dance in fields northeast of the former, covering many square 
rods. Also occurs northeast of the Montowese barren area. 
Cracca Virginiana L. (Tephrosia Virginiana.) Like Lupinus 
perennis, this plant does not belong strictly within the limits 
of our area, but grows in great abundance just south and west 
_ of the Montowese plain. It is also common north of the area 
studied at North Haven and is a very important plant for such 
regions. 
Robinia Pseudacacia L. Common at North Haven where there 
are several medium-sized trees. 
Metbomia Dillenii (Darl.) Kuntze. (Desmodium Dillenii.)  Fre- 
quent. Grows near railroad at North Haven. 
Metbomia Canadensis (L.) Kuntze. (Desmodium Canadense.) 
Common, both at North Haven and at Montowese. 
Lespedeza capitata Michx. Common on both areas. 
Strophostyles helvola (L.) Britton. (S. angulosa.) Common at 
both places along the railroad tracks. 
Euphorbia polygonifolia L. Occasional at Montowese near river. 
Rhus radicans 1. Common in both places forming dense, low, 
foliage masses and covering the ground around the bases of 
trees. An important xerophyte.

Khus hirta (L.) Sudw. (R. typhina.) Occurs at Montowese near 
the railroad. 
Rhus copallina .. Frequent both at North Haven and at Mon-

Celastrus scandens LL. Common both at North Haven and at 
Montowese, occurring usually in groups of trees or plants. 
Sarothra gentianoides L. (Hypericum nudicaule.) Abundant at 
North Haven, where it formed a carpet over several large areas 
of sand during midsummer (see f/. 25, @). Much more 
abundant in 1902 than in 1901, probably on account of mois- 
ture, 
Helianthemum majus (L.) B.S.P. Common on the sand at both 
places, fruiting heavily. 
Viola sagittata Ait. and Viola pedata L. Frequent, both at Mon- 
towese and at North Haven, the roots being buried deep in 
the sand in many cases.
