148 PENTANDRJA. MONOGXNIA. 



est cucullate, the 3 lower and sometimes the 2 upper 

 pubescent, segments of the calix g-labrous, lanceolate, 

 acute; stigma rostrate, depressed horizontally, distinctly 

 Hiarg-ined around. Flowers of a fine deep blue.— In the 

 sandy fields of New Jersey near Philadelphia, and also on 

 the banks of the Schuylkill. In hundreds of living plants 

 presenting the same characters. The V. deJitata of Mr. 

 JPursh appears also a mere variety of V. sagitmta. 



4. QXHita* Leaves ovate, subcoidate, crenate, rather 

 acute, often lacei-ately toothed at the base, equally and 

 for tlie most part conspicuously pubescent on either side^ 

 petiole marginated; scape shorter than the leaves; seg- 

 ments af the calix subciliate; petals obovate, the two 

 lateral ones bearded. — V. primuii folia, of Pursh, notof Lin- 

 nxus. On dry hills, as correctly remarked bv Mr. Pursh. 

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

 dant near Pli'ladelphia on the shelving rocks which bor- 

 «ler on the Schuylkill and also in the sandy fields of New 

 .1 ersey. 



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

 sinuously serrate, cucullate at the base; peduncle often 

 as long as the leaf; lateral petals bearded. 



6. villosa. Walter and KUiott. {V. sororia. 'Wllld. Hort. 

 lierol. i. t. 72.) Leaves i-oundish-cordate, crenate-serrate, 

 obtuse, upper side almost hirsutely pubescent, under side 

 smooth, peduncle about the lengtli of the flowering leaves^ 

 petals oblong, the lateral and lowestone bearded. — Leaves 

 3-ather thick, mostly incumbent on the ground, often pur- 

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

 cordate, acute, ci'enately serrate, flat with a very small 

 t^inus, 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; petals sliort, obovate,— the 2 lateral and tiie 

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

 most of an equal length and breadth, elegantly cord^e 

 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 I'osaceous 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 xVIay. 

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

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

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

 8'jroria figured in the Hortus Berolinensis, although the 

 leaf is said to bs pubescent beneath instead of above.
