V. acauHs. Foliis prlmariis rarJs lanceolato-cordatis, 

 breviter petiolatisj exterioribus, crenato-dentatis- (saepe 

 omnino carent.) Secundariis longe peliolatis, frequentiori- 

 bus, longis, oblongis, vix acurainatis, margine serratis, basi 

 cordato-sagittatiSj incisis, i. e. dentibus elongatis, majuscu- 

 lis distantibus munitis, ceterum glabriusculis, aut pag. supe- 

 riori pubescentibus. Petiolis plerumque folia longitudine 

 excedentibus, semiteretibuSj piiosiusculis. Stipulis radica- 

 libus longissjmis, glabris, lineari-acuminatis. 



Floribus inversis, mediocribus, purpureo-coeruleis, in 

 scapis longis. Fetalis oblongo-ovatis, intus albescentibus, 

 omnibus albo-barbatis, excepto inferlori nudo ; omnibus 

 eleganter purpureo-venosis. Cornu obtuse, postice produc- 

 to. Calycis laciniis glabris, marginatisj lanceolatis, acumi- 

 natis. Stigmate rostrato, depresso, marginato. 



Scopes filiformibus, subquadratis, folia interdum exceden- 

 tibus* Stipulis alternis, minutis, distantibus, infra medium 

 sitjs. 



Capsulis glabris, stylo coronatis. 



Radice corallina brevi incrassata; caespites sparsas ef-

y var. dentata Pursch p. 172. n. 5. foliis basi truncatis. 



This species, although certainly heterophyllous, is so well i 



distinguished by the long-petiolated, oblong, hastately den- . \ 

 tate leaves, that it is not likely to be mistaken. I coincide 

 with Mr, Nuttall in regarding his emarginata and the denta- 

 ta of Pursch as varieties. I have met with both here rare- 

 ly. Indeed the sagittata itself occurs but rarely with us. 

 Elegant specimens have been found at Chapel-Hill by Pro- 

 fessor Mitchell. It appears to be more common towards j 

 the north and flowers with us, end of April. In the variety 

 emarginata the scape is often a foot long and exceeds the 

 length of the leaves, notwithstanding these are uncommon- 

 ly long-petiolate. The color of the leaves is remarkably 

 blueish green as in V, primulaefolia.
