1^6 THE PLANT WORLD. 



This region not only contains grasses which occur elsewhere in 

 the State, like Asprclla Jiystrix, Cimia arundinacea^ Poa pratensis, 

 Andropogon scopariits, Lccrsia Virginica and Lecrsia orysoides, but the 

 tops of open clay hills are covered with DantJionia spicata, and on one 

 or two of the clay ridges Panicmii filifonnc, small and diminutive in 

 most cases occus; Poa debilis^ first found by Barnes and Miller; Mulilen- 

 bergia sobolifcra and M. Wildcnovii are found in damp, shady woods. 

 The rocky talus supports Aspidiuiii Goldiajtiiiu, A. spinulosuni and 

 PJiegopteris polypodioides only in one place. These species will soon 

 disappear. Nearby is found Circcea alpina. The rich woods contain 

 Phegoptcris polypodioides in considerable quantity. Aspidiiini acrosti- 

 cJioidcs in damp rich woods. Lycopodiiini lucidiihiin and L. couiplanatuni 

 have both been found by Mr. Reppert on the sandstone talus One 

 of the hillsides contains a considerable quantity of Gaylussacia resinosa; 

 it occurs with DantJionia spicata and Panicitm filifornic. Hieracium 

 scabriini ^xi^ H. Caiiadcnse occur with Danthonia ; both are rare in 

 Iowa. Lespcdcca reticulata and Goodyera pubescens are associated 

 with Gaylussacia. 



The arboreal vegetation is in no wise peculiar, except the occur- 

 rence of the White Pine {Pinns strobus). The locality given in Gray's 

 Manual (6th edition), near Davenport, is based on early specimens 

 collected by Dr. Parry, and most likely were from "Wild Cat Den." 

 We may also note the presence of Salix discolor and 5. cordata in low, 

 springy places ,• 5. Jiuniilis abounding over the open places in woods. 

 Oucrcus rubra, 0. alba, Acer nigrum, Cornus alternifolia, Ostrya Vir- 

 ginica, Carya alba and Fraxinus viridis abound in the region.

SCUTELLARIA PARVULA Michx. 

 By C. F. Saunders. 



ALONG the Schuylkill river, some thirty miles above Philadel- 

 phia, there is a station for this plant, where it grows in dry, 

 red shale at the summit of a rocky bluff which rises precipi- 

 tously 70 or 80 feet above the river level. It is a sun-burned, 

 exposed spot, answering almost exactly to the description of Dr. Hal- 

 sted's locality mentioned in the May issue of The Plant World. The 

 location seems to suit the little plant admirably, for, though not abun- 

 dant there, it grows to a height of five or six inches and looks thor- 

 oughly thrifty. That is the only locality for the species known to the 

 present writer.
