Orchids and their commensal fungi : Evolution in Symbiosis. 



By N. Bernard {Ann. Soc. Nat.,\o\. ix., No. 1, pp. 1-64; 12 figs.).— In 

 the majority of orchids, symbiosis is intermittent in the adult state, but is 

 absolutely necessary for germination. In the more perfect degrees of 

 symbiosis illustrated among orchids, e.g., Neottia Nidus-avis, not only 

 will the seeds refuse to germinate in the absence of the fungus, but the 

 orchid cannot live without its symbiotic fungus. 



Rhizoctonia repens, R. mucoroides, and R. lanuginosa were obtained 

 from the roots of orchids. — S. E. W.
