temloha the middle segment regularly divides in three, and the lateral 

 ones into two, while in V. brittoniana each segment divides into three. 

 There are, of course, some deviations, but these are the normal types of 

 leaf in the several species. In the pedata group, however, the central 

 lobe does not divide, while the lateral ones in typical leaves are four- 

 parted. Occasionally V. brittoniana comes very near to this type by 

 producing only one lateral lobe to the middle segment, and in one leaf 

 in my collection it is undivided. This denotes a tendency toward 

 the pedata type, which must be the extreme of development in this 

 direction. 



If this form is regarded as separable from the preceding it must 

 bear DeCandolle's name lineariloba, which has priority over Prof. 

 Greene's inornata. Both are based upon the same plate of Curtis' 

 Botanical Magazine.

Range. — From the lower mountains to the coast, through eastern 

 Pennsylvania and central and southern New Jersey (not plentiful in 

 the pine barrens) . 



Habitat. — Dry sandy or rocky banks and fields. 



Description. — Flowering plant. Media, Delaware county, Pennsyl- 

 vania, April 26, 1903. No. 5,145, Herb., W. S. Flowers 10-15 mm. 

 broad, purple (between "aster-purple" and "violet" of Ridgway) ; 

 petals white at the base, the lower one lined with darker; lateral 

 petals with conspicuous patch of beard, lower one slightly pubescent; 

 sepals lanceolate ; scape pubescent, 30 mm. long. Leaves ovate- 

 cordate, obscurely crenate, except at base, where teeth are more 

 conspicuous, 15 x 20-18 x 30 ; thick and very pubescent, especially 

 above; decurrent on the petiole, which is also densely pubescent, 

 12-18 mm. long. 



Later flowering specimens have leaves 28 x 45 mm., petioles 35 mm. 

 and scapes 60 mm. in length. 



Fruiting plant, Media, June 4, 1903. No. 5,146, Herb., W. S. Pu- 

 bescent all over; scapes 70 mm.; leaves 45 x 75 mm.; petioles 45-60 

 mm. ; cleistogenes erect, 45 mm. high. 



In some very dry exposed spots this species becomes quite stunted, 

 but flowers profusely. A root from Gladwyn, April 26, has leaves only 

 7 x 12 mm., petioles 5 mm., but bears seven flowers on scapes 35 mm.
