Coleosporium ribicola, Aecial Stage of. By W. H. Long {Mycologia, viii. 
No. 6, p. 309, Nov. 1 91 6). — A Peridermium was found on needles of Pinus 
edulis in New Mexico. Spores inoculated on Ribes leptanthum produced the 
typical Coleosporium ribicola. Spores from this produced the same on R. longi- 
folium. In addition to these, the fungus has been found on R. Grossularia, R. 
inebrians, R. pumilum, R. Purpusii, R. valicola, and R. mescalerium. — F. J. C. 
Cranberries, End Rot of. By C. L. Shear {Jour. Agr. Res. vol. xi. No. 2, 
pp. 35-41; 1 plate). — The author states that the end rot disease of the Cranberry 
{Oxy coccus macrocarpus) is caused by a fungus hitherto not described. It is found 
throughout the United States, and attacked particularly the variety ' Late Howe.' 
The disease may start at the blossom or stem end of the berry, and causes complete 
decay of the fruit. In culture media only the pycnidia have been obtained. A 
characteristic series of colours in the mycelium and pycnidia are formed when 
grown upon stems of Melilotus alba in culture conditions. Spraying with 
Bordeaux mixture usually effectively controls this disease. The author has given 
the name Fusicoccum putrefaciens n.sp. to this fungus. — A. B. 
Cranberry, False Blossom of. By C. L. Shear {U.S.A. Dep. Agr., Bull. 444, 
pp. 8; 4 plates). — A malformation of the flower of the Cranberry causes con- 
siderable losses in Wisconsin plantations and elsewhere. No cause can be 
assigned save a lack of nutritive balance; better cultivation offers the only 
remedy. — E. A. Bd. 
Cranberry Rootworm. By H. B. Scammell [U.S.A. Dep. Agr., Bull. 263, 
pp. 8; 2 plates). — Rhabdopterus picipes does much damage in New Jersey to 
Cranberry bushes by feeding on the roots of the plants. Remedial measures 
have not bsen discovered, but invigorating the plants by sand and fertilizers 
is recommended. — E. A. Bd. 
Crocus chrysanthus, Warley Variety. By G. A. Bowles {Gard. p. 100, 
March 24, 1917). — Crocus chrysanthus is the most variable in colour of the species. 
It was first known in its plain rich yellow form. Maw found (i) forms with 
bronzed or feathered outer segments, golden within, which he named ; (ii) white 
forms with golden throat (var. albidus) ; (iii) white flowers outwardly suffused 
with lilac (var. caerulescens). The author had raised several generations of the 
latter, some of which appeared to be reverting to the yellow type when he received 
some bulbs from Hoogof Haarlem. These proved to C. chrysanthus, and it was 
thought some of its seedlings might give yellow forms, which proved to be the 
case at Haarlem. The flowers from the bulbs were shown by Miss Willmot, 
February 14, 1905, and received an A.M. under the name Warley variety. 
They are soft creamy yellow with rich orange throat and scarlet stigmata, and 
flower in February. — H. R. D. 
Currants, A Revision of the Red. By E. A. Bunyard {Gard. Chron. Nov. 24, 
Dec. 1, 8, and 1 5, with 9 figs.). — Shows there are five main groups descended from 
three distinct species. Ribes vulgar e, with distinct fleshy ring around pistil. 
R. rubrum, with no fleshy ring. R. petraeum, with claret-red flowers and red 
shoots. 
The groups are arranged thus : — 
I. Raby Castle Group. — Soft downy leaves, derived from R. rubrum pubescens. 
II. Versailles Group. — Short stems easily broken. Descendants of a large 
form of R. vulgar e known as macrocarpum. 
III. Goudouin Group. — Stout wood, coriaceous leaves, red flowers, form of 
R. petraeum. 
IV. Scotch Group. — Stiff upward folding foliage. Bell-shaped flowers 
tinged with red. Show descent from R. rubrum. 
V. Dutch Group. — Large light-green leaves. Flower of vulgare type.

Cyclamen Mite. By G. F. Moznette {Jour. Agr. Res. x. pp. 373-390 ; Aug. 
191 7 ; figs.). — Tarsonemus pallidus, a species allied to the Begonia mite of our 
own greenhouses, has done great damage to Cyclamen in America. It also attacks 
Chrysanthemums and Antirrhinums. The attack is generally upon leaves just 
unfolding, causing distortion and frequently thickening in the portions 
adjacent to the damaged areas. Flower buds are also attacked, and discolora- 
tion of the flowers follows. Blotching and streaking of the flowers and their 
rapid death are the common symptoms in this part of the plant. The mites, 
which are very small, difficult to discover, and hide in parts of the plant away 
from the light, are described and figured. Various methods of control have
