In the Flora Indica (1855) Sir J. D. Hooker and Dr. Thomson founded a genus 

 Dicranostigma on the Indian species here dealt with. This species {Dicranostigma 

 lactucoides) was however subsequently referred to Siylophorum by Mr. Bentham and 

 Sir J. D. Hooker [Gen. PI. i. 53 (1862)], by M. Baillon [Hist. iii. 114 (1871)] and 

 again by Sir J. D. Hooker and Dr. Thomson [_Flor. Brit. Ind. i. 119 (1872)]. More 

 recently Messrs. Prantl and Kundig have suggested [Engler, Natiir. Pfianzenf. iii. 

 i. 139 (1891)] that Dicranostigma should rather be referred to Hylomecon Maxim. 

 [Prim. Fl. Amur. 36, t. 3 (1858)] a genus founded on a plant that was originally 

 [Thunlg, Flor. Japon. 221 (1784) ; Sieb. Sf Zucc. Abh. Acad. Muench. iv. ii. 169 (1846)] 

 referred to Ghelidoniiun, but that was at a later date [Miquel, Prolus. Flor. Japon. 

 199 (1867)] included in Stylophorum ; this genus Mr. Prantl would reinstate. 

 The view expressed by Prantl and Kundig is undoubtedly more tenable than that 

 of the other authors quoted ; at the same time if the method of limitation adopted 

 by them be accepted it would be more advisable to retain Dicranostigma also as a 

 genus. In any case the name of the conjoint genus suggested by Prantl and Kundig 

 must be Dicranostigma, not Hylomecon. But the species in question, formerly very 

 inadequately known, has been recently communicated by Mr. Dathie from Kamaou 

 (its original locality) and by the collectors of the Calcutta garden from Phari in 

 the Eastern Himalaya. A study of these specimens and of the material of the 

 allied groups Stylophorum and Hylomecon, preserved in the national Herbaria at Kew 

 and at the Jardin des Plantes, Paris, shows however that it is impossible to accord 

 generic rank to any of them, or to separate them satisfactorily from each other or 

 from Chelidonium. A detailed review of the species belonging to this widened 

 Chelidonium will be found in the Bulletin of the Boissier Herbarium.

Nearly allied to Chelidonium Franchetianum Prain [in Bull. Herb. Boiss. 

 ined.] and 0. leptopodum Prain [Glaucium leptopodum Maxim. Mel. Biol. ix. 714 

 (1876)], which belong equally to the section Dicranostigma. From both it differs 

 in having large stigmatic lobes, softly hairy capsules, and simple cymes. The 

 section to which these species belong differs from the remaining Chelidonia is having 

 a glaucioid habit-— i. e, radical leaves many rosulate, cauline 0, floral apical all scat- 

 tered.
