REPORT OF THE STATE BOTANIST IQII 43 



station for it at Orient Point where he collected fine specimens 

 of it, some of which he has kindly contributed to the State 

 herbarium. 



Trichostema dichotomum L. 

 Orient Point. September. R. Latham. The flowers of this 

 plant are generally blue. From this the common name blue curls 

 is evidently derived. The plants sent by Mr Latham have pink 

 flowers. 



Ustilago osmundae Pk. 



Fresh specimens of this singular and imperfectly understood 

 parasitic fungus were collected on the royal fern, O s m u n d a 

 r e g a li s L., by S. H. Burnham, in Cambridge, Washington co., in 

 June. An examination of them revealed a feature previously over- 

 looked. In the early stage of the fungus the cell, which eventually 

 becomes two spores, is single. Soon it develops into a pair of glo- 

 bose echinulate reddish brown spores, 12-16 /* in diameter, these 

 finally separate and with others form a dusty layer of spores over 

 the surface of the young pinnae on which they develop. In develop- 

 ing its spores in pairs this species is unlike the genus Ustilago and 

 is therefore referred to the genus Mycosyrinx and takes the name 

 Mycosyrinx osmundae Pk. 



Mycosyrinx osmundae cinnamomeae n. var. 

 This dififers from the typical form in the paler brown color of 

 the spore mass and the even surface of the spores. It occurs on 

 the base of the pinnae of the cinnamon fern, Osmunda cinna- 

 m o m e a L. It is very rare. Only two small specimens were 

 found. Cambridge. June. S. H. Burnham. 



Vaccinium oxycoccus L. 



This cranberry is common to Bonaparte swamp. Cranberry 

 marsh, Averyville marsh and Peacock marsh. It is found in nearly 

 all our sphagnum marshes and on the open mossy summits of most 

 of the high mountains of the Adirondacks. It is a very hardy species 

 and can maintain itself where the larger and cultivated species, 

 Vaccinium macrocarpon Ait, can not. It is there- 

 fore available for cultivation where the other would be a failure. 

 For the purpose of exhibiting the peculiar flora of Peacock marsh a 

 list of its plants is here given. This list was made June 15, 191 1.
