1982. Anonymous. The American holly. Nation. Nurseryman 29^: 33. 1921. — This 

 plant has withstood the smoky atmosphere of St. Louis better than most other plants. "For 

 a city evergreen the holly is therefore recommended above all other evergreens on account of 

 its smoke-resisting qualities." — Attention is called to the general dioecious habit of the plants 

 and the consequent necessity of planting staminate and carpellate trees close together in order 

 to secure pollination. — / H Gourley.

1985. Albert, C. Le fenouil de Florence: II Fenochio. [Fennel from Florence, II Feno- 

 chio.] Rev. Hort. 92: 220. Fig. 56. 1920. — Differing from the common fennel, the leaf 

 bases of this variety produce a scaly bulb, the interior of which is tender and edible. It is 

 used in either the cooked or uncooked state. Seeds sown in March produce marketable plants 

 in June and July, while those sown in September yield large plants the following April.—

1986. Enfer, V. Chauffage des serres: les lignites et la tourbe. [Heating greenhouses: 

 lignites and peat.] Rev. Hort. 92: 218-219. 1920.— Both of these materials may be used as 

 substitutes for coal, the latter when used in conjunction with coal or when made into bri- 

 quettes, is a good fuel. Large quantities of peat are available at many places in France. —

1987. Enfer, V. Utilisation des serres avec chauffage: production des legumes. [Utili- 

 zation of greenhouses with heat:, production of vegetables.] Rev. Hort. 92: 195-196. 1920. — 

 Specific suggestions on growing various crops. — E. J. Kraus. 



1988. Gadeceau, E. Le drapeau beige: Abutilon megapotamicum. [The Belgian flag— A. 

 megapotamicum.] Rev. Hort. 92: 214-215. 1 pi (colored). 1920.— This form is dedicated to 

 King Albert I of Belgium because the colors of the flower are arranged as are those of the 

 Belgian flag; the calyx is red, the corolla yellow, and the stamen mass brown-black. The 

 plant is free flowering and of easy culture. — E. J. Kraus. 



1989. Heede, A. vanden. Les plantes vivaces et rustiques : les juliennes a fleurs doubles. 

 [Perennial and hardy plants: double flowered Hesperis.] Rev. Hort. 92: 198. 1920.— The 

 single flowered forms of Hesperis maironalis generally persist from year to year. The white, 

 double flowered form, however, usually dies out the 2nd year following planting. This diffi- 

 culty can be completely avoided by dividing the old plants in August, or by making cuttings 

 from the stems, and transplanting to a new situation. — E. J. Kraus. 



1990. Krelage, E. Nouvelles tulipes hybrides. [New hybrid tulips.] Rev. Hort. 

 92: 196-197. 1 pi {colored). 1920.— Systematic hybridizing of tulips was undertaken 20 

 years ago. Crossing Tulipa retroflexa with a rose colored Darwin tulip resulted in a variety, 

 Sirene, with distinctly reflexed petals, flowering for the first time in 1908. Other varieties with 

 similar lily-like flowers, in various colors, are being produced each year. Three other distinct 

 groups of varieties are listed as follows : (1 ) Pure white forms particularly adapted for forcing ; 

 (2) forms possessing absolutely new colors or attractive combinations of colors; (3) yellow 

 varieties of the true globular Darwin type, of which none existed previously. Many of the 

 varieties are still on trial, many hundreds have been discarded, and each year many new 

 seedlings bloom for the first time. — E. J. Kraus.
