- 

 ous Studies," chief among which is the discussion of Mimulus. The pro- 

 posal to divide the genus by restoring Diplacus and Eunanus to generic 

 rank is not approved, and the observations given, on the whole, confirm 

 Dr. Gray's conclusions, although they somewhat modify his sections. 



NOTES AND NEWS. 



W. L. GOODWIN, of Queen's University, Kingston, records {Can. Rec- 

 ord Sei., Oct.) the survival of a pine tree after girdling. 



Garden and Forest has begun an interesting series of articles upon 

 the elements of vegetable physiology, by Dr. George L. Goodale of Har- 

 vard University. 



Dr. Jultus von Sachs, the well-known professor of botany and di- 

 rector of the botanic garden at Wiirzburg, has declined a call to the Uni- 

 versity at Munich. 



Dr. David Dietrich, author of the extensive " ForstFlora " and 

 curator of the herbarium of the University of Jena, died on the 23d of 

 October, in the 90th year of his age. 



The last issued part of the Journal of the Linnean Society continues 

 Forbes' enumeration of the plants of the Chinese region. The list has 

 just reached the Composite. Many new species are described. 



In reviewing Wigands Das Protoplasrna als Fermentorganisynus, Dr. 

 Goodale {Am. Jmr. Jan.) refers to an expression the author once used in 

 conversation, " my whole life has revolved around Tannin, Darwinism 

 and Bacteria." 



In the Journal de Botanique (Dec. 16) Van Tieghem writes of hydro- 

 leucites and aleurone grains, and Lagerheim (of Stockholm) describes 

 (with colored plates) a new genus of Chytridiacese, parasitic upon the 

 uredospores of certain Uredineae. 



Mr. Arthur Hollick records (Bull Torr. CTu&, Dec.) the discovery 

 of Quercus heterophylla, the famous "Bartram Oak," at Tottenville, Staten 

 Island, N. Y , and in the same connection gives an interesting review of 

 the literature of this oak and also of Q. Rudlcini Britton. 



An abnormal Rudbeckia hirta is reported by 0. A. Far well, of Phoe- 

 nix, Mich., in which there are nine small head sessile in the axils of the 

 involucral scales of an ordinary head. They are 3 to 20-flowered, with 2 

 to 6 rays, and have an involucre of 3 to 8 equal scales in a single row. 



Dr. Bessey reports {Am. Nat. Dec.) that the notable weeds of the Ne- 

 braska plains are as follows, supposably in the order of their unpopular- 

 ity : Cenchrus tribuloides, Solan urn rostratum, Helianthus annuus, Hor- 

 deum jubatum, and the two tumble-weeds, Amarantus aibus and Cyclo- 

 loma platyphyllum. 



The Gazette discovers that it owes its readers an apology for the 

 miserable wrapping of the December number. The thing was so unus- 

 ual that it excited remark, and we do not wonder. Were it possible we 

 would duplicate the abused numbers. It was simply one of those mis- 

 takes for which no one seem to be blameworthy, but which will not oc- 

 cur again.
