Stem of Monocotyledons, The Formation of. By J. C. Schoule 

 (Flora, vol. xcii. 1903, pp. 32-48, T. iv.).— The growing point of all mono- 

 0 ityledona is a thick cone ; but as its primary growth is slow, the stem at first 

 formed by it is thin. Owing to a gradual increase of the diameter of the 

 growing point in the Palm type, the lower part of the stem forms an inverted 

 rone. Tin greater part of the wide base of the adult growing point is 

 occupied by a cambium, in which parenchyma and fibro vascular bundles 

 are formed on the inner side. In the arborescent LUiifhra this cam- 

 bium layer is continued down the stem, and by its intensified growth below 

 0 'ii verts the inverted cone into a cylinder. The author gives interesting 

 measurements and references. — M. II. 



Stigeoclonium. Youngr Plants of (Bcih. Bot. Cent. xiii. ht. 4, 

 p. H68 ; 2 plates). — Dr. F. E. Fritsch describes the development of this 

 Alga from specimens obtained in Kew Gardens. A new variety is also 

 described. Those Herposteiron species which have distinctly septate 

 hairs are believed to be stages in the life history of the above genus. 

 Endoderma species (epiphytic and endophytic) may also be connected 

 with Stigeochmum spp. A bibliography is given. — G. F. S.-E. 



Strawberry, A new Pest of the. By F. L. Washburn (U.S.A. 



Jlort. Soc. Minnesota, Rep. 1002). — The beetle Harpalus pennsylvanieus, 

 hitherto looked upon as a carnivorous beetle, has developed a taste for 

 Strawberries. Other species of the genus H. caliginosus in Ohio (1900) 

 and H. ruficornis in Holland and in England (see Miss Ormerod's 

 Reports 1894-95 and 1897-99) are also reported as injuring Strawberries. 

 A lantern trap is suggested as a means of attracting the insects ; hand 

 picking from under the mulching or from under boards placed on the 

 earth is also recommended. — F. J. C. 



Strawberries, Tests of. By O. M. Taylor (U.S.A. Exp. Stn. New 

 York, Bull. n. 218, November 1902 ; 1 plate). — A minute account of 

 experiments with fifty-six varieties of Strawberry on the Station grounds 

 at Geneva, with tables of temperature and rainfall, and of season and 

 yield in the Strawberries under observation. 



The records were made in 1902, when several late frosts did serious 

 damage to the blossoms even in the early bud stage. On the other hand, 

 the rainfall was ample during the fruiting season, so that the plants at 

 DO lime suffered from lack of moisture, which doubtless increased the 

 yield of some of the varieties. The plants were, whenever possible., 

 procured from the introducer or originator to ensure their being true to 

 mime, and were planted in the spring of 1901, but not allowed to fruit 

 that year. 



The tests proved ' Crescent ' to be the largest and heaviest bearer, and 

 tlim.fmv. ronsidering the season, probably also the hardiest. No very 

 earl; variety was grown, bat ' Crescent ' was one of about nine which were 

 ready for a first picking by June 18.— M. L. H.
