2i2 UMBELLiFEE.E. [CHthmum. 



outline, bi-tripinnale, on extremely lunpf, rounded, subnngular petioles, that expand 

 into sLort flat-ribbed and sheatliinof bases, with niembranous margins ; leaflets 

 deep grass-green above, paler and olten somewhat shining beneath, a little (okled 

 or channelled along the course of the midrib above, sessile, narrow-lanceulate or 

 sublinear, attenuated at both ends, simple or deeply bi- or tripartite, the terminal 

 one almost always 3-clefl, very acute and mucronate, the apex purplish, entire 

 but cartilaginous-spin ulose along the somewhat deflexed edges and keel-like mid- 

 rib underneath ; stem-leaves distant, subtending the forks of the branches, the 

 inferior like those of the root, but rapidly becoming smaller, less compound and 

 more petiolate as they ascend, the uppermost often reduced to a simple leaflet. 

 Umbels rather small, loose, of about from 5 to 10 unequal primary rays, which, 

 like those of the umbellets, are furrowed and more or less cartilaginous-scabrous 

 on the angles ; umbellets flattish or slightly convex, many-rayed. Bracts of the 

 general involucre either wanting or of from 1 to 3 unequal, linear, acute, membra- 

 nous-edged leaflets, much shorter than the primary rays ; of the miibellets numerous, 

 broader and somewhat concave, acuminate, with dark tips. Flowers all perfect 

 and equal. Calyx extremely minute, hardly visible. Petals yellowish or greenish 

 white, sometimes dashed with purplish red, suborbicular, traversed longitudinally 

 above by a sharp ridge with a depression on each side, their points broad, iuflexed, 

 caniculate, and mostly somewhat 3-lobed or subtrifid at apex. Styles at first very 

 small, short, greenish and erect, afterwards somewhat larger, spreading and pur- 

 plish ; stylopodes very large and projecting in the flower, greenish yellow, plano- 

 convex, crenate-lobed, at length purplish red and narrower than the ripe fruit. 

 Syndicarps ovate, a little compressed, crowned with the retuse styles and their red 

 bases (stylopodia) ; mericarps separated by a deep fissure, each with 5 sharp, pro- 

 minent, equidistant, almost wing-like ridges, the two lateral ones marginal and 

 rather less prominent; vittts described as numerous by Koch and others, of which 

 4 are commissural (Leighton), but they are so indistinct, in the fruit at least, as 

 to be nearly invisible, nor does Mr. Leighton's excellent transverse section show 

 any. Carpophore bipartite. 



A handsome plant, possessing a powerful aromatic odour like the rind of the 

 bitter orange.

" Fruit elliptical. Carpels spongy, with 5 elevated, sharp, 

 somewhat winged ribs, and, as well as the loose seed, abundantly 

 marked with vittce. Calyx - teeth obsolete. Petals elliptical, 

 entire, involute. (Involucre of many leaves)." — Br. Fl.

On rocks and clifis by the sea ; very abundant, but chiefly along the South and 

 South-western coasts of the island. Fl. June — September. Fr. August — Octo- 

 ber. U- 



E.Med. — At Ventnor. Very common on most parts of the clifls between 

 Ventnor, as near Steephill cove, at Old Park, Sec. In Sandown bay. In clefts 

 of the rock behind Bonchnrch, at a considerable distance from the sea, in several 

 places plentifully. Bembridge clifis, B. T. W. 



W. Med. — On the cliff's at Freshwater Gate and Scratchell's bay. Chalky cliffs 

 from Compton westward. Abundant on the cliff's at Freshwater, Mr. E. Lees 

 (in Baxter's Gen. of Fl. Pis.) 



Fruit (^yndicarjs) ovate-elliptical, convex, purplish, about 2^ lines in length, 

 crowned with the small conical stylopodes, and short mostly recurved styles, 

 glabrous ; hemicatps with 5 thin, elevated, slightly winged, equidistant ridges, of 

 which the lateral pair are quite marginal, the interstices and back jdane, with 

 numerous vilt<E. Seeds brown, narrow-oblong, wrinkled, with many vittas, when 

 mature free by the shrinking (?) of the now corky interior substance of the fruit.
