1165. Shrivastava, K. P. A preliminary note on the improvement of oranges. Agric. 

 Jour. India 15: 508-515. 6 fig. 1920. — A general discussion is given of pruning, irrigation, 

 and manuring. Experiments are being made with organic manures and mineral fertilizers. 

 There is a distinct improvement in the vegetation, growth, and fruiting of the trees resulting 

 from the use of nitrogenous manures. Mohwa {Bassia latifolia) refuse is producing best 

 results, followed by castor cake, cattle dung, and calcium nitrate. The mineral fertilizers 

 have as yet produced no noticeable effect. — /. /. Skinner,

FLORICULTURE AND ORNAMENTAL HORTICULTURE 



1169. Anonymous. A new Polygonum. Florists' Exchange 50: 1017. 1920. — P. cam- 

 panulatum attracted much attention and received an award of merit when recently shown in 

 London. It is a plant of bushy growth, 2J ft. high, with distinctly bell-like flowers, and 

 colored much like Kalmia latifolia. It is probably a plant of great promise, a possible acqu 

 sition for pot work. — L. A. Minns.

 known and seldom seen. The list includes, of hardy herbaceous kinds, E. perfoliatum, 

 E. agertoides, and E. Fraseri, all white, and E. coelestinum, one of the best blue perennials; 

 while for growing under glass there are E. Purpusi, sweetscented, pink, and E. conspicuum, 

 shrub-like, a good winter bloomer and summer bedder. — L. A. Minns.
