Echeveria metallica {Ber. Ilort. Beige, June 1901). — Referrinfr 

 to the article on vegetative multiplication, c/. Bachyphytum, a writer 

 describes how seed of Echeveria can easily be obtained, and suggests a 

 similar trial with that plant. — Cr. H.

Eelworm Disease of the Chrysanthemum indicum. By 



Paul Sorauer {Garteiiflora, p. 85; 15/1/1901). — Details cha- 

 racteristics of the disease. These nematoid worms, which Professor 

 Ritzema Boss, Amsterdam, has identified with tlie Aj)Ju'lcucJit(s olcsistus, 

 appear to bear a certain resemblance to the Trechina which attacks man. 

 These nematoids do not appear in the cells of the leaves attacked, but in 

 the intercellular spaces, generally not far from the surface. Like the 

 Chrysanthemum Rust, the ravages of this disease have appeared suddenly 

 at various places. In the "Journal of Plant Diseases," by Boss, it is 

 recorded that the same worm attacks Begonias and various Ferns, 

 especially Btcris cretica, Aspleniuiii hulbiferuiu, and A. diversifoliuin. 

 The worm is probably introduced from the soil. Dr. Osterwalder found 

 this to be the case with Gloxinias and Aucubas. Damp and sour soil 

 seemed to induce the presence of these nematoids. — C. E. S. 



Eel- worms on Cultivated Plants, (a) By Th. Cattie (Wageningen) 

 and {b) by J. Hofer (Ziirich) {Zeit. f. Bflanz. bd. xi. ht. 1, p.' 34 ; 

 March 1901.) — Two short papers on diseases of pot-plants caused by eel- 

 worms or nematodes. The following are mentioned : — Pteris Omrardi 

 var. cristata, varieties of Bteris cretica, and Asplenium showed dark 

 discoloured patches on the leaves, and the plants died later. Chrysanthe- 

 mums were attacked by a leaf disease in October and November ; irregular 

 spots appeared and the leaves fell off". Coleus and Salvia also showed 

 leaf-spot. A similar disease is known on Begonia leaves. In all cases 

 eel-worms were found in the diseased places, their identification being 

 confirmed by Prof. J. Ritzema Bos as species of Aphelenclius. — W. G. 



Elaeag'nus umbellata, Himalayas, China, and Japan. By E. Andre 

 {Bev. Hort. p. 85 ; fig. 26 ; January 1901).— Strongly recommended 

 as an ornamental hardy shrub ; red persistent berries through winter, 

 fine effect.— C. T, D. 



Epi-Cattleya x Orpetiana. By Oakes Ames {Amer. Gard, xxii. 

 828, p. 251). — A new bigeneric hybrid of the second generation, raised 

 by Mr. E. 0. Orpet, of South Lancaster, Mass., out of Cattlcya amethysto- 

 (jlossa, by Epidendrum x 0' Brienianum. Like other hybrids of its 

 class, the Epidendrum parent is pre-potent, and the pollen masses are 

 more or less abortive. — C. C. H.
