FLORA OF SOUTH AMERICA AND THE PACIFIC. 33 



aiul prominent on both sides of the leaves. In the male speci- 

 mens, tlie lower leaves are orbicular and serrated about haU" 

 way down, the upper are obovato-cuneate, 3 — 5-toothed at 

 the apex, all are decidedly clothed (though not white) with 

 small furfuraceous scales. In the two other specimens (fe- 

 male plants), the leaves are all obovate like the upper ones 

 in the male plant and less furfuraceous. In our plant, (female) 

 from Fort Argentino (Tweedie), the leaves are not furfura- 

 ceous, but obscurely dotted, narrow-obovate, coarsely 5 — 7 

 toothed, the nerves rather indistinct. In those (male) speci- 

 mens from Monte Video, the nerves on the leaves are mode- 

 rately conspicuous, the leaves themselves more coriaceous, 

 more oval, indistinctly toothed, and the younger ones espe- 

 cially, rather glutinous than furfuraceous. The female pap- 

 pus is scarcely longer than the involucre, in which respect it 

 seems to differ from De Candolle's female plant ; this how- 

 ever may be owing to the different ages.

 Dr Gillies. — In some respects the foliage of this plant resem- 

 bles the last, but the leaves are generally larger and more 

 attenuated at the base, so as to be almost petiolated. The 

 inflorescence and involucres are quite different.
