Report of the Committee on ^ear Slight. 295 



Dicksonia Antartiea. Cjathea Medullaris. 



** Squarrosa. " Princeps. 



" Arboresceus, rather rare and noble. Cibotium Regale. 



Alsophila Australis. *< Spectabile. 



'• Excelsa. " Schiedei. 



" Contammans. 



And enormous plants of Platycerium alcicorne, seldom seen in such size and con- 

 dition. What the Dasylirion anotichum was like is seen in the wood cut. 



There were likewise very fine plants of Phorniium, one of P. tenax variegatum, 

 and of P. Colensoi variegatum, and noble specimens of Cycas revoluta, Latania 

 borbonica, Sabal unibraculifera and other palms. The beautiful Lasiandra macrantha 

 was well done, and quantities of an old-fashioned showy plant, the Dlplaciis^ not 

 puniceus, but glatinosus, made a fine display on the shelves. A charming old plant, 

 Plumbago capensis was also remarkably well flowered. The roof of the aquarium, 

 or Lily home, attached to the Conservatory, was well covered with climbers; prom- 

 inent among these was a very fine variety of Passiflora quadrangularis, this seemed 

 different and larger than the sort generally grown. 



Allamanda, Schottii and the Stephanotis were extremely well done in this house, 

 a good effect was produced by the little used and curious Aristolochia ornithocephali. 

 Bottle and Smoke Grourds were also seen to good effect on the roof in company with 

 the Souly green cucumber. In the tank were some plants of Nymphoea dentata, N. 

 Caridea and others, and a seedling of a beautiful and delicate pink, of the size of 

 dentata, said to be a seedling between N. dentata and N. rubra. Over the tank 

 various baskets of Stanhopes were pushing grand masses of flowers, and I got a new 

 idea of basket-furnishing, the bottom and side filled with Epiphyllum crowned with 

 a graceful plant of Adiantum sethiopicum. Among the Palms, were tastefully 

 arranged a fine plant of the very rare Slifftia chrysantha, and last and best of all, 

 probably, for health and size, a noble specimen of Pandanus utilis. Among the 

 orchids and dendrobinus was D. Speciosum, a hardy New Holland Orchid, very 

 useful for winter flowering. 



Moranta, Caladium, Dracaena, were well represented, and the collection of Mexican 

 and other Ferns, was rich and extensive. Among the latter, P. Andromedifolium, 

 an exquisite California Fern. Here, too, I met with the little grown Aspidium, 

 fragrans, whose fronds are as sweet as if perfumed with the essence of violets. 



Report of tlie Committee on Pear Blight, its Canse? 

 Kem.edy or Preventive. 



ON. MARSHALL P. WILDER, President American Poraological Society:— 

 Dear Sir — The Committee appointed at the last annual meeting of this Society, 

 to investigate the cause of pear blight, and, if possible, recommend a remedy or 

 preventive therefor, beg leave to submit as follows : 



The task allotted to"your committee is connected with unusual difficulties, as the 

 subject is one that has for more than a quarter of a century remained an unsolved 

 problem. We therefore entered upon the performance of our duties with the convic- 

 tion that our efforts must fall short of doing justice to the object in view.
