An account of 



Corydalis persica Cham, et Schlecht. 



with remarks on certain allied species of 



Corydalis Vent. 



By 



David PRAIIV 



With plate VI. 



Among those species of Ihe genus Ihat, for my own convenience, 

 I shall hère continue lo lerm Corydalis Vent. \ none are more diffîcull 

 lo differentiate satisfactorily tlian the ones thaï belong to the section 

 which M. Boissier ', using a name employed generically by Bernhardi *, 

 has termed Bulbocapjius but which it is perhaps better to follow Irmisch ^ 

 in denominativy Pe5 gallinaceus. This section includes, or should include, 

 ali species with a solid tuber-like corm and with normally, though not by 

 any means universally, a sohiary terminal raceme. Within this section 

 probably most trouble has been experienced in separating satisfactorily 

 those species that bave opposite cauline leaves and bave no leaf-scale on 

 the stem between the corm and the foliage; thèse species constitute 

 Ihe'group of forms to which we may either apply the term Leonticoides, 

 used as a sectional epithet by M. de Gandolle * or the name Cryptoceras,
