kxii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



purpose showed that a large proportion of the nitrogen supplied 

 in the manure was washed out of the soil by the rainfall, 

 as a consequence of which the analysis of the grain showed but a 

 small quantity of nitrogen in proportion to the quantity applied in 

 the manure. 



Unhealthy Condition of Plants.— A letter was read from Mr. 

 Tonks, detailing the ill-success which had befallen him in cultivating 

 various plants where formerly he was very successful. The letter 

 conveyed no hint as to the cause of the misfortune, which probably 

 could only be discovered on the spot. 



Parasite on Sempervivum.^M.T. W. G. Smith alluded to a para- 

 sitic fungus, Endophyllum sempervivi— a rare plant, but which when 

 introduced into the greenhouse had proved very destructive to 

 species of Sempervivum. 



Gall on Eucalyptus.— Dr. Masters showed a remarkable fusiform 

 gall on a species of Eucalyptus, and which had been sent to him by 

 Baron von Mueller. It was referred to Mr. MacLachlan for report. 



Plants Exhibited. — Rev. H. Earpur-Crewe showed Tulipa Or- 

 phanidesi, Iritillaria Ehrharti from Syra with a small bell-shaped 

 purplish flower edged with green ; various species of Muscari, as 

 yet unnamed ; and a white variety of Scilla italica. Messrs. Veiteh 

 showed the elegant Chionographis japonica, introduced from Japan 

 by Mr. Maries. It is a perennial, of tufted habit, with oblong- 

 obovate, acute, wavy-margined, glabrous leaves, and an erect flower- 

 stalk 12—18 inches high, with scattered lanceolate bracts, and 

 terminating in a linear spike of sessile white flowers, each flower 

 with six linear narrow white segments. Anthurium Scherzerianum 

 pygma3um, also from Messrs. Veitch, was shown. Its very narrow 

 leaves and spathe, and its spadix stalked above the spathe, were 

 points, irrespective of size, in which it differed from the ordinary 

 form, and which secured for it the award of a Botanical Certificate. 

 Another Anthurium was shown, a cross between the ordinary 

 A. Scherzerianum and the white variety; in this case the 

 spathe was spotted with small red spots on a white ground. 

 A curiously twisted variety of Cryptomeria japonica was also 

 shown; the variety is figured in Siebold and Zuccarini's Flora 

 Japonica.
