148 PENTANDRIA. MONOGYNIA. 



est cucullatr, the 3 lower and sometimes the 2 upper 

 pubescent, segnntnts of" the calix g-labrous, lanceolate, 

 acute; stij^rna rostrate, depressed horizontally, distinctly 

 margined around. Flowers of a fine deep blue. — In the 

 sar.dy fields of New Jersey near Philadelplua, and also on 

 the banks of t'le Schuyltill. In hundreds of living plants 

 presenting- i}-^ same characters. The V. dentuta of Mr. 

 Fursh appears also a mere variety of V. sagittata. 



4. ovata* Leaves ovate, subcordate, crenate, rather 

 acute, often laceiately toothed at the base, equally and 

 for the most part conspicuously pubescent on either side, 

 petiole marginated; scape shorter than the leaves; seg- 

 ments of the calix subciliate; petals obovate, the two 

 lateral opes bearded. — V.prlmiilifoUa, of Pursh, notof Lin- 

 nxu3. On dry hilis, as correctly remarked by Mr. Pursh. 

 Flowers bright blue, flowering in April and May. Abun- 

 dant near Philadelphia on the shelving rocks which bor- 

 der on the Schuylkill and also in the sandy fields of New 

 Jersey. 



5. ciccullata. Smooth, leaves reniform-cordate, acute, 

 sinuously serrate, cucuUate at the base; peduncle often 

 as long as the leaf; lateral petals bearded. 



6. viUosa. Walter and Elliott. (V. sovoria. Willd. Hort. 

 Berol. 1. 1. 72.) Leaves roundish-cordate, crenate-serrate, 

 obtuse, upper side almost hirsutely pubescent, under side 

 smooth, peduncle about the length of the flowering leaves, 

 petals oblong, the lateral and lowest one bearded. — Leaves 

 rather thick, mostly incumbent on the ground, often pur- 

 plish on the under side. /3. * cordifolia- Leaves small, 

 cordate, acute, crenately serrate, flat with a very small 

 sinus, hirsutely pubescent above, smooth beneath; scape 

 always longer than the flowering leaves, segments of the 

 calix smooth, short, rather obtuse, scarcely produced at 

 the base; pe als short, obovate, — the 2 lateral and the 

 lower thinly bearded, multistriate.— Leaves thickish, al- 

 most of an equal length and breadth, elegantly cordate 

 and subacute, mostly incumbent on the ground, about an 

 inch long, and equally broad; stipules minute, subulate; 

 segments of the calix short and narrow, somewhat oblong; 

 petals rosaceous blue; capsule smooth, stigma small, ros- 

 trate and depressed, not margined all round. About 3 

 or four inches high; growing in dry woods on the banks 

 of the Schuylkill near Philadelphia. Flowering in May. 

 My friend Z. Collins, has long known this plant and con- 

 sidered it as a distinct species; it appears, however, 

 allied to V. villosa of Walter, and is decidedly the V. 

 sorotia figured in the IJortus Berolinensis, although the 

 leaf is said to bo pubescent beneath instead of above.
