maximis^ oblongo-lanceolatis, marguie dentibus majubculis 

 distantibus quasi ciliatis. PetioUs canaliculalis glabris. 



Floribus maximis, ochroleucis, aut pallide sulphureisj 

 nutantibus in pedunculis longioribus foliis, filiforinibus, 

 apice longissime stipulatis, stipulis linearibus aeominatis. 

 JPetalis magnis, limbo rotundatfs, basi attenuatis. Binis la- 

 teralibus barba concolore profuse tectis, ceteris nudis; in- 

 fimo striisnigris picto. Cornu posiice longiuscule produc- 

 to, obtuso. Calycis laciniis longissimis angustis, acumina- 

 tis, margine ciliato. Stigmate recurvo subpubesc. 



Capsulis glabris. Radice tenuiuscula. 



This is by far the largest flowered species of the family. 

 The stem rises in spreading tufts to a considerable height, 

 generally in a half bent way. It flowers in abundance be- 

 fore the leaves are fully expanded, and is highly remarka** 

 ble for the unusual ochre-color of its fine flowers. I have 

 met with it in borders of ponds and meadows in April and 

 along Dan river, towards the Saura mountains, attached to 

 rich soil. The nest, is the only species with which it is 

 nearly allied — but can readily be distinguished by its size, 

 erect habit, and very differently shaped stipules- 



19. Species. V. repens Nobis. 



If observed by others, it has been comprehended among 

 the former in such a manner, as to render it impossible to 

 point out references.
