108 Thirty-eighth Keport on the State Museum. 



and in Canadice, Ontario county, it was found by Mr. D. Byron Waite 

 growing on the " tops and sides of bare dry and sterile hills, and where 

 low shrubs and moss abound." 



Hydrangea arborescens, L. 

 Wellsburg, Chemung county. E. A. Burt. 



POTAMOGETON ROBBINSII, OdkeS. 



Hudson river near Rhinebeck. H. Andrews. The plants were sterile 

 as usual. 



Habenaria rotundifolia, Rich. 



Turin, Lewis county. July. R. B. Hough. This is the second locality 

 in the State for this rare plant. Mr. Hough informs me that it is difficult 

 to obtain perfect specimens of this plant, most of the flowers being 

 injured, apparently by some insect. 



Trillium grandiflorum, Salisb. v. variegatum. 



This interesting variety or form has the leaves petiolate and the petals 

 variegated with green, which is usually in the form of abroad longi- 

 tudinal stripe through the middle. It was discovered in dense woods 

 near Jamesville, Onondaga county, by members of the Syracuse Botan- 

 ical Club, and specimens were contributed to the Herbarium by Mrs. 

 L. L. Goodrich and Mrs. S. M. Rust. It has also been found on 

 Goat Island by Hon. G. W. Clinton. In the Jamesville locality it was 

 associated with Trillium erectum and typical T. grandiflorum. In one 

 specimen communicated by Mrs. Goodrich the petioles originate near 

 the ground, the stem being very short. They are about three and a half 

 inches long and the peduncle is five inches long. In other specimens 

 these parts are less elongated and the form appears to be merged into 

 the type. The specimens indicate a coincidence between the petioles, 

 peduncles and green color of the petals. Generally the longer petioles 

 are accompanied by^ longer peduncles and broader green stripes on the 

 petals. This coincidence between form and color is remarkable. 



JUNCUS TRIFIDUS, L. 



Sam's Point, Shawangunk mountains. Prof. N. L. Britton. Probably 

 this is the most southern station for this Juncus in our State. It occurs 

 at Lake Mohunk and also on the high summits of the Adirondack 

 mountains. 



SCIRPUS POLYPHYLLUS, Vdhl. 



Catskill. G. W. Clinton. A rare species in our State. 



SCIRPUS SYLVATICUS, L. 



Wet places about half a mile south-east of Loudonville. 



Glyceria fluitans, L. 

 Caroga lake. The form with long flat linear floating leaves, suggestive 

 of the specific name, is not rare in the lakes of the Adirondack region, 

 but it is not always fertile. 



Aira CjESPITOSA, L. 

 Wet ground. Caroga. It was growing in company with A. fiexuosa 

 which usually inhabits dry, rocky, sterile hills.
