 paper brings the scattered material together, 179 species being enumer- 

 ated, 29 of which are new. 



A rust of carnation pinks {Uromyces caryophyllinus Schroet.) has ap- 

 peared in several places in Indiana, and threatens to be a serious pest 

 to florists. It was brought to the attention of Dr. J. C. Arthur the 

 middle of last month, and investigations show that it is already well 

 distributed in the state, some large greenhouses not having a plant free 

 from it. It has long been known in Germany and southern Europe, 

 but this is believed to be the first time it has been reported in this 

 country. 



Prof. Lucien M. Tnderwood, of DePauw University, Greencastle, 

 Ind., has decided to devote his time exclusively to botany, and offers 

 his entomological library for sale. It contains sets, mostly complete, 

 of American serial publications, the nine Missouri reports by Riley, 

 bound in 2 vols., with index; Fitch's fourteen reports bound in 3 vols., 

 with MS. index; Low & Osten Sacken's Diptera complete, and many 

 other rare and valuable works. It also includes the nearly complete 

 literature on N. A. Arachnida. 



The Orcutt Seed and Plant Co., San Diego, Calif., announce the 

 preparation of herbarium specimens of all cultivated plants, which 

 they intend to test at San Diego. The labels will give botanical and 

 vernacular names, descriptions drawn from the fresh plant, color, 

 historical, economic and cultural notes. It is hoped that botan- 

 ists and horticulturists will lend assistance to the work, as cultivated 

 plants are generally neglected in herbaria. 



The Royal Danish Academy of Sciences at Copenhagen offers two 

 prizes of 400 and 600 kronen, respectively, (a) for investigations on the 

 sorts and proportions of the more important carbohydrates present at 

 different stages of ripeness of the four chief cereals; and (b) for in- 

 vestigations of the Phytoptus galls which are found in Denmark with a 

 monographic treatment of the species of the genus of insects produc- 

 ing them. The latter investigation is desired especially to clear up 

 the question as to whether on the same species of plant a given species 

 of Phytoptus may produce different galls at different stages of its de- 

 velopment. The prizes are to be awarded in October, 1893. 



Some recent researches by Drs. Frank and Otto, of Berlin, have 

 shown that the green leaves of plants are at evening richer in nitrogen 

 than in the morning, and that the leaves themselves show an accumu- 

 lation of nitrogen, when they are separated from the plant, placed in 

 water and exposed to the direct sunlight. These investigators deduce 

 from their results some conclusions as to the harvesting of plants for 

 fodder (such as clover) which need testing on a practical scale. Thev 

 recommend the cutting of clover late in the day, preferably toward 

 sunset of a warm, clear day, in order that the greatest amount of the 

 nitrogenous foods, which have the highest nutritive value, may be 

 secured.
