In the Flora Indica (1855) Sir J. D. Hooker and Dr. Thomson fonnded a genus 
Dicranostigma on the Indian species here dealt with. This species {Dicranostigma 
lactucoides) was however subsequently referred to Stylophorum by Mr. Bentham and 
Sir J. D. Hooker [Gen. PL 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, Natur. Pjianzenf. iii. 
i. 139 (1891)] that Dicranostigma should rather be referred to Hylomecon Maxim. 
[Prim. FI. Amur. 36, t. 3 (1858)] a genus founded on a plant that was originally 
[Thunbg, Flor. Japon. 221 (1784) ‘,Sieb. 8f Zucc. Abh. Acad'. Muench. iv. ii. 169 (1846)] 
referred to Chelidonium, but that was at a later date [Miguel, 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. Duthie from Kamaon 
(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 C. leptopodum Prain [G-laucium 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.
