3J4 The Irish NaturalisL December, 



region. Tenore, indeed {Ind. Sem. Hort. NeapoL), has a 

 Cineraria ceratophylla^ but this appears to be merely a variety 

 in which the leaves are white above, and not shining green or 

 sparingly pilose, as in the typical plant. Nyman, however 

 {Co7ispeet..,^. 350) places as sub-species under C . 7?tariti7?ia 2l 

 C. calvescg7is (Mor. Dnt.), the name here suggesting a plant 

 less densely tomentose than C ?narifi7na. We are indebted to 

 the courtesy of the Director of Kew Gardens for a transcript 

 of the characters of this plant, and for a tracing of a figure 

 from the work in which it was first published, the Florida 

 Caprari^ of Moris and De Notaris, a Latin flora of the island 

 of Caprera, printed in the Ada of the Royal Academy of 

 Sciences of Turin in 1839. Both plate and distinctive char- 

 acters of the Caprera plant agree rather closely with the form 

 d of the Irish hybrid ; but the plate represents something 

 widely different from the form «, which is the prevalent and 

 characteristic one. The authors of the Florula Capraries 

 describe 6*. calvesce7is as a species, and make no suggestion of 

 hybridism. Indeed, a hybrid origin for the Caprera plant 

 seems improbable, for although both S.Ci7ie7aria and S.Jacobcea 

 occur in the Italian island, the}^ appear there under conditions 

 highly unfavourable to the production of a natural hybrid. 

 The habitat of the first species is given in the Florula as 171 

 rupestribus littoreis : the second is set down as very rare, and 

 occurring (only as a variet}^ of the type) i7i he7-bis secus rivulos, 

 while the authors state that they have not seen the plant in 

 flower. We have had no opportunity of comparing the form b 

 of our Dalkey plant with Caprera specimens of ►S*. calvesce7is, 

 of which there are none in Kew Herbarium, so that we cannot 

 as yet decide whether the plants be identical. So widely, 

 however, does the characteristic form, a, of our hybrid differ 

 from the figure of the Caprera plant that it seems to deserve 

 a distinctive name. The specific adjective albesce7is^ being 

 apparently unappropriated in either of the genera CiTieraria 

 or Se7iecio, we venture to propose for this interesting Irish 

 hybrid the name, x Se7iecio albesce7is. 



The following statement of the distinctive characters of ►b'. 

 alb€scc7is and of its parents is founded on an examination of 

 numerous fresh and dried specimens of all three plants of 

 which fairly typical examples are represented on Plate 5 : —
