788 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 



an underground fernery is devoted to them, and at Kew a small house 

 with glass cases. 



They may be divided into two classes, those with a creeping stem and 

 those without. The creeping plants like to spread over damp, cool sand- 

 stone or old tree ferns ; the others may be planted in chinks. The chief 

 points to be attended to in their culture are heavy shading and frequent 

 pouring of water among the rocks, not on the fronds, and cool treatment 

 in summer. — H. R. D. 



Ferns in Parks and Gardens. By W. Wiirth {Oestr. Gart. Zeit. 

 vol. V. pt. X. pp. 361-365; 4 figs.). — Barren corners of the garden 

 snould be planted with Aspidium Filix-mas and Athyriuni Filix-joemina. 

 Osmunda regalis, Onoclea Striithiopteris, Aspidhun Thelypteris, 

 Aspidium cristatum, and A. spinulosum like a damp situation, and soil 

 rich in humus. 



Polypodium, Phegopteris, P. Robertiamim , and P. Dryopteris grow 

 well among decaying trees and bushes. 



Pteridium Aquilinum flourishes in a light, sandy soil. Ceferach 

 officinanim, Asplenium Tricho^nanes , A. septentrionale (dislikes lime), 

 A. rutamuraria and A. AdiafnUim-nigrum thrive well in dry, sunny, 

 stony places. A. viride, Allosurus crispus, Scolopendrium officinale, 

 Blechnuvi spica7it, Polypodium viilgare, Aspidium Lonchitis, and 

 Asplenium aculeatiim var. lohatum prefer the shade of rocks. 



Woodsia ilvensis likes a sunny place among rocks, but dislikes lime. 

 Crystopteris fragilis, G. sudetica, and 0. montana like a moist, shady 

 position on rocks. 



Ophioglossum vulgatum grows in moist meadows, and Botrychium 

 Lnnaria is found on dry sunny slopes. — S. E. W . 



Fig*, A New Anthracnose of. By Stevens and Hall (Zeitschr. 

 f. Pflanze7il{.mnk. xix. 1909, Heft 2, p. 65 ; 1 plate).— Describes a new 

 disease of the fig in the eastern parts of North Carolina, the chief 

 characteristics of which are a rot and premature fall of the fruit. In 

 general character the rot resembles the " bitter-rot " of the apple. 

 A species of Colleiotrichum was found constantly associated with the 

 disease, which presented no difficulty as regards isolation in pure 

 culture. Infection experiments with pure cultures were carried out 

 both in the laboratory and in the field, and successful inoculations 

 were easily made when the atmospheric moisture was plentiful, but 

 only with difficulty in dry air. The disease occurs naturally only in 

 specially moist localities and on the sea-coast. The fungus isolated 

 does not agree in its characters with any previously described species of 

 Colletotrichum, and the authors therefore name it C. Carica, n. sp., and 

 append a specific description. — G. H. P. 



Flavouring- Extracts, The Manufacture of. By E. M. Chace 



(U.S.A. Dept. Agr. Year Booh, 1908; pp. 4; 4 plates).— An account
