of the second or middle series in V. chrysostachys, oculata and 

 grandis, and of the first or exterior series in V. callitriclia and 

 ovalifolia, exist in the whole section Catocalypta, and are correctly- 

 figured by Schauer (t. 4. B. fig. 10) ; but these lobes are consi- 

 dered by him as an involucre (!), and described as originating from 

 the "margo exterior loborum," whereas in reality they distinctly 

 spring from the narrow sinus between the lobes, and are perfectly 

 free from the latter : nor do they adhere to the base of the calyx, 

 except in V. insignis, and even here but very slightly. The idea 

 of an involucre springing from the linibus calycis is certainly new, 

 but altogether untenable. According to the differences of the 

 calyx above mentioned, I would propose to divide the genus Ver- 

 ticordia into the following four sections : — 



I. Euveeticoedia, nob. Calycis limbus 1-serialis. 



To this belong Schauer' s whole Sect. I. Euverticordia and 

 III. Chrysonia, and our V. nobilis and stelluligera. 



II. Veeticoedella, nob. Calycis limbus 2-serialis, serie media 

 deficiente, exterioris lobis reflexis integerrimis tubo semiad- 

 natis, &c. 



Of this section I know only V. Drumniondii. 



III. Catocalypta, Schauer. Calycis limbus 2-serialis, serie 

 prima (lobis reflexis integris, &c.) deficiente, &c. 



To this belong all the species of Schauer' s second section, 

 and our V. callitriclia and ovalifolia. 



IV. Penntjligeea, nob. Calycis limbus 3-serialis, &c. 



Of this we know only the three last species here described, 

 V. chrysostachys, oculata and grandis. 



12. ChamjELATJCITTH Detimmokdii, nob., glabrum, foliis sparsis passimque 

 oppositis linearibus triquetris minute mucronulatis subtus obtuse carinatis

 sessilibus, calyce turbinato 10-neryio demum basi obsolete 10-costato, limbi 

 lobis ovalibus obtusis minute ciliolatis, petalis sessilibus orbicularibug

 fertilibus basi dilatatis sterilibusque Hgulseformibus subsequalibus, stylo 

 stamina superante petala sequante, stigmate capitato corona pilorum cincto.
