distally brownish. Flowering in May or June. 



Thickets and along streams, widely distributed through the 

 Rocky Mountain plateau, eastward passing into S. leporella Bickn. 

 In our area seen only as collected by Edward Palmer 218 at some 

 point in Oklahoma, probably "on the False Washita, between 

 Fort Cobb and Fort Arbuckle" in 1868.

2. Scrophularia marilandica L. 



Scrophularia marilandica L., Sp. PI. 619. 1753. "Habitat in Virginia." 

 Based upon a plant grown in the Upsala Garden, which from the descrip- 

 tion in the Hortus Upsalensis 177. 1748, would appear to have been the 

 species here considered. 



(?) Sa'ophularia hastata Raf., Fl. Ludov. 44. 1817. Based upon a fuller 

 description in Robin, Voy. Louisiane 3: 39.5. 1807. Description of 

 leaves 'soft to touch' appears to describe forma neglecta (below), but the 

 leaves in this species can scarcely be called hastate. The carefully 

 described flower however would appear to be of this genus, although no 

 mention is made of the rudimentary fifth stamen, nor is the corolla ever 

 pubescent within (veloutee). 



Scrophularia neglecta Rvdb.; Small, Fl. S. E. Un. St. 1058, 1337. 1903. 

 "Type, Riley Co., Ivans., Norton, no. 779 in Herb. N. Y. B. G." Type 

 seen in Herb. New York Botanical Garden. This plant differs from what 

 is considered true S. marilandica only in the presence of pubescence on 

 the lower surface of the leaves, a condition found in the northern and 

 predominating in the western part of the range of the species. Eastward 

 this sporadic and fluctuating state can be only considered as a forma, 

 neglecta (Rydb.) Pennell, comb, nov; the two should be studied. 



Corolla externally greenish-brown, duller, within purple-brown 

 distally. Flowering in September and October. 



Open woodland, in central and northwestern Arkansas; and in 

 southern Louisiana; certainly more generally distributed in our area. 

 In our area only forma neglecta has been seen. A wide-spread 

 eastern species, ranging from Massachusetts to Ontario and Neb- 

 braska, south to Georgia and Louisiana.
