but of a fresh water sponge. The Nostocs must still stand respon- 

 sible for the "pig-pen" odor, but the "cucumber odor" we hand over 

 to^zoologists. 



Mr. Foerste, of Dayton, Ohio, writes that he has received a 

 postal card from Mr. Wm. Trelease saying: "I have noticed pro- 

 togyny in Thaspium aureum and Sanicula, so I no longer have 

 any doubt as to the accuracy of your observations on Erigenia, 

 though the fact of this sort of dichogamy occurring in UmbeUiferce 

 was entirely unexpected from the uniformity of protandry in the 

 earlier studied genera. 



The Proceedings of the Davenport Acad, of Nat. Sci., Vol. 

 Ill, Part II, are at hand. The botanical articles are by Prof. J. C. 

 Arthur and Dr. C. C. Parry. The former makes still farther addi- 

 tion to his catalogue of Iowa Plants; while the latter describes two 

 new species of Oxyiheca from Southern California. The new species 

 are named 0. caryophylhides and 0. Parishii and were both 

 discovered by the brothers Parish in the San Bernardino Mountains. 



On page 78 of the July Gazette it might be inferred that 

 Baillon's work among the Compusitce was thought more commend- 

 able than even that of Mr. Bentham. No reader of the Gazette 

 should labor under such a delusion. Because Mr. Bentham with 

 immense labor has worked up the vast order and acknowledged 780 

 genera, and Baillon, putting a good part of the genera shown to be 

 near mto one, reduces the number to 403, is no indication that the 

 work of the hitter is either "philosophical or practically conven- 

 ient," for it is very easy work to do. 



Prof. Henry G. Jesup, of Dartmouth College, has published 

 a very handsome pamphlet entitled "Flora and Fauna of Hanover, 

 N. H." The list of plants includes the flowering plants and higher 

 cryptogams, just such as are included in Gray's Manual. The 

 range includes the flora within thirty miles radius of the town of 

 Hanover and contains a great diversity of conditions, such as 

 mountain peaks, valleys, and lakes, and, as is to be expected, the 

 list is an exceptionally rich one. Tbe summary shows a total of 

 1008 species, of which 286 are Polypetahe, 265 Gamopetalw, 96 

 Apetalce, 52 Cryptogams Introduced phgenogams number 144:. 



Mr. J. M. Macfarlane, Demonstrator of Botany in the Uni- 

 versity of Edinburg, finds a new factor in the vegetable cell, which 

 he proposes to call the nucleolo-nucleus. It is a well marked body 

 inside the nucleus, round or slightly oval in outline, aud exhibits a 

 clear bounding wall differentiating it from the substance of the 

 nucleolus. It was first seen in the epidermal cells of Omithogalum 

 pyramidale, after staining fresh epidermis with a | per cent, solu- 

 tion of eosin in common methylated spirit, and was afterwards 

 found in many other Phanerogams and also in some Cryptogams. 

 Mr. Macfarlane concludes that the nucleus, nucleolus and nucleo- 

 lo-nucleus are invariably present, if the cell is still act ire.
