To judge from Don’s description, his Т. pumilus is identical with our subspecies geranifolius. Of 
great interest in connection with the real nature of the so-called petals is the occurrence in var, bhotanica 
of undoubted staminodes, consisting of filaments of varying lengths and an ellipsoidal empty terminal 
pouch; the number of so-called petals is then reduced to three or four (seo fig. 54). This proves 
conclusively that Prantl’s opinion that the nectariferous petals in Trollius and other genera of 
unculacem are really modified stamens, is correct. In subsp. geranifolius especially the sepals are 
very often persistent and marcescent (вез fig. 6), whilst in T. acuulis they are usually caducous; but
