In Table I of a paper ^ by one of us theInuleae are shown to be more closely allied in their antherappendages to the Mutisieae and Gynareae than to thetribes among which tliey are usually placed. The typicalstyle of the Inuleae closely approaches some of the Muti-sieae and exceptional Gynareae. From the study of allfactors, including geographical distribution, it seems probablethat the Inuleae gave rise to the Gynareae in the easternpart of the Mediterranean region, through the Buphthal-meae, so that it is not surprising that, in the absence of aninvestigation of the filiform florets, this plant should havebeen classed in the Gynareae. The absence of the ring ofhairs on the style and the character of the anther ap-pendages, however, would, even then, place it nearer the 1 Small, J., Ihe Polleii-jiresentation Mechaiii.siii in Ihe Coinpositae.Anriai.s of Botany, vol. xxix, No. cxv(1915), p. 457.

The fimbrillate receptacle and the barbellato-scabridsetae of the pappus are interesting in view of furtherunpublished work by one of us, which shows tliat thepaleae on the receptacle, especially in the Gynareae, maybe a development of the foveolate and fimbrillate types ofreceptacle, while the plumose pappus is obviously derivedfrom the simple setae by the elongation of the barbs.Altogether the genus Cavea makes quite a probable, al-though somewhat remote, ancestor of Saussurea and itsallies.
