Mr. J. Ball on some British species of the genus CEnantlie. 5 



quentia pedunculos elongates rigidos amplectentia vagina petiolari 

 successive breviori, pinnata pinnulis linearibus tripartitis simpli- 

 cibusve, inferioribus valde elongatis ; suprema caulis et peduncu- 

 lorum linearia elongata. Piamdce foliorum omnium margine carti- 

 lagineo minute denticulate in inucronem producto. Umbellce soli- 

 tariae, terminales, 6 — 15-radiatse, convexte ; accessorise primarium 

 aequantes aut superantes. Involucrum universale nunc nullum, 

 nunc 1 — 6-phyllum ; foliis setaceis, insequalibus, umbella multo 

 hrevioribus. Umbellulse multitioree, densse ; floribus externis 

 saepe sterilibus longius pedicellatis, internis subsessilibus. Invo- 

 lucella polyphylla ; foliuiis lineari-lanceolatis, acuminatis, ina?qua- 

 libus, pedicellos florigeros exteriores subsequantibus. Petala in- 

 aequalia, prsesertim florarum sterilium, lata, obcordata, ad medium 

 fissa, alba nervis coloratis : segmenta marginis calycini liberi lato- 

 lanceolata, iucequalia, duo exteriora longiora. Diaclienium 



iVn (Enanthe gathered in the island of Ischia, which seems to 

 be the CE. pimpinelloides of Bertoloni (Fl, Ital. iii. 236), differs 

 in having the pinnules of all the stem-leaves linear, the sheaths 

 longer, and sometimes wants the sterile external tlorets. The 

 diachenium is of nearly equal thickness throughout, crowned with 

 the erect persistent calyx, and somewhat longer than the stiff, 

 slightly diverging styles ; the very short adpressed pedicels form- 

 ing a callous ring at the base. I have this form also from near 

 Pisa. 



What principally distinguishes this plant is the nuicronate 

 pinnules of all the leaves ; besides which it differs from CE. La- 

 chenalii in the fruit and the iuvolucella, and from (E. silaifolia 

 and CE. peucedanifolia in many ob\ious points. CE. Jonluni, Ten., 

 which I have gathered near Pastum, differs mainly by the very 

 crowded umbel, and the longer sheathing petioles. I do not find 

 all the leaves bipinnate, as Bertoloni describes them, the upper- 

 stem leaves being pinnate with very long linear segments, and 

 ultimately simple linear elongate ; my plant, so far, looking like 

 an intermediate variety. 



I have no doubt as to the identity of the Gloucestershire plant 

 vdth the foreign ones above mentioned, and the Toulouse speci- 

 men referred to by Mr. Babington (Man. Br. Bot. 130) seems 

 to agree with my description, so that CE. pimpinelloides must re- 

 sume its place in the flora of Britain. 



I next come to the CE. peucedanifolia of Smith, Hooker, Ba- 

 bington, and all British botanists, but not of Pollich, or the 

 principal foreign wTiters. I agree with Bertoloni in confirming 

 the opinion of Bieberstein (Fl. Tauro-Caucas. iii. 232), that his 

 CE. silaifolia is the CE. peucedanifolia of Smith (Eng. Bot. t. 348). 

 I foimd this plant in a salt-marsh near Portmarnoch, county 

 Dublin, Ireland, and have received it from the banks of the
