Dumorlier's name of Hulthemia and considers rhat the 

 stipules are connale into a leaf. 



In 1865 Bentham and Hooker, Gen. Plant., i, p. 625, 

 speak of the leaves as « 1-foliolate or reduced to stipules. » 

 For them the plant is a true Rose. 



In \S&S Ba'iWoDf Histoh^c des plantes j 1, p. 349, mentions 

 ihe leaves as « réduites à une seule foliole, ou à la base du 

 pétiole, de chaque côté duquel les stipules prennent un grand 

 développement. « 



Boissier in 1872, Flora Orient., I, p. 668, adopts the

 « stipulis aculeiformibus, foliis simplicibus. » He adds

 as a subgenus of Rosa with ihis charaeter : « Blatt einfach,

 there are no stipules, oihers assert ihat the stipules 

 constitute tlie leaves, others ihink that the spines constitute 

 the stipules ! 



It is with the vievv of attempting to reconcile some of 

 thèse discrepaneies that I now venture to give the resuit of 

 my own observations on the living plant.
