1924) PALMER. THE LIGNEOUS FLORA OF RICH MOUNTAIN 1£5 



Rubus occidentalis L. The wild Raspberry grows in thickets and on 

 rocky ledges on the north side of the mountain. 



Rubus flagillaris var. invisus Bailey. This Dewberry is common in 

 rocky ground, both in the valley and on the mountain slopes. 



Rubus frondosus Bigel. Found in thickets in the valley and on the north 

 side of the mountain. 



Rubus Andrewsianus Blanchard. This Blackberry, with upright or 

 slightly arched stout canes, is very abundant in thickets in the valley 

 and on the tableland at the top of Rich Mountain. 



There is evidence of at least two other species of Rubus in this locality, 

 one of them resembling Rubus canadensis L , and perhaps referable to that 

 species, but with the incomplete material available I am unable to identify 

 them definitely. 



Rosa setigera var. tomentosa Torr. & Gray. Found in thickets and open 

 places in the valley, but not common. 



Rosa subserrulata Rydb. This little Rose is common throughout much 

 of the Ozark region. In this locality it is sometimes found in the valley, 

 but is much more common on the rocky mountain sides and on top, where 

 it sometimes grows in patches covering many square meters. The plants 

 are usually low, often not more than two or three decimeters in height, 

 although in protected situations they are sometimes nearly a meter tall. 

 With its hispid prickly stems, sharply serrate leaves and somewhat glandu- 

 lar foliage and inflorescence, it is an easily recognizable and well marked 



species. 



LEGUMINOSAE 



Gleditsia triacanthos L. The Honey-locust is sometimes found in the 

 valley, but it is not common. 



Cercis canadensis L. The Redbud is a common small tree found in the 

 valley and on top of the mountains, and less frequently in open places 



on the rocky slopes. 



Robinia Pseudoacacia L. The Black Locust is a common species on 

 the rocky slopes of the mountains on both sides of the valley, and it 

 sometimes descends to the rocky creek banks. It is undoubtedly native 

 on these mountains and through much of the southern Ozark region. 



Amorpha fruticosa L. This shrub was noted only along the margins of 

 Big Creek and its tributaries in the valley. 



Amorpha tennessensis Shuttlw. This species, which closely resembles 

 the last, grows in similar situations. 



Amorpha glabra Desf. Sometimes found in the rocky valley, but much 



more common in glades and open rocky places on the south slopes of 



Blackfork Mountain. It is a tree-like shrub, sometimes more than two 



meters tall. 



RUTACEAE 



Ptelea trifoliata L. Found in rocky thickets in the valley, but moat 

 abundant on the mountain tops.
