article gives some remarks on the plants which bear, or have borne, the 

 name of Rose, with much interesting information as to the derivation of 

 the name which will prove very useful to lovers of plant-lore. — G. S. S. 



Rubus moluccanus (Die Gart. p. 431, June 6, 1903).— This 

 species inhabits the Himalaya, Burma, &c. Being very variable in its 

 foliage, it is known under several names, mostly B. reflexus, but its proper 

 specific name is B. moluccanus. In general appearance it resembles a 

 climbing or trailing Begonia. The stem and leaf- stalk are covered with 

 brownish hairs. The palmate leaves are nine inches long and broad, 

 slightly dentate ; the central part is dark green while the margin is of a 

 much paler green, and pilose beneath. It is a fine plant for the temperate 

 house. — G. B. 



Salt-Marshes of the Bay of Fundy, An Ecological Study (with 

 16 figs, and maps). By W. F. Ganong (Bot. Gaz. vol. xxxvi. No. 3, p. 

 161 ; No. 4, p. 280 ; No. 5, p. 349). — In this paper the author deals with 

 the Distribution and extent of the Marshes, their Geological origin, their 

 mode of formation, of reclaiming soil, &c. : but " no attempt has been 

 made to prepare a flora of the Marshes." He, however, gives a brief 

 classification (p. 349) with Halophytic or the wild salt-marsh formation, 

 of Spartina stricta, or ' Sedge association,' Salicornia-Suceda, or 

 Samphire, &c, and Statice- Spartina jnncea, or Fox-grass, &c. Secondly, 

 Mesophytic or Beclaimed salt-marsh formation (i.e. Meadow formation). 

 Thirdly, Hydrophytic, including Wet-marsh, Bog, Water-margin, and 

 Swamp formation. — G. H. 



San Jose Scale. By C. L. Marlett (Yearbook U.S. Dep. Agr. 

 1902, p. 155). — This well-known pest, so called from the place in Cali- 

 fornia where it was first discovered, has become prevalent in America in 

 the last thirty years, and is most destructive to Apples and Pears and other 

 deciduous fruits. If unchecked it ruins the tree in two or three years, but 

 may be kept in check by spraying the tree with lime-sulphur-salt. Most 

 European States, England excepted, have prohibited the introduction of 

 American fruit except under strict regulations, but the restrictions have 

 proved unavailing or unnecessary. The alarm first caused by it in 

 America is subsiding, owing to the efficacy of the 1 California wash ' for 

 spraying the affected trees. 



This scale is now well known in Japan, where it is a recent introduc- 

 tion. Exhaustive investigations, however, prove that the San Jose Scale 

 is indigenous, not to America, but to China, from which it was introduced 

 by plants brought to California about thirty years ago. The scale is kept 

 in check in Asia by a natural enemy, the Chinese lady-bird (Chilocorus 

 similis) which feeds upon it. Experiments are being made by the 

 introduction of the insect into America, but it is too early to speak of 

 results. The history and spread of the pest are minutely described, with 

 illustrations. — C. W. D. 



Saxifraga, Early-flowering- Species. By A. Purpus (Die Gart. 

 p. 433, June 13, 1903). — An illustrated article describing all the best 

 early spring-flowering Saxifragas. S. Burseriana, from the Dolomites, is
