208 The Ottawa Naturalist. ' [Feb. 



Criddle, both from the artistic and botanical point of view, 

 deserve much praise. 



3. One collection of economic seeds and weed seeds, put up 

 by the Seed Branch, Department of Agriculture, containing the 

 seeds of the most common forage plants and weeds. 



4. One pocket collection, containing seeds of the worst 

 weeds of the country, all mentioned in the Seed Control Act, 1905. 



Several cases containing insects of many kinds were exhibited 

 by Mr. Arthur Gibson, Mr. C. H. Young, and Mr. J. W. Baldwin. 

 Those brought by Mr. Gibson were from the collection of the 

 Division of Entomology at the Central Experimental Farm. 

 They represented a collection mostly of local butterflies and 

 hymenopterous insects. Mr. Young's cases contained chiefly 

 a collection of microlepidoptera taken in the Ottawa District. 

 These were beautifullv mounted and were much admired. 

 Mr. Baldwin's specimens were in two oases, one of which con- 

 tained 92 specimens, representing 60 species of moths collected 

 at Ottawa. In this case were some rare forms. In the other case 

 an interesting series of the genus Catocala was shown. Dr. C. 

 Gordon Hewitt sent in a small but interesting exhibit of 

 coleoptera and diptera fossilized in gum anime, obtained for 

 commercial purposes from Zanzibar, from areas where no trees 

 are now visible. The gum is the product of Trachylobiiim 

 hornemannianum . 



Mr. Young also showed some cases containing a valuable 

 collection of specially well prepared star fishes and crabs, all of 

 which had been collected by him in British Columbia during the 

 past 3^ear. 



Mr. H. Groh, Assistant Botanist, Experiinental Farm, 

 exhibited a number of botanical sheets r^ native parasitic flower- 

 ing plants which are destitute of greci. foliage. The following 

 are some of those which were noticed. 



CuscutaEpithymum, Clover dodder; CuscutaGronovit, Love- 

 vine; Monotropa unifora, Indian Pipe; Monoiropa Hypopitys, 

 Pine-sap ; Pterospora andromedea. Pine-drops ; Epijagus virginiana, 

 Beech-drops; Conopholis americana, Squaw-root; Orohanche 

 uni flora, One-flowered Cancer- root ; Orobanchp jasciculata. Broom- 

 rape. 



Mr. Groh also showed a stem of Juueberry (Amclanchier), 

 which, according to him, "had been virtually choked to death 

 by a vine of Climbing Bitter-sweet (Celastrus scandens). The 

 stem had continued to increase in diameter until the coils of 

 the vine were almost buried in the wood, but finally last June 

 the obstruction of the passage of food had become so serious that 

 the leaves turned yellow and dropped."
