 Family 89. Anacardiace^. Sumac Family 



488. dwarf black OR MOUNTAIN SUMAC 



KHUS COPALLINA L. 



Occasional, in clumps in open places. One clump on Long 

 Point, about a quarter of a mile from the tip of the point, and 

 another along- the road near Farrar's. One of the earliest shrubs 

 to take on autumn coloration, the dark shining leaves becoming a 

 rich cherry red, brighter than the other sumacs. The highest 

 panicles are mostly staminate ; the more perfect flowers are on the 

 lower panicles. 



489. STAGHORN SUMAC 



RHUS HIUTA (L.) Sudw. 



Common, in clumps in dry places. One clump by Overmyer's; 

 more common on the east side of the lake ; one clump at the corner 

 of Culver's, along the road, another back in the edge of the woods, 

 a third clump along the road on the east side. These latter are of 

 unusual size, almost trees. The fruit bearing panicles retain 

 the fruit several seasons, apparently until it actually weathers off 

 from the parent plant. Some plants noted were defoliated by 

 insects. 



490. SMOOTH UPLAND OR SCARLET SUMAC 



RHUS GLABRA L. 



Occasional in clumps in hilly places, scattered all about the lake. 

 A large clump by Overmyer's field, and along the road through the 

 woods from that place, another patch on the lake shore between 

 Green's and Murray's, and another north of the ice-houses. A 

 handsome bush, one of the first shrubs of the season to assume au- 

 tumn tints, the lower leaves often flaming red by August. The 

 seeds are scattered by birds, and colonies often become established 

 along fence-rows and ditches, where it spreads by root, and being 

 difficult to eradicate, becomes a great nuisance. 



491. GREENE'S SUMAC 



RHUS ARBUSCULA Greene 



A low dwarf form, somewhat resembling Rhus glabra, makes a 

 small clump in Green's woods near Lost Lake, just below the 

 Bardsley cottage, this being the type locality, the type and a cotype 

 having been collected there in 1906. It is distinguished from R. 

 glabra by its smaller size, fewer and smaller and thinner leaflets 

 and smaller fruit. In the autumn of 1913 additional localities were
