blue-green film from which dense, almost black, masses of various shapes 

 st:>od up vertically in the water." Useful tables are given, one illustrating 

 the periodical development of Alga in the tank near the Jodrell Laboratory, 

 and another dealing with the same subject for the lake. It is at once 

 seen that of the species enumerated only two are present throughout all 

 of the nine months that are included. These are Spirogyra crassa in the 

 tank by the Jodrell Laboratory and Aphanochcete repens in the lake.

Allium albopilosum. Anon. (Gard. Chron. No. 864, p. 34, & fig. 

 supplement, July 18, 1903). — This fine species was discovered by Sintenis 

 in 1901, growing on the mountain range that divides Transcaspia from 

 Persia. The flower-spike is about a foot in height, and bears an umbel 

 of about eighty flowers, which is about eight inches in diameter, the 

 individual blossoms being nearly two inches in diameter. They " resemble a 

 star with narrow rays ; their colour is a deap lilac with a metallic sheen." 

 " The leaves are glabrous on the upper surface, but furnished on the lower 

 and margins wdth many scattered white hairs, whence the specific name. 

 A botanical description of the plant is given in Latin. — G. S. S. 



Aloe Cameroni. By W. B. Hemsley (Bot. Mag. tab. 7915).— Nat. 

 ord. Liliacece, tribe Aloinece. Native of Eastern Tropical Africa. This 

 is an erect shrub with unbranched stem. Fbwers almost cinnabar- 

 red, yellowish above, pendulous. — G. H. 



Alpine Floral Effects, How to Produce, in large Gardens and 

 Parks. By Ed. Andre {Bev. Hort. October 16, 1903, pp. 469-72 ; Novem- 

 ber 1, 1903, pp. 493-4 ; and December 1, 1903, pp. 541-4). — A very interest- 

 ing series of articles on the principles to be followed in the establishment 

 of Alpine flowers or mosses &c. on an extended scale, also a list of 

 suitable plants. The general idea is the formation in gentlemen's parks 

 of large areas sown, rather than planted, with the Alpine flowers w T hich 

 afford such broad and splendid effects in their native fields. — C. T. D. 



American Florists' and Ornamental Horticulturists' Society 



(Proceedings of Ydth Anmcal Convention, Aug. 1903). — The society held 

 its annual convention at Milwaukee, Wisconsin, U.S.A., when the follow- 

 ing papers were read : "Floriculture at the St. Louis Exhibition," "Latest 

 Advances in Greenhouse Construction," "Decoration of Home Grounds," 

 "Floral Decoration," "Government Aid for Horticulture," "Violet Culture 

 in the West," "Substitutes for Coal " ("coal is the cheapest and best fuel that 

 the market affords "), " Humorous Side of the Florists' Business," " A System 

 of Accounts for Greenhouses, &c." The meetings, which extended over four 

 days, were interspersed w r ith concerts, sports, &c. The society includes 

 florists from most of the States, and in each State there is a vice-president, 

 who presents a report at the convention. One point is particularly worthy 

 of notice. A " Pa>ony Committee " was formed, with power to add to 

 its numbers. This power was interpreted in such a way that all members 

 of the society who were interested in Pa?ony cultivation were included in 

 the committer, thus forming a small special society under the main one. 

 This action seemed to meet with great and general approval. — F. J. C.
