268 HORTICULTURE [Bot. Absts., Vol. VI, 



1851. Krelage, E. A propos de la classification des Tulipes. [Concerning the classifi- 

 cation of tulips.] Rev. Hortic. [Paris] 92: 30-31. 1920. — Corrections of an article by Mottet, 

 S. (Les tulipes Darwin. Rev. Hortic. [Paris] 92: 10-11. Jan., 1920.) Figure 4 of the colored 

 plate does not represent the variety Goldflake, which is red striped with yellow, but rather 

 some variety belonging to the class known as "bizarres." Instead of representing several 

 varieties of Darwin tulips, as the legend indicates, the plate actually shows clearly the dif- 

 ferences between the Darwins and other late tulips. The varieties Rev. Ewbank and Europe, 

 with flowers more or less square and enlarged at the base are typical of the Darwins, to which 

 Margaret also belongs, but it is not so well figured. Inglescombe Yellow, with elongated 

 flower, belongs to the Cottage class. The yellow color is never found among Darwin tulips. 

 A report based upon a study in 1914 and 1915 of varieties grown under more than 1500 names 

 in the gardens of the Royal Horticultural Society of London was issued in 1917. It is the work 

 of a joint committee from England and Holland, and contains many illustrations as well as a 

 system of classification of the various varieties. — E. J. Kraus. 



1852. Lesotjrd, F. Campanula pyraversi Cayeux. Rev. Hortic. [Paris] 92: 124. 1 plate 

 (colored), fig. 32. 1920. — This form was obtained by Mr. F. Cayeux as a hybrid between 

 Campanula pyramidalis L. and C. versicolor Sibth and Smith, whence the name. It is self- 

 fertile, and likewise fertile with either of the parent species. The hybrid possesses characters 

 derived from both parents, but in the long petioles of the radicle leaves and the well devel- 

 oped pedicels of the flowers it resembles neither. Because of its desirable tints of blue color, 

 darker at the center, long blooming season, and adaptability for growing in beds, in masses, 

 or in pots, it should be generally cultivated. — E. J. Kraus. 



1853. Lesotjrd, F. Contribution a l'histoire de la pyramide. [On the history of the 

 pyramidal tree,] Rev. Hortic. [Paris] 92: 81-82. 1920. — Though incapable of exact determi- 

 nation, it appears that the pyramidal type of tree originated in Lorraine, near Metz, at 

 an early date and spread from there eastward and westward, reaching the region of Paris 

 about the middle of the eighteenth century or a little later. Several direct literature citations 

 are given. — E. J. Kraus. 



1854. Letacq, A. Notes sur la culture du Camellia dans l'ouest de la France. [On the 

 culture of Camellia in western France.] Rev. Hortic. [Paris] 92 : 120-121. 1920. — It is possible 

 to grow Camellia japonica L. throughout an extensive territory in France. The plants must 

 be protected in the more northern ranges, but are perfectly hardy in the south. It is especially 

 to be noted that silicious soils are the most favorable to good development, whereas in cal- 

 careous soil the plants soon turn yellow and die. — E. J. Kraus. 



1855. Lillie, R. I. Flowers. Hawaiian Forester and Agric. 17:6-9. 1920. — Discusses 

 factors involved in successful flower growing, grouping them under four heads: (1) seasons; 

 (2) seeds; (3) sowing; and (4) soil. Practical for amateurs. —Stanley Coulter. 



1856. Loizeau, A. Jardin en campagne. [A country garden.] Rev. Hortic. [Paris] 92: 

 51-53. Fig. 12. 1920. — The discussion deals with the general arrangement of country gar- 

 dens, and the location of specimen plants, groupings, and borders. A selected list of materials 

 and proposed plan are submitted. — E. J. Kraus. 



1857. Morel, F. Les benefices d'une calamite : Laurier de Serbie et Pyracantha pauci- 

 flora. [The good fortunes out of a calamity. Serbian laurel and Pyrocantha pauciflora.] 

 Rev. Hortic. [Paris] 92: 80-81. 1920.— The Serbian laurel, Laurocerasus schipkaensis, proved 

 entirely hardy during the severe winter of 1917. A number of the hybrid seedlings of this 

 species and the Caucasian laurel also proved perfectly hardy. These forms were very vari- 

 able in character, some of them being worthy of propagation. Pyracantha pauciflora, while 

 entirely hardy, normally produces few flowers or fruits and is, to that extent, lacking in 

 decorative qualities. A number of seedlings of it, however, have not only proven perfectly 

 hardy, but also highly productive of both flowers and fruits. These should prove of great 

 value as ornamentals. — E. J. Kraus.
